Question 1

Which assessment of hearing involves the use of a tuning fork placed on top of the patient’s head?

Accepted Answer

Answer reason: This helps distinguish conductive from sensorineural hearing loss based on lateralization of sound to one ear. In contrast, the Rinne test compares air conduction to bone conduction by placing the tuning fork on the mastoid process and then near the ear canal, not on the head’s midline. McMurray is for meniscal knee injury and Schamroth assesses clubbing, so they are unrelated to hearing assessment.

Question 2

Which of the following would lead to an inaccurately low reading of blood pressure?

Accepted Answer

Answer reason: If the arm is positioned above heart level, the measured arterial pressure at the cuff is lower than central (heart-level) pressure, producing a falsely low reading. In contrast, crossing legs and talking commonly increase sympathetic tone or alter venous return, tending to yield falsely high readings. Using a cuff that is too small also overestimates blood pressure due to excessive cuff pressure needed to occlude the artery.

Question 3

What is the Glasgow coma scale used to assess?

Accepted Answer

Answer reason: These domains reflect cortical and brainstem function and help trend neurologic status over time in conditions like head injury or stroke. Pupillary response and specific cranial nerve testing are important neurologic checks but are not components of the GCS scoring system. Memory testing also does not contribute to the GCS and is assessed with other cognitive screening methods.

Question 4

The nurse assesses a patient and finds that they have a normal anteroposterior-to-transverse (AP:T) diameter. What is the expected ratio in an adult?

Accepted Answer

Answer reason: This makes the expected AP:T ratio approximately 1:2 on inspection/palpation during respiratory assessment. A 1:1 ratio suggests an increased AP diameter (barrel chest), commonly associated with chronic hyperinflation such as COPD/emphysema. Ratios like 2:1 or 3:1 would imply an implausibly greater AP than transverse diameter for a normal adult thorax.

Question 5

Which of the following findings does the nurse anticipate when percussing over an area of pneumothorax?

Accepted Answer

Answer reason: Pneumothorax classically yields hyperresonance on percussion over the affected area because the underlying lung is not apposed to the chest wall. In contrast, dullness or flatness suggests increased tissue density such as consolidation, pleural effusion, or a solid organ rather than free air. Normal aerated lung is typically resonant, so a shift to a more “booming” note supports pneumothorax.

Question 6

The emergency department (ED) nurse triages a client with suspected bacterial meningitis. The nurse plans on assessing the client for Kernig's sign. The nurse understands that this sign is positive when the client?

Accepted Answer

Answer reason: Kernig’s sign reflects meningeal irritation: with the hip flexed (typically to 90 degrees), attempting to extend the knee stretches inflamed meninges and produces pain and/or resistance. This finding supports suspicion of meningitis and is a classic focused neurologic assessment in acute evaluation. Neck stiffness with passive neck flexion describes nuchal rigidity/Brudzinski-related findings rather than Kernig’s. Forearm spasm with BP cuff inflation is Trousseau sign (hypocalcemia), and calf pain with dorsiflexion is Homan sign (DVT), both unrelated to meningitis.

Question 7

The nurse is conducting a neurological assessment on a patient admitted to the emergency department. Using the Glasgow Coma Scale (GCS), the nurse observes that the patient only opens his eyes to a voice, is confused and disoriented but able to detect painful stimuli. Which of the following scores should the nurse document for this patient?

Accepted Answer

Answer reason: Eye opening to voice is E3, and being confused/disoriented corresponds to a confused verbal response V4. The ability to detect painful stimuli implies purposeful movement/localizing pain rather than withdrawal, giving M5. Adding 3 + 4 + 5 yields a total of 12, indicating moderate impairment and supporting the selected score over lower or near-normal totals.

Question 8

A nurse is teaching a group of students about bowel sounds. Which of the following statements reflects a normal finding?

Accepted Answer

Answer reason: Normal bowel sounds are intermittent, soft-to-moderately loud clicks and gurgles produced by peristalsis and movement of gas/fluid through the intestines. This description best matches the expected qualitative character of normal sounds across abdominal quadrants. In contrast, sounds that are absent for more than 5 minutes suggest ileus or significant hypomotility and are not normal. A fixed low frequency such as “twice in a minute” is too slow for typical normoactive patterns, and “always loud and rhythmic” is inaccurate because intensity and rhythm normally vary.

