What is the correct sequence of interventions for treating DKA, from first to last?

A) Fluid resuscitation, insulin administration, electrolyte correction, underlying cause treatment
B) Insulin administration, fluid resuscitation, electrolyte correction, underlying cause treatment
C) Electrolyte correction, fluid resuscitation, insulin administration, underlying cause treatment
D) Underlying cause treatment, fluid resuscitation, insulin administration, electrolyte correction

The correct intervention sequence for DKA is a) fluid resuscitation, insulin administration, electrolyte correction, then treatment of the underlying cause, which addresses dehydration, high blood glucose, electrolyte imbalance, and the root cause respectively.

Explanation:

This approach begins with fluid resuscitation to address the dehydration typically present in DKA patients. Dehydration occurs due to high glucose levels in the blood, which cause an increased osmotic pressure leading to decreased water reabsorption in the kidneys. Secondly, insulin administration helps to lower blood glucose levels by promoting its uptake into cells.

Thirdly, electrolyte correction is essential, as insulin therapy and fluid resuscitation can lead to shifts in potassium and other electrolytes. Finally, treating the underlying cause of the DKA, which could be an infection or poor management of diabetes, is paramount for preventing recurrence.
