- routine venipuncture
- capillary puncture
A: blood culture collection

Q: Which test is NOT usually done to detect clotting problems?

- PT
- glucose
- bleeding time
- platelet count
A: glucose

Q: The gray top tube is usually drawn for which test(s)?
- glucose
- PTT
- enzyme tests
- hematology tests
A: glucose

Q: The glucose tolerance test includes:
- administration of glucose
- multiple timed blood draws
- use of heparinized syringe
- both A and B
A: both A and B

Q: What is the purpose of the bleeding time test?
- to test the conversion of prothrombin to thrombin
- to perform platelet counts
- to assess platelet function
- none of the above
A: to assess platelet function

Q: Hypoglycemia is a condition of:
- high blood sugar
- high cholesterol
- low blood sugar
- low cholesterol
A: low blood sugar

Q: What is the best sample for urine collection?
- any random urine sample
- a catheterized urine sample
- a clean-catch midstream urine sample
- a sample from an ostomy bag
A: a clean-catch midstream urine sample

Q: The patient’s fasting glucose can be elevated if:
- the outpatient is on an antibiotic
- blood was collected without an antiglycolytic agent
- the patient ate before having blood drawn
- 1% to 2% iodine was used as an antiseptic during collection
A: the patient ate before having blood drawn

Q: Disturbing the platelet plug on a patient while performing a bleeding time will cause the results to be:
- falsely elevated
- falsely decreased
- either increased or decreased
- not affected at all
A: falsely elevated

Q: A properly collected 24-hour urine sample:
- starts with the first morning urine sample
- may contain a chemical preservative
- does not include urine voided while defecating
- is collected while the patient is fasting
A: may contain a chemical preservative

Q: In which test should alcohol NEVER be used to cleanse the venipuncture site?
- blood culture
- AIDS test
- blood alcohol level
- platelet count
A: blood alcohol level

Q: Glucose tolerance tests and therapeutic drug monitoring tests have which of the following collection requirements in common?
- fasting sample
- iced sample
- capillary puncture
- timed sample
A: timed sample

Q: When blood is drawn to monitor the therapy of a specific antibiotic, the peak level is drawn 1 hour after administering the antibiotic. The term used to refer to the antibiotic level drawn right before the antibiotic is given is called the:
- half-life level
- threshold level
- trough level
- toxicity level
A: trough level

Q: A phlebotomist is to collect a postdose level on a patient at 10:30. The phlebotomist is delayed in the collection, and collects the sample at 11:00. To hide the fact he was late for the collection, the phlebotomist enters 10:30 as the collection time. How will this affect the treatment of the patient?

Q: A GTT is being conducted on a patient. One phlebotomist collects the samples using a finger puncture, and the other phlebotomist collects the samples with a venipuncture. How will this cause a problem with the sequential results?
