Q1 Question 1 of 100
A 45-year-old patient presents to an outpatient laboratory for a routine metabolic panel. The phlebotomist
identifies the median cubital vein in the antecubital fossa as the preferred draw site. Identify the primary
anatomical reason this vein is the first-choice site for venipuncture.
A. It is large, well-anchored, close to the surface, and least likely to roll during needle insertion
B. It is the only vein in the arm that does not contain venous valves
C. It is located directly over the brachial artery, providing backup circulation
D. It has no nerve tissue within 2 centimeters of its path
Correct Answer: A
Rationale:
The median cubital vein is preferred because it is large, well-anchored, close to the surface, and least likely to roll, reducing
the risk of needle deviation and hematoma. All arm veins contain valves, the vein is not over the brachial artery, and no vein
is guaranteed to be nerve-free. Anatomical stability, not arterial proximity, determines first-choice selection.
Q2 Question 2 of 100
A phlebotomist is performing a venipuncture on a 60-year-old patient with fragile veins using a winged
infusion set (butterfly needle). The butterfly is connected to a multi-draw adapter and the first tube has just
filled. The phlebotomist notes the need to change tubes. Identify the correct technique for tube removal
during a butterfly draw to prevent vein collapse.
A. Pull the tube out rapidly while maintaining forward needle pressure
B. Place a finger on the tube adapter to prevent needle movement, then withdraw the tube gently and
straight
C. Loosen the butterfly needle slightly before removing the tube
D. Invert the tube before removal to ensure complete mixing
Correct Answer: B
Rationale:
During a butterfly draw, the phlebotomist must stabilize the adapter with a finger to prevent needle movement, then withdraw
the tube gently and straight to avoid dislodging the needle or causing vein collapse. Pulling rapidly destabilizes the needle,
loosening the needle risks vein injury, and inverting before removal is done after the tube is removed. Stability of the needle
is paramount during tube changes.

, Q3 Question 3 of 100
A 35-year-old patient requires a fingerstick capillary blood collection for a glucose measurement. The
phlebotomist selects the middle finger and must determine the correct puncture site and depth. Identify the
correct procedure for capillary puncture site selection and lancet depth.
A. Puncture the center of the fingertip pad at a depth of 3.0 millimeters
B. Puncture the side of the fingertip near the nail at a depth of 1.0 millimeter
C. Puncture the fleshy side of the fingertip off-center at a depth of 2.0 millimeters or less using a
spring-loaded lancet
D. Puncture the thumb pad at a depth of 4.0 millimeters for maximum blood flow
Correct Answer: C
Rationale:
Capillary punctures should be performed on the fleshy side of the fingertip, off-center, at a depth of 2.0 millimeters or less
using a spring-loaded lancet to minimize pain and avoid bone contact. The center pad is more sensitive, the nail-side risks
nail bed injury, and the thumb has thicker skin requiring deeper puncture. Warming the hand before puncture improves blood
flow.
Q4 Question 4 of 100
A phlebotomist must collect blood from a 70-year-old patient with a central venous catheter (CVC) in the right
internal jugular vein. The phlebotomist has been asked to draw from the line rather than performing
peripheral venipuncture. Identify the correct technique for drawing blood from a central venous catheter.
A. Withdraw blood directly from the catheter port without antiseptic preparation
B. Flush the line with saline first, then draw blood without discarding any volume
C. Disinfect the catheter hub with chlorhexidine, discard the first 5 to 10 mL of blood as a waste volume, then
collect the specimen
D. Apply a tourniquet above the catheter site before drawing blood
Correct Answer: D
Rationale:
Drawing from a central line requires disinfecting the hub with chlorhexidine, discarding the first 5 to 10 mL of blood as waste
to remove heparin or saline contamination, then collecting the specimen. Skipping antiseptic prep risks line infection, flushing
without a waste discard dilutes the specimen, and applying a tourniquet near a central line is contraindicated. The waste
volume may be reinfused per facility policy in some settings.

, Q5 Question 5 of 100
A 28-year-old patient presents for blood work requiring a coagulation panel (PT/INR and aPTT). The
phlebotomist must select the correct tube color and order of draw for this collection, which also includes a
CBC and a chemistry panel. Identify the correct tube selection and order.
A. Light blue (citrate) tube first, then lavender (EDTA) tube, then gold or tiger top (SST) tube
B. Gold or tiger top (SST) tube first, then light blue, then lavender
C. Lavender tube first, then light blue, then gold or tiger top
D. Light blue tube only; additional tubes are not required
Correct Answer: A
Rationale:
The CLSI order of draw is blood culture, light blue (citrate), serum tubes (gold/red/tiger top), green, lavender (EDTA), then
gray. For this collection, the light blue tube for coagulation comes first, then lavender for CBC, then SST for chemistry.
Serum tubes before citrate risks tissue factor contamination affecting PT/INR. EDTA before citrate interferes with coagulation
testing.
Q6 Question 6 of 100
A phlebotomist is preparing to perform a venipuncture on a 52-year-old patient with a mastectomy on the left
side three years ago. The patient has no IV lines or surgical shunts on the right arm. Identify the correct site
selection for this patient.
A. Either arm is acceptable because three years have passed since surgery
B. Draw from the right arm only, as the left arm is on the same side as the mastectomy and risk of
lymphedema exists
C. Draw from the left arm only to preserve the right arm for future IV access
D. Draw from either hand only, avoiding both arms entirely
Correct Answer: B
Rationale:
A mastectomy on the left side means the left arm is at risk for lymphedema due to lymph node removal, so blood should be
drawn from the right arm. Time since surgery does not eliminate the risk. Drawing from the affected arm risks lymphedema,
and avoiding both arms is unnecessary when the unaffected arm is available. If both arms are affected, a physician order is
required.
