Question

Quizplus · Accepted Answer

To use the Z-track method,apply the appropriate size needle to the syringe,and select an IM site,preferably in a large,deep muscle,such as the ventrogluteal.Pull the overlying skin and subcutaneous tissues approximately 2.5 to 3.5 cm (1 to 1½ inches)laterally to the side with the ulnar side of the nondominant hand.Hold the skin in this position until you have administered the injection.After cleansing the site,inject the needle deeply into the muscle.If there is no blood return on aspiration,slowly inject the medication.Keep the needle inserted for 10 seconds to allow the medication to disperse evenly.Then release the skin after withdrawing the needle.This leaves a zigzag path that seals the needle track wherever tissue planes slide across each other.The medication is sealed in the muscle tissue.
