Question 6

Question
Whipple´s triad - Choose correct statement
Answer
  • Symptoms of hypoglycemia, lab evidence of hypoglycemia and symptoms are relieved by administration of glucose, low plasma glucose concentration
  • idk

Answer
  • 7
  • 7.8
  • 6
  • 6.8
  • 11.1

Question 8

Question
Reaction in hypoglycemia - Choose correct statement
Answer
  • Suppression of insulin, and decrease of catecholamines
  • Increase in glucagon and cortisol, decrease of growth hormone
  • 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
  • Extreme metabolic acidosis, due to impaired lactate metabolism in liver
  • Absent, low or high ketones

Question 10

Question
Diabetic ketoacidosis - Choose false
Answer
  • You should do arterial blood gas sample
  • Creatinine can be falsely measured due to elevated levels of ketone bodies interfering
  • Higher plasma glucose than hyperosmolar non-ketotic coma
  • Amylase activity is increased
