Answer to Question 1

ANS: C
Head circumference begins larger than chest circumference. Between ages 1 and 2 years, they become approximately equal. Head circumference is larger than chest circumference at ages 1 month and 6 to 9 months. Chest circumference is larger than head circumference at age 2.5 to 3 years.

Answer to Question 2

ANS: B
Satisfactory radial pulses can be used in children older than 2 years. In infants and young children the apical pulse is more reliable. The radial pulse can be used for assessment at ages 3 and 6 years.
