Zorluk: KolayPreventive Care and Immunizations

A medical student is reviewing normal gross motor developmental milestones in preparation for performing routine well-child screening examinations. Arrange the following gross motor milestones in the chronological order they typically appear in a healthy infant.

  1. 1Rolls from prone to supine
  2. 2Sits momentarily without support
  3. 3Pulls to stand
  4. 4Walks independently

Cevap

The correct chronological sequence of gross motor development is: rolling from prone to supine, sitting momentarily without support, pulling to stand, and finally walking independently.
Gross motor development progresses in a predictable cephalocaudal (head-to-toe) direction. An infant typically learns to roll from prone to supine at 4 months, sits unsupported at 6 months, pulls to a standing position at 9 months, and walks independently by 12 to 15 months.

Adım Adım Çözüm

1
Determine the typical age for rolling from prone to supine.
Typically occurs at 4 months of age.
This early milestone requires head and upper trunk control.
2
Determine the typical age for sitting without support.
Typically occurs at 6 months of age.
This requires further development of core truncal stability.
3
Determine the typical age for pulling to stand.
Typically occurs at 9 months of age.
This requires lower extremity strength and coordination.
4
Determine the typical age for walking independently.
Typically occurs at 12 to 15 months of age.
This is the culmination of infant gross motor development requiring full balance and coordination.
5
Arrange the milestones sequentially by age.
The order is 4 months, 6 months, 9 months, and 12-15 months.
Developmental milestones follow a predictable chronological and cephalocaudal progression.
