Chapter 43 Questions
Question 1 of 5
What aspect should the nurse closely monitor for in clients who have been administered salicylates, loop diuretics, quinidine, quinine, or aminoglycosides?
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.
Question 2 of 5
What kind of otitis media is a pathogen-free fluid behind the tympanic membrane, resulting from irritation associated with respiratory allergies and enlarged adenoids?
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.
Question 3 of 5
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?
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.
Question 4 of 5
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?
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.
Question 5 of 5
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?
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.
