The following results are from a 21... -year-old patient with a back injury who appears otherwise healthy: whole blood glucose: 77 mg/dL (4.2 mmol/L) serum glucose: 88 mg/dL (4.8 mmol/L) CSF glucose: 56 mg/dL (3.1 mmol/L) The best interpretation of these results is that: Correct Answer: all values are consistent with a normal healthy individual The preparation of a patient for standard glucose tolerance testing should include: Correct Answer: a high carbohydrate diet for 3 days If a fasting glucose was 90 mg/dL, which of the following 2-hr postprandial glucose results would most closely represent normal glucose metabolism? Correct Answer: 100 mg/dL (5.5 mmol/L) Normal 2-hour postprandial value. A healthy person with a blood glucose of 80 mg/dL (4.4 mmol/L) would have a simultaneously determined cerebrospinal fluid glucose value of.
