Question:
1. When performing quality control tests in the laboratory, the
phlebotomist must
A. ensure the specimen is collected properly.
B. document results in the log.
C. document results on the requisition form.
D. document results on the progress report.
Answer:
document results in the log.
Quality control (QC) is a set of procedures conducted before patient testing to assure
the test system is performing correctly. A test system includes all aspects of the test to be
performed including equipment and instrumentation. The quality control results must be
documented to prove they have been done and be within certain preset limits. If they
haven’t been properly documented, it will be assumed the QC was not run and therefore
the patient results are not valid. Ensuring the specimen is collected properly is an equally
important part of the test process, but not considered part of quality control. The QC
results are not documented on either the requisition form or progress report but
internally within the Laboratory to monitor accurate and medically useful patient results.
Question:
2. As the phlebotomist removes the cap from the needle
before a venipuncture, she notices the needle is bent. Which
of the following should the phlebotomist do?
A. File a report and return the needle to the manufacturer.
B. Inform the supervisor.
C. Recap the bent needle and put it aside.
D. Discard the needle and obtain a new one.
Answer:
Discard the needle and obtain a new one.
Rationale
As with any manufactured device, a certain number of items are expected to have
,defects. The vendor's good quality control program should find and prevent these from
getting out into the market. However, it is the phlebotomist's responsibility to assure the
equipment to be used for blood collection is acceptable before use on a patient. This is
why the needle is inspected after removing the cap for any defect including straightness,
burrs and an open lumen. Needles are never recapped. The needle and the holder,
syringe or butterfly to which it is attached should be placed in a sharps container.
Documenting the occurrence is always a good idea and if there are more instances within
a certain lot or shipment, the manufacturer should also be notified.
Question:
3. Which of the following storage conditions should be
verified when restocking blood collection tubes in the
laboratory?
A. type & quantity
B. quantity & expiration
C. expiration & temperature
D. temperature & type
Answer:
expiration & temperature
Rationale
Evacuated blood collection tubes are a manufactured item and are given an expiration
date beyond which the vacuum and integrity of the contents are not guaranteed. When
restocking tubes, the oldest are used first to avoid costly wasting of outdated equipment.
The tubes are maintained at room temperature (approximately 22 degrees C). The types
and quantities of tubes would be governed by the testing needs of the laboratory.
Question:
4. A phlebotomist is asked to perform a pregnancy test on a
urine sample. The test result is positive but the QC indicator
line does not develop. Which of the following should the
phlebotomist do?
A. Report the test as positive and document that the QC was
not functional.
, B. Report the test as negative because the QC was not
functional.
C. Obtain another pregnancy test cartridge and repeat the
test.
D. Ask for a new urine specimen.
Answer:
Obtain another pregnancy test cartridge and repeat the test.
Rationale
Quality control (QC) is performed to assure that a test system is working correctly before
patient results are reported. If the quality control indicator does not function properly,
the patient results cannot be released. In this case, the phlebotomist should obtain a new
cartridge and repeat the test. A new urine specimen will not change the qc results if the
cartridge is not reliable.
Question:
5. Which of the following is the additive/anticoagulant in the
light blue top tube?
A. EDTA
B. sodium citrate
C. lithium heparin
D. potassium oxalate
Answer:
sodium citrate
Rationale
Blood collection tubes are color coded to indicate their chemical contents. The light blue
top contains sodium citrate. The lavender top contains EDTA, the green heparin and the
gray potassium oxalate.
Question:
6. Which of the following tubes contains ethylenediamine
tetraacetic acid (EDTA)?
A. yellow
B. royal blue
