Answer to Question 1
ANS: C
Most infants can pull themselves to a standing position at age 9 months. Infants who are not able to pull themselves to standing by age 11 to 12 months should be further evaluated for developmental dysplasia of the hip. At 6 months, infants have just obtained coordination of arms and legs. By age 8 months, infants can bear full weight on their legs. Any infant who cannot pull to a standing position by age 1 year should be referred for further evaluation.
Answer to Question 2
ANS: C
Infants are usually in the secondary circular reaction stage from ages 4 to 8 months. This stage is characterized by a continuation of the primary circular reaction for the response that results. Shaking 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. Primary circular reaction stage marks the replacement of reflexes with voluntary acts. The infant is in this stage from ages 1 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.
