CCMA Phlebotomy Procedures 4

Question 1

A patient's arm shows signs of a hematoma forming during venipuncture. What is the FIRST action to take?

Accepted Answer

Apply pressure and remove the needle immediately

Answer

When a hematoma forms, the needle should be removed immediately and firm pressure applied to prevent further blood leakage into surrounding tissue.

Question 2

Which evacuated tube color is used for serum chemistry tests requiring no additive?

Accepted Answer

Red

Answer

Red-top tubes contain no additive and allow blood to clot naturally, producing serum for chemistry testing.

Question 3

What is the recommended angle of needle insertion for a standard venipuncture?

Accepted Answer

15–30 degrees

Answer

A 15–30 degree angle is recommended for venipuncture to enter the vein cleanly without passing through it.

Question 4

Which condition requires the phlebotomist to draw blood from the hand or wrist rather than the antecubital fossa?

Accepted Answer

Mastectomy on the ipsilateral side

Answer

Drawing from the arm on the same side as a mastectomy is contraindicated due to lymphedema risk, so alternate sites such as the hand are used.

Question 5

A phlebotomist notices the tube is not filling during an ETS draw. Which is the LEAST likely cause?

Accepted Answer

Patient's blood pressure is too high

Answer

High blood pressure would not prevent tube filling; it is more commonly associated with rapid, forceful filling rather than failure to fill.
