Which of these glucose levels is most likely to suggest the administration of oral glucose?

The administration of oral glucose is typically indicated when a patient is experiencing hypoglycemia, which is defined as a blood glucose level below 70 mg/dL in many guidelines. A glucose level of 64 mg/dL falls below this threshold, indicating that the patient may have insufficient glucose for normal brain function and could benefit from the rapid increase in blood sugar that oral glucose provides.

This intervention is particularly crucial for patients who are conscious and able to swallow, as it can quickly alleviate symptoms of hypoglycemia, such as confusion, weakness, and even loss of consciousness, if not addressed. In contrast, the other glucose levels listed are all above 70 mg/dL, suggesting that the patient is not hypoglycemic and therefore does not require oral glucose administration. These higher levels indicate that the patient’s blood sugar is likely within a normal or acceptable range.
