Choice 3 has BP > 180/120 PLUS end-organ damage findings (severe headache, vomiting, blurred vision, confusion suggest hypertensive encephalopathy or possible intracerebral hemorrhage). This is hypertensive EMERGENCY requiring ICU admission and IV antihypertensive (e.g., nicardipine, labetalol, clevidipine) titrated to controlled BP reduction (usually no more than 25% in the first hour). Choices 1 and 2 are hypertensive URGENCY (high BP, no end-organ damage) — managed with oral agent restart and outpatient follow-up. Choice 4 has BP below 180/120 and is asymptomatic, so it is not a hypertensive crisis.
In-depth explanation
The single distinguishing feature between emergency and urgency is end-organ damage — encephalopathy, ICH, MI, dissection, AKI, papilledema, pulmonary edema, eclampsia. The number alone does not define emergency. Rapid BP drop in urgency can cause stroke; titrate carefully (no more than 25% reduction in the first hour even in true emergency).
