A nurse is caring for a 10-month-old infant who is in a cast for developmental dysplasia of the hip (DDH). Which of the following strategies should the nurse implement to promote the infant's growth and development?

Rationale: A. Latex balloons are unsafe for infants due to the risk of choking and suffocation if they burst. B. Allowing the infant to stand in the crib is unsafe while in a hip cast and could compromise healing. C. Providing age-appropriate toys, such as small electronic or interactive toys, promotes sensory stimulation, fine motor development, and cognitive growth while the infant is restricted by the cast. D. Changing diapers promptly is necessary for hygiene and cast protection but does not specifically address growth and development.
