A nurse is caring for a client who has type 1 diabetes mellitus. Which of the following conditions should the nurse monitor the client for due to the client's lack of insulin production?

Choice A rationale Hypoglycemia is generally a complication of diabetes treatment, such as excessive insulin administration or inadequate carbohydrate intake, rather than a direct result of the disease process itself. In type 1 diabetes, the primary physiological issue is the autoimmune destruction of beta cells, leading to a total lack of endogenous insulin. Without external insulin, blood glucose levels will rise, not fall. Therefore, the nurse monitors for hypoglycemia primarily as a side effect of the exogenous insulin therapy provided. Choice B rationale Neuroglycopenia refers to a shortage of glucose in the brain, which usually occurs when blood glucose levels fall below 50 mg/dL. While this is a serious concern for patients with type 1 diabetes who are receiving insulin, it is not the direct result of a lack of insulin production. In fact, a lack of insulin results in hyperglycemia, where there is plenty of glucose in the blood but it cannot enter the cells. Neuroglycopenia is a symptom of the treatment, not the underlying deficiency. Choice C rationale Insulin is the primary hormone responsible for glycogenesis, which is the conversion of glucose into glycogen for storage in the liver and muscles. In a client with type 1 diabetes, the absolute lack of insulin prevents the body from storing glucose effectively. Instead of increased storage, the body undergoes glycogenolysis and gluconeogenesis to further increase blood sugar levels. Thus, the nurse would expect to see depleted glycogen stores rather than an increase in storage due to the insulin deficit. Choice D rationale Diabetic ketoacidosis is a life threatening complication directly caused by an absolute lack of insulin in type 1 diabetes. Without insulin, the body cannot use glucose for energy and begins breaking down fats. This process produces acidic ketones, leading to metabolic acidosis. Clinical signs include Kussmaul respirations and a fruity breath odor. Laboratory findings typically show a blood glucose greater than 250 mg/dL, a serum bicarbonate less than 18 mEq/L, and a pH less than 7.30.
