Question: 1 / 400

Which of the following is an important consideration when using a tourniquet to draw blood?

Leave the tourniquet on for no more than 5 minutes

Leaving the tourniquet on for no more than 5 minutes is a crucial consideration when drawing blood. The primary purpose of a tourniquet is to occlude venous return, which enhances vein prominence for easier access during venipuncture. If the tourniquet is left on for longer than 5 minutes, it can lead to complications such as increased hemolysis of the blood sample or could potentially cause discomfort and tissue damage to the patient due to prolonged constriction.

By adhering to the 5-minute rule, healthcare professionals can minimize the risk of adverse effects while still achieving the desired outcome of effectively accessing the vein. This practice ensures the integrity of the blood sample and the safety of the patient during the procedure.
