A nurse is caring for a 12-month-old toddler who is hospitalized and confined to a room with contact precautions in place. Which of the following toys would be best for the nurse to recommend in order to meet the developmental needs of the client?

The correct answer is D: Large building blocks. At 12 months, toddlers are in the sensorimotor stage of development, where they explore objects through touch and manipulation. Large building blocks allow the toddler to practice fine motor skills, hand-eye coordination, and spatial awareness. They also promote creativity and problem-solving. Crayons and coloring books (choice A) are more suitable for older children who have developed better fine motor skills. Modeling clay (choice B) may pose a choking hazard for a 12-month-old. Hanging crib toys (choice C) are more appropriate for infants and may not provide enough stimulation for a toddler.
