NRCMA Phlebotomy 2

Question 1

Which vein is considered the FIRST choice for venipuncture in most adult patients?

Accepted Answer

Median cubital vein

Answer

The median cubital vein is preferred because it is large, well-anchored, and least likely to roll.

Question 2

A patient reports feeling dizzy and lightheaded during venipuncture. What is the FIRST action the MA should take?

Accepted Answer

Remove the needle immediately and apply pressure

Answer

Removing the needle immediately prevents injury if the patient faints, and pressure stops bleeding.

Question 3

What does the term 'hemoconcentration' refer to in phlebotomy?

Accepted Answer

Falsely elevated analyte levels due to prolonged tourniquet use

Answer

Prolonged tourniquet application (>1 minute) causes fluid to shift out of capillaries, concentrating blood components.

Question 4

Which additive is found in a royal blue-top tube used for trace element testing?

Accepted Answer

EDTA or no additive (trace-element free)

Answer

Royal blue-top tubes contain either EDTA or no additive and are made with trace-element-free materials to prevent contamination.

Question 5

When performing a capillary puncture on an infant, which site is recommended?

Accepted Answer

Heel (plantar surface, medial or lateral)

The medial or lateral plantar surface of the heel is the standard capillary puncture site for infants to avoid bone injury.
