Which finding would lead the nurse to recheck the blood glucose level of a diabetic client before administering a mealtime insulin dose?

• A. Confusion
• B. Drowsiness
• C. Diaphoresis
• D. Nervousness

Answer: (A)

Recognizing hypoglycemia symptoms that warrant rechecking glucose before giving insulin. Insulin lowers blood sugar, so if the patient is showing signs that glucose is already low, administering more insulin could cause a dangerous further drop. Confusion reflects impaired brain function from low glucose (neuroglycopenia) and signals an urgent need to confirm the current glucose level before continuing with any mealtime insulin. If glucose is low, the appropriate action is to treat hypoglycemia and hold insulin until levels are safe. Other hypoglycemia signs like drowsiness, sweating (diaphoresis), or nervousness also indicate low glucose, but confusion is especially critical because it indicates the brain is not getting enough fuel and requires immediate assessment before proceeding with insulin.
