The nurse in a pediatrician's office is preparing to do a developmental assessment on a 3-month-old infant who was born at 36 weeks. The nurse knows that the infant should be evaluated in what month of achievement to adjust for the preterm birth?

A. 2nd: For infants born preterm, developmental assessments are adjusted based on the corrected age, which accounts for the number of weeks the infant was born early. A 3-month-old infant born at 36 weeks (4 weeks early) would be evaluated as a 2-month-old to accurately reflect expected developmental milestones. B. 4th: Using the chronological age of 3 months without adjustment would overestimate the infant’s developmental progress. Evaluating as 4 months would not be appropriate for correcting preterm birth. C. 1st: Assessing the infant as 1 month old would underestimate developmental abilities, potentially missing delays or issues that are appropriate for corrected age. D. 3rd: Evaluating a preterm infant using chronological age alone does not account for early birth. At 3 months chronological age, the infant’s corrected age is 2 months, which should guide the assessment for milestone achievement.
