Today was my first day at clinical for the semester. My pt was on D5/0.45NS at a rate of 125cc/hr (1 L over 8 hours) q8h. Also, I noticed on the medication list that there are two PRN meds that are piggyback. On the med worklist, it says exactly this: Dilaudid 1 mg= 0.5ml IV q4h PRN Zofran 4mg=2ml IV q4h PRN I don't understand how you would piggyback these with the only the .5 ml for dilaudid and 2ml for zofran. I thought you needed a larger fluid voulme to piggyback...at least 50 cc? If someone could please help me and let me know if there is something I may be missing...that'd be great! THANKS
