Standard Precautions-Transmission-Based Precautions Practice Test 5
The nurse is caring for the 4-year-old hospitalized with complications from chicken pox. Which type of precautions should the nurse plan?
- Airborne and droplet precautions with negative- airflow room
- Airborne and droplet precautions with positive- airflow room
- Contact and droplet precautions with negative— airflow room
- Standard precautions with reverse isolation and positive-airflow room
Explanation: Answer reason: A negative-pressure room is used to prevent contaminated air from flowing out of the patient’s room into hallways and other patient-care areas. Positive-pressure rooms are protective environments for immunocompromised patients and would increase the risk of pushing infectious particles outward. Options that omit airborne precautions or use only standard/reverse isolation do not adequately prevent varicella transmission in the hospital.
The nurse is conducting a class for family members of clients diagnosed with tuberculosis (TB). The nurse determines that teaching is effective when the family member states?
- The disease is transmitted by sexual contact.
- The disease is transmitted by contaminated needles.
- The disease is transmitted through contaminated eating utensils.
- The disease is transmitted by droplets exhaled from an infected person.
Explanation: Answer reason: TB is primarily an airborne infection spread when an infected person coughs, sneezes, speaks, or sings, generating droplet nuclei that can remain suspended and be inhaled by others. This statement shows the family understands the true route of transmission that drives prevention measures such as airborne isolation, N95 respirators, and adequate ventilation. Sexual contact and needle exposure are transmission routes for other infections (e.g., STIs, bloodborne pathogens) but not typical for TB. Sharing utensils is not a common transmission mechanism for pulmonary TB, so focusing on respiratory precautions is the key teaching point.
A client with a productive cough, chills, and night sweats is suspected of having active tuberculosis (TB). The most important intervention by the nurse would be?
- Maintain the client on respiratory isolation.
- Prepare the client to be discharged on bed rest.
- Administer the tuberculin test ordered by the physician.
- Administer the isoniazid ordered by the physician immediately before discharge.
Explanation: Answer reason: Suspected active TB is an airborne-transmitted infection, so immediate transmission-based precautions are the priority to protect staff and other clients. Airborne isolation (e.g., negative-pressure room and appropriate respiratory protection) is instituted as soon as TB is suspected, before confirmatory testing. Diagnostic steps like tuberculin testing do not prevent exposure and are not the first safety action. Starting a single drug dose before discharge is unsafe and inadequate for active TB, which requires multi-drug therapy and public health follow-up.
The client is admitted with a positive culture for methicillin-resistant Staphylococcus aureus (MRSA). Which precaution should be implemented to prevent spreading the infection to health care workers and other clients?
- Wearing a mask within 3 feet of the client
- Placing the client in a private room
- Wearing an N95 respirator mask
- Ensuring a negative-air—pressure room
Explanation: Answer reason: A private room (or cohorting with another MRSA-positive client when private rooms are unavailable) limits shared environmental surfaces and decreases spread to other clients. Masks within 3 feet are aimed at droplet precautions, and N95 respirators are for airborne pathogens, neither of which is the primary transmission route for MRSA. Negative-pressure rooms are reserved for airborne isolation (e.g., tuberculosis, measles, varicella), not routine MRSA care.
The nurse cares for a client who is diagnosed with methicillin-resistant Staphylococcus aureus (MRSA) infection. It is important for the nurse to?
- Perform hand hygiene after care of the client.
- Implement droplet precautions for the client.
- Stock the client’s room with dedicated equipment including a stethoscope, thermometer, and blood pressure cuff.
- Eliminate dairy from the client’s diet.
Explanation: Answer reason: MRSA is commonly spread by direct contact, so preventing cross-contamination between patients is a key infection-control priority. Keeping dedicated, single-patient-use equipment in the room reduces organism transfer via shared items (fomites) and supports proper contact isolation practices. Droplet precautions are not the primary transmission-based precaution for typical MRSA colonization/infection; contact precautions are used. Hand hygiene is essential but is a general standard that applies to all patients and does not specifically address the additional environmental/equipment control needed for MRSA.
A client has a past history of vancomycin resistant enterococcus (VRE). The nurse knows for isolation precautions to be discontinued for this client, which must occur?
- The client must no longer complain of headache.
- Results from rectal swab testing must be negative for three weeks.
- Chest x-ray must be negative for infiltrates.
- Nothing because the client will have VRE indefinitely.
Explanation: Answer reason: Contact precautions for VRE are based on whether the organism is still being shed/colonizing the GI tract, not on symptom resolution. Because VRE commonly colonizes the bowel for prolonged periods, discontinuation typically requires documentation of clearance via serial negative surveillance cultures (often rectal/perirectal swabs) over time per facility policy. Headache complaints and chest x-ray findings are unrelated to VRE colonization status and do not determine transmissibility. The statement that VRE is always indefinite is overly absolute; clearance can occur, but must be proven with negative cultures before stopping isolation.
