When doing a delt injection, do you go from the bottom up, top down, or just straight in? Or does it just matter that you get inside the muscle.
How far do you aspirate. Do you aspirate until you can see the bubble inside the syringe the whole syring, or just until you can see the bubble start to form towards the bottom where the the needle and syringe connect.
And last, when doing a calf injection do you go in to the outside of the calf or the inside?
