Question

Which parenteral route of administration uses the Z-track method?

1 Intravenous route
2 Intradermal route
3 Intramuscular route
4 Subcutaneous route

Answer 1

The Z-track method is used for the intramuscular route to prevent leakage and ensure proper medication absorption in the muscle.

Step-by-step explanation:

The Z-track method is a technique primarily used for the intramuscular route of drug administration. This method is designed to prevent leakage of the medication into the subcutaneous tissue, which can help minimize irritation and ensure that the medication is absorbed by the muscle tissue properly. As the needle is inserted deep into the muscle, the skin and subcutaneous tissue are displaced sideways before the injection, and then allowed to return to their normal position, effectively sealing the path and reducing leakage of the medication.