The nurse cares for a client who is diagnosed with methicillin-resistant Staphylococcus aureus (MRSA) and is placed in isolation. The nurse needs to perform an assessment of the client’s wound and administer prescribed medications to the client. The nurse should wear which personal protective equipment (PPE)?
- Gown and gloves.
- Gloves only.
- Gown, gloves, and mask.
- Gown only.
Explanation: Answer reason: MRSA requires contact precautions to prevent transmission via direct contact and contaminated surfaces. When assessing a wound and administering medications in the room, the nurse will have close contact with the client and the immediate environment, so barrier protection for hands and clothing is needed. Gloves protect against hand contamination, and a gown prevents contamination of the nurse’s uniform that could spread organisms to other clients or areas. A mask is not routinely required for MRSA unless there is a risk of splashing or the client has a condition requiring droplet/airborne precautions, which is not indicated here.
A client is placed on contact precautions. A dietary worker brings the client’s lunch using regular dishes. The nurse’s first reaction should be?
- Send the tray back to the dietary department and request the dishes be replaced with disposables.
- Allow the client to eat the lunch.
- Notify the nurse manager immediately.
- Prevent the dietary tray from being taken into the client’s room.
Explanation: Answer reason: Contact precautions primarily require gown/glove use and dedicated equipment when appropriate; they do not require disposable meal trays or dishes in routine hospital practice. Regular dishes can be used if they are handled with standard precautions and sent for normal dishwashing/sanitization, which is sufficient to eliminate pathogens. The immediate priority is ensuring the client receives nutrition without unnecessary delays while maintaining appropriate staff PPE and hand hygiene. Sending the tray back or blocking it from the room adds delay without improving infection control, and escalating to the nurse manager is not the first-line response for a non-hazardous, correctable issue.
The charge nurse is planning a room assignment for the client with meningococcal meningitis. Which room and precautions should the nurse plan for this client?
- A private room with droplet precautions
- A private room with airborne precautions
- A semiprivate room with a roommate who has a similar diagnosis and standard precautions
- A semiprivate room with a roommate who has a similar diagnosis and contact precautions
Explanation: Answer reason: A single room is preferred to reduce exposure risk to other clients and staff, especially during the first 24 hours of effective antibiotic therapy when contagiousness is highest. Airborne precautions are reserved for true airborne pathogens (e.g., tuberculosis, measles), not typical bacterial meningitis. Contact precautions are not the primary isolation method for meningococcal disease because spread is not mainly via contaminated surfaces.
Many persons with active tuberculosis (TB) often first present in ambulatory care settings. What is the first action that should be taken in caring for a client with symptoms of tuberculosis?
- Identify and evaluate the client promptly.
- Instruct the client to cover the mouth and nose with tissues when sneezing or coughing.
- Isolate the client in a negative pressure room.
- Place a surgical mask on the client.
Explanation: Answer reason: Airborne pathogens like suspected TB require immediate source control to reduce droplet nuclei dispersion in a clinic setting before room placement is arranged. Masking the client is the fastest, most reliable first step to protect others in the waiting/triage area while the nurse initiates further infection-control actions. Negative-pressure isolation is appropriate but may not be instantly available and therefore is not the first action in many ambulatory settings. Asking the client to cover coughs is helpful but less effective and more dependent on consistent technique than masking.
A client is admitted to the hospital with influenza. Which action should the nurse take when caring for this client?
- Put the client on droplet precautions.
- Put the client on airborne precautions in a negative pressure room.
- No special precautions are needed for this client.
- Wear an N95 fit tested mask.
Explanation: Answer reason: Influenza is primarily transmitted via respiratory droplets, so transmission-based droplet precautions are indicated in addition to standard precautions. This includes masking for close contact and appropriate patient placement to reduce spread during coughing, sneezing, and talking. Airborne precautions with negative-pressure rooms are reserved for true airborne pathogens (e.g., tuberculosis, measles, varicella), not routine influenza. An N95 respirator is not required for routine care of influenza unless performing aerosol-generating procedures, making it less appropriate as the best general action.
The nurse and NA are caring for the client with hepatitis A. The nurse determines that the NA understands correct infectious precautions for this client when observing what action?
- Wears a mask, gown, and gloves when taking the client’s vital signs
- Wears a gown and gloves when changing the client’s incontinent briefs
- Wears gloves when providing urinary catheter and perineal care
- Wears a gown and gloves when asking the client about snack food options
Explanation: Answer reason: During incontinence care, gown and gloves appropriately reduce skin and clothing contamination and limit spread to the environment. A mask is not routinely required unless there is risk of splashing, so adding a mask for routine vital signs is unnecessary. Asking about snack options does not involve anticipated exposure to body fluids, so extra PPE beyond standard hand hygiene is not indicated.
A client is diagnosed with hepatitis B. When the client reveals this information to family members, the family becomes frightened to go home with the client. Teaching the family to decrease their risk of exposure to hepatitis B includes which information?
