Question: 1 / 400

Where should the tourniquet be placed on the patient during the venipuncture procedure?

1 inch above the venipuncture site

2 inches above the venipuncture site

3 inches above the venipuncture site

The appropriate placement of a tourniquet during a venipuncture procedure is typically 3 to 4 inches above the intended puncture site. Placing the tourniquet 3 inches above the site is generally effective for engorging the veins while still allowing for ease of access and ensuring that it does not interfere with the procedure itself. This distance helps optimize venous distension, making the veins more prominent and easier to puncture, which can enhance the success of the blood draw and reduce discomfort for the patient.

A tourniquet placed too close to the puncture site may restrict blood flow excessively, leading to complications such as hematoma formation or pain. Therefore, the recommended distance strikes a balance between effective venous engorgement and minimizing discomfort and risk to the patient.
