A client is admitted with diabetic ketoacidosis (DKA). Upon admission, the client was drowsy and nauseated with reports of a headache. An hour after admission, the practical nurse (PN) is assisting with the care of the client. Which finding is most important for the PN to report to the charge nurse?

A. Breath has a fruity odor: Fruity-smelling breath is a classic sign of ketoacidosis caused by elevated ketone levels. While important to monitor, it is expected in DKA and does not require immediate escalation. B. Client is not responsive: A sudden decrease in responsiveness indicates a potentially life-threatening complication, such as severe hyperglycemia, cerebral edema, or hypovolemia. Immediate reporting is critical to ensure rapid intervention and prevent further deterioration. C. Skin is flushed and dry: Flushed, dry skin is a common finding in DKA due to dehydration and hyperglycemia. Although it requires ongoing assessment and fluid management, it is not as urgent as changes in level of consciousness. D. Urine appears very dilute: Polyuria with dilute urine is expected in DKA due to osmotic diuresis. While monitoring fluid and electrolyte status is necessary, it does not constitute an immediate threat compared to unresponsiveness.
