PHLEBOTOMY PROCEDURES ACTUAL EXAM 2025 |144
QUESTIONS WITH ACCURATE SOLUTIONS
1. Explain why applying pressure after a blood draw is important in
the context of hemostasis.
It helps to cool the area and reduce swelling.
It promotes the formation of a platelet plug to stop bleeding.
It allows for the immediate analysis of the blood
sample. It prevents the patient from feeling faint.
2. After a needle puncture, if a patient bleeds excessively and
pulsating spurts and the blood is bright red, what is the most likely
cause?
an artery was punctured
the patient has a hematoma
the patient has a bleeding disorder
the patient is on anticoagulant therapy
3. In phlebotomy, which department is responsible for analyzing specimens
for lead testing?
Hematology
Microbiology
Toxicology
Immunology
4. Explain the significance of the reticulocyte count in the context of
diagnosing anemia and assessing bone marrow function.
It measures the total number of red blood cells in circulation.
It indicates the percentage of immature red blood cells
being produced by the bone marrow.
, It evaluates the levels of iron in the blood.
It assesses the presence of antibodies against red blood cells.
5. Explain why it is necessary to draw a discard tube before collecting the
PT and PTT tubes if the previous tube did not fill completely.
To avoid contamination from the previous sample
To ensure that the blood sample is not
hemolyzed To maintain the integrity of the
blood sample
To ensure the correct volume of blood is collected
6. In which area of laboratory diagnostics is DNA sample analysis
primarily conducted?
Hematology
Molecular Diagnostics
Microbiology
Immunology
7. A patient scheduled for a fasting blood glucose test has not adhered to
the NPO instructions. What potential impact could this have on the test
results, and how should the phlebotomist proceed?
The results will be accurate; proceed with the draw.
The results may be invalid; reschedule the test after
confirming NPO status.
The results will be lower than normal; proceed with the draw.
The results will be higher than normal; proceed with the draw.
8. Explain the significance of Troponin levels in the diagnosis of
myocardial infarction.
They indicate liver function
, They help assess kidney health
They are specific markers for heart muscle injury
They measure blood glucose levels
9. Explain the role of the National Accrediting Agency of Clinical Laboratory
Science (NAACLS) in phlebotomy training programs.
NAACLS provides funding for phlebotomy
programs. NAACLS develops new blood tests for
clinical use.
NAACLS sets standards and accredits educational programs
in clinical laboratory science.
NAACLS conducts blood draws for training purposes.
10. You must redraw a patient for potassium level because the first
specimen was hemolysed. Knowing that the patient is a difficult draw,
which of the following would you do to prevent hemolysis of the
sample?
Force the blood from a syringe into the vacutainer tube
Draw blood into a syringe while quickly pulling on the plunger
Use a 22g needle
Use winged infusion set
11. Explain what the term 'icteric' indicates about a blood specimen and
its potential implications for laboratory testing.
It indicates the specimen is contaminated and cannot be used.
It suggests the presence of excess bilirubin, which may affect test
results.
It means the specimen has been improperly stored and is
unusable. It shows that the specimen is rich in lipids, affecting its
clarity.
, 12. Explain the significance of molecular diagnostics in the context of
phlebotomy and specimen processing.
It focuses solely on blood typing.
It involves the analysis of genetic material for disease detection.
It is limited to testing for infectious diseases.
It primarily deals with blood coagulation studies.
13. When a phlebotomist enters an airborne isolation room, the appropriate
PPE would be
gloves, N95 respirator
gown, gloves, N95 respirator
gown, gloves, mask
gown, mask
14. What must a phlebotomist do when drawing blood from a patient with an
IV in their arm?
Use the opposite arm for the blood draw
Identify the draw location on the requisition
Notify the physician immediately
Perform a capillary blood draw instead
15. Explain why Chlorhexidine Gluconate is not recommended for infants
under two months of age.
It is too expensive for use on infants.
It can cause skin irritation and allergic reactions.
Infants have a higher risk of systemic absorption and toxicity.
It is less effective than other antiseptics for this age group.
