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:

A) This is the correct answer. A digital rectal exam (DRE) involves the insertion of a gloved, lubricated finger into the rectum to feel the size, shape, and texture of the prostate gland. It helps assess for enlargement and any abnormalities.

B) The prostate-specific antigen (PSA) blood test measures the level of PSA in the blood, which may be elevated in various prostate conditions, including BPH. However, it does not directly assess the size and shape of the prostate gland.

C) Transrectal ultrasound (TRUS) uses sound waves to create images of the prostate gland and is used to assess the prostate's size and identify any abnormalities.

D) Urinalysis is a urine test that evaluates the urine's physical and chemical properties but does not directly assess the size and shape of the prostate gland.

A. Limiting fluid intake in the morning is not likely to be helpful in reducing nighttime awakenings caused by urinary frequency and nocturia.

B. Limiting fluid intake in the afternoon is not likely to be helpful in reducing nighttime awakenings caused by urinary frequency and nocturia.

C. This is the correct answer. Limiting fluid intake in the evening can help reduce the volume of urine produced during the night, thereby decreasing nocturia and nighttime awakenings.

D. Limiting fluid intake at night may cause dehydration and is not recommended. Instead, the client should focus on reducing evening fluid intake to minimize nighttime urine production.
