I'm just curious, do you use a lot of mixing/compounding calculations as hospital tech? I currently work at retail (less than 1yr), and I just passed the National PTCB exam last night. I'm thinking of making a switch to hospital but I feel intimidated by preparing IVs, compounding etc. Can anyone give me a little insight of what goes on in a hospital setting? Whom do you interact more? RN? MD? How many phone calls do you receive? As a retail tech, I have to pick up the phone stat or my store will lose points.
