Introduction:
The purpose of this comprehensive NSG 542 Pediatric Primary Care
examination guide is to thoroughly evaluate advanced practice nursing
competencies in caring for infants, children, and adolescents. This
assessment measures essential clinical skills and theoretical knowledge
required for comprehensive health promotion, disease prevention,
differential diagnosis, and evidence-based management in outpatient
settings. Featuring a rigorous mix of multiple-choice and complex
scenario-based items, the assessment emphasizes real-world clinical
application, critical thinking, and advanced decision-making. Clinicians
will be tested on their ability to synthesize developmental milestones,
interpret diagnostic data, apply current clinical guidelines, and navigate
intricate ethical and regulatory frameworks inherent to pediatric advanced
practice nursing.
A 4-month-old infant is brought to the clinic for a routine well-child
visit. The mother expresses concern that the infant does not yet roll
over from front to back. Which response by the pediatric nurse
practitioner is most appropriate?
A. Order an immediate neurological consultation and developmental
screening.
B. Reassure the mother, as rolling from front to back is typically expected
around 5 to 6 months of age.
C. Advise immediate physical therapy to improve core muscle tone and
strength.
D. Recommend the mother place the infant in a prone position for
sleeping to accelerate motor milestones.
,🟢 B. Reassure the mother, as rolling from front to back is typically
expected around 5 to 6 months of age.
🔴 Explanation: Developmentally, infants typically achieve rolling from
front to back around 5 to 6 months of age, whereas rolling from back to
front usually occurs slightly later, around 6 months. At 4 months, rolling
over is not a universal milestone, so anticipatory guidance and
reassurance are appropriate rather than immediate referral. Safe sleep
guidelines mandate supine positioning only.
A 2-year-old child presents with a 2-day history of high fever, barking
cough, and stridor that worsens at night. Physical examination
reveals mild intercostal retractions and clear lung fields. What is the
most appropriate initial pharmacological intervention?
A. Oral azithromycin
B. Inhaled albuterol nebulization
C. Single dose of oral dexamethasone
D. Intravenous broad-spectrum antibiotics
🟢 C. Single dose of oral dexamethasone
🔴 Explanation: This presentation is classic for viral croup
(laryngotracheobronchitis). A single dose of oral corticosteroid, such as
dexamethasone, is the cornerstone of management to reduce laryngeal
edema. Antibiotics and albuterol are ineffective since the etiology is
predominantly viral, and invasive interventions are unnecessary for mild
to moderate cases.
An 8-year-old child is diagnosed with attention-deficit/hyperactivity
disorder (ADHD), combined presentation, and treatment with a
central nervous system stimulant is initiated. Which baseline
parameter must the pediatric nurse practitioner document prior to
starting therapy?
A. Liver function panels and serum creatinine
B. Height, weight, blood pressure, and heart rate
C. Complete blood count with differential and fasting lipid panel
D. Electroencephalogram and thyroid stimulating hormone
🟢 B. Height, weight, blood pressure, and heart rate
🔴 Explanation: Stimulant medications (such as methylphenidate or
amphetamines) can cause side effects including decreased appetite,
weight loss, growth suppression, and elevations in heart rate and blood
pressure. Baseline measurements of height, weight, blood pressure, and
,heart rate are mandatory prior to initiation and must be monitored
regularly during follow-up visits.
A 15-year-old female adolescent requests confidential reproductive
health counseling and oral contraceptive pills. Under the legal
doctrine of the mature minor and state-specific minor consent laws,
what is the most appropriate legal and clinical action for the nurse
practitioner?
A. Refuse treatment and mandate that a legal guardian be present to
authorize any prescription.
B. Provide confidential care and prescribe contraception in accordance
with minor consent laws protecting adolescent reproductive health.
C. Provide the counseling but notify the parents immediately via certified
mail regardless of adolescent consent laws.
D. Disclose all diagnostic and treatment records to the school nurse to
ensure institutional compliance.
🟢 B. Provide confidential care and prescribe contraception in
accordance with minor consent laws protecting adolescent reproductive
health.
🔴 Explanation: Most jurisdictions allow minors to independently consent
to reproductive health services, sexually transmitted infection testing, and
contraceptive care without parental notification to encourage early
treatment and reduce public health risks. Respecting confidentiality within
legal boundaries fosters trust and adherence in adolescent care.
A 6-week-old exclusively breastfed infant is brought in for a 2-week
history of worsening projectile, non-bilious vomiting immediately
following feedings. The infant appears hungry after vomiting.
Palpation of the abdomen is most likely to reveal which
characteristic finding?
A. A soft, non-tender abdomen with diffuse tenderness upon deep
palpation
B. A firm, mobile, olive-shaped mass in the right upper quadrant
C. A distended, tympanitic lower left quadrant with palpable stool
D. Marked hepatosplenomegaly extending 4 centimeters below the costal
margin
🟢 B. A firm, mobile, olive-shaped mass in the right upper quadrant
🔴 Explanation: These clinical features are classic for infantile
hypertrophic pyloric stenosis. The obstruction of the gastric outlet leads to
postprandial projectile non-bilious vomiting and metabolic alkalosis.
, Pathognomonic physical exam findings include a palpable, firm, mobile,
olive-shaped mass in the right upper quadrant.
An 18-month-old toddler presents for a routine evaluation. The
parent notes the child communicates using single words only and
points to desired objects instead of speaking phrases. What is the
appropriate developmental assessment and guidance?
A. Refer the child immediately to speech-language pathology for
suspected global developmental delay.
B. Reassure the parent that a vocabulary of several single words and
gesturing is within normal limits for an 18-month-old.
C. Diagnose expressive language disorder and initiate immediate
pharmaceutical treatment.
D. Advise total restriction of all media exposure and reassess at the age
of three years.
🟢 B. Reassure the parent that a vocabulary of several single words and
gesturing is within normal limits for an 18-month-old.
🔴 Explanation: By 18 months of age, children typically have a
vocabulary of approximately 10 to 25 words or more and frequently use
gestures. Using single words and pointing to communicate is
developmentally appropriate. Two-word phrases are generally expected
around 24 months of age.
A 10-year-old boy presents with a 3-day history of sore throat, fever
of 38.8°C, tender anterior cervical lymphadenopathy, and patchy
tonsillar exudates, without cough or rhinorrhea. What is the most
appropriate initial diagnostic step?
A. Immediate supportive care without diagnostic testing
B. Throat culture or rapid antigen detection test (RADT) for group A beta-
hemolytic streptococcus
C. Chest radiography and complete blood count with differential
D. Empiric broad-spectrum intravenous antibiotic therapy
🟢 B. Throat culture or rapid antigen detection test (RADT) for group A
beta-hemolytic streptococcus
🔴 Explanation: The patient's clinical presentation meets several Centor
criteria for streptococcal pharyngitis (fever, tender anterior cervical nodes,
tonsillar exudates, absence of cough). Clinical diagnosis alone is
insufficient; confirmation via rapid streptococcal antigen detection test or
throat culture is required prior to initiating antibiotic therapy to prevent
acute rheumatic fever.
