1. A phlebotomist is preparing to collect a blood specimen from an inpatient who has a
fragile vascular system and rolling veins. Which of the following equipment choices is most
appropriate to ensure specimen integrity and minimize patient discomfort?
A. A standard 21-gauge straight needle with a 10 mL evacuated tube.
B. A winged infusion set (butterfly) connected to a evacuated tube holder or syringe.
C. An 18-gauge hypodermic needle with a syringe.
D. A lancet for capillary puncture.
ANSWER: B. A winged infusion set (butterfly) connected to a evacuated tube holder or
syringe.
Winged infusion sets provide superior control and flexibility when accessing fragile, small, or
rolling veins, reducing the risk of puncturing through the vessel wall. Option A uses a needle
that is too large for fragile veins. Option C is excessively large and intended for blood
donation or rapid infusion, not routine fragile-vein phlebotomy. Option D is a capillary device,
not suitable for larger multi-tube venous draws.
2. A patient experiences sharp, radiating pain and an electric shock sensation shooting
down their arm during a routine median cubital venipuncture. What is the immediate,
mandatory action the phlebotomist must take?
A. Continue the draw rapidly to finish filling the remaining tubes.
B. Immediately release the tourniquet, withdraw the needle cleanly, apply firm direct pressure
with gauze for a minimum of 3 to 5 minutes, and notify the physician or supervisor.
C. Twist the needle slightly inside the arm to reposition away from the nerve.
D. Ask the patient to ignore the discomfort and complete the procedure.
ANSWER: B. Immediately release the tourniquet, withdraw the needle cleanly, apply firm
direct pressure with gauze for a minimum of 3 to 5 minutes, and notify the physician or
supervisor.
An electric shock sensation indicates potential nerve contact or injury. Phlebotomy standards
dictate immediate discontinuation of the draw to prevent permanent nerve damage. Option A
and Option C exacerbate patient trauma and legal liability. Option D ignores critical safety
protocols.
,3. According to Clinical and Laboratory Standards Institute (CLSI) guidelines, what is the
correct order of draw for a light blue top tube, a lavender top tube, and a red top tube
using evacuated tube systems?
A. Lavender, Red, Light Blue.
B. Light Blue, Red, Lavender.
C. Red, Light Blue, Lavender.
D. All tubes can be drawn in any random order.
ANSWER: B. Light Blue, Red, Lavender.
The CLSI order of draw places coagulation tubes (light blue, sodium citrate) first to prevent
tissue thromboplastin or additive contamination from subsequent tubes. Non-additive or
serum tubes (red) come next, followed by EDTA tubes (lavender) last to prevent cross-
contamination of anticoagulants. Option A, C, and D violate established specimen integrity
rules.
4. A phlebotomist enters a patient's room and notices the patient is sleeping soundly. What
is the correct initial step before attempting venipuncture?
A. Shake the patient's shoulder firmly until they wake up.
B. Gently call the patient's name and tap the bedrail, never waking them abruptly or startling
them.
C. Draw the blood while the patient is asleep.
D. Leave the room and document that the patient refused.
ANSWER: B. Gently call the patient's name and tap the bedrail, never waking them
abruptly or startling them.
Patients must be fully awake, oriented, and able to provide informed consent before
phlebotomy procedures. Option A risks startling the patient and causing erratic movements.
Option C is unsafe and unethical. Option D is incorrect since the patient did not refuse.
5. Which of the following governmental agencies enforces workplace safety standards,
including the Bloodborne Pathogens Standard and the handling of sharps in medical
facilities?
A. Occupational Safety and Health Administration (OSHA).
B. Food and Drug Administration (FDA).
C. Environmental Protection Agency (EPA).
D. Centers for Disease Control and Prevention (CDC).
ANSWER: A. Occupational Safety and Health Administration (OSHA).
OSHA mandates safety regulations to protect workers from occupational exposure to
bloodborne pathogens and hazardous conditions. Option B regulates medications and devices.
