Final answer:
Z-track injections require the overlying skin to be pulled laterally. This technique creates a 'Z' track preventing the medication from leaking back into the subcutaneous tissue.
Step-by-step explanation:
When giving a Z-track injection, the overlying skin is pulled laterally.
The Z-track technique is often used in intramuscular injections to ensure medication does not leak back along the needle track and into the subcutaneous tissue, which can cause irritation or staining.
The technique involves displacing the skin and subcutaneous tissues laterally (to the side) before the injection and allowing it to return to its normal position after.
This creates a 'Z' track in the tissues, which effectively seals off the medication in the muscle.
