Hey guys, I posted this before but it was erased last time the board went down. It is the actual procedure to do IM injections directly out of my nursing textbook. So here it is again, hope it helps somebody.
It is recommended that, when administering IM injections, the Z-track method be used to minimise irritation by sealing the medication in muscle tissue. The nurse selects an IM site, preferably in larger, deeper muscles such as the ventrogluteal muscle. A new needle must be applied to the syringe after preparing the medication so that no solution remains on the needle shaft. After preparing the site with an antiseptic swab, the nurse pulls the overlying skin and subcutaneous tissues approximately 2.5-3.5 cm (1-1.5 in) laterally to the side. Holding the skin taut with the nondominant hand, the nurse injects the needle deep into the muscle. With practice, the nurse learns to hold the syringe and aspirate with one hand. The nurse injects the medication slowly if there is no blood return on aspiration. The needle remains inserted for 10 seconds to allow the medication to disperse evenly. The nurse then releases the skin after withdrawing the needle. This leaves a zig-zag path that seals the needle track where the tissue planes slide across each other. The medication can not escape from the muscle tissue.
Here is the diagram.
