A nurse is caring for a client with BPH who has been prescribed an alpha-blocker. The nurse should anticipate that this medication will primarily work by:

Reducing the size of the prostate

Relaxing the smooth muscles of the bladder neck and prostate

Inhibiting the production of dihydrotestosterone (DHT)

Enhancing urine production by the kidneys

Answer and Explanation

The Correct Answer is B

A. Alpha-blockers do not directly reduce the size of the prostate gland. They work by relaxing the smooth muscles of the bladder neck and prostate, improving urinary flow and reducing obstructive voiding symptoms.

B. This is the correct answer. Alpha-blockers are commonly prescribed for BPH to relax the smooth muscles of the bladder neck and prostate, relieving the obstruction and improving urine flow.

C. Inhibiting the production of dihydrotestosterone (DHT) is the mechanism of action of 5-alpha reductase inhibitors, not alpha-blockers. DHT plays a role in prostate enlargement, and inhibiting its production can reduce the size of the prostate over time.

D. Alpha-blockers do not enhance urine production by the kidneys. They primarily focus on relaxing the smooth muscles to improve urinary flow.

Correct Answer is B

Explanation

B. This is the correct answer. 5-alpha reductase inhibitors work by blocking the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT). DHT is involved in the growth of the prostate gland, and reducing its levels can help shrink the prostate and improve urinary flow in BPH.

C. Inhibiting bacterial growth in the prostate gland is the action of antibiotics, not 5-alpha reductase inhibitors.

D. Contracting the prostate gland is not a desired effect in BPH management.
