Question 1

Sensory hair cells are present in?

Accepted Answer

Answer reason: In the cochlea, mechanosensory hair cells (inner and outer hair cells) in the organ of Corti transduce vibrations of the basilar membrane into electrical signals carried by the auditory nerve. Skin contains various mechanoreceptors (e.g., Meissner and Pacinian corpuscles) but not cochlear-type sensory hair cells. The retina uses photoreceptors (rods and cones), and the nose primarily uses olfactory receptor neurons rather than hair cells.
Category reason: This is a foundational structure-function question about where auditory sensory hair cells are located within the ear, which fits ENT anatomy/physiology rather than nursing care decision-making.

Question 2

Age-related hearing Loss is known as ?

Accepted Answer

Answer reason: The correct choice specifically names this physiologic aging process of the auditory system. Otosclerosis more typically causes progressive conductive hearing loss from stapes fixation, and otitis media causes inflammatory conductive loss rather than age-related degeneration. Presbyopia refers to age-related loss of near vision, not hearing.

Question 3

What are symptoms of ear infection?

Accepted Answer

Answer reason: Conductive hearing difficulty and fever can occur, especially with acute otitis media. Otorrhea (fluid drainage) can be seen with otitis externa or tympanic membrane perforation, and dizziness/vertigo may occur when inflammation affects vestibular function. A sense of ear fullness or congestion is also typical due to Eustachian tube dysfunction and middle-ear effusion, making the combined option the best choice.

Question 4

Antroscopy is a visualization of the?

Accepted Answer

Answer reason: The suffix “-scopy” indicates visualization, and “antro-” in ENT commonly denotes the maxillary antrum rather than the stomach or bones. This procedure is used to inspect and manage pathology within the maxillary sinus (e.g., chronic sinusitis, polyps, drainage issues). In contrast, stomach visualization would be described by “gastroscopy,” making that option a classic distractor based on prefix confusion.

Question 5

A client suffering from presbycusis has the most difficulty hearing which of the following sounds?

Accepted Answer

Answer reason: Presbycusis is age-related sensorineural hearing loss that typically affects high-frequency sounds first due to degeneration of cochlear hair cells. High-pitched voices (often women’s and children’s voices) and consonant sounds are therefore harder to detect and discriminate, especially in normal conversation. Lower-frequency, louder sounds (e.g., thunder or engine noise) are generally perceived better than high-frequency speech components. A common trap is choosing a noisy environment (like a post office), but the key feature tested is frequency (high pitch) rather than background noise.

Question 6

Nose infection is called?

Accepted Answer

Answer reason: The suffix “-itis” denotes inflammation, and “rhin-” refers to the nose, making this the precise term for nose inflammation/infection. By contrast, otitis involves the ear, nephritis involves the kidney, and gastritis involves the stomach. Therefore the only option anatomically and terminologically consistent with a nose infection is the one using the rhin- root.

Question 7

Ear wax is medically called --?

Accepted Answer

Answer reason: The accepted medical term for this protective substance is cerumen. Its role includes trapping debris, providing lubrication, and contributing to an acidic, antimicrobial environment. The other options refer to general structural proteins or mucus components rather than the specific ear canal secretion.

Question 8

Bilateral progressive hearing loss in a 27-year-old female was first noticed 2 years ago when she was pregnant with her second child. Which illness is most likely the cause of the client’s progressive hearing loss?

Accepted Answer

Answer reason: Progressive conductive hearing loss in a young adult woman that is noticed or worsens during pregnancy strongly suggests stapes fixation from otosclerosis, which can be hormonally influenced and often presents bilaterally. This disorder causes abnormal bone remodeling around the oval window, gradually reducing sound transmission. Acoustic neuroma typically causes unilateral sensorineural loss with tinnitus/imbalance rather than bilateral pregnancy-associated progression. Cholesteatoma and serous otitis media are more associated with chronic ear disease or effusions and do not classically show this pregnancy-linked, slowly progressive bilateral pattern.

