1. 1. Following overnight fasting,

a <70 mg/dL (<3.9 mmol/L)
glycemia in adults.
b <60 mg/dL (<3.3 mmol/L)
c <55 mg/dL (<3.0 mmol/L)
d <45 mg/dL (<2.5 mmol/L)
2. 2. The following results are from a 21-year-old patient c all values are
consistent
with a back injury who appears otherwise fol- lowing
healthy: whole blood glucose: 77 mg/dL (4.2 2-hr
mmol/L) serum glucose: 88 mg/dL (4.8 postprandi
mmol/L) al glucose
CSF glucose: 56 mg/dL (3.1 mmol/L) results
The best interpretation of these results is that: would
a the whole blood and serum values are most
expected but the CSF value is elevated
b the whole blood glucose value should be
higher than the serum value
c all values are consistent with a normal
healthy indi- vidual
d the serum and whole blood values should be
identi- cal
3. 3. The preparation of a patient for standard
glucose tolerance testing should include:
a a high carbohydrate diet for 3 days
b a low carbohydrate diet for 3 days
c fasting for 48 hours prior to testing
d bed rest for 3 days
4. 4. If a fasting glucose was 90 mg/dL, which of the
