Answer to Question 1

ANS: C
Infants are usually in the secondary circular reaction stage from age 4 months to 8 months. This stage is characterized by a continuation of the primary circular reaction for the response that results. For example, shaking of a rattle is performed to hear the noise of the rattle, not just for shaking. The use of reflexes is primarily during the first month of life. The primary circular reaction stage marks the replacement of reflexes with voluntary acts. The infant is in this stage from age 1 month to 4 months. The fourth sensorimotor stage is coordination of secondary schemata. This is a transitional stage in which increasing motor skills enable greater exploration of the environment.

Answer to Question 2

ANS: A
The bones surrounding the posterior fontanel fuse and close by age 6 to 8 weeks. Ten weeks or longer is too late.
