A practical nurse is preparing to administer an intramuscular (IM) injection of iron dextran using the Z-track method to an adult client with severe anemia. Arrange the following steps in the correct chronological order to ensure safe and effective medication administration.

  1. 1Cleanse the selected ventrogluteal site with an antimicrobial swab and allow it to dry completely.
  2. 2Displace the skin and subcutaneous tissue laterally 1 to 1.5 inches (2.5 to 3.8 cm) from the injection site.
  3. 3Insert the needle quickly at a 90-degree angle and steadily inject the medication.
  4. 4Keep the needle in place for 10 seconds after the medication has been fully injected.
  5. 5Withdraw the needle smoothly and immediately release the displaced skin.

Cevap

The correct sequence for administering a Z-track intramuscular injection begins with site cleansing, followed by displacing the skin laterally, inserting the needle and injecting the medication, waiting 10 seconds, and finally withdrawing the needle while releasing the skin.
Safe administration using the Z-track method requires strict adherence to sequential steps: proper hygiene and cleansing, lateral skin displacement to shift tissue planes, correct angle of insertion, a mandatory 10-second pause for dispersion, and simultaneous needle withdrawal and skin release to properly seal the track.

Adım Adım Çözüm

1
Cleanse the injection site.
The skin is free of surface pathogens.
Reduces the risk of introducing bacteria into the deep muscle tissue during needle insertion.
2
Displace the skin and subcutaneous tissue.
The tissue layers above the muscle are shifted away from their resting alignment.
Creates an angled track that will trap the medication in the muscle once the skin is released.
3
Insert the needle and inject the medication.
The medication is delivered directly into the ventrogluteal muscle.
Iron dextran is highly irritating and can stain subcutaneous tissues, so it must be deposited deep within the muscle.
4
Wait 10 seconds before withdrawing the needle.
The medication begins to absorb and disperse.
Prevents the medication from being forced back up the needle track by muscle pressure.
5
Withdraw the needle and release the skin.
The tissue layers slide back into their natural position.
Breaks the alignment of the needle track through the tissue layers, sealing the medication inside the muscle.

Anahtar Kavram

The Z-track method for intramuscular injections prevents highly irritating or staining medications from leaking into the subcutaneous tissue by creating a zigzag path through the tissue layers.