Question 9

A nurse assesses a client's surgical incision for signs of infection. Which finding by the nurse would be interpreted as a normal finding at the surgical site?

Accepted Answer

Answer reason: This finding is expected as long as it is not excessive and is not accompanied by progressive erythema, increasing pain, or systemic symptoms. Purulent drainage suggests bacterial infection and requires prompt evaluation. Warmth, tenderness, and red, hard skin are more concerning for localized inflammation/cellulitis or an evolving wound infection rather than a routine, normal incision finding.

Question 10

The nurse is observing a student nurse perform a physical assessment. It would demonstrate appropriate technique if the student assessed for stereognosis by instructing the client to?

Accepted Answer

Answer reason: Stereognosis tests cortical sensory function (parietal lobe) by assessing the ability to recognize an object by touch without visual input. The correct technique is to have the client close the eyes, place a familiar object in the hand, and ask for identification. The Romberg test (standing with feet together and eyes closed) evaluates proprioception/vestibular function rather than object recognition. Heel-to-toe/heel and toe walking and finger-to-nose primarily assess cerebellar coordination and gait, not stereognosis.

Question 11

A nurse in the emergency department is assessing a patient who reports chest pain, nausea, and shortness of breath. The ECG shows ST elevation in leads II, III, and aVF. Which of the following actions should the nurse take first?

Accepted Answer

Answer reason: The immediate nursing priority is rapid detection of life-threatening rhythm changes and ischemic instability so that defibrillation, pacing, and ACLS interventions can be delivered without delay. Continuous monitoring also provides a baseline rhythm and ongoing assessment while other time-sensitive steps (vital signs, IV access, 12-lead confirmation, labs, and reperfusion activation) are initiated. Giving nitroglycerin first can be unsafe in inferior/right-ventricular involvement due to preload dependence and potential precipitous hypotension, so monitoring and assessment should precede it.

Question 12

A nurse is admitting a patient with suspected rheumatic fever. Which assessment should the nurse do first?

Accepted Answer

Answer reason: A focused cardiovascular assessment directly evaluates the most life-threatening complication and establishes a baseline for ongoing monitoring and provider notification. Abdominal findings are not the hallmark of rheumatic fever and are lower priority unless specific GI symptoms are present. Deep tendon reflex testing does not address the primary acute risk; neurologic evaluation is more targeted to chorea and would typically follow stabilization-focused assessments.

Question 13

A wound care nurse has assessed a wound that has partial thickness skin loss and a moist, red wound base. What stage is this wound?

Accepted Answer

Answer reason: Partial-thickness skin loss with a viable, moist, red/pink wound bed is characteristic of epidermal and partial dermal involvement without exposure of fat or deeper structures. This presentation aligns with a shallow open ulcer or ruptured/intact serum-filled blister typical of a stage 2 pressure injury. Stage 1 would have intact skin with nonblanchable erythema, while stages 3–4 involve full-thickness loss with visible adipose, muscle, tendon, or bone.

Question 14

The nurse is caring for a comatose patient and notes their arms are flexed and internally rotated, and their legs are extended and rotated inward. The nurse should document this finding as what type of posturing?

Accepted Answer

Answer reason: Documenting the correct posture type is part of a focused neurologic assessment used to trend deterioration and localize injury. In contrast, decerebrate posturing is characterized by extension and pronation of the arms (rather than flexion), suggesting more caudal brainstem involvement. Prompt recognition supports escalation of care because worsening posturing can indicate rising intracranial pressure or herniation risk.

Question 15

When obtaining orthostatic vital signs, which position should the nurse have the patient assume last?

Accepted Answer

Answer reason: The standard sequence is supine (or lying) first to establish baseline after rest, then seated, and finally standing to evaluate for the greatest venous pooling and drop in blood pressure. Placing standing last also reduces fall risk by allowing staged transitions while monitoring symptoms such as dizziness or syncope. Prone is not part of routine orthostatic measurements and can delay recognition of postural hypotension.

Question 16

When assessing a patient’s peripheral vision, which test is the nurse likely to perform?

Accepted Answer

Answer reason: This directly assesses peripheral vision loss that can occur with retinal disease, glaucoma, or neurologic lesions (e.g., optic tract/occipital pathology). The corneal light reflex and cover test primarily evaluate ocular alignment/strabismus, not visual fields. The six cardinal positions of gaze assess extraocular muscle function and cranial nerves III, IV, and VI rather than peripheral vision.

