A pediatric clinic is implementing a new screening tool for early childhood development. The nursing staff is tasked with organizing a chronological checklist of expected developmental milestones to evaluate pediatric patients over their first three years of life. Arrange the following sets of developmental milestones in chronological order from the earliest expected age of acquisition to the latest.
- 1Displays a social smile and tracks objects visually past the midline
- 2Sits independently without support and transfers objects from hand to hand
- 3Utilizes a mature pincer grasp and stands alone independently
- 4Combines words into two-word phrases and walks up stairs with both feet on each step
- 5Copies a drawn circle and pedals a tricycle
Cevap
The milestones should be sequenced chronologically by age of acquisition: 2 months, 6 months, 12 months, 24 months, and 36 months.
Normal pediatric development occurs in a predictable chronological sequence. Early infancy (2 months) is characterized by the social smile and visual tracking. By 6 months, infants gain truncal control to sit independently and can transfer objects between hands. Around 12 months, infants pull to stand, stand independently, and develop a mature pincer grasp using the thumb and index finger. At 24 months, expressive language progresses to two-word phrases, and children can walk up stairs placing both feet on each step. By 36 months, fine and gross motor skills advance to copying a circle and pedaling a tricycle.
