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: The symptoms suggest possible urinary retention, which could be a result of benign prostatic hyperplasia (BPH) or another obstruction. Palpating the suprapubic area for distention is important to assess for urinary retention and determine if the bladder is full. B. Obtain a urine specimen for culture and sensitivity: Although a urinary tract infection can cause urinary symptoms, the client's presentation is more likely indicative of a physical obstruction such as BPH. A culture might be needed later if infection is suspected. C. Instruct in effective techniques to cleanse the glans penis: Proper hygiene is important, especially in older adult men, but this is not the most relevant action for the symptoms described. The focus should be on assessing for possible urinary retention or obstruction. D. Advise the client to maintain a voiding diary for one week: While a voiding diary may provide useful information for monitoring symptoms over time, the immediate priority is to assess for urinary retention and bladder distention.
