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

A. Nephropathy: Kidney disease from diabetes is a long-term complication and would not produce the acute sweating, tremors, and lightheadedness described. B. Hypoglycemia: Sweating (diaphoresis), tachycardia, tremulousness, lightheadedness, and feeling shaky are classic acute manifestations of low blood glucose. C. Ketoacidosis: DKA is associated with hyperglycemia, dehydration, polyuria/polydipsia, and deep rapid respirations (Kussmaul); diaphoresis and tremor are not the typical early presentation. D. Hyperglycemia: High blood glucose usually causes polyuria, polydipsia, and dry skin rather than the cool, clammy diaphoresis and tremor seen with hypoglycemia.
