Question 1 of 5
A 55-year-old man is concerned about hair loss. The nurse expects that the patient’s baldness may be treated with which drug?
Correct Answer: D
Rationale: Finasteride is an FDA-approved medication for male pattern baldness (androgenetic alopecia). It works by inhibiting the conversion of testosterone to dihydrotestosterone, which is responsible for hair follicle miniaturization. Dexamethasone (A), para-aminobenzoic acid (B), and mupirocin (C) are not used to treat hair loss.
Question 2 of 5
A 31-year-old woman is planning to take a 7-day cruise to the Caribbean islands. She has never been on a ship before and fears developing motion sickness. She purchases scopolamine transdermal patch. When is the best time for her to place the patch to maximize drug efficacy?
Correct Answer: D
Rationale: Scopolamine prevents motion sickness via anticholinergic action. Applying prior to symptoms -ensures prophylaxis. After nausea (A, B) or vomiting is too late. Memory loss is a side effect, not timing. Preemptive use maximizes efficacy for her cruise.
Question 3 of 5
All are specialized transports. except:
Correct Answer: D
Rationale: Simple diffusion is a passive transport process that does not require specialized transport proteins or energy expenditure. It involves the movement of molecules from an area of higher concentration to an area of lower concentration without the aid of a protein channel or carrier. In contrast, active transport, facilitated diffusion, and pinocytosis are specialized transports that utilize specific proteins and mechanisms to help move molecules across cell membranes. Active transport requires energy to move molecules against their concentration gradient, facilitated diffusion involves the use of specific protein channels or carriers to facilitate movement, and pinocytosis is a form of endocytosis where cells engulf fluid droplets.
Question 4 of 5
What patient history would the nurse recognize as a contraindication for beginning Niacin therapy?
Correct Answer: B
Rationale: Gout is a metabolic disorder characterized by elevated levels of uric acid in the blood, which can be exacerbated by niacin therapy. Niacin can increase uric acid levels, potentially leading to gout flare-ups in patients with a history of gout. Therefore, a history of gout would be recognized as a contraindication for beginning Niacin therapy.
