The nurse is providing teaching to a client admitted with a blood glucose level of 580 mg/dL about preventing complications related to diabetes mellitus. Which information reported by the client indicates understanding?

A. Keep diabetic medication on schedule as prescribed. This is the correct answer because maintaining a regular schedule for diabetic medication is crucial for managing blood glucose levels and preventing complications. B. Limit maximum daily fat intake to 15% of total calories. While reducing fat intake can be beneficial for overall health, it is not directly related to managing acute blood glucose levels or preventing immediate complications of diabetes. C. Check blood sugar levels every four to six hours every day. Frequent monitoring of blood sugar levels is important, but checking every four to six hours may not be necessary for all clients, especially if they are not on insulin or if their diabetes is well-controlled. It depends on individual needs and physician recommendations. D. Restrict alcoholic beverages to no more than 1-2 per week. Limiting alcohol intake is good advice for overall health and diabetes management, but it is not the most critical action compared to keeping medications on schedule to prevent complications.
