If there is a dosage that looks off I always double check with the doc, sometimes they have rationale for their dose, other times it is a mistake. For the fluids the above poster is correct. I also check to make sure they are urinating at least 1ml/kg/hr over a number of hours. If they are eating and drinking and their IV is at a low rate (or non-existent) I don't worry about fluid overloading. (Unless of course there is underlying pathology such as kidney or cardiac issues). Respiratory babies do better when they are not dehydrated.
