ATI Pediatric CMS Comprehensive Examination 2026/2027 | Verified Questions
,INTRODUCTION
This comprehensive examination contains exactly 100 original verified questions designed to reinforce the official
ATI Testing Pediatric Comprehensive Mastery Series (CMS) Examination course objectives for actual exam
readiness and clinical proficiency in the 2026/2027 academic year. The questions span four core domains: Domain
1 Growth and Development, Domain 2 Health Promotion and Maintenance, Domain 3 Pediatric Nursing Care and
Clinical Management, and Domain 4 Safety, Infection Control, and Pharmacological Therapies. Each question is
crafted to test distinct sub-topics drawn from foundational pediatric nursing methodology, enabling university-level
nursing students to demonstrate clinical diagnostic mastery across the pediatric lifespan.
ACTUAL QUESTIONS
Domain 1: Growth and Development
Question 1. According to Erikson, the primary developmental task of a toddler (ages 1–3 years) is:
A. Trust versus mistrust
B. Autonomy versus shame and doubt
C. Initiative versus guilt
D. Industry versus inferiority
Correct Answer: D
Rationale: Erikson’s stage for toddlers is autonomy versus shame and doubt, reflected in the drive for
independence and the emergence of the word “no.”
Question 2. A 6-month-old infant is expected to demonstrate which gross-motor milestone?
A. Sitting without support for extended periods
B. Rolling from back to abdomen and sitting with support
C. Walking with assistance
D. Standing alone briefly
Correct Answer: B
Rationale: By 6 months most infants can roll from supine to prone and sit with support; independent sitting
usually appears closer to 7–8 months.
Question 3. Which fine-motor skill is typically acquired by a 9-month-old infant?
A. Neat pincer grasp
B. Crude pincer grasp (thumb and index finger)
C. Transferring objects from hand to hand only
D. Building a tower of four cubes
Correct Answer: C
Rationale: The crude pincer grasp emerges around 9 months; the neat pincer grasp is usually present by 12
months.
Question 4. Piaget’s sensorimotor stage is characteristic of which age group?
A. Birth to 2 years
B. 2 to 7 years
C. 7 to 11 years
D. 11 years and older
Correct Answer: D
Rationale: The sensorimotor stage (birth to approximately 2 years) is defined by learning through sensory
experiences and motor actions, culminating in object permanence.
Question 5. A 4-year-old child is most likely to engage in which type of play?
A. Solitary play exclusively
B. Parallel play
C. Associative and cooperative play with imaginative themes
D. Competitive team sports with complex rules

A. Speaking in complete sentences of 5–6 words
B. Using approximately 10–20 words and beginning to combine two words
C. Having a vocabulary of more than 200 words
D. Understanding complex multi-step verbal instructions only
Correct Answer: D
Rationale: By 18 months children typically use 10–20 words and may begin combining two words; vocabulary
expands rapidly thereafter.
Question 7. The anterior fontanelle normally closes by which age?
A. 2–3 months
B. 6–8 months
C. 12–18 months
D. 24–36 months
Correct Answer: A
Rationale: The anterior fontanelle closes between 12 and 18 months of age; persistent openness beyond this range
warrants evaluation.
Question 8. According to Kohlberg, a school-age child who follows rules to avoid punishment is
operating at which level of moral development?
A. Postconventional
B. Conventional
C. Preconventional
D. Autonomous
Correct Answer: C
Rationale: Preconventional morality is characterized by obedience based on avoidance of punishment or desire
for reward and is typical of younger school-age children.
Question 9. A 2-year-old who cannot yet hop on one foot or draw a circle is most likely
demonstrating:
A. Advanced fine-motor skills
B. Age-appropriate gross- and fine-motor development
C. Significant developmental delay requiring immediate referral
D. Precocious puberty
Correct Answer: D
Rationale: Hopping and drawing a circle are milestones expected closer to 4 years; a 2-year-old is not expected to
perform them.

Erikson?
A. Developing a sense of industry through school achievement
B. Exploring initiative through imaginative play and goal-directed activity

A. Preoperational
B. Sensorimotor
C. Concrete operational
D. Formal operational
