A nurse is administering an intramuscular injection to a client using the Z-track method.
Which of the following actions should the nurse take?
A.
Release the skin before withdrawing the needle.
B.
Insert at a 45° angle.
C.
Withdraw the needle quickly.
D.
Pull the skin laterally.
The correct answer and Explanation is :
The correct answer is D. Pull the skin laterally.
Explanation:
The Z-track method is a technique used for administering intramuscular (IM) injections to minimize the leakage of medication into the subcutaneous tissue and to reduce discomfort. This method is particularly useful when administering medications that are irritating or have the potential to stain the skin, such as iron preparations.
Here is a detailed explanation of the Z-track method:
- Pull the Skin Laterally (Option D):
- Before inserting the needle, the nurse should pull the skin and underlying tissue laterally or downward. This creates a zigzag or “Z” path that helps seal the medication in the muscle tissue and prevents it from leaking into the subcutaneous tissue. By displacing the skin and subcutaneous tissue away from the injection site, the medication is deposited deeper in the muscle and does not track back through the tissue layers.
- Insert the Needle at a 90° Angle:
- The needle should be inserted at a 90° angle to the skin, not at a 45° angle. This ensures that the medication is deposited into the muscle and not into the subcutaneous tissue.
- Withdraw the Needle Slowly:
- After injecting the medication, the needle should be withdrawn slowly and steadily. Pulling the needle out quickly can cause tissue damage or increase the risk of medication leakage.
- Release the Skin After Withdrawal:
- After withdrawing the needle, the nurse should then release the skin that was pulled laterally. This allows the tissue to return to its normal position, trapping the medication within the muscle layer and further reducing leakage.
By following these steps, the Z-track method helps in achieving proper medication delivery, reducing patient discomfort, and minimizing potential complications related to the injection.
