Question 1
Glaucoma is an optical disorder characterized by increased intraocular pressure (IOP). What causes
increased IOP?
Correct response:
Impaired drainage of aqueous humor
Explanation:
Normally, production and drainage of aqueous humor are approximately equal, and normal intraocular
pressure (IOP) is maintained. Impaired drainage of aqueous humor causes increased IOP.
Question 2
Which of the following can a nurse recommend to a patient to aid in removing cerumen? (Choose one)
Correct response:
Carbamide peroxide
Explanation:
The nurse can recommend carbamide peroxide to aid in the removal of cerumen from the ear canal.
Question 3
If a nurse needs to administer otic preparations in both of the patient's ears, how long should the nurse
wait to place drops in the second ear? (Choose one)
Correct response:
At least 5 minutes
Explanation:
If medication is needed in the other ear, it is best to wait at least 5 minutes after instillation of the first ear
drops before administering drops to the other ear.
Question 4
A patient is prescribed ophthalmic corticosteroids. What eye disorder may result from long-term use of
ophthalmic corticosteroids?
Correct response:
Glaucoma
Explanation:
Long-term use of corticosteroid ophthalmic agents may result in glaucoma, increased IOP, optic nerve
damage, defects in visual acuity, and fields of vision, cataracts, and secondary ocular infections.
Question 5
A nurse is administering multiple eye drops to a patient. How long should the nurse wait between the
instillation of drops of medication in the eye?
Correct response:
5 minutes
Explanation:
When multiple eye drops are required, there should be an interval of 5–10 minutes between drops. The
drops should not be as close as 1 minute. The drops will not need to be separated by 15–20 minutes.
Question 6
, A patient has been treated several times for a recurring ear infection with ofloxacin. The nurse instructs
the patient to look for side effects from the prolonged use of the antibiotic and informs the patient that this
is known as which of the following?
Correct response:
superinfection
Explanation:
Prolonged use of otic preparations containing an antibiotic may result in a superinfection (an overgrowth
of bacterial or fungal microorganisms not affected by the antibiotic being administered).
Question 7
The nurse identifies which of the following as the correct method to instill ear drops in the adult patient?
Correct response:
The nurse pulls the pinna of the ear up and back.
Explanation:
When instilling ear drops for an adult, the nurse turns the patient's head toward the unaffected side and
pulls the pinna up and back.
Question 8
A nursing student states, "when instilling ear drops in an adult patient you should straighten the ear canal
by pulling the pinna up and back and then insert the dropper into the ear canal." Does this demonstrate an
understanding of the correct method of instilling ear drops?
Correct response:
False
Explanation:
When administering ear drops to the adult, the nurse pulls the pinna up and back but never inserts the
dropper or applicator tip into the ear canal.
Question 9
When instilling ear drops, the nurse informs the patient that to facilitate penetration of the drug into the
ear canal, the patient should lie on the untreated side for how many minutes after receiving the drops?
Correct response:
5 minutes
Explanation:
The patient is kept lying on the untreated side after the medication is instilled for approximately 5 minutes
to facilitate penetration of the drops into the ear canal.
Question 10
An elderly patient comes to the clinic and informs the nurse that he feels as if his ear is clogged. He states
that he frequently has to have his ears irrigated to get out the wax. He asks the nurse what causes this wax
build-up. What is the nurse's best response?
Correct response:
Modified sweat glands in the ear canal
Explanation:
Cerumen, a natural product of the ear, is produced by modified sweat glands in the ear canal. Sometimes
too much wax is produced, particularly in the elderly. It is found to be thicker in the elderly who should
frequently be assessed for the build-up of cerumen, which can cause hearing loss.
