Question: 1 / 400

What should a phlebotomist do once the needle is inserted and blood begins to flow?

Change the needle

Release the tourniquet

Once the needle is inserted and blood begins to flow, it is important for the phlebotomist to release the tourniquet. The purpose of using a tourniquet is to temporarily restrict blood flow and make veins more prominent for easier access. However, once blood flow is established, maintaining the tourniquet can lead to complications, such as hemoconcentration, which may alter the quality of the blood sample.

Releasing the tourniquet allows for normal blood circulation and helps ensure that the sample collected accurately reflects the patient's true condition. This action is crucial for maintaining the integrity of the sample being drawn and prevents any potential complications that might arise from leaving the tourniquet on for too long.