- Do not share personal items with the client, such as razors or toothbrushes.
- Wash dishes in separate water to decrease the risk of contamination.
- Do not hug or kiss the client.
- Use a separate bathroom from the client.
Explanation: Answer reason: Hepatitis B is transmitted through exposure to infected blood and certain body fluids, so prevention teaching focuses on avoiding blood-to-blood contact in the home. Items that can be contaminated with microscopic blood (e.g., razors, toothbrushes) are common household sources of exposure risk and should never be shared. Casual contact such as hugging or kissing does not transmit hepatitis B, so restricting normal social contact is unnecessary. Hepatitis B is not spread by shared bathrooms or by dishes when routine cleaning is used, making separate bathroom use or special dishwashing practices nonessential.
The home health nurse administers directly observed therapy (DOT) to a client who was diagnosed with pulmonary Mycobacterium tuberculosis (MTB) nine days ago. At that time the client was started on TB chemotherapy regimen. Which personal protective equipment (PPE) should the nurse wear when making her first intake visit at the client’s home?
- Eye shield and gloves.
- A surgical mask.
- No PPE is required.
- A fit-tested respirator.
Explanation: Answer reason: Airborne transmission requires a particulate respirator (e.g., N95 or higher) for anyone entering the room/area of a patient with suspected or confirmed pulmonary TB until the patient is no longer considered infectious. After only 9 days of therapy, many patients can still be contagious, and home visits lack engineered airborne controls like negative-pressure rooms, so respiratory protection remains essential. A surgical mask does not filter airborne droplet nuclei adequately to protect the nurse. Eye protection and gloves alone do not address the primary airborne route of MTB transmission.
The nurse cares for a client who recently delivered a baby. The client has a 10-mm reaction to a tuberculin (TB) skin test as measured on her left arm. The client does not have any symptoms, and chest x-ray is negative. The baby develops respiratory distress and is placed in the neonatal intensive care unit. The nurse should?
- Place the mother on airborne precautions.
- Place the baby on airborne precautions.
- Leave the mother and baby in a regular, nonisolated hospital room.
- Place a mask on the mother to prevent infecting the baby during visitation.
Explanation: Answer reason: A positive TB skin test with no symptoms and a negative chest x-ray indicates latent TB infection, which is not contagious because there is no active pulmonary disease and no airborne organisms being expelled. Airborne precautions are reserved for suspected or confirmed active pulmonary or laryngeal TB, especially when cough, systemic symptoms, or abnormal imaging are present. The infant’s respiratory distress in the NICU does not, by itself, imply TB exposure requiring airborne isolation without evidence of active maternal disease. Adding a mask or isolating either patient would be unnecessary and inconsistent with transmission-based precaution principles for latent TB.
A 20-year-old college student who lives in a dormitory is admitted to the emergency department with complaints of headache, nausea, vomiting, stiff neck, and a rash. The nurse should perform which action based on the information given?
- Wear a fit-tested N95 mask when caring for the client.
- Implement droplet precautions when caring for the client.
- Use airborne precautions and place the client into a negative pressure room.
- Implement standard precautions when caring for the client.
Explanation: Answer reason: The constellation of fever-like symptoms with headache, stiff neck, and rash in a dorm resident is highly concerning for meningococcal meningitis, which spreads via respiratory droplets. Transmission-based precautions should be initiated immediately to reduce exposure to staff and other patients while diagnostic workup proceeds. Airborne isolation/negative-pressure is reserved for true airborne pathogens (e.g., TB, measles, varicella), not typical meningococcal disease. Standard precautions alone are insufficient because they do not address droplet spread during close contact (e.g., within 3–6 feet) or procedures that generate cough/sneeze droplets.
While the nurse performs a hospital admission assessment, the client complains of night sweats, productive cough with blood-tinged sputum, fever, and weight loss. Chest x-ray shows an upper lobe infiltrate. The nurse should implement which precautions?
- Standard precautions only.
- Standard precautions and airborne precautions.
- Standard precautions and droplet precautions.
- Standard precautions, airborne precautions, and use of a negative pressure room.
Explanation: Answer reason: The symptom cluster of night sweats, weight loss, hemoptysis, fever, and an upper-lobe infiltrate strongly suggests pulmonary tuberculosis, which is transmitted via airborne droplet nuclei. Suspected TB requires immediate transmission-based airborne isolation in addition to standard precautions to protect staff and other patients. Airborne isolation includes placement in an airborne infection isolation room with negative pressure to prevent contaminated air from escaping into hallways. Droplet precautions are insufficient because they do not address the smaller aerosolized particles that remain suspended and travel farther than large droplets.
A team leader would instruct team members to wear a mask and protective eyewear or a face shield in which situation?