Question 17

With the patient's eyes closed, the nurse asks the patient to identify a familiar object placed in their hand? What is the nurse assessing?

Accepted Answer

Answer reason: Identifying a familiar object placed in the hand relies on intact tactile perception and higher-level parietal lobe processing (tactile agnosia if impaired). This differs from graphesthesia, which is recognizing numbers/letters traced on the skin, and from barognosis, which is detecting differences in weight. Failure suggests a sensory integration deficit rather than a primary motor-planning problem like apraxia.

Question 18

Where should the nurse place their stethoscope to auscultate a patient's apical pulse?

Accepted Answer

Answer reason: The apical pulse is assessed at the point of maximal impulse, which corresponds to the mitral area of the heart. In adults, this landmark is typically located at the 5th intercostal space along the left midclavicular line. This placement best captures left ventricular activity and is the standard location used when an accurate heart rate is required (e.g., prior to certain cardiac medications). Options describing the left sternal border correspond more to tricuspid/pulmonic areas and are less reliable for measuring the true apical rate. The right midclavicular location is not the normal site for apical pulse auscultation in an adult.

Question 19

When entering the room of a newly admitted patient, the nurse notes the patient is drowsy but is easily awakened when the nurse says the patient’s name in a normal voice. The nurse understands this is an assessment of which of the following?

Accepted Answer

Answer reason: Being drowsy but easily awakened to their name spoken in a normal voice indicates a mildly decreased arousal level without requiring painful stimulus, fitting an LOC assessment. Orientation assesses awareness of person/place/time/situation after arousal, which is not what is being tested here. Cognition and overall mental status are broader domains and are not specifically determined by arousability alone.

Question 20

Which of the following would lead to inaccurately high reading of blood pressure?

Accepted Answer

Answer reason: Crossing the legs can raise systolic (and sometimes diastolic) pressure by compressing vessels and increasing sympathetic tone, producing a falsely elevated reading. By contrast, holding the arm above heart level tends to falsely lower the measured pressure due to hydrostatic effects. Using a cuff that is too large generally underestimates blood pressure rather than overestimating it.

Question 21

A client has a large abdominal incision and is receiving continuous IV opioid analgesics. Which of the following actions should the nurse take first?

Accepted Answer

Answer reason: The nurse should first evaluate respiratory rate, depth, oxygen saturation, level of consciousness, and sedation score to determine safety before any additional analgesic is considered. Interventions like coughing and deep breathing are important postoperatively, but they are secondary if ventilation is compromised. Giving a PRN opioid without reassessment could worsen respiratory depression and lead to rapid clinical deterioration.

Question 22

The nurse is preparing to take a blood pressure on a newly admitted patient. Which of the following is NOT a contraindication for taking a blood pressure?

Accepted Answer

Answer reason: An AV fistula is a dialysis access that can thrombose or be damaged by compression, and an arm with an IV infusion can have inaccurate readings and risk infiltration/occlusion from cuff pressure. After mastectomy (especially with lymph node dissection), cuff compression can worsen lymphedema risk, so the opposite arm is preferred. An internal metal rod in the humerus does not typically interfere with cuff inflation or vascular flow and is not a standard contraindication unless there are specific provider restrictions or acute complications.

Question 23

A nurse is assessing a newly admitted patient with acute psychosis. The nurse should suspect tardive dyskinesia when the patient begins exhibiting which of the following?

Accepted Answer

Answer reason: Orofacial dyskinesias—such as abnormal tongue movements, chewing motions, and lip smacking—are classic early clues that should prompt urgent assessment of antipsychotic exposure and symptom severity. In contrast, fine hand tremor and “pill-rolling” more strongly suggest parkinsonism (a different extrapyramidal effect) rather than tardive dyskinesia. Blurred vision and sexual dysfunction are more consistent with anticholinergic effects and hyperprolactinemia/sexual side effects, respectively, and are not hallmark TD findings.

Question 24

A client with leukemia has neutropenia. Which of the following functions must be frequently assessed?

Accepted Answer

Answer reason: Frequent respiratory assessment helps detect early infection when classic inflammatory signs may be blunted due to low neutrophil response. New crackles, diminished air movement, or focal changes can be the earliest bedside clues prompting urgent evaluation and treatment for febrile neutropenia. In contrast, routine bowel or heart sound checks are less sensitive for early infectious deterioration than monitoring for pulmonary involvement.

