Which client statement indicates that teaching about finasteride (Proscar) has been effective?
1. "It reduces the inflammation and swelling associated with my prostatitis."
2. "It interferes with my circulating testosterone and causes my prostate to shrink so I can urinate again."
3. "It relaxes the smooth muscle in my urethra to facilitate the outflow of urine."
4. "It kills prostate cells that could lead to cancer."
Correct Answer: 2
Rationale 1: This statement does not indicate teaching has been effective.
Rationale 2: Finasteride (Proscar) works by inhibiting the enzyme responsible for converting testosterone to one of its metabolites, 5-alpha dihydrotestosterone, which causes proliferation of prostate cells and promotes enlargement of the gland. Finasteride promotes regression of prostate epithelial tissue and decreases mechanical obstruction of the urethra.
Rationale 3: This statement does not indicate teaching has been effective.
Rationale 4: This statement does not indicate teaching has been effective.
Global Rationale: Finasteride (Proscar) works by inhibiting the enzyme responsible for converting testosterone to one of its metabolites, 5-alpha dihydrotestosterone, which causes proliferation of prostate cells and promotes enlargement of the gland. Finasteride promotes regression of prostate epithelial tissue and decreases mechanical obstruction of the urethra. It does not reduce inflammation, relax smooth muscle, or kill prostate cells.