- When strong odors are emitted from an infected wound
- When the client has an oral temperature greater than 101° F (38.3° C)
- If needles or other sharp instruments are to be used in the procedure
- During a procedure where splashing of blood or body fluid is anticipated
Explanation: Answer reason: A mask plus goggles/face shield is indicated when sprays or splashes are likely because these routes can transmit pathogens via droplets contacting conjunctiva or oropharyngeal mucosa. Fever alone does not determine the need for facial protection unless a specific respiratory transmission risk is present. Sharps use primarily calls for safe handling and appropriate gloves, not routine mask/eye protection unless splash risk exists.
The new nurse is caring for the client with a VRE infection. Which statement to the client indicates the new nurse needs additional orientation when caring for clients with a VRE infection?
- "All hospital staff should be wearing gown and gloves when they enter your room."
- "Visitors should use soap and water for hand washing when entering and leaving your room."
- "You are in a private room because VRE is transmitted by direct and indirect contact."
- "VRE is a new strain of enterococci bacteria normally found in a person’s GI tract."
Explanation: Answer reason: " VRE requires contact precautions and meticulous hand hygiene, but routine handwashing with soap and water is not the required method for all encounters. Alcohol-based hand rub is acceptable and commonly preferred when hands are not visibly soiled, with soap and water reserved when soiling is present or specific organisms (e.g., spores) are suspected. Stating that visitors “should use soap and water” as the expectation implies an incorrect, overly rigid requirement and reflects misunderstanding of standard hand-hygiene guidance. By contrast, emphasizing gown/gloves on room entry and private room placement aligns with contact transmission prevention.
The nurse is supervising the NA caring for a group of clients with antibiotic-resistant organisms. Which observation of the NA’s performance should prompt the supervising nurse to intervene?
- Uses an alcohol-based hand hygiene after emptying the urinary drainage bag of the client with vancomycin—resistant enterococci (VRE)
- Performs hand hygiene then dons gloves to perform oral care for the client with B—lactamase—producing Klebsiella pneumoniae
- Uses an alcohol-based hand rub and wears gloves before and after taking the temperature of the client with penicillin G—resistant Streptococcus pneumoniae
- Tells visitors to use the alcohol—based hand wash when entering and leaving the room of the client with methicillin-resistant Staphylococcus aureus (MRSA)
Explanation: Answer reason: Alcohol-based hand rub is not appropriate when hands are visibly soiled or after exposure to certain organisms where soap-and-water is indicated; emptying a urinary drainage bag is a high-risk task for contamination and environmental spread. The safer, guideline-consistent action is to wash hands with soap and water after glove removal for this type of exposure. The other observations reflect appropriate baseline practices (hand hygiene before gloving, gloves during care, and promoting hand hygiene for visitors).
The nurse is providing postmortem care for a client who was being treated for Staphylococcus aureus. Which transmission-based precautions are indicated?
- Airborne precautions
- Contact precautions
- Droplet precautions
- Standard precautions
Explanation: Answer reason: During postmortem care, body fluids and any draining lesions can contaminate surfaces and the nurse’s hands/clothing, making gown and gloves with dedicated equipment appropriate. Airborne precautions are reserved for pathogens that remain suspended in air (e.g., TB), which is not the typical route for S. aureus. Standard precautions apply to all clients, but the question asks specifically for the indicated transmission-based category, which is contact.
The nurse is observing a student nurse wash their hands with soap and water. Which observation requires follow-up? The student nurse?
- Washes their hands using warm water.
- Dries hands thoroughly from wrists to fingers with paper towel.
- Wets their wrists and hands with fingers pointed downward.
- Pushes wristwatch and long uniform sleeves above wrists.
Explanation: Answer reason: Effective hand hygiene requires removing jewelry and keeping forearms free of items that can harbor microorganisms and prevent thorough friction over all skin surfaces. A wristwatch is a known reservoir for pathogens and interferes with proper cleansing of the wrist area, so it should be removed rather than simply pushed up. Using warm water, keeping fingers pointed downward to prevent contaminated water from running toward the forearms, and drying from wrists to fingers are consistent with recommended technique to reduce contamination. Leaving a watch in place increases the risk of incomplete handwashing and cross-transmission, so this finding warrants follow-up teaching.
The client’s wife states she doesn’t like to wear a mask. The nurse’s response should be?
- If you don’t like it, you don’t need to wear it.
- You may be sick and not know it. It’s best not to spread germs.
- Your husband’s body is working hard to fight this infection. Another one will make it worse.
- I understand it can be uncomfortable. This is to help protect your husband from catching any germs that we may carry.
Explanation: Answer reason: I understand it can be uncomfortable. This is to help protect your husband from catching any germs that we may carry. Effective infection control teaching combines empathy with a clear, patient-centered rationale to promote adherence to precautions. This response acknowledges the visitor’s discomfort and explains the safety purpose of masking—reducing transmission of microorganisms to a potentially vulnerable patient. It avoids judgment or fear-based language, which can increase resistance and decrease cooperation. In contrast, dismissing the requirement undermines standard precautions, and focusing on whether the visitor is “sick” can sound accusatory while missing the key goal of protecting the immunocompromised or infected client.
