Zorluk: OrtaPreventive Care and Immunizations

During routine pediatric well-child examinations, clinicians assess the acquisition of appropriate developmental milestones to ensure normal neurologic maturation. Arrange the following gross motor milestones in the chronological order in which they are typically achieved by a healthy, term, neurotypically developing child.

  1. 1Lifting the head and chest while in a prone position
  2. 2Sitting independently without hand support
  3. 3Cruising along furniture
  4. 4Walking up stairs with both feet on each step
  5. 5Pedaling a tricycle

Cevap

The correct chronological sequence of gross motor milestone acquisition is: lifting the head and chest in prone (2 months), sitting independently without support (6 months), cruising along furniture (9 months), walking up stairs with both feet on each step (24 months), and pedaling a tricycle (36 months).
Normal gross motor development follows a predictable cephalocaudal progression. The sequence begins with cervical muscle control (lifting head at 2 months), progresses to truncal stability (sitting unsupported at 6 months), moves to lower extremity weight-bearing and assisted mobility (cruising at 9 months), and finally advances to complex dynamic balance and coordination (walking stairs with both feet per step at 2 years, and pedaling a tricycle at 3 years).

Adım Adım Çözüm

1
Identify the earliest infant milestone in the sequence.
Lifting the head and chest while in a prone position is placed first.
Gross motor development progresses in a cephalocaudal (head-to-toe) direction. Head control is the earliest major gross motor milestone, achieved at 2 months.
2
Identify the milestone related to truncal stability.
Sitting independently without hand support is placed second.
By 6 months, infants gain sufficient core truncal tone to sit completely unassisted.
3
Identify the milestone related to initial weight-bearing and upright mobility.
Cruising along furniture is placed third.
By 9 months, infants can pull to a stand and begin taking side-steps while holding onto furniture (cruising).
4
Identify the early toddler milestone requiring basic balance.
Walking up stairs with both feet on each step is placed fourth.
By 24 months (2 years), toddlers can navigate stairs, though they still place both feet on each step rather than alternating feet.
5
Identify the most advanced preschool milestone in the sequence.
Pedaling a tricycle is placed last.
By 36 months (3 years), children develop the complex bilateral coordination required to pedal a tricycle.

Normal gross motor developmental milestones progress cephalocaudally, starting with head control and advancing through sitting, walking, and complex coordination.
