Final answer:
Z-track injections are a technique used in administering medicine, mainly intramuscular injections, to minimize skin irritation and prevent leakage of medication into the subcutaneous tissues. This method is particularly useful when injecting highly irritating substances or those capable of staining the skin.
Step-by-step explanation:
The Z-track injection technique is used when administering medication, particularly intramuscular injections, to ensure minimization of skin irritation and avoid the leakage of the medication into subcutaneous tissues. The Z-track method involves pulling the skin and subcutaneous tissues about an inch away from the muscle during administering the injection. Releasing the skin after the injection will allow it to move back and seal in the medication, preventing leakage into subcutaneous layers.
This technique is often used when injecting highly irritating substances or medications that can stain the skin, like iron preparations. The Z-track method prevents medication from leaking back into the subcutaneous tissue and causing pain, irritation or discoloration. It also ensures that medication is delivered directly into muscle tissue, maximizing absorption and effectiveness.