Question 25

Which of the following sounds is distinctly heard on auscultation over the abdominal region of an abdominal aortic aneurysm client?

Accepted Answer

Answer reason: Over an abdominal aortic aneurysm, this manifests as an abdominal bruit, often heard around the periumbilical area. Crackles are adventitious lung sounds, dullness is a percussion finding rather than an auscultatory sound, and friction rubs reflect inflamed serosal surfaces (e.g., pleura/pericardium) rather than arterial turbulence. Identifying a bruit supports vascular pathology assessment and helps prompt further evaluation and monitoring for complications.

Question 26

With the patient’s eyes closed, the nurse traces a number on the patient’s hand and asks them to identify it. What is the nurse assessing?

Accepted Answer

Answer reason: Being able to correctly identify the number indicates preserved higher-order tactile discrimination (stereognostic-type sensation). Two-point discrimination instead measures the ability to distinguish two simultaneous touch points, not recognize symbols. Ataxia is a cerebellar motor coordination problem, and orientation is a cognitive assessment unrelated to tactile cortical sensation.

Question 27

A client taking antipsychotic medication requires monitoring for side effects. Which diagnostic test should the nurse prioritize to assess for extrapyramidal symptoms?

Accepted Answer

Answer reason: The AIMS is a standardized bedside screening tool used to detect and trend abnormal involuntary movements over time, supporting early identification and intervention. Serum creatinine and liver function tests monitor renal/hepatic toxicity but do not assess EPS. A complete blood count is important for certain agents (eg, clozapine-related agranulocytosis) but is not the priority measure for EPS detection.

Question 28

A nurse is caring for a postoperative patient who has not voided for 8 hours. The patient reports lower abdominal discomfort and restlessness. Which of the following actions should the nurse take first?

Accepted Answer

Answer reason: The first nursing priority is to objectively assess whether the bladder is distended and quantify retained urine so the next action (prompted voiding vs catheterization per protocol) is appropriate and safe. Increasing oral fluids is slow and does not address an already overfilled bladder, and simply ambulating to the bathroom may delay needed decompression if significant retention is present. The provider is typically notified after assessment confirms retention or if the nurse cannot follow an existing urinary retention protocol.

Question 29

For which time period would the nurse notify the health care provider that the client had no bowel sounds?

Accepted Answer

Answer reason: Standard nursing assessment practice is to listen in each quadrant and, if no sounds are heard, continue auscultation for a full 5 minutes before concluding they are absent. This reduces false alarms from brief physiologic quiet periods and ensures the nurse reports a clinically meaningful abnormal assessment. Shorter time frames (2–4 minutes) do not meet the commonly taught threshold for declaring absent bowel sounds and may lead to premature provider notification.

Question 30

A nurse is assessing a 2-year-old child diagnosed with croup. Which action should the nurse perform first?

Accepted Answer

Answer reason: The nurse must first assess the child's condition to determine severity, especially respiratory status. Vital signs provide critical information about airway compromise and overall stability. Interventions such as medication or provider notification should follow based on assessment findings. Obtaining a throat swab is contraindicated due to the risk of airway obstruction.

Question 31

When a nurse is preparing to measure the temperature of an alert patient admitted to the hospital due to dehydration caused by vomiting and diarrhea, which method is most appropriate?

Accepted Answer

Answer reason: In an alert, cooperative adult, the oral route is a standard, noninvasive method that provides reliable readings without unnecessary exposure or procedural risks. Rectal temperatures are more invasive and are generally avoided in patients with diarrhea due to contamination risk, patient discomfort, and potential mucosal irritation. Axillary measurements are less accurate and are typically reserved for situations where oral/other routes are contraindicated. The radial route is used for pulse assessment, not for measuring body temperature.

Question 32

When assessing for edema, the nurse notes a 2 mm indentation left in the patient's skin after pressing down. How should this be documented?

Accepted Answer

Answer reason: A 2 mm pit corresponds to mild edema, documented as 1+. Higher grades (e.g., 2+ and 4+) indicate progressively deeper pitting (around 4 mm and 8 mm, respectively) with slower rebound, so they do not match a 2 mm finding. Non-pitting edema would not leave a persistent indentation after pressure, making it inconsistent with the assessment finding.

