Try Naxlex NCLEX-RN (Free-Trial)

A client with BPH is prescribed a 5-alpha reductase inhibitor. The nurse should instruct the client that this medication works by:

A.

Relaxing the smooth muscles in the bladder neck

B.

Blocking the conversion of testosterone to dihydrotestosterone (DHT)

C.

Inhibiting bacterial growth in the prostate gland

D.

Contracting the prostate gland

Answer and Explanation

The Correct Answer is B

A. Relaxing the smooth muscles in the bladder neck is the action of alpha-blockers, not 5-alpha reductase inhibitors.

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.

Correct Answer is B

Explanation

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.

Questions

Correct Answer is C

Explanation

A. Increasing calcium intake is not specifically indicated for managing urinary frequency and urgency in clients with BPH.

B. Limiting fluid intake, especially in the evening, may help reduce nighttime urination, but it is not advisable to restrict fluids excessively, as dehydration can lead to other health problems.

C. This is the correct answer. Caffeine and alcohol are diuretics that can increase urine production and exacerbate urinary frequency and urgency in clients with BPH. Recommending the avoidance of these substances may help alleviate symptoms.

D. Eating a high-protein diet is not specifically indicated for managing urinary frequency and urgency in clients with BPH.