The nurse in the emergency department is caring for a child with nuchal rigidity, fever, photophobia, and rash. The nurse should initially?
- Provide the client a tepid sponge bath.
- Initiate droplet precautions.
- Prepare the client for a lumbar puncture.
- Prepare the client for a computed tomography scan of the brain.
Explanation: Answer reason: The immediate nursing priority with suspected meningitis/meningococcemia (fever, nuchal rigidity, photophobia, rash) is preventing transmission to staff and other patients. Droplet precautions should be started promptly because Neisseria meningitidis spreads via respiratory droplets, and delays increase exposure risk. Diagnostic steps like lumbar puncture or CT may be necessary, but they do not come before instituting appropriate isolation. Comfort measures such as a tepid sponge bath can be supportive but are not the first action when a highly contagious, potentially life-threatening infection is suspected.
A nurse is caring for a child presenting with a productive cough, with blood-tinged sputum and SPO2 of 95% on room air. Which of the following actions should the nurse prioritize?
- Initiate anti-TBs as prescribed
- Administer oxygen as prescribed
- Initiate airborne precautions
- Perform a chest X-ray
Explanation: Answer reason: The child is not in acute respiratory failure (SpO2 95% on room air), so oxygen is not the most time-critical first action. Diagnostics (e.g., chest X-ray) and treatment initiation are important but should occur after implementing infection-control measures to prevent exposure. Prioritizing isolation aligns with safety and infection control principles and reduces risk of facility-wide transmission.
A nursing instructor is monitoring the care of a new graduate nurse on a med-surg unit. A client culture results come back positive for the flu. Which of the following actions by the new graduate nurse requires further education by the instructor?
- Washing the hands when entering and leaving the clients room
- Obtaining an order to place the client on droplet precautions
- Enacting an NPO status for the client due to nausea and vomiting
- Ensuring the client wear a mask during transport throughout the hospital
Explanation: Answer reason: Influenza spreads via respiratory droplets, so promptly implementing droplet precautions reduces transmission risk to staff and other patients. Hand hygiene on entry/exit is a core infection-control measure and is appropriate. Masking the patient during transport is also consistent with droplet precautions to contain respiratory secretions; nausea/vomiting may warrant antiemetics and hydration but does not justify making the patient NPO as an infection-control step.
The charge nurse is observing a staff member caring for a client who has a methicillin-resistant Staphylococcus aureus infection of a sacral wound. Which of the following actions by the staff member would indicate to the charge nurse an understanding of the principles of infection control for this client?
- Wears a gown, gloves, and a face shield when irrigating the wound
- Places a “soap and water only” sign visible at the entrance to the room
- Assigns the client to a shared room with a client who has varicella zoster
- Discontinues precautions when the wound culture is negative after 1 day of growth
Explanation: Answer reason: Wound irrigation can aerosolize or splash contaminated fluid, so a gown and gloves protect skin and clothing and a face shield protects mucous membranes of the eyes, nose, and mouth. Posting a “soap and water only” sign is more consistent with suspected/confirmed C. difficile, not MRSA. Precautions should not be stopped based on an early negative culture result because cultures may take longer to grow and clinical risk of transmission remains.
The nurse supervises wound care being performed by a family member for a patient with cellulitis to the arm. Which action implemented by the patient's family member requires correction by the nurse?
- Maintaining contact precautions during the procedure.
- Outlining and dating the red areas on the affected arm.
- Positioning the infected arm on a flat surface.
- Wrapping the affected arm with a warmed towel.
Explanation: Answer reason: Cellulitis is typically managed with standard precautions because it is an infection of the deeper dermis/subcutaneous tissue and is not inherently spread by casual contact unless there is uncontrolled drainage. Contact precautions are reserved for pathogens or situations with significant risk of transmission via contact (e.g., MRSA with draining wounds, uncontrolled secretions/excretions). Using contact precautions when not indicated reflects incorrect infection-control practice and should be corrected to the appropriate precaution level. Marking and dating erythema helps track progression, limb positioning can support comfort and care, and warm moist compresses are commonly used as supportive therapy when ordered and safe.
The nurse is planning care for a client with acute hepatitis A. Which of the following should be included in the plan of care for an infant with an acute hepatitis A virus (HAV) infection?
- Place the client on droplet precautions
- Inform caregiver there is no current vaccine for HAV
- Recommend caregivers wear gloves during diaper changes
- Offer the mother HAV testing to be sure she didn't infect infant during childbirth
Explanation: Answer reason: Gloves during diaper changes are a practical application of standard precautions to prevent spread to caregivers and other contacts. Droplet precautions are not indicated for HAV because it is not spread through respiratory droplets in routine care. There is an effective HAV vaccine, and vertical transmission during childbirth is not the typical transmission pathway for hepatitis A.
