What should be the first step when treating a known diabetic patient with altered mental status?

The first step in treating a known diabetic patient with altered mental status is to assess their blood glucose levels. This is crucial because alterations in mental status can indicate severe hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar), both of which are common among diabetic patients. By measuring glucose levels, you can quickly identify if the patient is experiencing a low or high blood sugar episode, which can guide immediate treatment.

In cases of hypoglycemia, quick intervention is necessary to prevent serious complications, such as seizures or loss of consciousness. Conversely, if the blood glucose level is high, it may indicate a need for different treatment methods, such as insulin administration or other interventions. Thus, determining the blood sugar level provides critical information and allows the healthcare provider to make informed decisions on how to proceed while ensuring the patient's safety.
