Answer to Question 1

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.

Answer to Question 2

ANS: D
Women who have a history of thromboembolic disease must consult with a health care provider before obtaining a prescription for an oral contraceptive. Serious adverse effects include embolisms and thrombus formation, cardiac abnormalities, seizures, and severe depression. STDs, hypothyroidism, and varicose veins do not pose a problem with contraceptive therapy.
