When can oral glucose be repeated after the initial administration?

The correct response regarding the timing for repeating oral glucose administration is based on the standard guidelines for treating hypoglycemia. After the initial dose of oral glucose is given, it is recommended to wait for 15 minutes before considering a repeat dose if there is no improvement in blood glucose levels.

This 15-minute interval allows enough time for the glucose to be absorbed and affect blood sugar levels adequately. Monitoring the patient's response during this period is essential, as it gives healthcare providers the opportunity to assess whether further intervention is necessary. Repeating the administration too soon may not allow for a proper assessment of the patient's condition and could delay appropriate treatment.

The other options suggest shorter or less appropriate intervals between doses, which do not align with the recommended practices for managing hypoglycemia effectively.