Question 9

The client receives a prescription for sodium fluoride for otosclerosis and asks the nurse, “What will this medication do for my ears?” Which response by the nurse is correct?

Accepted Answer

Answer reason:  Otosclerosis involves abnormal bone remodeling around the stapes/otic capsule leading to progressive conductive hearing loss. Sodium fluoride is used to slow the active otosclerotic process by inhibiting bone resorption and promoting mineralization, helping stabilize progression. The histamine/fluid-focused choices describe allergic or effusion mechanisms, not otosclerosis pathophysiology. Options suggesting increased breakdown/softening contradict the therapeutic goal of reducing abnormal remodeling and hardening/mineralization.

Question 10

Inflammation of throat is called—?

Accepted Answer

Answer reason: The “pharynx” corresponds to the throat, so inflammation of the throat is termed pharyngitis. By contrast, gastritis refers to stomach inflammation, glossitis to tongue inflammation, and laryngitis to inflammation of the larynx (voice box) rather than the throat/pharynx. Therefore the term that best matches “inflammation of throat” is the pharyngeal inflammation term.

Question 11

During the examination of ear in children the pinna need to hold in ... direction?

Accepted Answer

Answer reason: This alignment improves visualization of the tympanic membrane and reduces discomfort during otoscopic insertion. Pulling up and back is the adult technique and would leave the pediatric canal more curved, limiting the view. A purely backward pull is usually insufficient to adequately straighten the canal in children.

Question 12

Which of the following is responsible for producing earwax?

Accepted Answer

Answer reason: These glands are modified apocrine-type glands located in the cartilaginous portion of the external ear canal. Their secretion helps trap debris, inhibits microbial growth, and provides lubrication and water resistance to the canal skin. General sweat glands and typical apocrine glands elsewhere do not specifically generate cerumen as a named product in the ear canal.

Question 13

A nurse is assessing an older adult who reports difficulty hearing during conversations, especially in noisy environments. Which of the following findings is most consistent with presbycusis?

Accepted Answer

Answer reason: Presbycusis is age-related sensorineural hearing loss caused by degeneration of cochlear hair cells, classically starting at higher frequencies. This leads to difficulty understanding speech, particularly in environments with background noise where high-frequency consonants are harder to discriminate. Sudden unilateral loss suggests an acute pathology (e.g., sudden sensorineural loss) rather than chronic age-related change. Pain/drainage or aural fullness more strongly indicates external/middle ear disease (e.g., otitis, cerumen, eustachian tube dysfunction) instead of presbycusis.

Question 14

Which examination is used to assess a patient’s hearing via air conduction vs. bone conduction?

Accepted Answer

Answer reason: This test uses a tuning fork to measure whether air conduction is heard longer than bone conduction, which is the normal relationship. A reversal (bone conduction longer than air conduction) supports conductive hearing loss. In contrast, Weber primarily evaluates lateralization between ears rather than directly comparing conduction pathways, and Romberg assesses proprioception/balance rather than hearing.

Question 15

Hearing organ is —?

Accepted Answer

Answer reason: The cochlea houses the organ of Corti, where movement of the basilar membrane bends hair cell stereocilia to generate action potentials transmitted via the vestibulocochlear nerve. Retina and cornea are visual structures of the eye, not involved in auditory transduction. Nephron is the kidney’s functional unit for filtration and urine formation, unrelated to hearing.

Question 16

Ringing sound the ear is known at —?

Accepted Answer

Answer reason: g., noise exposure, age-related hearing loss, ototoxic drugs). This matches the stem’s description of a “ringing sound” in the ear. Vertigo refers to a false sensation of spinning related to vestibular dysfunction rather than an auditory phantom sound. Myopia is a refractive eye disorder, and miosis is pupillary constriction, making them anatomically and clinically unrelated.

Question 17

Inflammation of the ear drum is called —?