The nurse should initiate which type of precautions for a child with Fifth’s disease?
- Airborne
- Contact
- Contact plus
- Droplet
Explanation: Answer reason: Droplet precautions (mask within close contact, private room or cohorting, and standard hand hygiene) address this route of spread. Airborne precautions are reserved for organisms that remain suspended over long distances (e.g., measles, varicella, TB), which does not apply here. Contact precautions are not the primary requirement unless there are copious secretions or other indications, so droplet is the best single choice.
The nurse is planning a staff education program about N95 respirators. Which of the following information should the nurse include?
- The initial respirator fitting will be valid throughout employment.
- If the respirator is damaged, a surgical mask may be substituted.
- Leave the N95 respirator mask on when leaving the isolation room.
- Respiratory syncytial virus (RSV) requires the nurse to wear a respirator.
Explanation: Answer reason: Transmission-based precautions are selected based on how an organism spreads, and airborne pathogens require a fit-tested respirator to prevent inhalation of small aerosolized particles. Teaching should therefore emphasize which infections warrant N95 use rather than implying respirators can be casually substituted or used inconsistently. Fit testing is not a one-time event for an entire career; it must be repeated per policy and when facial/weight changes could affect seal. Removing a respirator should occur after leaving the room and closing the door (per facility protocol) to avoid contaminating clean areas and to maintain protection during exit.
Which of the following is not a bloodborne pathogen that can be contracted with a needlestick injury?
- Hepatitis A
- Hepatitis B
- Hepatitis C
- HIV
Explanation: Answer reason: Hepatitis B, hepatitis C, and HIV are classic bloodborne pathogens with documented occupational transmission risk after percutaneous injury. Hepatitis A is mainly transmitted by the fecal–oral route and is not typically acquired through blood exposure from a needlestick in routine clinical settings. This distinction underlies standard precautions and post-exposure protocols that focus on HBV, HCV, and HIV risk assessment and follow-up.
The nurse suspects a child in the emergency department is suffering from rubella. Which isolation precautions should be implemented?
- Airborne
- Contact
- Contact plus
- Droplet
Explanation: Answer reason: Droplet precautions require a surgical mask for caregivers within close contact and appropriate patient placement to reduce exposure to others in the ED. Airborne precautions are reserved for infections with true airborne spread (e.g., measles, varicella, TB), which is a common confusion with viral exanthems. Contact precautions are mainly for pathogens spread by direct touch or contaminated surfaces and are not the primary route for rubella.
A nurse is utilizing PPE to decrease the risk of infection. Which part of the PPE should be removed first?
- Eye protection
- Gloves
- Gown
- Mask
Explanation: Answer reason: Gloves are considered the dirtiest because they have the most direct contact with patient secretions and contaminated surfaces. Removing them first allows immediate hand hygiene before touching other PPE ties/straps that could transfer organisms to the face or clothing. A common error is removing the mask or eye protection early, which increases risk of inoculating mucous membranes during removal.
A patient is admitted with a diagnosis of varicella. Which type of transmission precaution would be appropriate for this patient?
- Airborne
- Contact
- Droplet
- Standard
Explanation: Answer reason: Airborne precautions reduce inhalation exposure risk for susceptible staff and patients, which is the primary safety concern in inpatient settings. Contact precautions are also used in practice, but if only one category must be selected, airborne best captures the high-risk route. Droplet precautions are insufficient because they do not address smaller particle suspension in air, and standard precautions alone do not prevent transmission to non-immune individuals.
The infection control nurse reviews guidelines with other nurses. Which of the following statements by the nurses would indicate a correct understanding of the teaching?
- "The nurse should wear a surgical mask when transporting a client with active pulmonary tuberculosis (TB)."
- "Disposable utensils must be provided for a client infected with hepatitis B."
- "A surgical mask should be worn when working within three feet of the client infected with Neisseria meningitidis."
- "A surgical gown should be applied when entering a client's room with bacterial pneumonia."
Explanation: Answer reason: "Neisseria meningitidis is spread primarily by respiratory droplets, so droplet precautions are required in addition to standard precautions. Droplet precautions include wearing a surgical mask when within close range of the patient (commonly cited as within 3 feet) to prevent mucous membrane exposure. In contrast, active pulmonary TB requires airborne precautions with an N95 respirator (not a simple surgical mask) for staff, making that statement incorrect. Hepatitis B is transmitted via blood/body fluids and does not require special food/utensil disposal, and uncomplicated bacterial pneumonia typically calls for droplet precautions rather than routine gown use unless contact with secretions is anticipated.
A client is diagnosed with methicillin-resistant staphylococcus aureus pneumonia. What type of isolation is most appropriate for this client?
