A nurse is reinforcing teaching with a client who has benign prostatic hypertrophy and has a new prescription for finasteride. Which of the following information should the nurse include in the teaching?
Decreased libido is an adverse effect of the medication.
Prostate-specific antigen (PSA) levels will increase while taking this medication.
Avoid taking the medication with grapefruit juice.
Expect to experience a response from the medication in 1 week.
The Correct Answer is A
A. Decreased libido is a potential adverse effect of finasteride due to its action on reducing dihydrotestosterone levels.
B. Prostate-specific antigen (PSA) levels typically decrease while taking finasteride, not increase. It's important for the nurse to educate the client about the potential impact of finasteride on PSA levels and the interpretation of PSA tests.
C. Avoiding grapefruit juice is not specifically relevant to the use of finasteride. Grapefruit juice can interact with certain medications by affecting their metabolism, but this is not a concern with finasteride.
D. The effects of finasteride on BPH symptoms may take several months to become noticeable.

Correct Answer is C
Explanation
A. There's no documented interaction between cefuroxime and sildenafil. Cefuroxime is an antibiotic, and there are no known significant interactions with sildenafil.
B. There's no documented interaction between metformin and sildenafil. Metformin, an antidiabetic medication, does not interact significantly with sildenafil.
C. Both sildenafil and isosorbide are vasodilators, and concomitant use can result in severe hypotension due to additive effects on blood pressure lowering. Therefore, their combination is contraindicated.
D. Naproxen, a nonsteroidal anti-inflammatory drug (NSAID), does not have a significant interaction with sildenafil. They can be safely used together in most cases, although caution may be needed in individuals with cardiovascular risk factors.
Correct Answer is A
Explanation
A. Lithium can cause hypothyroidism and goiter as adverse effects. Therefore, monitoring of thyroid function and physical examination for thyroid enlargement is necessary during lithium therapy.
B. Constipation is not a typical adverse effect of lithium carbonate. It's more commonly associated with side effects such as nausea, diarrhea, or polyuria.
C. Hyporeflexia is not commonly associated with lithium carbonate use. Lithium more commonly affects the central nervous system, leading to symptoms such as tremors, confusion, and seizures in cases of toxicity.
D. Lithium is more commonly associated with the opposite effect, lowering blood pressure rather than elevating it. It's known to have effects on sodium transport in renal tubules, leading to increased water retention and possibly hypotension.
