I would ask this question to the nurses on my unit but I've already asked them a million questions already, so maybe someone here can help me. When you give a medicine IVP do you usually dilute it in NS. I know morphine, phenergan, you should dilute but what about other drugs? I had to give Solumedrol 125mg/2ml IVP the other day and I didn't know if I had to dilute it but I just did anyway to be on the safe side.
