Instructions: This comprehensive 100-question exam aligns with the Sentinel U APS Pediatric Wellness Simulation -
Marci Owens Case requirements at Northern Kentucky University. The exam is organized into eight sections covering
pediatric growth and development, health assessment, wellness and health promotion, pharmacology, common
conditions, family-centered care, clinical decision-making and documentation, and Sentinel U simulation competencies
and debriefing. Each question presents four options (A-D) with one correct answer. Rationales provide pediatric wellness
nursing reasoning, identify why correct options are right and distractors are wrong, and link concepts to Sentinel U
simulation competency standards. Use this exam to confirm mastery and achieve 100% score report preparation on the
Sentinel U APS platform.
Section 1: Pediatric Growth and Development
Q1: Marci Owens, a 4-year-old girl, presents for a well-child visit. Her mother reports she can hop on one
foot, draw a person with three body parts, and use sentences of four to five words. Which statement best
reflects the difference between growth and development in this context?
A. Growth refers to the acquisition of new skills like hopping and drawing, while development refers only to height
and weight changes.
B. Growth refers to measurable physical changes such as height and weight, while development refers to
the sequential acquisition of skills and functions across domains. [CORRECT]
C. Growth and development are interchangeable terms used to describe motor skill acquisition.
D. Growth refers to cognitive milestones only, while development refers to physical size changes.
Correct Answer: B
Rationale: Growth refers to measurable, quantitative physical changes such as height, weight, and head circumference,
whereas development refers to the sequential acquisition of functional skills across cognitive, motor, language, and
social-emotional domains. Marci's hopping, drawing, and sentence use are developmental milestones, not growth
parameters. Confusing growth with development is a common pediatric wellness error. Sentinel U APS expects students to
distinguish these concepts when documenting the Marci Owens case.
Q2: Marci Owens is at the 60th percentile for weight and 55th percentile for height on the CDC growth
chart. Her mother asks what this means. Which response by the nursing student is most accurate?
A. Marci weighs more than 60 children out of 100 of the same age and sex, and is taller than 55 of 100 peers
of the same age and sex. [CORRECT]
B. Marci is 60% of ideal body weight and 55% of ideal height for her age.
C. Marci's weight is 60 kg and her height is 55 inches, adjusted for age.
D. Marci is in the 60th percentile of healthy weight, meaning she is moderately overweight.
Correct Answer: A
Rationale: Percentiles on a growth chart indicate the percentage of children of the same age and sex whose measurements
fall at or below the child's measurement. Marci at the 60th percentile for weight means she weighs more than 60% of
same-age, same-sex peers. Options B, C, and D reflect common pediatric wellness misconceptions about percentile
interpretation. Sentinel U APS scoring rewards accurate caregiver education on growth chart interpretation during the

Marci Owens wellness visit.
Q3: An infant's head circumference is plotted at the 95th percentile at the 2-month, 4-month, and 6-month
visits, with weight and height at the 50th percentile. What is the most appropriate nursing interpretation?
A. This is normal because head circumference should always exceed weight and height percentiles.
B. Disproportionate head circumference relative to weight and height warrants further evaluation for
conditions such as hydrocephalus or macrocephaly; the trend should be reviewed with the provider.
[CORRECT]
C. The infant is overweight and needs dietary restriction.
D. Head circumference percentiles are not clinically useful and can be ignored.
Correct Answer: B
Rationale: A head circumference persistently at the 95th percentile while weight and height track at the 50th percentile is
a disproportionate finding that warrants further evaluation for hydrocephalus, familial macrocephaly, or other intracranial
pathology. Cross-percentile lines or disproportionate measurements require provider notification rather than reassurance.
Sentinel U APS expects students to recognize abnormal growth patterns and escalate findings during the pediatric wellness
assessment.
Q4: When assessing a 6-month-old infant's developmental milestones, which finding should the nursing
student identify as concerning and warranting further evaluation?
A. The infant cannot yet walk independently.
B. The infant does not babble consonant sounds and does not roll from front to back. [CORRECT]
C. The infant cannot yet use a pincer grasp.
D. The infant cannot yet say two-word phrases.
Correct Answer: B
Rationale: By 6 months, infants typically babble consonant sounds and roll from front to back; absence of these milestones
is concerning and warrants further developmental evaluation. Walking independently and using two-word phrases are
12-month and 18-to-24-month milestones, respectively, so their absence at 6 months is not concerning. Pincer grasp
typically emerges around 9 to 12 months. Sentinel U APS expects students to apply age-appropriate milestone criteria
during pediatric assessment.