- Reverse isolation
- Respiratory isolation
- Contact isolation
- Standard precautions
Explanation: Answer reason: MRSA is primarily transmitted by direct contact with contaminated hands, equipment, or environmental surfaces, so contact precautions are required in addition to standard precautions. This includes gown and gloves upon room entry and dedicated or disinfected equipment to prevent cross-transmission. “Respiratory isolation” is used for pathogens that spread via airborne or droplet routes as the dominant mechanism, which is not the key control point for MRSA. Reverse isolation is intended to protect severely immunocompromised clients from acquiring infections, not to contain MRSA from spreading to others.
The nurse is admitting a patient with a diagnosis of measles. What is the appropriate transmission precaution for the nurse to initiate?
- Airborne
- Contact
- Droplet
- No precautions needed
Explanation: Answer reason: Measles (rubeola) is one of the most contagious infections and spreads via airborne transmission from aerosolized respiratory particles that can remain suspended and travel in the air. This requires airborne precautions, including a fit-tested N95 (or higher) respirator and placement in a negative-pressure room when available. Droplet precautions are insufficient because they target larger particles that travel short distances, whereas measles can spread beyond 3–6 feet and linger after the patient leaves. Initiating the correct isolation promptly is a key infection-control action to prevent healthcare-associated transmission, especially to susceptible staff and other patients.
A nursing intervention for a patient with hepatitis B would include which of the following types of isolation?
- Universal precautions
- Blood transfusions
- Enteric isolation
- Strict isolation
Explanation: Answer reason: This includes consistent hand hygiene and appropriate PPE (especially gloves) when anticipating contact with blood, body fluids, or contaminated sharps/needles. Enteric isolation targets fecal-oral pathogens (e.g., C. difficile) and does not address the main transmission route for hepatitis B. “Strict isolation” is not indicated for hepatitis B in typical healthcare settings and would represent unnecessary restriction compared with evidence-based precautions.
Which of the following nursing procedures when preforming tracheostomy care is inappropriate?
- Use clean technique for dressing care
- Use clean technique for suc
- Maintain sterility when cleaning the inner cannula
- Maintain oxygenation during procedure
Explanation: Answer reason: Using only clean technique during suctioning increases the chance of contaminating the trachea and lungs with skin or environmental flora. By contrast, dressing care is often performed with clean technique unless the institution requires sterile supplies, and maintaining oxygenation is essential because suctioning can rapidly cause hypoxemia. Keeping the inner cannula sterile while cleaning also aligns with infection-prevention principles because it will be reinserted into the airway.
The nurse is caring for a patient with hepatitis B. The nurse understands that high risk groups for acquiring this virus include which of the following?
- Food workers
- College students
- Elderly patients
- Hemodialysis nurses
Explanation: Answer reason: Hemodialysis settings involve frequent vascular access, blood handling, and potential needlestick or mucosal exposures, which increases transmission risk if precautions fail. Standard precautions, safe injection practices, and vaccination are especially important for staff in these environments. In contrast, food handling is not a typical transmission route for hepatitis B, which is not spread via casual contact or food.
The nurse is admitting a newborn with a low-grade fever, high-pitched whooping cough, and cyanosis. The nurse should arrange which type of precautions for this patient?
- Airborne precautions
- Contact precautions
- Droplet precautions
- No precautions needed
Explanation: Answer reason: A newborn with paroxysmal “whooping” cough and cyanosis is high risk for severe disease and can shed organism-laden secretions during coughing fits, making source control essential. Droplet precautions (mask within close range, private room/cohorting, standard precautions) directly target this route of transmission. Airborne isolation is reserved for organisms that remain suspended over long distances (e.g., TB, measles, varicella), which is not the typical mode for pertussis. Contact precautions alone would not adequately address spread via large respiratory droplets during coughing episodes.
A nurse provides care to a client with a Clostridioides difficile (C. diff.) infection. Which infection control precaution does the nurse implement?
- Wear a disposable mask when having direct client contact.
- Wear a gown and gloves when providing client care.
- Use hand sanitizer when leaving the client’s room.
- Move the client to a room near the nurse’s station.
Explanation: Answer reason: C. difficile is transmitted via spores through the fecal–oral route, so contact precautions are required to prevent organism spread via hands and clothing. Gown and gloves during care reduce contamination of the nurse’s skin and uniform and limit environmental transmission. Alcohol-based hand sanitizer is unreliable against spores, so soap-and-water hand hygiene is needed instead, making that choice unsafe. A mask is not routinely indicated because C. diff is not spread by droplet or airborne routes, and room placement near the nurses’ station does not address the mode of transmission.
In accordance with standard precaution guidelines, when should a nurse wear gloves during nursing interventions?
- Taking a patient’s blood pressure
- Assisting a patient with eating
- Taking care of a patient’s hair
- Performing oral hygiene tasks
Explanation: Answer reason: Gloves are required when there is potential contact with bodily fluids such as saliva. Oral hygiene exposes the nurse to mucous membranes and secretions, requiring standard precautions.
Several clients are admitted to an adult medical unit. The nurse would ensure airborne precautions for a client with which of the following medical conditions?
