36) As blood flows down the tube, the phlebotomist should do which of the following?

(A) Instruct the patient to pump their fist.
(B) Instruct the patient to open their fist.
(C) Tighten the tourniquet.
D Loosen the tourniquet.

Answer 1

Phlebotomists should tighten the tourniquet to successfully draw blood.

Step-by-step explanation:

As blood flows down the tube, the phlebotomist should tighten the tourniquet. The tourniquet is a special band that is placed around the arm to help the veins swell with blood, making them easier to find and puncture. By tightening the tourniquet, the phlebotomist ensures that enough blood gathers in the vein for a successful draw. This action helps to prevent an unsuccessful or difficult blood draw and ensures a sufficient amount of blood is collected for testing.
