Pediatric Nurse Exam Pediatric Nurse Growth and Development Milestones 3 — Questions and Answers
Question 1: According to Piaget, what cognitive stage is a 7-year-old child in?
- Sensorimotor
- Preoperational
- Concrete operational (Correct answer)
- Formal operational
Correct answer: Concrete operational
Children ages 7–11 are in Piaget's concrete operational stage, during which they develop logical thinking about concrete objects.
Question 2: A 15-month-old uses 3–5 words and walks independently. Which additional milestone would be expected at this age?
- Runs well
- Uses a spoon alone
- Says 'mama' and 'dada' specifically (Correct answer)
- Climbs stairs alternating feet
Correct answer: Says 'mama' and 'dada' specifically
By 12–15 months, infants typically say 'mama' and 'dada' with meaning in addition to a few other words.
Question 3: An infant demonstrates object permanence. What is the earliest age this concept typically emerges?
- 2 months
- 4 months
- 8 months (Correct answer)
- 12 months
Correct answer: 8 months
Object permanence begins to emerge around 8–9 months, when infants understand that objects still exist when out of sight.
Question 4: Which weight milestone is expected for a full-term infant by 6 months of age?
- Doubles birth weight (Correct answer)
- Triples birth weight
- Gains 1 pound per month
- Reaches 10 kg
Correct answer: Doubles birth weight
Infants are expected to double their birth weight by approximately 4–6 months of age.
Question 5: A nurse is assessing a 3-year-old who plays alongside but not with other children. What type of play is this?
- Cooperative play
- Parallel play (Correct answer)
- Solitary play
- Associative play
Correct answer: Parallel play
Parallel play, in which children play near each other without direct interaction, is typical of toddlers and early preschoolers.
Question 6: What is the expected head circumference growth rate during the first year of life?
- 1 cm per month for 12 months
- 2 cm per month for 3 months, then 1 cm per month
- 0.5 cm per month throughout
- Rapid in first 6 months, then slows (Correct answer)
Correct answer: Rapid in first 6 months, then slows
Head circumference grows rapidly in the first 6 months (~1.5 cm/month) and then slows to about 0.5 cm/month in the second 6 months.
Question 7: A school-age child understands that the volume of water remains the same when poured into a different-shaped container. Which Piagetian concept does this demonstrate?
- Egocentrism
- Conservation (Correct answer)
- Animism
- Centration
Correct answer: Conservation
Conservation is the understanding that quantity stays the same despite changes in shape or arrangement, mastered in the concrete operational stage.
