Correct Answer » A
Explanation

–Clinical Reasoning for the Correct Answer:
– Acute management of SAH prioritizes the prevention of further brain injury.
– Nimodipine, a calcium channel blocker, is administered immediately to reduce the risk of delayed cerebral ischemia (vasospasm), a major cause of morbidity and mortality post-SAH.
– Identification of the bleeding source (aneurysm) is necessary, but stabilization and prevention of secondary insults take precedence.
Why Option A is Correct:
– Nimodipine is started as soon as SAH is diagnosed to limit risk of cerebral vasospasm and improve neurological outcomes.
– It is the only drug proven to reduce the risk of poor outcomes after SAH.
Why Option B is Incorrect:
– Conventional angiography for aneurysm identification is necessary but not the immediate next step; initial stabilization, including nimodipine, comes first.
– Angiography is performed after initial medical management and stabilization.
Why Option C is Incorrect:
– Urgent surgical intervention is not performed before the patient is stabilized and the aneurysm is accurately localized.
– Early surgical or endovascular repair is indicated but only after blood pressure management, prevention of rebleeding, and vasospasm prophylaxis.
Why Option D is Incorrect:
– Performing both nimodipine and angiography simultaneously is not possible.
– Nimodipine should be started immediately; angiography follows after stabilization, not concurrently.
