Which finding would indicate a positive response to treatment in a client with BPH?

A positive response to treatment in a client with Benign Prostatic Hyperplasia (BPH) would be indicated by a reduction in urinary retention. BPH often leads to symptoms such as difficulty in urination, increased frequency, urinary retention, and nocturia due to prostate enlargement that obstructs the urinary flow.

When treatment is effective, one of the primary goals is to relieve urinary obstruction and improve overall urinary function. A reduction in urinary retention signifies that the treatment is successfully alleviating the blockage and allowing for better urine flow, thereby enhancing the patient's quality of life.

In contrast, increased urinary frequency, urge incontinence, and persistent nocturia can all indicate that symptoms are either unchanged or worsening, which would not be reflective of a positive response to treatment. Effective management should ideally lead to improved control over urination and a decrease in the urgency or need to urinate frequently.
