An adult client is prescribed iron dextran via intramuscular injection. To prevent tissue irritation and skin staining, the practical nurse utilizes the Z-track technique. Place the steps of this administration technique in the appropriate chronological order, assuming standard pre-administration safety checks and hand hygiene have already been completed.
- 1Displace the skin and subcutaneous tissue laterally 1 to 1.5 inches (2.5 to 3.8 cm) away from the injection site.
- 2Dart the needle into the muscle at a 90-degree angle while maintaining tissue displacement.
- 3Administer the medication by pushing the plunger slowly and steadily.
- 4Hold the needle in place for approximately 10 seconds after the medication has been fully injected.
- 5Withdraw the needle smoothly and release the displaced skin and tissue immediately.
Cevap
The correct sequence for administering a Z-track intramuscular injection is to first displace the skin laterally, then insert the needle at a 90-degree angle, slowly inject the medication, hold the needle in place for 10 seconds, and finally withdraw the needle while simultaneously releasing the skin.
The Z-track method relies on misaligning tissue layers prior to injection. By displacing the skin first, inserting the needle, injecting, waiting for dispersion, and then releasing the skin simultaneously as the needle is removed, a broken (zigzag) path is created. This permanently traps the medication in the muscle layer.

Anahtar Kavram
The Z-track method is an intramuscular injection technique designed to trap medication in the muscle layer and prevent it from leaking into the subcutaneous tissue, thereby reducing irritation and staining.
