A patient diagnosed with benign prostatic hypertrophy asks why tamsulosin (Flomax), an alpha-1 adrenergic blocking agent, has been prescribed. Which explanation by the nurse is most accurate?
a. It inhibits the action of testosterone.
b. It improves sexual function.
c. It reduces the size of the prostate.
d. It increases urinary flow.
ANS: D
Alpha-1 adrenergic blocking agents are used to relax the smooth muscle of the bladder and prostate. Tamsulosin specifically blocks alpha 1 receptors on the prostate gland and certain areas of the bladder neck, causing muscle relaxation and increased urine flow in men with enlarged prostate glands. Adrenergic blocking agents do not affect hormone production, directly affect sexual function, or affect prostate size.
