An older adult male client arrives at the clinic reporting that his bladder always feels full. The client also reports a weak urine flow, frequent dribbling after voiding, and increasing nocturia with difficulty initiating the urine stream. Which action should the nurse implement?

A. Palpate the client's suprapubic area for distention: Palpating for bladder distention helps determine if urinary retention is present, which is common in older men with possible benign prostatic hyperplasia (BPH). Assessing retention is a priority because unresolved urinary obstruction can lead to hydronephrosis or kidney damage. B. Instruct in effective techniques to cleanse the glans penis: Proper hygiene is important for preventing infection, especially in uncircumcised males, but it does not address the client’s primary problem of urinary retention and obstructive symptoms. C. Obtain a urine specimen for culture and sensitivity: While urinary tract infections can occur in clients with urinary retention, the presenting symptoms here are more indicative of obstruction due to prostate enlargement. A culture may be ordered later, but not the first step. D. Advise the client to maintain a voiding diary for one week: A voiding diary provides helpful long-term information about urinary patterns, but it does not address the acute issue of a bladder that may be distended and retaining urine.
