Increase of insulin secretion
Increase in glucagon, cortisol, and growth hormone
Increase in insulin and catecholamines secretion
Question 9
Question
Lactic acidosis in diabetic decompensation - Choose correct statement
Answer
Due to hypoxia, and high anion gap
Normal anion gap
Due to extreme metabolic acidosis (>300nmol), high anion gap

Question
Diabetic ketoacidosis - Choose false
Answer
You should do arterial blood gas sample
