MSN 629 Pediatric Primary Care & Pharmacology
Advanced Pediatric Nursing Practice Exam 2026–
2027 | Comprehensive Pediatric Nursing Practice
Questions with Verified Answers & Detailed
Rationales | Advanced Pediatric Care &
Pharmacology Exam Preparation
Description:
This comprehensive examination is designed to assess the knowledge
and clinical reasoning skills of nurse practitioner students in the
primary care of children. It integrates principles of child development,
pathophysiology, pharmacology, and evidence-based practice as
applied to common pediatric health problems. This exam aligns with
the official syllabus for MSN 629, focusing on clinical management,
diagnostic reasoning, pharmacologic interventions, and health
promotion for pediatric patients from infancy through adolescence.
The scenario-based questions are designed to test recall, application,
and critical decision-making expected of a competent primary care
provider. The content reflects the structure of Sentinel U Advanced
Practice Series (APS) simulations, which are mapped to NONPF
Nurse Practitioner Core Competencies and focus on identifying
diagnoses, organizing plans of care, and appropriate coding.
MSN 629 Week 3 Quiz
Section 1 Questions 1 to 50
1. A 4 year old child like Alonzo should be able to accomplish which
fine motor skill
A. Tying shoelaces
B. Drawing a circle
C. Using safety scissors
D. Writing first name
Correct Answer: B
,2|Page
Rationale: Drawing a circle is an age appropriate fine motor milestone
for a 4 year old. Tying shoelaces typically emerges at age 6, using
safety scissors at age 5, and writing a first name at age 5 to 6.
2. A child speaks in 4 to 5 word sentences and asks why questions
constantly. This language development is typical for which age
A. 2 years
B. 3 years
C. 4 years
D. 5 years
Correct Answer: C
Rationale: Four year olds typically use 4 to 5 word sentences, ask
many questions especially why, and can tell simple stories. Two year
olds use 2 to 3 word phrases, three year olds use 3 to 4 word
sentences.
3. Which gross motor milestone is expected in a typically developing
4 year old
A. Hopping on one foot
B. Skipping
C. Walking backward
D. Standing on tiptoes
Correct Answer: A
Rationale: Hopping on one foot emerges at age 4. Skipping develops
at age 5. Walking backward is a 3 year old skill. Standing on tiptoes is
a 2 to 3 year skill.
4. A 4 year olds play behavior is typically described as
A. Solitary
B. Associative and cooperative
C. Parallel
D. Onlooker
Correct Answer: B
Rationale: Associative and cooperative play with peers emerges at age
4. Solitary and parallel play are typical for toddlers. Onlooker play is
also seen in younger children.

5. Which Piaget stage corresponds to a 4 year old child
A. Sensorimotor
B. Preoperational
C. Concrete operational
D. Formal operational
Correct Answer: B
Rationale: Piagets preoperational stage ages 2 to 7 is characterized by
egocentrism, magical thinking, and symbolic play. Sensorimotor is
birth to 2 years, concrete operational is 7 to 11 years, and formal
operational is 11 years and older.
6. Red flags for developmental delay at age 4 include all except
A. Unable to copy a circle
B. Does not use me and you correctly
C. Can brush teeth with help
D. No interest in interactive games
Correct Answer: C
Rationale: Brushing teeth with help is appropriate for age 4. The other
options represent developmental red flags requiring further
evaluation.
7. Which developmental screening tool is most appropriate for a
wellness visit in a 4 year old
A. M-CHAT
B. Denver II
C. PHQ-9
D. CAGE questionnaire
Correct Answer: B
Rationale: The Denver II screens personal social, fine motor adaptive,
language, and gross motor domains. M-CHAT is for toddlers 16 to 30
months. PHQ-9 and CAGE are for mental health and substance use in
older patients.
8. The Moro startle reflex typically disappears in a healthy infant at
what age
A. 1 to 2 months
B. 3 to 4 months
, 4|Page
C. 5 to 6 months
D. 7 to 8 months
Correct Answer: B
Rationale: The Moro reflex typically disappears by 3 to 4 months of
age. Persistence beyond this age may indicate a neurologic issue.
9. A mother brings her 6 month old infant to the clinic with a rash.
She reports the infant has been excessively fussy and scratching. The
rash is erythematous, weeping, and has small vesicles on the cheeks
and extensor surfaces. What is the most likely diagnosis
A. Seborrheic dermatitis
B. Allergic contact dermatitis
C. Atopic dermatitis acute phase
D. Irritant contact dermatitis
Correct Answer: C
Rationale: The presentation of an erythematous, pruritic, weeping,
vesicular rash on the cheeks and extensor surfaces in an infant is
characteristic of the acute phase of atopic dermatitis. Atopic
dermatitis is a common inflammatory skin disorder in children and
the acute phase presents with vesicles and weeping lesions.
10. A 4 week old infant is brought in for a well child visit. On
examination you note a small tuft of hair over the lumbosacral spine.
This finding is most concerning for which of the following underlying
conditions
A. Neurofibromatosis type 1
B. Tuberous sclerosis
C. Spina bifida occulta
D. Klippel Trenaunay Weber syndrome
Correct Answer: C
Rationale: A faun tail nevus, or a tuft of hair over the lumbosacral
spine, is a cutaneous marker that can be associated with spina bifida
occulta, a neural tube closure defect. While cafe au lait macules are
associated with neurofibromatosis, a faun tail nevus is specifically
linked to underlying spinal dysraphism.
