👶🏻 Pediatrics: Development I and II (reflex integration, postural reactions)

Question 1

Pediatrics: development

Term babies are born between _______ weeks of gestation

Answer 1

38 and 42

Question 2

Pediatrics: development

calculating the adjusted age of preterm infants

Answer 2

chronological age (in weeks) minus the number of premature weeks

• Chronological age (age from birth): 20 weeks
• The number of weeks your baby was premature: 6 weeks
• Subtract the number of weeks premature from the chronological age (this is your baby’s adjusted age): 20 weeks minus 6 weeks equal 14 weeks.
