What range is typically aimed for after initial stabilization in malignant hypertension?

• A. 160/100 mm Hg within 2-6 hours, after an initial 25% drop in 1-2 hours
• B. 120/80 within 1 hour
• C. 140/90 within 24 hours
• D. 180/110 within 1 hour

Answer: (A)

In malignant hypertension, the goal is to reduce blood pressure gradually to avoid causing organ hypoperfusion while reversing end-organ damage. After initial stabilization, the typical target is to bring the BP down to about 160/100 within 2–6 hours, following an initial roughly 20–25% drop in the first 1–2 hours. This approach lowers danger from continued extreme hypertension but avoids dropping too fast or too far, which could compromise brain, heart, or kidney perfusion. Why this range fits best: it balances safety and effect. Dropping to 120/80 within 1 hour is often too aggressive and can cause hypoperfusion; allowing 140/90 within 24 hours is not aggressive enough to halt ongoing end-organ injury in a hypertensive emergency. Leaving BP at 180/110 within 1 hour fails to achieve meaningful stabilization and still poses high risk of damage. The chosen target—160/100 within a few hours after an initial partial drop—reflects a controlled, stepwise reduction designed for malignant hypertension.
