Answer: A: Administering long acting antipsychotic 
Explanation: Z track technique Used for giving i.m. injections. In this technique, the skin and tissue are pulled and held firmly while injection is given, and after removing the needle, skin and tissue are released. This prevents tracking (leakage) of the medication into the subcutaneous tissue (underneath the skin) as the track that needle forms is zig zag and drug can't come out.
