Question 1 of 5
A 27-year-old medical student has recurrent sinusitis and takes an over-the-counter agent. Unfortunately, he fell asleep while taking his final examination of the anatomy course. Which of the following agents is most likely to cause this adverse effect?
Correct Answer: D
Rationale: Sinusitis treatment often involves OTC antihistamines. Diphenhydramine , an H1 antihistamine, causes sedation, explaining the student's sleepiness during the exam. Doxycycline , an antibiotic, doesn't sedate. Doxylamine , another sedating antihistamine, is possible but less commonly linked to sinusitis OTC use. Doxazosin , an α-blocker, isn't for sinusitis. Hydroxyzine (E) sedates but is prescription-based. Diphenhydramine's widespread OTC availability and drowsiness side effect fit the scenario, impacting the student's performance.

Question 3 of 5
Which of the following agents is available as a patch for once-daily use and is likely to provide steady drug levels to treat Alzheimer's disease?
Correct Answer: A
Rationale: Rivastigmine, an acetylcholinesterase inhibitor, treats Alzheimer's by increasing acetylcholine, improving cognition. Its transdermal patch delivers steady drug levels daily, minimizing peaks/troughs and reducing GI side effects (e.g., nausea) compared to oral forms, enhancing compliance. Donepezil, memantine, and galantamine are oral, lacking a once-daily patch; donepezil's long half-life mimics steady-state but isn't transdermal. Glatiramer treats MS, not Alzheimer's. Rivastigmine's patch formulation ensures consistent cholinergic enhancement, critical for sustained symptom relief in Alzheimer's, distinguishing it as the optimal choice here.
Question 4 of 5
The client receives estrogen for prostate cancer. He asks the nurse why he is receiving a female hormone. What is the best response by the nurse?
Correct Answer: C
Rationale: Prostate cancer is androgen-dependent, relying on testosterone and other androgens for growth. Estrogen therapy suppresses pituitary secretion of luteinizing hormone, reducing testicular androgen production, effectively starving the cancer. This hormonal manipulation is a standard approach. Choice A inaccurately suggests direct cell death, not estrogen's mechanism. Choice B overstates testosterone elimination; it's reduced, not eradicated. Choice D misattributes nutrient blockade, unrelated to estrogen's action. The nurse's best response (C) clarifies estrogen's role in androgen suppression, addressing the client's confusion with precision and relevance to his treatment.
