The nursing instructor is conducting a class on the development of an infant. The instructor determines the class is successful when the students correctly illustrate which as the proximodistal development in an infant?

Choice A reason: Walking then running is a gross motor sequence, not proximodistal, which progresses from central to peripheral control. Arm waving to foot grasping shows this pattern, making this incorrect, as it does not illustrate the infant’s proximodistal development in the instructor’s class. Choice B reason: Rolling over precedes eye tracking, but proximodistal development involves motor control from trunk to extremities. Arm waving to foot grasping better illustrates this, making this incorrect, as it does not reflect the central-to-peripheral progression of infant motor development in the lesson. Choice C reason: Imitating sounds to speaking is linguistic, not proximodistal, which focuses on motor control from core to limbs. Arm waving to foot grasping demonstrates this pattern, making this incorrect, as it does not represent the physical developmental sequence taught in the infant development class. Choice D reason: Kicking and arm waving involve trunk and proximal muscles, while grasping the foot uses distal control, illustrating proximodistal development. Students choosing this show understanding, aligning with infant motor development principles, making it the correct example for a successful class on infant development.
