An adult client is prescribed an intramuscular injection of iron dextran. To minimize tissue irritation and prevent medication leakage into subcutaneous layers, the practical nurse administers the medication using the Z-track technique. Arrange the steps of this procedure in the correct chronological sequence.
- 1Displace the skin and subcutaneous tissue laterally away from the injection site.
- 2Dart the needle firmly into the muscle at a 90-degree angle.
- 3Push the plunger to inject the medication slowly and steadily.
- 4Wait for 10 seconds with the needle still inserted in the muscle.
- 5Withdraw the needle smoothly while simultaneously releasing the displaced skin.
Cevap
The correct sequence is to first displace the skin laterally, then insert the needle at a 90-degree angle, followed by injecting the medication slowly. After injecting, wait 10 seconds before finally withdrawing the needle and releasing the skin simultaneously.
The Z-track method is designed specifically to prevent medication leakage and tissue irritation. Displacing the skin first creates an offset track. Inserting the needle and injecting slowly ensures proper muscle delivery. Waiting 10 seconds allows the medication to disperse so it does not follow the needle out. Finally, releasing the skin exactly as the needle is withdrawn creates a zigzag tissue seal that traps the medication in the muscle.
