Correct answer: C — Lower blood pressure to 185/110 mmHg or less

The best answer is “Lower blood pressure to 185/110 mmHg or less”. Blood pressure must reach 185/110 mmHg or below before IV thrombolysis to limit intracranial-haemorrhage risk. Controlled rapid lowering is used without overshooting and compromising cerebral perfusion. Reperfusion assessment continues in parallel, including thrombectomy evaluation when indicated; aspirin is not given as a substitute during a thrombolysis decision.
