Use a brand new needle. Usually the doc orders 5,000 units (1cc vial) of heparin SQ Q12H. We have prepackaged 3cc syringes with a 23-gauge 1" needle. I'll use that to draw it up and then switch out for brand new 5/8" needle. No one has really ever said a word but it also depends on the patient.
And PLEASE rotate sites!!!! I took care of a patient who was getting Lovenox injections in the same side/area for 3 days and there was a TON of bruising and it felt like a VERY hard mass in the area
I don't know what that nurse or those nurses who had this patient before me were thinking
