What key information should be documented for an insulin order on the MAR?

• A. Insulin type, dose, route (subcutaneous), time of administration, and any sliding scale or meal-related notes
• B. Brand name and vial color
• C. Insurance and billing codes
• D. Room location

Answer: (A)

Insulin orders on the MAR must capture the exact dosing and administration plan so care teams know when and how to give it. The best documentation includes the insulin type, the dose in units, the route (subcutaneous), the time of administration, and any sliding-scale or meal-related notes. Insulin type matters because different preparations have different onset and duration, which determines how quickly glucose will drop and when the next dose is due. The dose in units ensures accuracy and avoids confusion between measurements like mL. The route confirms subcutaneous injection. The time of administration is critical to coordinate with meal times and monitoring. Sliding-scale or meal-related notes provide the instructions for adjusting the dose based on glucose results or meal content, preventing mismatches that can cause hypo- or hyperglycemia. Other information such as brand name, vial color, insurance codes, or room location does not affect the delivery of the insulin and is not essential for the MAR entry.
