A nurse is teaching a client who has diabetes mellitus. Which of the following should the nurse include as an expected finding of diabetic ketoacidosis (DKA?

A. Weight gain of 0.45 kg (1 lb) in 24 hours: DKA is associated with dehydration due to osmotic diuresis, often leading to weight loss rather than gain. Small weight gain is not an expected finding in this condition. B. Rapid, shallow respirations: DKA typically causes Kussmaul respirations, which are deep and rapid, as the body attempts to compensate for metabolic acidosis. Shallow respirations do not reflect the classic compensatory response. C. Decreased urine output: Polyuria is more common in DKA due to hyperglycemia-induced osmotic diuresis. Reduced urine output may occur only in severe dehydration or renal impairment, not as an initial finding. D. Blood glucose levels 300 mg/dL: Hyperglycemia is a hallmark feature of DKA, with blood glucose often exceeding 250 mg/dL. Elevated glucose contributes to osmotic diuresis, dehydration, and electrolyte imbalances characteristic of the condition.
