Correct Answer is A

Explanation

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.

A. Postpartum infection B. Hypertension C. Postpartum hemorrhage D. Thromboembolic events

Correct Answer is C

Explanation

A. Methylergonovine is not indicated for preventing postpartum infections. Its primary action is on uterine smooth muscle to induce contractions, rather than having antimicrobial properties.
B. While methylergonovine can cause hypertension as a side effect, it's not used to prevent hypertension. It is used primarily to prevent or treat postpartum hemorrhage by promoting uterine contraction.
C. Methylergonovine is a uterotonic medication used to prevent or treat postpartum hemorrhage by causing uterine contractions, thereby reducing the risk of excessive bleeding after childbirth.
D. Methylergonovine does not prevent thromboembolic events; its mechanism of action primarily involves stimulation of uterine smooth muscle contraction rather than affecting blood coagulation.
