instead of saying decreased sub fat say, immature compensation for changes in environmental temperature. im doing the same thing but i only have to do three...lol. but im not sure about the risk of aspiration r/t to immature gag reflex. The healthy full term baby should have this reflex developed. Also, instead of extremes of age, I would put something r/t kidney function. Newborns have take a while before their kidney's can concentrate urine. If the baby were on IV fluids for some reason they can have fuild volume overload. i dont know. risk for fluid volume def r/t insensible water loss by large surface area and rapid res rate. Also at risk for jaundice r/t destruction of erthrpcytes created by a new increased oxygen filled environment.(or something like that)
