Which statement is accurate about the recommendations for BP management after an ischemic stroke?
The BP must be lower than 130/70 mm Hg to receive fibrinolytic agents.
Elevated BPs are expected after a stroke, and drug therapy should be initiated.
A lower BP is a protective response to maintain cerebral perfusion.
Drugs to lower BP are recommended if the BP is 220/120 mm Hg or higher
The Correct Answer is D
A. The BP must be lower than 180/105 mm Hg to receive fibrinolytic agents, not 130/70 mm Hg.
B. Elevated BPs are common immediately after a stroke, but drug therapy to lower BP is not initiated unless it reaches high levels (typically > 220/120 mm Hg).
C. A lower BP does not act as a protective response; maintaining a higher BP can be necessary initially after a stroke to ensure adequate cerebral perfusion.
D. If BP is 220/120 mm Hg or higher after ischemic stroke, aggressive antihypertensive therapy is initiated to reduce the risk of hemorrhagic transformation and other complications.
