The nurse observes the student administering an intramuscular injection using the Z-track technique. Which action reflects proper procedure?
1. The student inserts the needle at a 90 ° angle and then uses the radial side of the nondominant hand to pull the skin approximately 3 cm to the side.
2. The student uses the ulnar side of the nondominant hand to pull the skin approximately 2.5 cm to the side and inserts the needle at a 90 ° angle.
3. After injecting the medication, the student releases the skin and waits 10 seconds before removing the needle.
4. After injecting the medication, the student waits 5 seconds before removing the needle and releasing the skin.
Correct Answer: 2
The ulnar side of the nondominant hand is used to stretch the skin approximately 2.5 cm to the side, the needle is inserted at a 90 ° angle, and then the nurse waits 10 seconds before withdrawing the needle. The skin is not released until after the needle is withdrawn, which creates a cover over the injection site to reduce the risk of medication leaking from the muscle.
