- 6.A male patient has had successive fasting plasma glucose readings of 115, 110, and 122 mg/dl. The healthcare provider will inform him that
- A.
He appears to have impairment or borderline impairment of insulin-mediated glucose uptake by his cells.
- B.
He is quite normal and can stop requesting this blood test.
- C.
He needs more fasting plasma glucose because the range of these three values is too large to reach a conclusion.

He has developed diabetes and needs to adopt lifestyle changes.
- 7.To obtain an accurate spectrophotometric measurement of the glucose concentration in the sample
- A.
Barium hydroxide is added to prevent blood clots.
- B.
An enzymatic color reagent is added that digests and, thus, removes blood clots.
- C.
Water is added to dissolve the glucose.

- A.
She has specifically developed type 1 diabetes.
- B.
She is making too little glucagon and will need to consider supplements.
- C.
she has developed diabetes.
- D.
She appears to have impairment or borderline impairment of insulin-mediated glucose uptake by her cells.
- 10.To maintain plasma glucose homeostasis
- A.
Glucagon-mediated transport of glucose into cells acts as negative feedback when plasma glucose levels rise.
- B.
Cells will become unresponsive to insulin if plasma glucose levels are chronically low.
- C.
insulin-mediated transport of glucose into cells acts as negative feedback when plasma glucose levels rise.
- D.
The pancreas will release insulin and glucagon together in order to offset a rise in plasma glucose.

- B.
The plasma glucose concentration is expected to be lower in the index finger than in the arm vein.
- C.
The plasma glucose concentration in expected to be higher in the arm vein than in the index finger.