Accepted Answer

Answer reason: Inflammation of the tympanic membrane (eardrum) is termed myringitis, often seen with infectious or traumatic irritation of the membrane. Otitis externa refers to inflammation/infection of the external auditory canal, not the eardrum itself. Otalgia is a symptom (ear pain) rather than a diagnosis, and otosclerosis is abnormal bony remodeling of the stapes/otic capsule causing conductive hearing loss rather than inflammation.

Question 18

Tinnitus means ringing in —?

Accepted Answer

Answer reason: It most commonly arises from dysfunction in the auditory system, including the cochlea, auditory nerve, or central auditory pathways. The stem specifically asks where the “ringing” is perceived, which aligns with the classic definition as a symptom related to hearing. Other listed body parts are not associated with the hallmark clinical description of tinnitus.

Question 19

The nurse is documenting a normal finding after assessment of a patient’s tympanic membrane. Which of the following is appropriate documentation?

Accepted Answer

Answer reason: It should be intact and lie in a neutral position without bulging, which would suggest middle-ear effusion or acute otitis media. A pink or erythematous membrane can occur with infection, fever, or crying but is not the classic normal baseline description. “China white” is more consistent with scarring (tympanosclerosis) or abnormal opacity rather than a normal finding.

Question 20

Nurse Veronica is teaching a group of parents about otitis media. When discussing why children are predisposed to this disorder, the nurse should mention the significance of which anatomical feature?

Accepted Answer

Answer reason: This anatomy facilitates reflux of nasopharyngeal secretions and pathogens into the middle ear, especially during upper respiratory infections. Obstruction from adenoidal tissue and mucosal edema further promotes negative middle-ear pressure and fluid accumulation, creating an ideal environment for infection. In contrast, the external ear canal is primarily involved in otitis externa rather than middle-ear infections.

Question 21

A female client is admitted to the facility for investigation of balance and coordination problems, including possible Ménière’s disease. When assessing this client, the nurse expects to note?

Accepted Answer

Answer reason: Ménière’s disease is an inner ear (endolymphatic) disorder classically defined by the triad of episodic vertigo, tinnitus, and fluctuating sensorineural hearing loss due to labyrinthine dysfunction. This combination directly reflects vestibular involvement (vertigo) plus cochlear involvement (tinnitus and hearing loss). Nystagmus and nausea/vomiting can occur during acute vertigo spells, but they are not the defining set expected for Ménière’s compared with the classic triad. Ear pain and fever suggest otitis or another infectious/inflammatory process rather than Ménière’s.

Question 22

Mass of bacteria that grows on surfaces of teeth is called?

Accepted Answer

Answer reason: It forms especially at the gingival margin and in areas that are difficult to clean, and it is the key etiologic factor in dental caries and gingivitis/periodontitis. In contrast, a stain is discoloration on enamel and is not necessarily bacterial mass, and saliva is a fluid secretion rather than an adherent bacterial community. Therefore the term for a mass of bacteria growing on teeth is the adherent biofilm.

Question 23

Commonest site of nosebleed is —?

Accepted Answer

Answer reason: This region is exposed to drying, minor trauma (e.g., nose picking), and inflammation, making it the most frequent bleeding source. Posterior sites (e.g., turbinates/posterior septal branches) are less common but tend to cause heavier bleeding. Therefore the typical, commonest site is the anterior septal Little’s area.

Question 24

A client diagnosed with conductive hearing loss asks the nurse to explain the cause of the hearing problem. The nurse plans to explain to the client that this condition is caused by which problem?

Accepted Answer

Answer reason: g., cerumen, otitis media with effusion, tympanic membrane perforation, ossicular fixation). This directly matches the concept of an obstruction or interruption in transmission of sound waves. By contrast, defects in the cochlea, CN VIII, or central auditory pathways produce sensorineural (or central) hearing loss, where sound is conducted normally but transduction or neural processing is impaired. Clinically, conductive loss often improves with increased volume and shows air-bone gaps on audiometry, consistent with a transmission problem.
