The nurse is caring for a client with diabetic ketoacidosis (DKA) receiving intravenous (IV) regular insulin. The most recent potassium was 2.9 mEq/L. The nurse should take which priority action:

Choice A rationale: A/V fistula assessment is not concerning because a positive bruit and thrill indicate adequate blood flow through the fistula. A dry dressing with scant amount of blood is expected after hemodialysis.

Choice B rationale: The client's low blood pressure could indicate hypotension, which can be critical, especially after hemodialysis. It may contribute to the client's reported dizziness and fatigue.

Choice C rationale: The client’s pulse is irregular which may indicate cardiac arrhythmia. Choice D rationale: Anuria, the absence of urine output, is a significant concern. It could indicate kidney dysfunction or inadequate clearance of waste products, which may have implications following hemodialysis.

Choice E rationale: Oxygen saturation at 92% is relatively low. While the client is alert and oriented, a low oxygen saturation level may indicate potential respiratory compromise or inadequate oxygenation.

Choice F rationale: Temperature is not concerning because it is within normal range.

Choice G rationale: Neurological assessment is not concerning because the client is alert and oriented. The dizziness is likely related to the hypotension and will resolve once the blood pressure is stabilized.

Choice A rationale: Assessing the UOP is important, but not as urgent as correcting the potassium imbalance.

Choice B rationale: Obtaining a 12-lead ECG can help monitor the cardiac status, but it does not address the cause of the problem.

Choice C rationale: The PMHCP can order potassium replacement to prevent cardiac arrhythmias and other adverse effects of low potassium levels.

Choice D rationale: Stopping the regular insulin infusion can worsen the DKA and increase the risk of cerebral edema and coma.
