I have a few questions about IM injects:
1. If you go through a blood vessel vein en route to the injection - but are not IN the blood vessel/vein at the final injection point, are you going to aspirate blood from having penetrated the vessel earlier?
2. If you do, in fact, aspirate blood, do you have to withdraw the needle completely, throw it away (test and all) and start over? I have read contrary information here. Some say throw the whole shebang away, some say go a little deeper/shallower, and try aspirating again, which brings me to my third question;
3. If you do hit a vein, aspirate blood and withdraw (or penetrate) a little more to try to get away from the vein, when you re-aspirate how would you know if you're getting "new" blood in the syringe or if it's the "old" blood from before?
4. Also, are you less likely to hit a vein doing a glute injection?
