Question

Quizplus · Accepted Answer

The nurse places the tourniquet around and above the selected site by 5 to 10 cm (3 to 4 inches)and tightens the tourniquet enough to occlude venous return but not distal pulses.A slipknot or a Velcro strip should be used for a quick,one-handed release of the tourniquet.The nurse should try to have the tourniquet in place for no longer than a minute,depending on the patient.The nurse is able to occlude the venous return without occluding arterial blood flow because the arterial system is a higher pressure system and thus requires more pressure to stop blood flow than a vein requires.
