High-Yield Content
1. What is the anticoagulant of choice for blood for Prothrombin Time (PT)
testing?
EDTA
oxalates
sodium citrate
sodium flouride
2. Describe the purpose of using a winged infusion set during a hand draw
procedure.
The winged infusion set is primarily for arterial blood draws.
The winged infusion set is used to collect urine samples.
The winged infusion set is designed for easy access to small veins,
making it suitable for hand draws.
The winged infusion set is used for collecting blood from larger veins
only.
3. In a scenario where a patient has had multiple venipunctures on one arm,
what should the phlebotomist do regarding vein selection?
Choose the arm with the least visible veins to avoid complications.
Examine the antecubital veins of both arms to identify the best site
for venipuncture.
Only use the arm with the most visible veins regardless of previous
punctures.
Select a vein in the wrist area instead of the antecubital fossa.
,4. Why is it important to label specimens in front of the patient during blood
collection?
It is a requirement by laboratory regulations.
It ensures accuracy and helps prevent mislabeling, enhancing
patient safety.
It helps the patient feel more involved in the process.
It allows the phlebotomist to complete the task more quickly.
5. Why is it important for a patient to collect a semen specimen in a sterile
container?
To ensure the specimen is warm.
To make it easier to transport.
To increase the volume of the specimen.
To prevent contamination of the specimen.
6. Why is it important to limit the time a tourniquet is applied to a patient's arm
during blood collection?
It reduces the risk of infection.
Limiting the time prevents hemoconcentration and ensures accurate
test results.

It makes the procedure less painful for the patient.
7. Describe the significance of following the proper order of draw in blood
collection procedures.
The order of draw is irrelevant as all tubes are interchangeable.

It ensures confidentiality and proper handling of sensitive patient
information.
It reduces the workload of the lab technician.
It allows for quicker communication with the patient.
It is the only method allowed by law.
10. What is the initial action required before performing a blood collection?
Vein Location
, Patient Identification
Test Accession
Test requisition
11. Why is it important for a phlebotomist to inquire about a patient's last meal
before performing a GTT?
It is important because the GTT requires the patient to fast prior to
the test for accurate results.
It is important to ensure the patient is hydrated before the test.
It is important to check if the patient is allergic to glucose.
It is important to confirm the patient's identity before the test.
12. At home semen collection, patient indicating an understanding
I will collect in a sterile container and return it to the lab within 1
hour
collect in steril container and refrigerate
abstain from ejaculation for 12 hrs prior to the test
collect in clean condom and return in 3 hours
13. What is the correct method for cleansing the site before a routine
venipuncture?
Cleanse site in an outward spiral
Cleanse site in an inward spiral
Cleanse site with a scrubbing motion
Cleanse site in overlapping circles
