In hypertensive emergency management, MAP should be reduced by no more than 25% in 24-48 hours.

In hypertensive emergency management, MAP should be reduced by no more than 25% in 24-48 hours.

• A. False
• B. True
• C. 30% in 12 hours
• D. 60% in 24 hours

Answer: (B)

Controlled, gradual reduction of blood pressure is essential in a hypertensive emergency to prevent end-organ ischemia while preserving adequate organ perfusion. The aim is to lower mean arterial pressure by about 20-25% quickly, then continue lowering toward a target such as 160/100–110 mmHg over the next several hours, and finally normalize over 24-48 hours. Reducing MAP by no more than about 25% helps avoid causing hypoperfusion to the brain, heart, or kidneys. That’s why the statement is true: you should avoid large drops too quickly and pace the reduction to about a 25% MAP decrease in the early period, with careful titration thereafter. Larger, faster drops (like 30% in 12 hours or 60% in 24 hours) risk ischemia and are not appropriate initial targets.
