In acute stroke evaluation, what is the primary reason to check the blood glucose level?

• A. To rule out hypoglycemia
• B. To assess chronic diabetes
• C. To evaluate liver function
• D. To estimate renal clearance

Answer: (A)

The main idea is that metabolic problems, especially low blood sugar, can produce stroke-like neurologic symptoms. In the hyperacute stroke setting, you want to confirm that what you're seeing is due to a vascular event and not a reversible metabolic disturbance, because treatment decisions (like thrombolysis) depend on that distinction. A quick glucose check helps you rule out hypoglycemia as the cause; if glucose is low, you treat that first (and reassess), rather than proceeding with stroke therapies that could be inappropriate or unsafe. Once glucose is normal, you can continue the stroke evaluation with confidence.
