Which condition is a contraindication to oral glucose administration?

• A. Ability to maintain airway
• B. Nausea
• C. Decreased level of consciousness
• D. Normal blood glucose

Answer: (C)

The main idea is airway protection during suspected hypoglycemia. Oral glucose is given only when the patient can safely swallow and protect their airway. A decreased level of consciousness means the patient cannot safeguard the airway, increasing the risk of aspiration or choking if glucose is given by mouth. In this situation, oral glucose is contraindicated; treat with alternatives such as glucagon if IV access isn’t available, or intravenous dextrose if you have IV access, to raise blood glucose quickly without risking aspiration. If the patient can maintain their airway, oral glucose can be used; nausea alone isn’t a blanket contraindication unless it impairs swallowing or is accompanied by vomiting. Normal blood glucose isn’t a need for treatment, since the goal is to correct hypoglycemia when present.
