Before administering a regular insulin dose, which action is most appropriate?

• A. Review the patient's current insulin dose history
• B. Check blood glucose level
• C. Check blood pressure
• D. Check oxygen saturation

Answer: (B)

Assessing the patient’s current blood glucose is the key step before giving a regular insulin dose because insulin dosing is guided by the immediate glucose level. Knowing the present glucose helps determine whether a correction is needed and how much insulin to administer, so you treat the patient to a safe target range and avoid driving glucose too low. If the reading is in a normal range, you may not give a dose or you may adjust according to a protocol; if it’s elevated, a calculated correction dose can be given. Checking blood pressure or oxygen saturation doesn’t directly inform how much insulin to give, and while reviewing the patient’s insulin history is useful for broader management, the urgent, deciding factor before administration is the current blood glucose.
