A nurse is caring for a diabetic patient with clinical manifestations of tremors, pallor, diaphoresis, and reports hunger. The nurse checks the patient's morning blood glucose, which is 60 mg/dL mild low. Which of the following nursing interventions is the MOST important?

Rationale: A. Keeping a patient NPO while they are hypoglycemic is unsafe. Hypoglycemia can rapidly progress and lead to seizures, loss of consciousness, or death. Immediate treatment of low blood glucose takes priority over fasting for labs. B. Waiting to contact the provider delays treatment. Mild hypoglycemia with symptoms requires immediate intervention. Delaying action could allow the blood glucose to drop further, increasing risk for severe complications. C. While monitoring is important, waiting an hour without intervening does not address the current hypoglycemia. Mild hypoglycemia should be treated immediately, then rechecked in 15 minutes after treatment. D. The “15-15 rule” is the standard initial treatment for mild hypoglycemia: give 15 grams of fast-acting carbohydrate, wait 15 minutes, and then recheck blood glucose. This intervention rapidly raises blood sugar, relieves symptoms, and prevents progression to severe hypoglycemia. Examples include 4–6 ounces of fruit juice, regular soda, or glucose tablets. This is the priority nursing action.
