Chapter 58 Questions
Question 1 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 2 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.
Question 3 of 5
The nurse is teaching a patient's wife about administering eardrops to her husband. The nurse will use which technique when demonstrating the skill?
Correct Answer: B
Rationale: Hold the pinna of the ear up and back when giving eardrops to adults or children older than 3 years of age.
Question 4 of 5
When reviewing a patient's medical record, the nurse notes an order for carbamide peroxide eardrops. Based on this information, the nurse interprets that these eardrops are being used for which purpose?
Correct Answer: C
Rationale: Wax emulsifiers such as carbamide peroxide work to loosen the cerumen for easier removal.
Question 5 of 5
The nurse is preparing to give an earwax emulsifier to a patient and will assess the patient for which contraindication before administering the drops?
Correct Answer: B
Rationale: Earwax emulsifiers are indicated for excessive earwax in the outer ear canal and are not to be used without prescription when ear drainage, tympanic membrane rupture, or significant pain or other irritation is present. Cerumen impaction may cause partial deafness in the affected ear.
