1. A 27-year-old patient admitted with diabetic ketoacidosis (DKA) has a serum glucose level of 732 mg/dL and serum potassium level of 3.1 mEq/L. Which action prescribed by the healthcare provider should the nurse take first?

• A. Place the patient on a cardiac monitor
• B. Administer IV potassium supplements
• C. Obtain urine glucose and ketone levels
• D. Start an insulin infusion at 0.1 units/kg/hr

Correct Answer: Place the patient on a cardiac monitor

Rationale: In a patient with diabetic ketoacidosis (DKA), the initial priority is to assess for any cardiac arrhythmias due to electrolyte imbalances. Since the patient has a low serum potassium level of 3.1 mEq/L, placing the patient on a cardiac monitor is crucial to monitor for any potential cardiac complications. Administering IV potassium supplements (Choice B) may be needed, but it is not the first action to take. Obtaining urine glucose and ketone levels (Choice C) and starting an insulin infusion (Choice D) are important interventions in managing DKA, but ensuring patient safety by monitoring for arrhythmias takes precedence.
