nursing core concepts including growth and development milestones, common childhood
conditions, emergency interventions, and nursing care priorities .
SECTION 1: GROWTH AND DEVELOPMENT MILESTONES
Q1. Which is the best method for a nurse to perform a physical assessment on an 18-month-
old toddler?
A) Head-to-toe approach
B) Least to most invasive
C) Most invasive to least invasive
D) Focused assessment only
Answer: B) Least to most invasive
Rationale: For toddlers, the best approach is least to most invasive. Begin with less threatening
procedures (observation, auscultation) before progressing to more invasive assessments (ear
exam, throat swab). This builds trust and reduces anxiety .
Q2. At what age should children be able to sit unsupported?
,A) 2-3 months
B) 3-4 months
C) 5-6 months
D) 7-8 months
Answer: B) 3-4 months
Rationale: Most infants can sit unsupported by 3-4 months of age. By 6 months, they should be
able to sit upright alone .
Q3. At what age should babies first start eating solid foods?
A) 4 months
B) 5 months
C) 6 months
D) 8 months
Answer: C) 6 months
Rationale: The American Academy of Pediatrics recommends introducing solid foods at
approximately 6 months of age, starting with iron-fortified rice cereal mixed with formula or
breast milk .

old infant?

B) Child rolls from side to side
C) Child is able to lift head
D) Rooting reflex has disappeared
Answer: A) Anterior fontanel is closed
Rationale: The anterior fontanel typically closes between 12-18 months. Closure at 5 months is
a concerning finding that should be reported to the provider .

the provider?
, A) Birth length has increased by 50%
B) 8 teeth have erupted
C) Birth weight has doubled

intervention consult would be indicated for which of the following findings? Select all that
apply.
A) Pincer grasp
B) Head lag

D) Stranger anxiety
Answer: B) Head lag; C) Does not roll over
Rationale: By 7 months, infants should have no head lag and should be able to roll over. Pincer
grasp and stranger anxiety are expected milestones at this age. Failure to meet these milestones
warrants early intervention referral .

A) Sitting upright and walking
B) Lifting belly up and pushing themselves up with arms
C) Pincer grasp and crawling
D) Rolling over and sitting alone
Answer: B) Lifting belly up and pushing themselves up with arms