- A diagnosis of AIDS and cytomegalovirus
- A positive PPD with an abnormal chest x-ray
- A tentative diagnosis of viral pneumonia
- Mycoplasma pneumonia
Explanation: Answer reason: A positive PPD plus an abnormal chest radiograph raises concern for active TB disease until proven otherwise, so the client should be placed in an airborne infection isolation room with N95/respirator use. In contrast, viral and mycoplasma pneumonias are typically managed with droplet (and standard) precautions rather than airborne, and AIDS/CMV does not by itself indicate airborne isolation. The safest nursing action is to implement airborne precautions immediately while diagnostic confirmation is pursued to prevent unit-wide transmission.
A client diagnosed with active TB would be hospitalized primarily for which of the following reasons?
- To evaluate his condition.
- To determine his compliance.
- To prevent spread of the disease.
- To determine the need for antibiotic therapy.
Explanation: Answer reason: Active tuberculosis is an airborne infection, so the highest priority is protecting others via rapid initiation of airborne isolation (negative-pressure room) and ensuring transmission-based precautions are followed. Hospitalization is primarily indicated when isolation cannot be reliably maintained or when public health risk is significant, because untreated or inadequately isolated active TB can spread through droplet nuclei. Evaluating condition and determining medication needs can often be done outpatient once diagnosis is established, and TB treatment is generally indicated rather than contingent on inpatient observation. Assessing compliance is important (e.g., DOT), but it is not the primary reason for hospitalization compared with immediate infection-control needs.
The nurse is caring for four clients on a medical-surgical floor. Which client requires immediate isolation precautions?
- A client with pneumonia producing yellow sputum and a fever of 38.3°C (101°F).
- A client newly diagnosed with tuberculosis (TB) who reports coughing up blood-tinged sputum.
- A client with influenza who complains of body aches and sore throat.
- A client with Clostridioides difficile (C. diff) infection with frequent watery diarrhea.
Explanation: Answer reason: TB is transmitted via airborne droplet nuclei that remain suspended and can infect others at a distance, so it requires rapid implementation of airborne precautions to prevent unit-wide exposure. A new TB diagnosis with cough (including hemoptysis) indicates potential infectious pulmonary TB until proven otherwise, warranting immediate placement in an airborne infection isolation room and use of an N95 respirator. By contrast, influenza is typically managed with droplet precautions, and routine bacterial pneumonia is usually standard (or droplet in select situations) rather than airborne. Although C. difficile requires contact precautions with soap-and-water hand hygiene, the broader immediate airborne transmission risk on a med-surg floor makes suspected infectious TB the highest priority for prompt isolation.
Newly hired nurse Liza is excited to perform her very first physical assessment with a 19-year-old client. Which assessment examination requires Liza to wear gloves?
- Breast
- Integumentary
- Ophthalmic
- Oral
Explanation: Answer reason: An oral exam involves direct contact with the mouth’s mucous membranes and saliva, so gloves are indicated to reduce transmission risk and protect the nurse from exposure. By contrast, routine breast, integumentary, and ophthalmic assessments typically involve intact skin only and do not inherently require gloves unless there are open lesions, drainage, or other exposure risks. Therefore, the oral examination is the one that requires gloves in a standard physical assessment.
A patient with influenza is experiencing tachycardia, tachypnea, fever, and dyspnea. The patient presses his call light and tells the nurse through the phone that he is feeling worse, and is having trouble taking a deep breath. The nurse’s best response is?
- Tell the patient she’ll be back in the room at the next assessment time
- Tell the aide to take the patient some juice
- Don protective personal equipment and reassess the patient
- Ask the provider for additional medication
Explanation: Answer reason: Because influenza is transmitted via droplets, the nurse must apply appropriate precautions before entering to protect self and prevent spread while still responding urgently. Reassessment allows rapid evaluation of oxygenation (work of breathing, SpO2, lung sounds) and timely escalation (oxygen, rapid response) based on findings. Deferring care or sending juice does not address the respiratory threat, and calling for more medication is premature without an in-person assessment of severity and needs.
There are four clients with infections in the ED and only one private room is available. Which among the clients is the most appropriate to occupy the private room?
- A client with a cough who may have tuberculosis
- A client with toxic shock syndrome and a temperature of 102.4°F (39.1°C)
- A client with diarrhea caused by C. difficile
- A client with a wound infected with Vancomycin-resistant enterococci (VRE)
Explanation: Answer reason: Suspected pulmonary tuberculosis should be placed in a private negative-pressure room (airborne isolation) as soon as possible to reduce exposure risk in a crowded ED. Contact-transmitted infections like C. difficile and VRE also benefit from private rooms, but they are primarily spread through direct contact and can often be managed with strict contact precautions and dedicated equipment if a private room is limited. Toxic shock syndrome is not typically managed with transmission-based isolation beyond standard precautions unless another specific transmissible infection is suspected.
