A patient is being treated for hypertensive emergency. When treating this patient, the nurse recognizes the initial goal is to lower the mean blood pressure (BP) by 20-25% because
the goal is to lower the BP to 120/80.
lowering the BP quickly may decrease cerebral, coronary or renal perfusion.
IV antihypertensive medications have a slow onset.
Lowering the BP slowly allows the patient to rest.
The Correct Answer is B
A. While lowering BP to 120/80 may be an ultimate goal, it is not the initial target in a hypertensive emergency.
B. Rapid reduction in blood pressure can cause hypoperfusion of vital organs such as the brain, heart, and kidneys, leading to ischemic injury. The aim is to reduce the BP gradually to prevent these complications.
C. IV antihypertensive medications generally have a rapid onset, not a slow one.
D. While gradual reduction is important, it is not done to allow rest but to protect organ perfusion.
