What is a required action when using the zigzag (Z-track) method for injections?

Using the zigzag (Z-track) method for injections involves specific techniques to ensure proper medication delivery and reduce discomfort. One of the required actions is indeed changing needles between drawing up and administering the medication. This practice is crucial because the needle used for drawing up the medication may have become dull or contaminated during that process. By switching to a new, sharp needle for the actual injection, the healthcare provider minimizes tissue trauma and helps ensure that the medication is delivered more effectively and with less pain to the patient.

In the zigzag method, the skin is pulled laterally to help seal the medication within the muscle tissue. This technique is particularly useful for administering irritating or staining medications, as it prevents leakage into the subcutaneous tissue. Thus, changing needles is essential not just for ensuring a clean injection but also for maintaining the integrity of the medication administration process.
