Which of the following is a common treatment for hypoglycemia in an alert patient?

In cases of hypoglycemia, where a patient is alert and capable of swallowing, the administration of oral glucose is a common and effective treatment. Oral glucose is easily absorbed through the gastrointestinal tract, quickly raising blood sugar levels. This method is preferred in alert patients because it allows them to self-prescribe their treatment in a manner that is safe and straightforward.

When a patient is hypoglycemic but still alert, they can safely take oral glucose without the risks associated with injections that are required for interventions like glucagon or insulin. Glucagon, while useful in severe hypoglycemia when the patient is unconscious or unable to swallow, is not appropriate for an alert patient. Insulin would further decrease blood glucose levels and is not used in hypoglycemia. Administering water does not address the underlying issue of low blood sugar and would not provide any therapeutic benefit in this situation.
