What common symptom indicates a high risk for cystitis in a client with BPH?

A feeling of fullness after voiding is indicative of urinary retention, which is a common complication in clients with benign prostatic hyperplasia (BPH). In BPH, the enlargement of the prostate can obstruct urine flow, leading to incomplete bladder emptying. When a client feels a sense of fullness even after attempting to void, it suggests that there may still be residual urine in the bladder, increasing the risk of urinary tract infections such as cystitis. Cystitis is inflammation of the bladder, often caused by infections, and the presence of residual urine provides a favorable environment for bacteria to grow, raising the likelihood of cystitis.

While the other symptoms listed are also relevant to urinary health, they do not specifically indicate the same risk factors associated with cystitis in the context of BPH. Severe pain during urination might be more reflective of an acute infection rather than a direct symptom of BPH leading to cystitis. Nocturnal enuresis may be seen as a result of prostate enlargement but does not directly correlate with an increased risk for cystitis. Difficulty obtaining an erection is associated with the complications of BPH but does not indicate urinary retention or an increased risk for cystitis either. Thus, the feeling of fullness after voiding stands out
