Answer to Question 1

B
Feedback:
Saw palmetto is an herbal therapy that has been used very successfully for the relief of symptoms associated with benign prostatic hyperplasia (BPH). Patients with BPH should be cautioned not to combine saw palmetto with finasteride because serious toxicity can occur. There is no contraindication in the use of tamsulosin, alfuzosin, and terazosin, which are alpha-adrenergic blockers. Finasteride is a testosterone blocking agent.

Answer to Question 2

A
Feedback:
Release of ADH causes the kidney to retain water and increase blood volume. Increasing blood volume increases blood pressure.
