Clinical Chemistry Test 1

Following overnight fasting, hypoglycemia in non-diabetic adults is defined as a glucose of:

The results shown in this table are from a 21-year-old patient with a back injury who appears otherwise healthy:

test                                         result

whole blood glucose         77mg/dL(4.2 mmol/L)

serum glucose                    88mg/dL(4.8 mmol/L)

CSF glucose                         56 mg/dL (3.1 mmol/L)

The best interpretation of these results is that:

The preparation of a patient for standard glucose tolerance testing should include:

If a fasting glucose is 90 mg/dL, which of these 2-hour postprandial glucose results would most closely represent normal glucose metabolism?

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:

A 25-year-old man became nauseated and vomited 90 minutes after receiving a standard 75 g carbohydrate dose for an oral glucose tolerance test. The best course of action is to:

Cerebrospinal fluid for glucose assay should be:

Which of these 2-hour postprandial glucose values demonstrates unequivocal hyperglycemia diagnostic for diabetes mellitus?

Serum levels that define hypoglycemia in preterm or low birth weight infants are:

A 45-year-old woman has a fasting serum glucose concentration of 95 mg/dL (5.2 mmol/L) and a 2-hour postprandial glucose concentration of 105 mg/dL (5.8 mmol/L). The statement which best describes this patient’s fasting serum glucose concentration is:

Pregnant women with symptoms of thirst, frequent urination or unexplained weight loss should have which of the following tests performed?

In the fasting state, the arterial and capillary blood glucose concentration varies from the venous glucose concentration by approximately how many mg/dL (mmol/L)?

The conversion of glucose or other hexoses into lactate or pyruvate is called:

Which of these glycosylated hemoglobin is recommended by the ADA guidelines for testing diabetic patients?

A patient with hemolytic anemia will:
