I'm new and trying to figure out some calculations for the NICU patient population. Could anyone help me? For example, the patient is receiving 12mls of milk Q3H. IV+PO is 5.5ml/hr. What is the IV rate? 12ml/3h would result in a rate of 4cc/hr, but I'm not sure how IV+PO fits in and need some help putting this all together. TIA!
