What is the dose and route for glucagon in this protocol?

• A. 2 mg intramuscularly
• B. 1 mg intramuscularly
• C. 0.5 mg intravenously
• D. 1 mg subcutaneously

Answer: (B)

Glucagon is used in an acute hypoglycemic emergency when the patient cannot take sugar orally, because it tells the liver to release stored glucose and quickly raise blood sugar. In this protocol the standard approach is to give 1 mg by intramuscular injection. The intramuscular route is chosen because it can be administered rapidly without needing venous access, delivering a dependable, fast rise in glucose in a stressful dental emergency. Higher doses aren’t used here, and while intravenous or subcutaneous routes can be options in other settings, this protocol specifies intramuscular administration for practicality and reliability in a dental clinic. After giving it, monitor the patient and if there’s no improvement within about 10–15 minutes, follow the emergency plan, including seeking help and continuing glucose management once the patient can safely swallow.
