Answer to Question 1

D

Feedback
A The newborn's body is able to constrict the peripheral blood vessels to reduce heat loss.
B Burning brown fat generates heat.
C The respiratory rate may rise to stimulate muscular activity, which generates heat.
D The newborn's flexed position guards against heat loss because it reduces the amount of body surface exposed to the environment.

Answer to Question 2

2
Rationale
1. The inability to phrase sentences is considered a delay if not done at 2 years.
2. A developmental milestone that can indicate learning disability if not met is a kindergartner unable to button.
3. Inability to sit still for a short story is considered a delay if the child is 35 years old.
4. Being unable to cut with scissors is considered a delay if not achieved by kindergarten age.
