A 50-year-old woman on day 3 after a subarachnoid haemorrhage from an aneurysm treated endovascularly is alert with BP 134/80. She is prescribed nimodipine every 4 hours for 21 days. What is the main purpose of this drug?

1. To treat the headache only
2. To reduce brain injury from vasospasm
3. To stop the bleeding by promoting clotting
4. To prevent epileptic seizures

Answer: B) To reduce brain injury from vasospasm. Cerebral vasospasm typically occurs between days 3 and 14 and can cause ischaemia. Nimodipine improves outcomes; BP is monitored because it may fall.
