Answer to Question 1

ANS: C
Rectal temperatures are avoided in the newborn. If done incorrectly, the insertion of a thermometer into the rectum can perforate the mucosa. Rectal temperatures, if taken correctly, are considered an accurate reflection of core body temperature. The inherent risks and intrusive nature limit the use. The time it takes to determine body temperature is related to the equipment used, not the route only.

Answer to Question 2

ANS: C
With the newborn quiet and in a supine position, the degree of flexion in the arms and legs and the arm recoil can be used to help determine gestational age. Length, weight, and the chest/head circumference reflect the newborn's size and weight, which vary according to race and gender. Birth weight alone is a poor indicator of gestational age and fetal maturity. The Apgar score is an indication of the newborn's adjustment to extrauterine life, and the mother's EDC is of no importance in determining gestational age.
