What is the preferred method of glucose administration in alert patients?

Oral glucose is the preferred method of glucose administration in alert patients because it is safe, easy to administer, and effective in quickly raising blood sugar levels. When a person is conscious and able to swallow, oral glucose provides a direct source of sugar that can be rapidly absorbed into the bloodstream through the digestive system.

This method also allows for the patient to actively participate in their own care, making it less invasive than other methods like injections. Additionally, oral glucose is more convenient and can be administered without the need for medical professionals, allowing for quicker response times in managing hypoglycemic episodes.

In contrast, other methods like intramuscular or subcutaneous injections are typically used when a patient is unable to take oral glucose due to their condition or level of consciousness. Intranasal glucagon is also generally reserved for patients who are unconscious or unable to take food or drink and require rapid intervention. Therefore, when a patient is alert and able to ingest sugar, oral glucose is the most effective and appropriate choice.
