A client with benign prostatic hyperplasia (BPH) is prescribed tamsulosin. Which statement by the client indicates correct understanding of how this medication will help relieve symptoms?

Rationale: A. "This medication will relax smooth muscle to improve urine flow.": Tamsulosin is an alpha-1 adrenergic blocker that selectively relaxes smooth muscle in the prostate and bladder neck. This relaxation decreases urethral resistance, allowing urine to flow more easily and relieving lower urinary tract symptoms associated with BPH, such as hesitancy and weak stream. B. "This medication will reduce inflammation in my urinary tract.": Tamsulosin does not have anti-inflammatory properties. It addresses urinary obstruction by relaxing smooth muscle, not by reducing inflammation. C. "This medication will shrink my prostate over time.": Prostate shrinkage is achieved with 5-alpha-reductase inhibitors (e.g., finasteride), not tamsulosin. Tamsulosin improves symptoms without changing prostate size. D. "This medication will increase bladder contractions to help me void.": Tamsulosin does not stimulate detrusor muscle contractions. Its effect is on the smooth muscle of the prostate and bladder neck to reduce resistance, not to increase bladder contractility.
