What technique is used to ensure that medication does not track into subcutaneous tissue during intramuscular injections?

• A. Suction technique
• B. Swabbing technique
• C. Z-track method
• D. Direct injection method

Answer: (C)

The Z-track method is a technique specifically designed to prevent medication from leaking into subcutaneous tissue during intramuscular injections. This method involves displacing the skin and subcutaneous tissue laterally to one side during the injection. After the needle is inserted and the medication is injected, the needle is withdrawn while allowing the skin to return to its original position. This creates a "zigzag" path that seals the injection site, effectively keeping the medication in the muscle and minimizing irritation or staining of the surrounding tissue.

This technique is particularly useful for medications that can cause irritation or discoloration if they leak into the subcutaneous layer. Overall, the Z-track method enhances patient comfort and promotes the effectiveness of the medication administered via intramuscular route.
