,NR 293 Sensory Perception and Pharmacology Comprehensive Exam 2026/2027 UPDATE
1. A patient with chronic open-angle glaucoma is prescribed Timolol ophthalmic drops. Which
assessment finding is most critical for the nurse to report before administration?
A. Resting heart rate of 48 beats per minute
B. History of seasonal allergies
C. Intraocular pressure of 24 mmHg
D. Occasional blurred vision after administration
Answer: A
Rationale: Timolol is a non-selective beta-blocker that can be absorbed systemically,
potentially leading to bradycardia and bronchospasm. A heart rate of 48 is critically low
and requires intervention.
2. When administering Latanoprost (Xalatan) to a patient, the nurse should include which
specific teaching point regarding cosmetic changes?
A. The sclera will develop a yellowish tint.
B. Eyelashes will likely become thinner and shorter over time.
C. The medication may cause permanent darkening of the iris color.
D. Facial hair growth may increase at the site of administration.
, Answer: C
Rationale: Prostaglandin agonists like Latanoprost are known to cause permanent changes
in iris pigmentation, turning light-colored eyes to brown.
3. Which mechanism of action describes how Pilocarpine effectively treats glaucoma?
A. It increases the production of aqueous humor to maintain pressure.
B. It inhibits the enzyme carbonic anhydrase in the ciliary body.
C. It relaxes the ciliary muscle to decrease outflow resistance.
D. It causes miosis, which opens the trabecular meshwork to increase drainage.
Answer: D
Rationale: Pilocarpine is a direct-acting cholinergic agonist that causes miosis (pupillary
constriction). This action pulls the iris away from the filtration angle, facilitating aqueous
humor drainage.
4. A patient is prescribed Acetazolamide for acute glaucoma. The nurse should assess for an
allergy to which class of drugs before administration?
A. Sulfonamides
B. Cephalosporins
C. Penicillins
D. Tetracyclines
Answer: A
