NCCT Venipuncture Procedures 2

Question 1

Which vein is the preferred first choice for routine venipuncture in the antecubital fossa?

Accepted Answer

Median cubital vein

Answer

The median cubital vein is the preferred first choice because it is typically the largest, most anchored, and least painful vein in the antecubital area, with fewer nearby nerves.

Question 2

At what angle should the needle be inserted during routine venipuncture?

Accepted Answer

15-30 degrees

Answer

The needle should be inserted at a 15-30 degree angle with the bevel up. This shallow angle allows smooth entry into the vein without puncturing through the opposite wall.

Question 3

What should the phlebotomist do immediately after removing the needle from the patient's arm?

Accepted Answer

Activate the needle safety device and apply pressure to the site with gauze

Answer

Immediately after needle removal, the safety device should be activated and pressure applied to the puncture site with clean gauze to prevent bleeding and hematoma formation.

Question 4

When performing venipuncture using the evacuated tube system, what indicates that the needle has entered the vein?

Accepted Answer

A flash of blood appears in the hub of the needle or tubing

Answer

A flash of blood in the needle hub or butterfly tubing confirms successful vein entry.

Question 5

Why is it important to release the tourniquet before removing the needle?

Accepted Answer

To prevent excessive bleeding and hematoma formation from the pressurized vein

Answer

Releasing the tourniquet before removing the needle reduces venous pressure, decreasing the risk of excessive bleeding and hematoma formation at the puncture site.
