When treating a conscious patient with hypoglycemia, what is the preferred method of glucose administration?

The preferred method of glucose administration for a conscious patient experiencing hypoglycemia is oral glucose. This approach is effective because conscious patients are typically able to swallow and tolerate oral intake. Administering glucose orally allows for a direct and safe way to restore blood glucose levels without the need for invasive procedures.

Oral glucose can come in various forms, such as glucose gel or simple carbohydrates, making it easy to administer and suitable for quick treatment. Additionally, this method has a low risk of complications when the patient can safely swallow.

In cases where a patient is unconscious or unable to swallow, alternatives such as IV glucose or intramuscular glucagon would be considered, but those do not apply here given that the patient is conscious. The nonrebreather mask is irrelevant in this scenario, as it is used for providing supplemental oxygen rather than treating low blood sugar. Thus, oral glucose is the most appropriate and practical choice for a conscious patient in this situation.
