Introduction
This comprehensive assessment is designed to evaluate the advanced practice
nursing student's mastery of pediatric primary care and pharmacology as
outlined in MSN 629. The examination measures foundational knowledge in
child development, pathophysiology, pharmacotherapeutics, and the clinical
management of common pediatric conditions. Questions integrate real-world
clinical scenarios, ethical decision-making, and evidence-based practice to
assess the student's readiness for independent primary care practice. The
multiple-choice format challenges critical thinking and application of theory to
practice, ensuring that the student can synthesize complex information and
make sound clinical judgments in the care of children and their families.
,SECTION ONE: QUESTIONS 1–100
Question 1
A 2-year-old child presents with a fever of 102°F, irritability, and tugging at the
right ear. The tympanic membrane is bulging, erythematous, and has
decreased mobility. Which of the following is the most appropriate first-line
pharmacologic management?
A. Amoxicillin 80–90 mg/kg/day divided twice daily
B. Azithromycin 10 mg/kg on day one followed by 5 mg/kg for four days
C. Cefdinir 14 mg/kg/day divided once or twice daily
D. Observation without antibiotics for 48–72 hours
A. Amoxicillin 80–90 mg/kg/day divided twice daily
RATIONALE: Acute otitis media (AOM) in a child with severe symptoms
(fever >102°F, bulging tympanic membrane) warrants antibiotic therapy.
Amoxicillin is the first-line agent due to its efficacy, narrow spectrum, and
safety profile. High-dose amoxicillin (80–90 mg/kg/day) is recommended to
cover Streptococcus pneumoniae with reduced penicillin susceptibility.
Question 2
A 6-month-old infant is brought in for a well-child visit. The parent reports
that the infant has been rolling from back to tummy but cannot roll back.
Which developmental milestone is most appropriate to assess next?
A. Sitting without support
B. Transferring objects from hand to hand
C. Babbling consonant-vowel combinations
D. Pincer grasp
C. Babbling consonant-vowel combinations
RATIONALE: At 6 months, infants typically begin babbling with
consonant-vowel combinations (e.g., "ba-ba," "da-da"). Rolling both ways is
expected by 6 months; the infant has achieved rolling one way. Sitting
without support typically emerges at 7–8 months, transferring objects at 7
,months, and pincer grasp at 9–10 months. The next milestone to assess is
language development.
Question 3
A 4-year-old child with a history of atopic dermatitis develops erythematous,
weeping plaques on the flexural surfaces of the elbows and knees. The parent
reports intense pruritus. Which of the following is the most appropriate
initial pharmacologic intervention?
A. Oral antihistamine and topical calcineurin inhibitor
B. Topical corticosteroids and emollients
C. Systemic corticosteroids and wet wraps
D. Oral antibiotics and antifungal cream
B. Topical corticosteroids and emollients
RATIONALE: Atopic dermatitis exacerbations are managed with topical
corticosteroids to reduce inflammation and emollients to restore skin barrier
function. Topical calcineurin inhibitors are second-line for sensitive areas or
steroid-resistant cases. Systemic corticosteroids are reserved for severe,
refractory cases. Antibiotics are only indicated if secondary infection is
present.
Question 4
A 10-year-old child with asthma presents with a peak expiratory flow rate of
65% of personal best, cough, and mild wheezing. Which step of the asthma
management plan should be initiated?
A. Green zone – continue maintenance therapy
B. Yellow zone – initiate short-acting beta-agonist (SABA) every 4–6 hours
C. Red zone – immediate emergency department referral
D. Yellow zone – increase inhaled corticosteroid dose
B. Yellow zone – initiate short-acting beta-agonist (SABA) every 4–6 hours
RATIONALE: A peak expiratory flow rate of 50–79% of personal best
indicates the yellow zone (caution). The appropriate action is to initiate SABA
, every 4–6 hours and consider adding a short course of oral corticosteroids if
symptoms persist. The green zone (>80%) indicates good control. The red
zone (<50%) requires emergency care.
Question 5
Which of the following vaccines is contraindicated in a child with a known
severe allergy to neomycin?
A. Inactivated polio vaccine (IPV)
B. Measles, mumps, rubella (MMR) vaccine
C. Varicella vaccine
D. Diphtheria, tetanus, acellular pertussis (DTaP) vaccine
A. Inactivated polio vaccine (IPV)
RATIONALE: IPV contains trace amounts of neomycin, streptomycin, and
polymyxin B. A severe allergy to neomycin is a contraindication to IPV. MMR
and varicella vaccines contain neomycin as well but are often administered
with caution; however, IPV is specifically contraindicated. DTaP does not
contain neomycin.
Question 6
A 3-year-old child is diagnosed with iron deficiency anemia. The hemoglobin
is 9.5 g/dL. Which of the following is the most appropriate initial treatment?
A. Ferrous sulfate 3–6 mg/kg/day elemental iron divided twice daily
B. Ferrous sulfate 1–2 mg/kg/day elemental iron once daily
C. Iron dextran intramuscular injection
D. Dietary modification alone with iron-rich foods
A. Ferrous sulfate 3–6 mg/kg/day elemental iron divided twice daily
RATIONALE: The recommended treatment for iron deficiency anemia in
children is elemental iron 3–6 mg/kg/day divided into two or three doses.
This dose ensures adequate repletion of iron stores. Lower doses (1–2
mg/kg/day) are used for prophylaxis. Parenteral iron is reserved for
