A nurse is contributing to the plan of care for a school-age child who is being admitted for diabetic ketoacidosis. Which of the following interventions should the nurse recommend?

A. Administer subcutaneous insulin 30 min before meals: In diabetic ketoacidosis (DKA), insulin is typically administered via IV infusion to allow for precise control of blood glucose and ketone levels. Subcutaneous insulin is introduced later during the recovery phase. B. Implement fluid restrictions: Children with DKA are often significantly dehydrated and require aggressive fluid resuscitation. Fluid restrictions would worsen dehydration and increase the risk of hypovolemic shock and impaired perfusion. C. Monitor vital signs every 8 hr: Vital signs should be monitored much more frequently than every 8 hours due to the risk of rapid deterioration. Close and frequent monitoring helps identify changes in perfusion, respiratory status, and neurological function. D. Initiate continuous cardiac monitoring: Continuous cardiac monitoring is essential in DKA because shifts in potassium levels can lead to life-threatening arrhythmias. Electrolyte imbalances, particularly hypokalemia, are common as insulin therapy progresses.
