Hi all.. I just graduated from an LPN program here in Connecticut. I can tell you my instructor tested, re-tested and re-re-tested all of us on injection sites.
Maybe the nurse forgot and was trying to cover it up, but my first IM injection was in the glute... I didn't do any injections in the delt until I could tell my instructor 'alternate' sites for administration.
Proud to be ... a GPN

Step 1, change the S to a G.. Step 2, change that G to an L.
