Safety & CLIA Compliance with Verified Practice Questions
Question 1:
What is the primary purpose of phlebotomy?
A) To administer medications
B) To collect blood samples
C) To perform surgeries
D) To conduct physical examinations
CORRECT OPTION: B)
Rationale: The primary purpose of phlebotomy is to collect blood samples from
patients for various clinical testing, diagnoses, and donations.
Question 2:
Which vein is most commonly used for venipuncture?
A) Median cubital vein
B) Cephalic vein
C) Basilic vein
D) Jugular vein
CORRECT OPTION: A)
Rationale: The median cubital vein is typically preferred for venipuncture due to its size,
location, and minimal surrounding structures.
Question 3:
What is the appropriate procedure for applying a tourniquet during venipuncture?
A) Apply it tightly above the puncture site
B) Apply it snugly, ensuring blood pools
C) Leave it on for more than 1 minute
D) Use it only when necessary
CORRECT OPTION: B)
Rationale: A tourniquet should be applied snugly to engorge the veins for easier
puncture but should not be left on for too long.
Question 4:
What is the correct order of draw for blood collection tubes?
,A) Blue, Red, Green, Lavender
B) Lavender, Green, Red, Blue
C) Blue, Red, Green, Lavender
D) Red, Green, Lavender, Blue
CORRECT OPTION: C)
Rationale: Following the correct order helps to avoid contamination and ensures
accurate test results.
Question 5:
Which of the following is a common complication associated with venipuncture?
A) Infection
B) Hematoma
C) Hyperglycemia
D) Hypertension
CORRECT OPTION: B)
Rationale: A hematoma occurs when blood leaks into the surrounding tissue, often due
to improper technique.
Question 6:
What do venipuncture safety devices do?
A) Ensure faster blood draw
B) Decrease pain during puncture
C) Protect the healthcare worker from injury
D) Reduce the amount of blood needed
CORRECT OPTION: C)
Rationale: Safety devices are designed to protect healthcare workers from needle stick
injuries during and after blood collection.
Question 7:
What is the appropriate angle for the needle during venipuncture?
A) 15 degrees
B) 30 degrees
C) 45 degrees
D) 60 degrees
,CORRECT OPTION: B)
Rationale: A 30-degree angle is typically recommended for optimal access to the vein
without damaging the surrounding tissue.
Question 8:
Which additive is found in a lavender-top tube?
A) Sodium citrate
B) EDTA
C) Heparin
D) Gel separator
CORRECT OPTION: B)
Rationale: EDTA is an anticoagulant that binds calcium and is used for complete blood
count (CBC) tests.
Question 9:
What is the primary function of the serum separator tube?
A) To store blood
B) To protect veins
C) To separate serum from blood cells
D) To enhance coagulation
CORRECT OPTION: C)
Rationale: Serum separator tubes are designed to allow blood to clot and separate
serum for various tests.
Question 10:
Which of the following is a vital part of post-venipuncture care?
A) Applying pressure to the site
B) Changing the patient’s position
C) Removing the tourniquet immediately
D) Providing a glass of water
CORRECT OPTION: A)
Rationale: Applying pressure helps reduce the risk of bleeding and promotes clot
formation at the puncture site.
Question 11:
, What should you do if a patient feels faint during a blood draw?
A) Stop the procedure and help them lie down
B) Continue drawing blood
C) Give them water immediately
D) Call for assistance only
CORRECT OPTION: A)
Rationale: Helping the patient lie down can prevent fainting and ensure their safety
during the procedure.
Question 12:
What is the recommended method for disposing of used needles?
A) In regular trash
B) In a sharps container
C) In paper recycling
D) In biohazard bags
CORRECT OPTION: B)
Rationale: Used needles should be disposed of in a designated sharps container to
prevent needle stick injuries and ensure safe disposal.
Question 13:
What is hemolysis?
A) A type of infection
B) The breakdown of red blood cells
C) A coagulation disorder
D) A sample collection error
CORRECT OPTION: B)
Rationale: Hemolysis refers to the breakdown of red blood cells, which can affect
laboratory results.
Question 14:
What does a "fasting" requirement for a blood test mean?
A) No food only
B) No exercise
C) No medication
D) No food or drink for a specified time
