Oral Glucose dose/route for an adult patient

• A. 1 tablet
• B. 2 tubes
• C. 1/2 tube orally
• D. 1 tube orally

Answer: (D)

The key idea is using a safe, rapid oral glucose dose for an adult who is conscious and able to swallow when hypoglycemia is suspected. One tube of glucose—about 15 grams—delivers a sufficient amount to raise blood sugar quickly without overdoing it. The glucose is absorbed through the mouth and cheek tissue (buccal absorption), so it acts fast and is easy to administer in the field.

Giving just one tube is preferred because it provides an effective amount with a low risk of excessive sugar, while keeping it simple and quick. A tablet may contain less sugar and can have variable absorption, making the effect less predictable. Two tubes could push the glucose too high and isn’t necessary initially. A half-tube might not raise the glucose enough to reverse symptoms promptly.

Remember to use oral glucose only if the patient can swallow and is not vomiting or at risk of aspiration. If the patient cannot swallow or remains unconscious, use other approved treatments and seek additional medical care.
