A nurse is assessing a client who is 4 hr postoperative following arterial revascularization of the left femoral artery. Which of the following findings should the nurse report to the provider immediately?

A. This is a serious complication in DKA, particularly in children, where the shift in osmolality during treatment can lead to fluid shifts into the brain. It can present with neurological deterioration, headache, altered mental status, and even coma.
B. Septic shock
While infection can precipitate DKA, septic shock itself is not a direct complication of DKA. However, DKA can predispose patients to infections due to impaired immune function, dehydration, and hyperglycemia.
C. Cardiac arrhythmias
Electrolyte imbalances, particularly hypokalemia or hyperkalemia (depending on treatment phase), can predispose individuals with DKA to cardiac arrhythmias such as ventricular arrhythmias (e.g., ventricular tachycardia) or atrial fibrillation.
D. Renal failure
Acute kidney injury (AKI) can occur due to dehydration, electrolyte imbalances, and the direct effects of acidosis. However, with prompt and appropriate treatment, renal function typically recovers.
E. Hypotension
Dehydration and volume depletion are common in DKA due to osmotic diuresis and fluid loss. This can lead to hypovolemic shock and hypotension if not adequately managed with fluid resuscitation.
F Respiratory alkalosis
DKA is associated with metabolic acidosis, not respiratory alkalosis. The body compensates for acidosis by increasing respiratory rate (Kussmaul respirations) to blow off CO2 and normalize pH, but this does not lead to respiratory alkalosis.

D. An oral airway is a device used to maintain a patent airway by preventing the tongue from obstructing the throat. It can be useful during or after a seizure to ensure the client can breathe effectively and to prevent airway obstruction due to tongue relaxation or loss of muscle tone.

A Wrist restraints are used to immobilize a client's wrists and are not typically indicated for seizure management. Restraining a client during a seizure can increase the risk of injury and hinder appropriate assessment and care

B. Nasogastric (NG) tubes are used for enteral feeding, medication administration, or gastric decompression. They are not directly related to managing seizures and are not typically required during or after a seizure episode. Therefore, an NG tube is not necessary in the client's room for seizure management.

C. Tongue blades are used to depress the tongue for examination of the mouth and throat, but they are not recommended during or immediately after a seizure. There is a common misconception that placing a tongue blade in the mouth prevents the tongue from being bitten during a seizure, but this can actually cause more harm, such as injury to the teeth or gums, during involuntary movements.
