Correct answer: C — Give oral glucose (15-20 g of fast-acting carbohydrate)

Hypoglycaemia (blood glucose <4.0 mmol/L, or <3.0 mmol/L with neuroglycopenic symptoms) in a conscious patient is treated with 15-20 g of oral fast-acting carbohydrate (glucose tablets, orange juice, regular soft drink). Symptoms include confusion, diaphoresis, tremor, tachycardia, and pallor. If unconscious, glucagon 1 mg IM or IV dextrose is administered. Dental appointments for insulin-dependent diabetics should be scheduled mid-morning after breakfast and insulin.
