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
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.
