ASCP Chemistry Study Questions and Answers

Following overnight fasting, hypoglycemia and non-diabetic adults is defined as a glucose of 55mg/dl (3.0 mmol/L) The following results from a 21-year-old patient with a back injury who appears otherwise healthy Test result Whole blood glucose. 77 mg/dL (4.2 mil/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 All values are consistent with a normal healthy individual The preparation of a patient for standard glucose tolerance testing should be High carbohydrate diet for 3 days If a fasting glucose is 90 mg/dL, what two hour postprandial glucose results would most closely represent normal glucose metabolism 100 mg/dL (5.5 mmol/L) 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 50 mg/dL (2.3 mmol/L) CSF glucose is approximately _________ of blood glucose 60% A 25-year-old man became nauseated and vomited 90 minutes after receiving a standard 75 g carbohydrate does for an oral glucose tolerance test. The best course of action is to Draw blood for glucose and discontinue test Cerebrospinal fluid for glucose assay should be Analyzed immediately Which two hour postprandial glucose value demonstrates unequivocal hyperglycemia diagnostic for diabetes Mellitus 200 mg/dL (11.0 mmol/L) Serum levels that define hypoglycemia in preterm or low birth weight infants are lower than adults
