1) Following overnight fasting, hypoglycemia in adults is defined
... [Show More] as a glucose of:
a. <70 mg/dL (<3.9 mmol/L)
b. <60 mg/dL (<3.3mmol/L)
c. <55 mg/dL (<3.0mmol/L)
d. <45mg/dL (<2.5mmol/L) - d (Diagnosis of hypoglycemia in adults.)
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 hrs. prior to testing
d. bed rest for 3 days - a (GTT diet preparation.)
4) If a fasting glucose was 90 mg/dL, which of the following 2 hr. postprandial glucose result would most closely represent normal glucose metabolism?
a. 55 mg/dL (3.0 mmol/L)
b. 100 mg/dL (5.5 mmol/L)
c. 180 mg/dL (9.9 mmol/L)
d. 260 mg/dL (14.3 mmol/L) - b (Normal 2 hour postprandial value.)
5) 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 mg/dL (1.4 mmol/L)
b. 50 mg/dL (2.3 mmol/L)
c. 100 mg/dL (5.5 mmol/L)
d. 150 mg/dL (8.3 mmol/L) - b (Ratio of CSF glucose to blood glucose)
6) A 25 yr. old man became nauseated and vomited 90 mins after receiving a standard 75 g carbohydrate dose for an oral glucose tolerance test. The best course of action is to:
a. give the patient a glass of orange juice and continue the test
b. start the test over immediately with a 50 g carbohydrate dose
c. draw blood for glucose and discontinue the test
d. place the patient in a recumbent position, reassure him and continue the test. - c (Use of partial GTT information.)
7) Cerebrospinal fluid for glucose assay should be:
a. refrigerated
b. analyzed immediately
c. heated to 56C
d. stored at room temperature after centrifugation - b (Effect of glycolysis on glucose.)
8) Which of the following 2 hr. postprandial glucose values demonstrates unequivocal hyperglycemia diagnostic for diabetes mellitus?
a. 160 mg/dL (8.8 mmol/L)
b. 170 mg/dL (9.4 mmol/L)
c. 180 mg/dL (9.9 mmol/L)
d. 200 mg/dL (11.0 mmol/L) - d (Unequivocal diagnosis of diabetes mellitus.)
9) A 45 yr. old woman has a fasting serum glucose concentration of 95 mg/dL (5.2 mmol/L) and a 2 hr. postprandial glucose concentration of 105 mg/dL (5.8 mmol/L). The statement which best describes this patient's fasting serum glucose concentration is:
a. normal; reflecting glycogen breakdown by the liver
b. normal; reflecting glycogen breakdown by skeletal muscle
c. abnormal; indication diabetes mellitus
d. abnormal; indicating hypoglycemia - a (Factors contributing to PBS.)
10) Serum levels that define hypoglycemia in pre-term or low birth weight infants are:
a. the same as adults
b. lower than adults
c. the same as a normal full-term infant
d. higher than a normal full-term infant - b (Age effect on glucose.) [Show Less]
