A patient with diabetic ketoacidosis is brought to the emergency department. Which prescribed action should the nurse implement first?

Option A is incorrect because administering an ACE inhibitor may be a part of the patient's regular medication regimen, but it is not specific to preventing complications of diabetes mellitus while in the hospital.
Option b is incorrect because administering intravenous fluids at a high rate may result in fluid overload, electrolyte imbalances, and other complications, which may not be appropriate for this patient.
Option c is incorrect because administering glucagon is not a preventative measure, but rather an intervention for treating hypoglycemia.
Option d is correct because ensuring a well-lit path to the bathroom is important for fall prevention, but it does not directly address the prevention of complications of diabetes mellitus.
Option e is incorrect because encouraging the client to drink sugar-free liquids is a general recommendation for maintaining hydration and may not be specific to preventing complications of diabetes mellitus.
Option f is correct because teaching the client to rise slowly from the bed is important for preventing orthostatic hypotension, but it does not directly address the prevention of complications of diabetes mellitus.
Option g is correct because Patients with diabetes mellitus are at risk for hypoglycemia when taking insulin or oral hypoglycemic agents. Proper coordination of meal-time insulin with food delivery and consumption can help prevent hypoglycemia or hyperglycemia. This includes ensuring that the patient receives insulin at the appropriate time in relation to meals and monitoring blood glucose levels regularly.

Glycosylated hemoglobin (HbA1c) is a measure of the average blood glucose levels over the past 2-3 months. An HbA1c level of less than 7% is associated with a reduced risk of microvascular and macrovascular complications in patients with diabetes. This is a critical goal because uncontrolled blood glucose levels can lead to complications such as neuropathy, nephropathy, retinopathy, and cardiovascular disease.

While options a, c, and d are also important in the management of diabetes, they are not as critical as achieving glycemic control. Choosing a diet that distributes calories throughout the day can help regulate blood glucose levels and prevent hypoglycemia. Following a diet and exercise plan that results in weight loss can also help improve glycemic control and reduce the risk of complications. Understanding the reasons for eliminating simple sugars in the diet is important for overall diabetes education, but it is not the most important goal in the plan of care for this patient at this time.
