In this emergency protocol, how is glucose most commonly administered for hypoglycemia?

• A. Intravenous
• B. Orally
• C. Rectally
• D. Topically

Answer: (B)

When hypoglycemia occurs, the goal is to raise blood glucose quickly by a route that is practical and safe in the given setting. If the person is conscious and able to swallow, giving a fast-acting oral carbohydrate is the best option. Glucose tablets or gel, or a sugary drink totaling about 15 to 20 grams, can be swallowed right away and are absorbed quickly from the digestive tract. This approach avoids the need for injections or medical equipment and can be done immediately in most emergency dental or clinic situations.

Intravenous glucose is very effective and can raise blood sugar faster, but it requires IV access and trained personnel, so it’s reserved for more severe cases or when the patient cannot take anything by mouth. Rectal or topical glucose does not provide reliable, rapid correction in most emergencies and isn’t standard first line.

After giving oral glucose, recheck the patient’s condition in about 10 to 15 minutes and repeat if needed, switching to more definitive care if there’s no improvement or if the patient worsens.
