Atenolol, but not prazosin, may decrease heart rate (choice A). Prazosin, but not atenolol, may increase cardiac output, a compensatory effect (choice B). Prazosin may increase renin output (a compensatory response), but P blockers inhibit its release by the kidney (choice C). By reducing blood pressure, both may increase central sympathetic outflow (a compensa tory response). Beta blockers do not cause orthostatic hypo tension. The answer is D.
