The proper technique for administering a Z-track injection is to (695) a. insert the needle at a 45 -degree angle. b. use a $3^{\prime \prime}$ needle at a 45 -degree angle. c. insert the needle at a 90-degree angle and pull the tissue laterally before removing the needle. d. pull the tissue at the site laterally, then insert the needle at a 90-degree angle.

Key Concepts

Z-Track Injection

A Z-track injection is a specific intramuscular injection technique that involves laterally displacing the skin and subcutaneous tissues before needle insertion. This creates a seal that prevents the medication from leaking back through the needle track into the subcutaneous tissue, thereby ensuring a more effective delivery into the muscle.

Intramuscular Injection

Intramuscular injection is a method of introducing medication deep into the muscles, which allows for rapid absorption into the bloodstream. It is important to use proper technique and equipment, such as the correct needle size and insertion angle, to ensure the medication reaches the muscle tissue without causing unintended side effects.

Needle Insertion Angle

The angle at which the needle is inserted is crucial for achieving accurate and effective delivery of medication into the muscle tissue. In the context of intramuscular injections like the Z-track method, a 90-degree angle is essential to penetrate straight into the targeted muscle and avoid subcutaneous tissue.

Tissue Displacement

Tissue displacement refers to the act of pulling the skin and subcutaneous tissues laterally prior to needle insertion in a Z-track injection. This displacement, if maintained during the injection, helps trap the medication in the muscle by sealing off the needle track when the tissue is released after the injection, thus reducing medication leakage.
