Which is the most appropriate initial treatment for Diabetic ketoacidosis?
Answer and explanation
Correct answer: B. Intravenous fluids followed by a fixed-rate insulin infusion
- Step 1: Diabetic ketoacidosis is treated with intravenous fluids followed by a fixed-rate insulin infusion.
Answer
Intravenous fluids followed by a fixed-rate insulin infusion.
