A client with BPH is prescribed a 5-alpha reductase inhibitor. The nurse should instruct the client that this medication works by:
Relaxing the smooth muscles in the bladder neck
Blocking the conversion of testosterone to dihydrotestosterone (DHT)
Inhibiting bacterial growth in the prostate gland
Contracting the prostate gland
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.
