What BP threshold is stated for proceeding with thrombolysis in this material?

• A. Under 140/90
• B. Under 160/100
• C. Under 180/105
• D. Under 200/110

Answer: (C)

Controlling blood pressure before giving thrombolysis is essential to reduce the risk of hemorrhagic complication while still enabling timely reperfusion. In this material, the threshold is to proceed when blood pressure is under 180/105. This level provides a safe balance: it lowers the chance of bleeding into the brain without delaying treatment excessively. If the patient’s pressure is above that, you would rapidly lower it with IV antihypertensives (like nicardipine or labetalol) and reassess until the measurement falls to or below 180/105, then move forward with thrombolysis per protocol. Thresholds that are much lower could unduly delay therapy, while higher thresholds would increase bleeding risk, so the 180/105 target is chosen to optimize safety and timeliness.
