A practical nurse (PN) is preparing to administer an intramuscular injection of prescribed iron dextran to an adult client using the Z-track method. In what order should the PN perform the following steps to ensure safe administration? Arrange the actions in the correct chronological sequence.
- 1Replace the needle used to draw up the medication with a new sterile administration needle.
- 2Retract the skin and subcutaneous tissue 1 to 1.5 inches laterally or downward.
- 3Insert the needle swiftly at a 90-degree angle into the selected muscle.
- 4Depress the plunger slowly to inject the medication and wait for 10 seconds.
- 5Withdraw the needle smoothly and simultaneously release the displaced skin.
Answer
The correct sequence is to first change the drawing-up needle, then retract the skin and subcutaneous tissue, insert the needle at a 90-degree angle, inject the medication while pausing for 10 seconds, and finally withdraw the needle while simultaneously releasing the skin.
The Z-track method requires strict adherence to a specific sequence to prevent tissue damage. First, a new needle must be attached to ensure the outside is free of irritating medication. Next, the skin is retracted to displace the tissue layers. The needle is then inserted at 90 degrees. After injecting slowly, a 10-second pause is necessary for medication dispersion. Finally, withdrawing the needle and releasing the skin simultaneously seals the track, trapping the medication in the muscle.
Step-by-Step Solution
Key Concept
The Z-track method for intramuscular injections is used to prevent highly irritating or staining medications from leaking back into the subcutaneous tissue by displacing tissue layers before injection.
