Chapter 58 : Otic Drugs Questions
Question 1 of 5
What teaching by the nurse is important for the safety of the patient who had just received eardrops?
Correct Answer: A
Rationale: Warn the patient that dizziness may occur after application of the eardrops; the patient should remain supine or sitting during instillation and for a few minutes thereafter.
Question 2 of 5
The nurse is teaching a patient about proper administration of eardrops. Which statements are correct? (Select all that apply.)
Correct Answer: C,D,E
Rationale: Remove cerumen before instillation by irrigation, not with cotton-tipped swabs. The drops must be at room temperature; cold drops may cause dizziness or other discomfort. Hold the pinna of the ear up and back when giving eardrops to adults or children older than 3 years of age. A small cotton ball may be inserted gently into the ear canal to keep the drug in place, but do not force or jam it into the ear canal.
Question 3 of 5
A patient has been diagnosed with bacterial otitis externa and will be receiving eardrops. Which of these eardrops are appropriate for this infection? (Select all that apply.)
Correct Answer: A,E
Rationale: Both Floxin Otic and Cipro HC Otic are antibacterial eardrops. Cipro HC also contains a corticosteroid. Both Cortic and Acetasol HC are antifungal products; Debrox (carbamide peroxide) is an earwax emulsifier used to loosen earwax for easier removal.
Question 4 of 5
The nurse is preparing to administer a new order for eardrops. Which is a potential contraindication to the use of many otic preparations?
Correct Answer: B
Rationale: While some antibiotics can be used when an eardrum is perforated, neomycin, polymyxin B, and hydrocortisone otic preparations are contraindicated in patients with a perforated eardrum. Be sure to clarify whether the drug can be given if a perforated eardrum is present. The other options are potential indications for eardrops.
Question 5 of 5
The nurse is administering eardrops that contain a combination of an antibiotic and a corticosteroid. What is the rationale for combining these two drugs in eardrops?
Correct Answer: D
Rationale: Corticosteroids, such as hydrocortisone, are commonly used in combination with otic antibiotics to reduce the inflammation and itching associated with ear infections. Antibiotics do not eliminate fungal infections.
