Answer 1

321. The correct option is D. Alpha inhibitors .

Alpha blockers lower blood pressure by keeping the hormone norepinephrine from tightening the muscles in the walls of smaller arteries and veins. As a result, the vessels remain open and relaxed. This improves blood flow and lowers blood pressure.

322. The correct option is A.

Immediate reduction in BP indicated

Reduce mean arterial pressure (MAP) by 10 - 20% over 60 minutes, then 5 - 15% over next 23 hours

Reduce DBP by 10 - 15% or < 110 mmHg over 30 - 60 minutes

323. The correct option is C.

Restoration of intravascular volume with intravenous (IV) saline can prevent precipitous falls in BP when antihypertensive agents are started. After the patient stabilizes, the BP can be lowered about 10% per hour to 160/100-110 mm Hg.

324. The correct option is D.

Normal saline . Restoration of intravascular volume with intravenous (IV) saline can prevent precipitous falls in BP when antihypertensive agents are started.
