1. A patient with osteoporosis is prescribed raloxifene (Evista). What is the primary therapeutic action of this medication?

Correct answer: A

Rationale: The correct answer is A. Raloxifene works by decreasing bone resorption and increasing bone density. This helps in preventing further bone loss and reducing the risk of fractures in patients with osteoporosis. Choice B is incorrect because raloxifene does not stimulate the formation of new bone, but rather helps to maintain existing bone mass. Choice C is incorrect as raloxifene does not directly increase calcium absorption in the intestines. Choice D is also incorrect as raloxifene does not increase the excretion of calcium through the kidneys.

2. Which term should the nurse use to document a situation in which cells increase in size and function?

Correct answer: B

Rationale: Hypertrophy is the correct term used to describe the situation in which cells increase in size and function. Atrophy (Choice A) is the opposite, indicating a decrease in cell size. Metaplasia (Choice C) refers to the reversible replacement of one mature cell type by another. Hyperplasia (Choice D) involves an increase in the number of cells, not just an increase in size and function as in hypertrophy.

3. A patient is prescribed raloxifene (Evista) for osteoporosis. What is the primary mechanism of action for this medication?

Correct answer: A

Rationale: Raloxifene decreases bone resorption, which helps to maintain or increase bone density, making it effective in the prevention and treatment of osteoporosis.

4. A patient develops itching and burning of the vaginal vault while taking an anti-infective to treat strep throat. What fungal agent has most likely caused the burning and itching?

Correct answer: B

Rationale: The correct answer is B: Candida albicans. Candida albicans is a common fungal agent responsible for causing vaginal yeast infections characterized by itching and burning. It is known to overgrow in the vagina, especially when the normal vaginal flora is disrupted, such as during antibiotic use. Cryptococcus neoformans is more associated with causing meningitis in immunocompromised individuals, not vaginal symptoms. Aspergillus is more commonly associated with lung infections and allergic reactions, not vaginal infections. Dermatophytes typically cause skin infections like ringworm, not vaginal symptoms.

5. A 67-year-old man is receiving androgen therapy for osteoporosis. What laboratory test should the nurse monitor during this therapy?

Correct answer: A

Rationale: During androgen therapy, monitoring liver function tests is crucial to detect any signs of liver dysfunction. Androgens can potentially impact liver function, making it essential to monitor enzymes such as ALT and AST. While blood glucose levels and cholesterol levels are important parameters to monitor in certain situations, they are not the primary focus during androgen therapy for osteoporosis. Prostate-specific antigen (PSA) monitoring is more relevant in the context of prostate health and cancer screening, not specifically during androgen therapy for osteoporosis.