Question 33

The nurse is auscultating a patients lung fields who has severe asthma. Air passing through narrowed bronchioles would produce which of the following breath sounds?

Accepted Answer

Answer reason: In asthma, bronchiolar smooth muscle constriction and mucosal edema reduce airway caliber, making wheezing a classic expiratory finding. Crackles are discontinuous popping sounds from alveoli/small airways reopening, more typical of fluid or atelectasis rather than bronchospasm. Rhonchi are lower-pitched, coarse sounds usually related to secretions in larger airways, and resonance describes a normal percussion note rather than an auscultated breath sound.

Question 34

The nurse is auscultating a patient’s lung fields and hears a low-pitched coarse sound on expiration that has a snoring quality. The nurse should document this finding as which of the following?

Accepted Answer

Answer reason: This description aligns with rhonchi, which often change or clear after coughing or suctioning because the underlying issue is mucus movement. Crackles are discontinuous popping sounds (often inspiratory) from alveolar fluid/reopening rather than a snoring quality. Wheezes are typically higher-pitched, musical sounds from narrowed airways, and a pleural friction rub is a grating sound from inflamed pleural surfaces.

Question 35

The nurse is aware that the following findings would be further evidence of a urethral injury in a male client during rectal examination?

Accepted Answer

Answer reason: Recognizing this finding is clinically important because it supports avoiding urethral instrumentation (e.g., blind Foley insertion) until urethral integrity is assessed. A boggy mass is more consistent with a prostate issue such as prostatitis rather than traumatic urethral disruption. Absent sphincter tone suggests spinal cord/neurologic injury, and a positive Hemoccult indicates gastrointestinal bleeding, neither of which specifically supports urethral injury.

Question 36

Bryce is a child diagnosed with coarctation of aorta. While assessing him, Nurse Zach would expect to find which of the following?

Accepted Answer

Answer reason: This classically produces strong upper-extremity pulses with weak or delayed lower-extremity pulses, so femoral pulses are diminished or absent compared with brachial/radial pulses. The other listed findings are more consistent with cyanotic congenital heart disease (e.g., tetralogy of Fallot), where right-to-left shunting causes cyanosis and "tet" spells. Coarctation is typically an acyanotic lesion unless severe and associated with additional defects, making pulse discrepancies the key assessment finding.

Question 37

For a male client with hyperglycemia, which assessment finding best supports a nursing diagnosis of Deficient Fluid Volume?

Accepted Answer

Answer reason: With volume depletion, the kidneys conserve water, producing more concentrated urine, which is reflected by higher urine osmolality. Distended neck veins indicates fluid volume excess (elevated venous pressure), making it the opposite of the diagnosis. Cool, clammy skin is more consistent with shock/sympathetic response and is less specific for fluid volume deficit in this context than a concentration marker tied to osmotic diuresis.

Question 38

When auscultating the chest of a client with pneumonia, the nurse would expect to hear which of the following sounds over areas of consolidation?

Accepted Answer

Answer reason: This produces bronchial breath sounds in the peripheral lung fields where vesicular sounds should normally be heard, a classic finding with lobar pneumonia. Bronchovesicular sounds are typically normal over the main bronchi (1st–2nd interspaces anteriorly and between scapulae) rather than indicating peripheral consolidation. Vesicular sounds are expected over healthy alveoli and are often diminished or replaced when consolidation is present.

Question 39

Which of the following is the most important physical assessment parameter the nurse would consider when assessing fluid and electrolyte imbalance?

Accepted Answer

Answer reason: Assessing heart rate and rhythm directly evaluates the most immediate, high-risk physiologic consequence of significant fluid/electrolyte shifts. Measures like skin turgor and intake/output are useful indicators of volume status but are less sensitive to acute electrolyte-driven instability and do not directly reflect imminent danger. Because arrhythmias can precede other overt signs and require urgent intervention, cardiac assessment is prioritized. This aligns with nursing assessment focusing on early detection of potentially fatal complications.

Question 40

The nurse is performing an abdominal assessment. Which step should be completed last?

Accepted Answer

Answer reason: The correct order is inspection, auscultation, percussion, then palpation. Palpation can stimulate peristalsis and change the frequency/character of bowel sounds, which would make earlier findings less reliable. Percussion is done after auscultation for the same reason—mechanical stimulation can affect sounds and patient guarding, but palpation is most likely to provoke these changes.

