There are several types of hearing loss. Which type of hearing loss benefits from the use of a hearing aid?
- A. Sensorineural
- B. Conductive
- C. Genetic
- D. Acquired
Correct Answer: B
Rationale: Diminished hearing results from a conductive loss, sensorineural loss, or both. Clients with a conductive hearing loss benefit more from the use of a hearing aid because the structures that convert sound into energy and facilitate perception of sound in the brain continue to function. Genetic and acquired are not types of hearing loss.

The nurse is teaching a family member how to instill ear drops to the client to remove impacted cerumen. What is important to teach this family member?
- A. Insert the irrigating syringe deeply.
- B. Direct the flow of the ear drops toward the eardrum.
- C. Refrigerate before instillation.
- D. Place the container in warm water before instillation.
Correct Answer: D
Rationale: If irrigation or instillation of liquids is ordered, the liquid should be warmed to body temperature by placing the container in warm water. Cold or hot liquids cause dizziness, and the potential for injury exists if the liquid is hot. The family member should avoid inserting the irrigating syringe too deeply so as not to close off the auditory canal. The family member should direct the flow toward the roof of the canal, rather than the eardrum.
A client comes to the walk-in clinic reporting feeling a 'bug in my ear.' What action should be taken when there is an insect in the ear?
- A. Instillation of mineral oil
- B. Instillation of carbamide peroxide
- C. Instillation of hot water
- D. Use of a small forceps
Correct Answer: A
Rationale: Mineral oil is instilled into the ear to smother an insect. Carbamide peroxide is used to soften dried cerumen, and small forceps are used to remove solid objects. Hot liquids cause dizziness and should not be instilled in the ear.
What kind of otitis media is a pathogen-free fluid behind the tympanic membrane, resulting from irritation associated with respiratory allergies and enlarged adenoids?
- A. Purulent otitis media
- B. Infectious otitis media
- C. Serous otitis media
- D. Sterile otitis media
Correct Answer: C
Rationale: Serous otitis media, a collection of pathogen-free fluid behind the tympanic membrane, results from irritation associated with respiratory allergies and enlarged adenoids. The other options are distractors for this question. Purulent otitis media usually results from the spread of microorganisms from the eustachian tube to the middle ear during upper respiratory infections.
What aspect should the nurse closely monitor for in clients who have been administered salicylates, loop diuretics, quinidine, quinine, or aminoglycosides?
- A. Signs of hypotension
- B. Reduced urinary output
- C. Tinnitus and sensorineural hearing loss
- D. Impaired facial movement
Correct Answer: C
Rationale: It is important that nurses are knowledgeable about the ototoxic effects of certain medications such as salicylates, loop diuretics, quinidine, quinine, and aminoglycosides. Signs and symptoms of ototoxicity include tinnitus and sensorineural hearing loss. Hypotension, reduced urinary output, and impaired facial movement are not signs of ototoxicity.
The nurse is teaching a class on diseases of the ear. What would the nurse teach the class is the most characteristic symptom of otosclerosis?
- A. The client being distressed in the mornings
- B. A progressive, bilateral loss of hearing
- C. A red and swollen ear drum
- D. The client describing a recent upper respiratory infection
Correct Answer: B
Rationale: A progressive, bilateral loss of hearing is the characteristic symptom of otosclerosis. Tinnitus appears as the loss of hearing progresses; it is especially noticeable at night, when surroundings are quiet, and may be quite distressing to the client. The eardrum appears pinkish-orange from structural changes in the middle ear. The client often describes a history of having had a recent upper respiratory infection in case of otitis media, not otosclerosis.
