A nurse is caring for a client who has diabetic ketoacidosis. Which of the following manifestations should the nurse expect?

Rationale: A. Malignant hypertension: While clients with DKA may have stress-related elevations in blood pressure, malignant hypertension is not a characteristic manifestation. DKA primarily presents with hyperglycemia, dehydration, and metabolic acidosis rather than extreme blood pressure elevation. B. Cheyne-Stokes breathing: Cheyne-Stokes respirations are typically associated with severe brain injury, heart failure, or central nervous system disorders. In DKA, clients exhibit Kussmaul respirations, which are deep and rapid, as a compensatory mechanism for metabolic acidosis. C. Acetone odor to breath: The presence of acetone or fruity-smelling breath results from ketone accumulation due to fat breakdown in the absence of sufficient insulin. This is a classic sign of diabetic ketoacidosis and reflects ongoing ketosis and metabolic derangement. D. Blood glucose level below 40 mg/dL: DKA is characterized by significant hyperglycemia, typically above 250 mg/dL. Hypoglycemia is not expected; instead, elevated blood glucose contributes to osmotic diuresis, dehydration, and electrolyte imbalances.
