NCCT Collection Complications and Corrections 3

Question 1

Which nerve is most commonly injured during venipuncture in the antecubital fossa?

Accepted Answer

Median cutaneous nerve

Answer

The median cutaneous nerve runs close to the basilic vein in the antecubital area and is the nerve most commonly injured during blood collection.

Question 2

What action should be taken when a patient has a mastectomy on one side?

Accepted Answer

Draw from the arm on the opposite side

Answer

Blood should be drawn from the arm opposite to the mastectomy because lymph node removal can impair circulation and immune function, increasing infection risk.

Question 3

A patient develops petechiae on their arm after tourniquet application. What does this indicate?

Accepted Answer

Platelet dysfunction or capillary fragility

Answer

Petechiae (tiny red spots) after tourniquet application indicate that small capillaries are breaking under pressure, suggesting platelet dysfunction or fragile capillary walls.

Question 4

What is the appropriate response if a phlebotomist accidentally punctures an artery during routine venipuncture?

Accepted Answer

Remove the needle immediately and apply firm pressure for at least 5 minutes

Answer

An accidental arterial puncture requires immediate needle removal and sustained firm pressure for at least 5 minutes to prevent a large hematoma due to arterial pressure.

Question 5

Which of the following is a consequence of prolonged tourniquet application (more than 1 minute)?

Accepted Answer

Hemoconcentration of large molecules

Answer

Prolonged tourniquet time causes hemoconcentration as fluid shifts from the vascular space into tissues, increasing the concentration of large molecules like proteins and cells.
