A client with suspected BPH is scheduled for a urodynamic study. The nurse should explain that this test is primarily used to:
Determine the size of the prostate gland
Assess renal function and kidney health
Measure the pressure and flow of urine
Evaluate the bladder's capacity
The Correct Answer is C
A. A urodynamic study is not used to determine the size of the prostate gland. It is primarily focused on assessing bladder and urinary function.
B. A urodynamic study is not used to assess renal function and kidney health. It is a diagnostic test focused on evaluating the lower urinary tract and bladder function.
C. This is the correct answer. A urodynamic study is a diagnostic test used to evaluate the pressure and flow of urine during voiding. It provides valuable information about the lower urinary tract's function, including bladder capacity, detrusor muscle activity, and the presence of any obstructions or abnormalities.
D. A urodynamic study is not used to evaluate the bladder's capacity directly, but it does assess bladder function during voiding.

Correct Answer is D
Explanation
A. This statement is correct. Caffeinated beverages can irritate the bladder and worsen BPH symptoms, so it's best to avoid them.
B. This statement is incorrect. Limiting fluid intake, especially in the evening, can help reduce nighttime urination in clients with BPH.
C. This statement is correct. Pelvic floor exercises, such as Kegel exercises, can help strengthen the pelvic muscles and improve urine flow in BPH.
D. This statement is incorrect. Over-the-counter cold medications containing decongestants can worsen BPH symptoms by constricting blood vessels, including those in the prostate, and can lead to urinary retention.
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.
