NCCT Practice Test Exam Questions
And 100% Correct Answers.
Which of the following actions should the phlebotomist take to decrease the potential for hemolysis of
blood specimen in an EDTA tube?
A. Store the tube in the refrigerator after the specimen has been collected
B. Use a 25 gauge needle or smaller to collect the specimen
C. Allow the tube to stand for 20 minutes prior to processing
D. Gently invert the tube after collecting the specimen - Answer Gently invert the tube after collecting
the specimen
Since an EDTA tube contains anticoagulant, it is important to immediately mix the blood as soon as it is
collected to ensure that it doesn't clot. The phlebotomist should gently invert the tube after collecting
the specimen to maintain specimen integrity and prevent rupture of RBC's in the sample.
Small red spots appear near the tourniquet on a patient's arm. This is MOST likely an indication of
A. a collapsed vein.
B. a hematoma.
C. petechiae.
D. edema. - Answer Petechiae
Small red spots near the tourniquet on a patient's arm are most likely indicative of petechiae. Petechiae
are small, red, non-raised spots that appear in response to pressure from the tourniquet.
Which of the following is outside the scope of practice for a phlebotomist?
A. Verifying equipment function on point of care testing using a control.
B. Prioritizing collections based on order requests.
C. Recording quality control results on a log sheet.
,D. Performing CLIA high complexity tests. - Answer Performing CLIA high complexity tests
CLIA refers to the Clinical Laboratory Improvement Amendment, which specifies personnel requirements
for performing laboratory testing based upon their complexity. Moderate and high complexity testing are
outside the scope of practice for a phlebotomist. Medical assistants may perform CLIA-waived testing,
such as Point of Care Testing, with proper training.
If a phlebotomist has questions about disposing of outdated hazardous chemicals, where should she
look to find this information?
A. HIPAA
B. MSDS
C. CLIA
D. NIOSH - Answer MSDS
A Material Safety Data Sheet (MSDS) is a hazardous chemical reference. It provides healthcare workers
with procedures for working with substances safety to ensure regulatory compliance.
When inserting a needle during venipuncture, the bevel should be in which of the following positions in
relation to the vein?
A. Up
B. Down
C. Left
D. Right - Answer Up
Which of the following is an example of a pre-analytical error made at the time of collection?
A. Delay in transporting
B. Failing to mix tubes
C. Incomplete requisition
D. Waiting to centrifuge - Answer Failing to mix tubes
,If the blood is not well mixed with the anticoagulant, partial clotting can occur leading to microscopic
fibrin strands and inaccurate test results.
Which of the following is the appropriate blood collection device for obtaining a blood spot collection on
an infant?
A. Syringe
B. Lancet
C. Micro-collection container
D. Evacuated tube - Answer Lancet
PKU is a neonatal screening test collected on a blot card. The recommended method of blood collection
on infants less than a year old is via capillary (thus eliminating the venipuncture choices)
A phlebotomist has orders to collect blood specimens from a patient who has IVs in his right forearm and
in the left antecubital area. Where should the phlebotomist collect a venous blood specimen?
A. The middle or ring finger of right hand
B. In the antecubital area of the right arm
C. Above the IV in the left arm
D. Distal to the IV in the left arm - Answer Distal to the IV in the left arm
Drawing in the antecubital area of the right arm or above the IV in the left arm would lead to
contamination of the sample with the fluid being administered. The test results would then reflect the
contents of the fluid or dilute the analyte to be measured. Incorrect patient treatment might result. In
this case, the safest place to draw would be distal to (away from) the IV left arm. The middle or ring
finger could be used for a dermal puncture but not for venous blood.
Which of the following actions is an example of compliance with Quality Control (QC) guidelines for
phlebotomy?
A. Check controls on urinalysis reagent strips daily.
B. Ensure supplies in venipuncture trays are no more than one month beyond the expiration date.
, C. Ensure reusable supplies in venipuncture trays are recycled.
D. Check glucometer controls monthly. - Answer Check controls on urinalysis reagent strips daily.
Proper Quality Control ensures accuracy and reliability of test results while detecting and eliminating
errors. It is an important component of patient care to make sure results are accurate, therefore it is
important to check controls on urinalysis dipsticks daily.
A patient on coumadin therapy is at the lab for a weekly coagulation test. Which of the following tubes
should the phlebotomist collect for this test?
A. Red top
B. Lavender top
C. Light blue top
D. Green top - Answer Light Blue Top
Sodium citrate (light blue top tube) is the anticoagulant of choice for coagulation studies such as PT/INR
(Protime/International Normalization Ratio) because it does not bind to calcium or inactivate heparin,
which may be required to be present in such testing
While performing a venipuncture, the phlebotomist removes the filled tubes, but forgets to remove the
tourniquet prior to needle withdrawal. Which of the following is the MOST likely result?
A. Syncope
B. Hemoconcentrated specimen
C. Hematoma
D. Hemolyzed specimen - Answer Hematoma
A hematoma is a large painful bruise at the puncture site, caused or created by blood seeping into the
surrounding tissues, one of the causes is the delay in tourniquet release and pulling the vacuum tube
out. Since the tourniquet is causing the veins to bulge this will prevent quick clotting, and cause bruising.
