Match each pediatric patient's clinical presentation with the most appropriate next step in management.
- A 10-month-old infant cannot sit unsupported. A startle response is triggered upon sudden posterior head drop. The infant consistently grasps toys exclusively with the left hand, keeping the right hand fisted.Perform neuroimaging to evaluate for structural brain abnormalities
- A 16-month-old toddler cruises along furniture and stands alone briefly, but has not taken independent steps. He uses a neat pincer grasp, speaks five recognizable words, and points to share interest.Provide anticipatory guidance as this falls within normal developmental variation
- A 30-month-old toddler frequently trips and uses his hands to push against his thighs when rising from the floor. He builds an 8-block tower and speaks in three-word sentences.Obtain serum muscle enzyme analysis
- A 24-month-old toddler engages in complex pretend play, kicks a ball, and follows single-step commands that include a gesture. He uses only four distinct single words and no phrases.Order behavioral or objective assessment of hearing thresholds
Cevap
The correct matches pair the 10-month-old with persistent Moro and early handedness to neuroimaging; the 16-month-old late walker to anticipatory guidance; the 30-month-old with Gowers sign to muscle enzyme analysis; and the 24-month-old with isolated language delay to hearing assessment.
Each presentation requires interpreting a constellation of milestones to determine if a delay is an expected normal variant or a pathological red flag requiring a targeted workup. Early handedness indicates focal neurologic injury requiring neuroimaging; late walking up to 18 months without other delays is normal; Gowers sign indicates proximal myopathy requiring muscle enzymes; and isolated language delay necessitates ruling out hearing loss.

Anahtar Kavram
Differentiating normal developmental variation from red flags requiring specific diagnostic workup (e.g., MRI for early handedness, audiometry for isolated speech delay, CK for Gowers sign).
