A70 mg/dL and 110 mg/dL
B40 mg/dL and 80 mg/dL
C110 mg/dL and 140 mg/dL
D20 mg/dL and 70 mg/dL
Answer & Solution
Correct answer: A. 70 mg/dL and 110 mg/dL
1. Receptors in the pancreas sense blood glucose and the islets respond to keep it in a narrow band.
2. That band runs from 70 mg/dL to 110 mg/dL.
3. Above the band insulin is released and body cells pull glucose out of blood.
4. Below the band glucagon is released and body cells put glucose back into blood.
5. The lower ranges offered describe hypoglycaemia and the higher one describes sustained hyperglycaemia.
