Rationale for newborn assesments.

Hi, I'm a nursing student and I have being trying to search for the answers but i've been having no luck so I was hoping someone could help me out and point me to the right direction.
I need the rationale, as well as a reference to where I found the information, for:

General appearance
Head
Face
Chest
Abdomen
Extremities
Back
Genitals
Parameters of growth
Feeding

Thank you!
