A nurse is assessing a client who has type 1 diabetes mellitus and finds the client lying in bed, sweating, and reporting feeling anxious. Which of the following complications should the nurse suspect?

Rationale: A. Hypoglycemia: Symptoms such as sweating, anxiety, shakiness, and restlessness occur when blood glucose drops too low. These adrenergic responses result from activation of the sympathetic nervous system and are early warning signs of hypoglycemia in type 1 diabetes. B. Nephropathy: Diabetic nephropathy develops gradually due to long-term vascular damage in the kidneys. It presents with proteinuria, hypertension, and declining renal function rather than acute symptoms like sweating or anxiety. C. Hyperglycemia: Elevated blood sugar often causes gradual onset symptoms such as polyuria, polydipsia, and fatigue. It does not typically present with sudden adrenergic symptoms such as sweating and anxiety, which are more characteristic of hypoglycemia. D. Ketoacidosis: Diabetic ketoacidosis develops from prolonged hyperglycemia and insulin deficiency, leading to dehydration, abdominal pain, fruity breath, and Kussmaul respirations. It does not manifest with acute sweating and anxiety, which suggest hypoglycemia.