Q5: Marci Owens is 4 years old. Which developmental milestone is age-appropriate for her cognitive
development according to Piaget's preoperational stage?
A. Abstract hypothetical reasoning about future careers
B. Magical thinking, egocentrism, and symbolic play such as using a banana as a telephone [CORRECT]
C. Concrete logical reasoning about conservation of volume
D. Sensorimotor exploration using only reflexes
Correct Answer: B
Rationale: Piaget's preoperational stage (ages 2 to 7) is characterized by magical thinking, egocentrism, and symbolic play,
such as using a banana as a telephone. Abstract reasoning is a formal operational stage achievement (age 12+), conservation
of volume is a concrete operational milestone (age 7 to 11), and sensorimotor reflexes are seen in infancy (birth to 2 years).
Sentinel U APS expects students to apply developmental theory to age-appropriate assessment of Marci Owens.
Q6: A mother asks when her toddler will be ready for toilet training. Based on developmental readiness,
which age range is most appropriate?
A. 12 to 15 months
B. 18 to 24 months [CORRECT]
C. 30 to 36 months
D. 3 to 4 years
Correct Answer: B

, Sentinel U APS | Pediatric Wellness Simulation - Marci Owens Case Northern Kentucky University | 2026/2027
Rationale: Toilet training readiness typically occurs between 18 and 24 months, when toddlers demonstrate physiological
readiness (longer dry periods), motor readiness (walking, sitting steadily), and cognitive awareness of the need to void.
Starting before 18 months is generally too early physiologically and cognitively. Sentinel U APS expects students to provide
accurate anticipatory guidance during pediatric wellness visits.
Q7: Which screening tool is most appropriate for detecting autism spectrum disorder risk in a toddler at
the 18-month and 24-month well-child visits?
A. Denver II
B. M-CHAT (Modified Checklist for Autism in Toddlers) [CORRECT]
C. Ages and Stages Questionnaire only
D. Snellen chart
Correct Answer: B
Rationale: The M-CHAT is the recommended autism-specific screening tool administered at the 18-month and 24-month
well-child visits to identify autism spectrum disorder risk. Denver II is a general developmental screening tool, the Ages and
Stages Questionnaire screens general development through parent report, and the Snellen chart screens vision. Sentinel U
APS expects students to select the correct screening tool for the appropriate pediatric wellness visit age.
Q8: An adolescent's BMI is plotted at the 88th percentile for age and sex. How should this be categorized
according to CDC pediatric BMI standards?
A. Underweight
B. Healthy weight
C. Overweight [CORRECT]
D. Obese
Correct Answer: C
Rationale: CDC pediatric BMI percentiles define overweight as 85th to less than 95th percentile and obesity as equal to or
greater than 95th percentile. A BMI at the 88th percentile falls in the overweight category. Underweight is less than the 5th
percentile, and healthy weight is 5th to less than 85th percentile. Distinguishing overweight from obese is a common
pediatric wellness confusion point that Sentinel U APS expects students to navigate correctly.
Q9: Marci Owens, age 4, can button her shirt, copy a square, and understand the concept of sharing. Which
Erikson developmental stage is she in, and what is the central task?
A. Trust vs. Mistrust
B. Autonomy vs. Shame and Doubt
C. Initiative vs. Guilt [CORRECT]
D. Industry vs. Inferiority
Correct Answer: C
Rationale: Erikson's Initiative vs. Guilt stage (ages 3 to 6) centers on developing purpose and initiative through play,
exploration, and taking on tasks like dressing and sharing. Trust vs. Mistrust is infancy, Autonomy vs. Shame and Doubt is
toddlerhood (1 to 3 years), and Industry vs. Inferiority is school age (6 to 12 years). Sentinel U APS expects students to
apply Eriksonian theory when interpreting Marci Owens's developmental behaviors.
Q10: A parent asks why the Denver II developmental screening tool is administered. Which response best
describes its purpose?
A. It diagnoses autism spectrum disorder.
B. It is a general developmental screening tool that identifies children who need further evaluation across
personal-social, fine motor, language, and gross motor domains. [CORRECT]
C. It replaces the need for a comprehensive physical examination.
D. It measures intelligence quotient (IQ) in young children.
