Hi everyone, I am an RN and I am just starting a new job in community mental health, where we give many IM injections. In my previous job, I did not give IM's, and I only gave a couple back in school. Can someone answer a couple questions? 1) Do you have to Z-track in the deltoid - why or why not? 2) Some texts say you should draw up a tiny bit of air after you have drawn the correct dose because it locks the med into the muscle. I wasn't taught to do this in school, does anyone do this? 3) Upper quadrant versus VG site - I was taught in school to use VG to avoid the sciatic nerve, but everyone at work uses upper, outer quadrant, and that is what the patients expect and want. Is this safe? Thank you for your help!!
