Premature newborns have a decreased ability to maintain body heat. Which of the following are reasons for that decreased ability? Large body surface area.Thin skin layer.Reduced ability to intake calories.
An important part of environmental control is quiet times
Excessive intake of sodium in the postnatal period would lead to delayed contraction of the ECF
Teratogenic drugs generally have their greatest effect during the first trimester
