In suspected hypoglycemia, what is the first step to confirm the condition?

• A. Give sugary drink
• B. Check for sweating
• C. Call emergency
• D. Measure blood glucose

Answer: (D)

The essential idea is that you confirm suspected hypoglycemia with an objective blood glucose measurement rather than relying on symptoms alone. In a clinical setting, a quick finger-prick test using a glucometer provides a numerical value that shows whether the glucose is actually low. If the reading is low (for adults typically under 4 mmol/L or 70 mg/dL), you have confirmation and can proceed with fast-acting carbohydrate while monitoring the patient. If the reading is normal, the symptoms aren’t due to hypoglycemia, so other causes should be considered. Relying on a sugary drink without a glucose check risks giving treatment when it isn’t needed, and calling emergency is for severe situations or when the patient cannot safely be helped, not for initial confirmation. Measuring blood glucose gives the definitive confirmation you need to guide appropriate management.
