Oral glucose should generally be given to which type of patient?

Oral glucose is specifically indicated for patients who present with altered mental status and have a known history of diabetes. This is because these patients are at a higher risk of experiencing hypoglycemia due to their condition or treatment regimen. In cases where a diabetic patient shows signs of confusion, lethargy, or other changes in mental status, administering oral glucose can quickly elevate their blood sugar levels and help restore normal brain function.

The rationale behind this choice stems from the necessity to address low blood sugar levels effectively while simultaneously considering the patient’s diabetes history, which provides context for the likelihood of hypoglycemia. By ensuring that the patient is diabetic, you can more confidently administer glucose, thereby avoiding unnecessary risk in those who do not have a condition that predisposes them to low blood sugar.

In contrast, other scenarios may lead to complications if oral glucose is given indiscriminately. For example, providing glucose to unresponsive patients can be dangerous, particularly if they lack a gag reflex, as there is a significant risk of aspiration. Similarly, a precise blood glucose level must be confirmed in hypoglycemic episodes, which highlights the importance of knowing the patient's history and symptoms before administering glucose.
