Chapter 1: The Newborn Infant
Current Diagnosis & Treatment Pediatrics, 27th Edition
Test Bank – Multiple Choice with Rationales

1. Developmental Milestones
Question:
When the nurse pulls a 2-month-old infant from a supine to a sitting position, which response is developmentally
appropriate?
A. Complete head lag occurs throughout the maneuver
B. The infant fully supports the head in a straight line
C. The infant briefly holds the head erect
D. The infant demonstrates no head lag
Correct Answer: C
Rationale:
At 2 months of age, infants can briefly hold the head erect but still demonstrate some head lag. Full head control typically
develops around 4 months of age.
• A describes a younger newborn
• B and D describe development seen closer to 4 months

2. Growth and Weight Gain
Question:
A newborn weighs 7 lb 6 oz at birth. What should the infant weigh at approximately 1 year of age?
A. 14 lb 12 oz
B. 22 lb 2 oz
C. 29 lb 8 oz
D. Weight cannot be estimated
Correct Answer: B
Rationale:
Infants typically triple their birth weight by 1 year of age.
• Double birth weight: ~6 months
• Triple birth weight: ~12 months
• Quadruple birth weight: ~2 years

3. Developmental Delay
Question:
Which parental statement is most consistent with a possible developmental delay?
A. “My 9-month-old responds to his name.”
B. “My 12-month-old cannot sit independently or pull to stand.”
C. “My 6-week-old smiles at me.”
D. “My 5-month-old is not rolling both ways yet.”
Correct Answer: B
Rationale:
By 12 months, infants should be able to sit independently, pull to stand, and often stand briefly. Failure to achieve these
milestones suggests developmental delay.
• A, C, and D describe age-appropriate development

4. Immunizations at 2 Months
Question:
Which immunizations should a healthy 2-month-old infant receive?
A. DTaP, IPV, HepB, Hib, PCV, rotavirus
B. MMR, DTaP, PCV, IPV
C. Hib, DTaP, OPV, rotavirus
D. Hib, MMR, IPV, rotavirus

Correct Answer: A
Rationale:
At 2 months, infants receive DTaP, IPV, HepB, Hib, PCV, and rotavirus.
• MMR is not given until ≥12 months
• OPV is no longer used in the U.S.

5. Nutrition: Breastfeeding
Question:
What should the nurse advise a mother of a 3-month-old infant who is exclusively breastfed?
A. Begin vitamin D supplementation
B. Add rice cereal to formula
C. Introduce spoon-fed rice cereal
D. Continue breastfeeding without supplements
Correct Answer: A
Rationale:
Breast milk does not provide sufficient vitamin D. Exclusively breastfed infants require vitamin D supplementation to
prevent rickets.
• Solid foods are not recommended before 4–6 months

6. Object Permanence
Question:
At what age should an infant first be expected to search for a hidden object?
A. 4 months
B. 6 months
C. 9 months
D. 20 months
Correct Answer: C
Rationale:
Object permanence develops around 9 months. At this age, infants actively search for objects hidden from view.
• Younger infants lack cognitive awareness of object permanence

7. Vaccine Hesitancy
Question:
Parents state they plan not to immunize their newborn because of fear of injury. What is the nurse’s best response?
A. “That is your decision.”
B. “Have you discussed this with grandparents?”
C. “The risks of not immunizing are greater than the risks of vaccines.”
D. “You are making a mistake.”
Correct Answer: C
Rationale:
Nurses have a responsibility to provide evidence-based education. While rare adverse events occur, the risk of serious
disease from lack of immunization is significantly higher.
• Judgmental responses are inappropriate

8. Separation Anxiety
Question:
A mother reports her 9-month-old cries when she leaves the room. What is the best nursing response?
A. Encourage leaving the infant more often
B. Suggest a medical evaluation
C. Ask about teething
D. Explain this is a normal sign of attachment
Correct Answer: D
Rationale:
Separation and stranger anxiety are normal developmental findings in late infancy and indicate healthy attachment.