Question 41

The nurse is assessing a patient for pitting edema. The nurse finds the depth of the edema to measure 4mm. How would the nurse document this in the patient's chart?

Accepted Answer

Answer reason: A 4 mm indentation corresponds to moderate pitting, which is graded as 2+. This ensures consistent communication of assessment severity across the care team and helps trend fluid status changes over time. A common distractor is 1+, which aligns with a smaller pit depth (about 2 mm) and would understate the finding.

Question 42

The nurse has an order to check the patient's peripheral vision. Which exam is specific to peripheral vision?

Accepted Answer

Answer reason: The confrontation test specifically assesses peripheral vision by having the client identify objects or finger movement in each quadrant while maintaining central gaze. By contrast, corneal light reflex and the cover test evaluate ocular alignment/strabismus, and six cardinal fields of gaze assesses extraocular muscle function (CN III, IV, VI), not peripheral fields. This makes confrontation the most direct and clinically appropriate exam for an order to check peripheral vision.

Question 43

During an assessment, the nurse notes a clear fluid filled, elevated lesion

Accepted Answer

Answer reason: This matches the finding of a clear fluid-filled, raised lesion under 1 cm. In contrast, a papule is solid (no fluid), a macule is flat (not elevated), and a pustule contains purulent material rather than clear fluid. Accurate lesion terminology supports consistent documentation and appropriate follow-up assessment.

Question 44

A nurse is assessing a two month old infant post-op. Which pain scale should the nurse use for this patient?

Accepted Answer

Answer reason: The FLACC scale (Face, Legs, Activity, Cry, Consolability) is designed for nonverbal children, including infants, and is appropriate for post-operative pain monitoring. Numeric rating scales require cognitive and language skills that a 2-month-old does not have. Visual self-report tools like Oucher and Wong-Baker faces are intended for older children who can understand and choose a face that matches their pain.

Question 45

Newborn presents with deep pink/red coloration on one side of the body while opposite side remains pale or normal, this condition is known as?

Accepted Answer

Answer reason: Harlequin sign is a transient vascular phenomenon in newborns where one side of the body appears flushed while the other remains pale due to immature autonomic regulation.

Question 46

Dehydrated child will have?

Accepted Answer

Answer reason: Dehydration in children presents with classic signs including decreased skin turgor (slow recoil), sunken eyes, and a depressed fontanelle in infants. These are key assessment findings used to determine severity.

Question 47

A nurse is preparing to perform an initial assessment on a newly admitted client. Which action should the nurse take first?

Accepted Answer

Answer reason: The nursing process begins with assessment, which involves collecting subjective and objective data before any planning, implementation, or evaluation can occur. Establishing a complete data set is essential for identifying problems and guiding safe, effective care.

Question 48

The postpartum nurse is assessing a client who delivered a healthy infant by cesarean section for signs and symptoms of superficial venous thrombosis. Which sign should the nurse note if superficial venous thrombosis were present?

Accepted Answer

Answer reason: This directly matches the finding of enlarged, hardened veins on assessment. Paleness or coolness of the calf suggests impaired arterial perfusion rather than a superficial venous problem. Palpable dorsalis pedis pulses indicate intact arterial circulation and do not point toward superficial venous thrombosis.

Question 49

The nurse is assessing a client with Parkinson disease (PD). Which of the following findings would support a diagnosis of PD?

Accepted Answer

Answer reason: A drop in blood pressure with positional change causing dizziness or lightheadedness is therefore a supportive non-motor finding. Nystagmus points more toward vestibular/cerebellar pathology, and swollen, red joints suggests inflammatory arthritis rather than a neurodegenerative disorder. Spontaneous bruising is more consistent with platelet/coagulation problems or medication effects, not a typical PD diagnostic feature.

Question 50

Which assessment finding assists the nurse in confirming inhalation injury?

Accepted Answer

Answer reason: This finding helps confirm smoke or heat exposure affecting the larynx/trachea and signals risk for progressive airway obstruction. Decreased blood pressure is more consistent with hypovolemia/shock (e.g., major burns) rather than a specific indicator of inhalation injury. Nausea and headache are nonspecific and can occur with many conditions; headache may suggest carbon monoxide exposure but does not confirm airway injury as directly as a brassy cough.