,Option C handles environmental waste. Option D issues public health guidelines rather than
legal workplace enforcement.
6. A patient scheduled for a lipid panel asks if they failed to fast. Laboratory records show
the patient ate a heavy breakfast 30 minutes prior. What is the appropriate course of
action?
A. Draw the blood anyway and write "fasting" on the requisition form.
B. Notify the ordering provider or laboratory supervisor that the patient is non-fasting, as lipids
are significantly altered by recent food intake.
C. Tell the patient to throw up and proceed with the draw.
D. Cancel all future medical care for the patient.
ANSWER: B. Notify the ordering provider or laboratory supervisor that the patient is non-
fasting, as lipids are significantly altered by recent food intake.
Triglycerides and other lipid fractions elevate significantly after meals, leading to lipemic
serum and inaccurate clinical results. Option A falsifies clinical data. Option C and Option D
are extreme, unprofessional responses.
7. When performing a dermal puncture on an infant's heel, which anatomical area is
approved to avoid puncturing the calcaneus bone?
A. The central arch of the heel.
B. The medial or lateral plantar surface of the heel.
C. The direct posterior curvature of the heel.
D. The great toe tip.
ANSWER: B. The medial or lateral plantar surface of the heel.
Puncturing the medial or lateral plantar surface of the infant heel prevents osteomyelitis and
bone damage to the calcaneus, which lies close to the surface in the central heel. Option A, C,
and D violate pediatric phlebotomy safety guidelines.
8. Which additive is contained in a lavender-topped evacuated blood collection tube, and
what is its primary laboratory use?
A. Sodium citrate; used for coagulation studies.
B. EDTA; used for complete blood counts (CBC).
C. Heparin; used for chemistry tests.
D. No additive; used for blood bank serology.
ANSWER: B. EDTA; used for complete blood counts (CBC).
Lavender tubes contain EDTA (ethylenediaminetetraacetic acid), which binds calcium to
prevent clotting and preserves cellular morphology for hematology tests like the CBC. Option
, A describes light blue tubes. Option C describes green tubes. Option D describes red or gold
tubes.
9. A phlebotomist is drawing blood for a therapeutic drug monitoring (TDM) test where
the trough level is requested. When should the blood sample be drawn?
A. Immediately after the medication dose is administered.
B. Exactly 30 minutes before the next scheduled dose is administered.
C. Exactly two hours after the peak concentration.
D. At a random time during the day.
ANSWER: B. Exactly 30 minutes before the next scheduled dose is administered.
Trough levels represent the lowest concentration of a drug in the patient's bloodstream and
must be drawn immediately prior to the administration of the next dose. Option A measures
peak levels. Option C and Option D yield uninterpretable data for trough analysis.
10. What is the primary purpose of applying a tourniquet prior to performing
venipuncture?
A. To numb the skin over the vein.
B. To obstruct venous blood flow return to the heart, causing veins to distend and become more
palpable and prominent.
C. To completely stop arterial blood flow into the arm.
D. To sterilize the skin surface.
ANSWER: B. To obstruct venous blood flow return to the heart, causing veins to distend
and become more palpable and prominent.
Tourniquets impede superficial venous return, engorging the veins and making them easier to
locate and puncture. Option A is incorrect because tourniquets do not numb skin. Option C is
dangerous because arterial flow should never be occluded. Option D describes antiseptic prep.
11. A patient with a known history of severe latex allergy arrives at the outpatient
laboratory for blood work. Which precautionary measure is mandatory?
A. Use standard latex gloves and place a latex band on the patient.
B. Ensure all equipment, including tourniquets, gloves, and tape, is strictly latex-free to prevent
anaphylaxis.
C. Administer an antihistamine before using latex equipment.
D. Wear double latex gloves for protection.
ANSWER: B. Ensure all equipment, including tourniquets, gloves, and tape, is strictly latex-
free to prevent anaphylaxis.
