Dorzolamide drops commonly leave a bitter taste in the mouth.
Correct Answer
True
True. Drug that drains through the nasolacrimal duct reaches the throat, and a bitter taste is one of the most frequent complaints with dorzolamide; closing the eye and pressing on the inner corner can lessen it.

Question 2
Iris darkening caused by latanoprost is usually permanent, even after the drug is stopped.
Correct Answer
True
True. Latanoprost increases melanin in iris cells, and the added brown color is likely permanent, while darkening of the eyelid skin and eyelash changes may fade after stopping.

Question 3
Ciprofloxacin eye drops are used to treat bacterial conjunctivitis and bacterial corneal ulcers.
Correct Answer
True
True. Ciprofloxacin is a fluoroquinolone antibiotic, and its ophthalmic solution is approved for bacterial conjunctivitis and bacterial corneal ulcers. It has no effect on viral or fungal eye infections, which need antiviral or antifungal drugs.
Category: Ocular Anti-infectives
Question 4
Prolonged use of corticosteroid eye drops can raise intraocular pressure, so pressure is checked during therapy.
Correct Answer
True
True. Ocular corticosteroids can reduce aqueous outflow and raise intraocular pressure, which can damage the optic nerve, so pressure is monitored when use continues beyond a short course.
Category: Ocular Anti-inflammatories
Question 5
After a topical anesthetic is instilled, the patient should avoid rubbing the eye until feeling returns.
Correct Answer
True
True. A numbed cornea cannot sense injury, so rubbing can scratch it without the patient noticing; patients are reminded not to touch the eye until sensation returns.

Question 6
Burning on instillation is a common adverse effect of cyclosporine eye emulsion.
Correct Answer
True
True. Ocular burning is the most frequently reported adverse effect of cyclosporine eye emulsion, and patients are told to expect it and report swelling, hives or trouble breathing.
Category: Ocular Anti-inflammatories
Question 7
Only products labeled for ophthalmic use should be placed in the eye, because eye preparations are made sterile.
Correct Answer
True
True. Ophthalmic products are sterile and formulated for the eye, while ear and skin products are not; eye and ear drops are packaged similarly, so labels are read carefully.

Question 8
For a child who keeps the eyes closed, drops can be placed at the inner corner of the closed eye so they flow in when the eye opens.
Correct Answer
True
True. With the child lying down, a drop placed at the inner corner pools there and enters the eye when the child opens it, which avoids forcing the lids apart.

Question 9
Eye ointments blur vision, so patients should avoid driving until vision clears.
Correct Answer
True
True. An ointment film blurs vision for a time after application, so patients avoid driving or operating machinery until it clears, and ointments are often used at bedtime.
Category: Anesthetics and Lubricants
Question 10
Artificial tears that have turned cloudy or changed color should be discarded.
Correct Answer
True
True. Cloudiness or a color change suggests contamination or breakdown of the solution, so the product is thrown away rather than used.
Category: Anesthetics and Lubricants
Question 11
After eye drops are instilled, the patient should blink rapidly to spread the drug.
Correct Answer
False
False. Blinking pumps the drop out of the eye and into the tear duct; the patient should close the eye gently without squeezing.

Question 12
Netarsudil lowers eye pressure mainly by reducing production of aqueous humor.
Correct Answer
False
False. Netarsudil is a rho kinase inhibitor that lowers intraocular pressure mainly by increasing aqueous outflow through the trabecular meshwork.
Category: Glaucoma Drugs
Question 13
Latanoprost commonly causes bradycardia and bronchospasm.
Correct Answer
False
False. Latanoprost has few systemic effects; its common adverse effects are local, such as conjunctival redness, iris and eyelid darkening and eyelash growth, which is why it suits patients with heart or lung disease.
Category: Glaucoma Drugs
Question 14
Ocular NSAIDs such as ketorolac speed healing of the cornea after surgery.
Correct Answer
False
False. Ocular NSAIDs can slow or delay healing, and prolonged use has been linked to keratitis and corneal breakdown in susceptible patients, so new eye pain or vision changes are reported.
Category: Ocular Anti-inflammatories
Question 15
Touching the dropper tip to the eyelid helps steady the bottle and is acceptable.
Correct Answer
False
False. The tip must not touch the eye, lids, lashes or any surface, because contact contaminates the bottle and can injure the eye; resting the hand on the forehead steadies it instead.
Category: Eye Drop Technique
Question 16
Contact lenses can be worn as usual during treatment of bacterial conjunctivitis.
Correct Answer
False
False. Lenses can trap bacteria and irritate the inflamed eye, so patients avoid wearing them during treatment and replace or disinfect them as directed.
Category: Ocular Anti-infectives
Question 17
In the hospital, one bottle of eye drops can be shared among patients who have the same order.
Correct Answer
False
False. Each patient has their own bottle, because a bottle used on one eye can carry organisms to another patient.
Category: Eye Drop Technique
Question 18
Open-angle glaucoma usually causes eye pain early, which reminds patients to use their drops.
Correct Answer
False
False. Open-angle glaucoma is usually painless and causes gradual, unnoticed loss of peripheral vision, which is why nonadherence is common and teaching is important.
Category: Glaucoma Drugs
Question 19
After prolonged use, corticosteroid eye drops can be stopped abruptly without risk.
Correct Answer
False
False. After prolonged use, ocular corticosteroids are tapered as prescribed, because stopping suddenly can let inflammation flare back.
Category: Ocular Anti-inflammatories
Question 20
Antibiotic eye drops cure viral conjunctivitis.
Correct Answer
False
False. Antibiotics act only on bacteria; viral conjunctivitis usually resolves on its own with supportive care and careful hand hygiene to limit spread.
