Q1: A 4-month-old infant presents for a well-child visit. The mother reports the
baby has been fussy and refuses to take a bottle. On examination, the anterior
fontanelle is bulging when the infant is calm and upright, and there is poor
capillary refill (4 seconds). Which of the following represents the most appropriate
advanced practice nursing action?
A. Reassure the mother that fontanelle bulging is normal during crying and schedule a
2-month follow-up visit.
B. Document the finding as a variant of normal since the posterior fontanelle typically closes
by 6-8 weeks of age.
C. Initiate an expedited sepsis evaluation including CBC, urinalysis, blood culture,
and CSF analysis, with empiric IV antibiotics. **[CORRECT]**
D. Recommend oral acetaminophen and observe at home for 24 hours, returning if fever
develops.
Correct Answer: C
Rationale: A bulging fontanelle in a calm, upright infant with poor capillary refill is a red-flag
finding suggesting increased intracranial pressure or serious bacterial illness, including
meningitis. The advanced practice nurse must recognize that infants less than 90 days (and
up to 6 months) with concerning clinical findings warrant expedited sepsis workup per AAP
guidelines, including empiric antibiotics while awaiting cultures. Options A, B, and D represent
dangerous delays that fail to address the possibility of life-threatening infection; reassurance
is inappropriate when red flags are present, and home observation risks rapid clinical
deterioration.
Q2: During a routine 18-month well-child visit, the parents express concern that
their toddler is not yet using two-word phrases and avoids eye contact. The
Denver II developmental screening reveals delays in language and personal-social
domains. Which action best reflects graduate-level advanced practice nursing
clinical judgment?
A. Reassure the parents that expressive language delay is common in boys and re-evaluate
at the 24-month visit.
B. Refer for audiological evaluation, speech-language assessment, and
developmental pediatrics for autism spectrum disorder screening using
M-CHAT-R. **[CORRECT]**
C. Recommend that parents speak exclusively to the child in short sentences and limit
screen time, then re-screen in 6 months.
D. Order a brain MRI and refer to pediatric neurology to rule out structural abnormalities.
Correct Answer: B
Rationale: Combined language delay, social-communication concerns, and reduced eye
contact at 18 months meet criteria for autism-specific screening via M-CHAT-R per AAP Bright
Futures guidelines, with simultaneous referral for audiological evaluation (rule out hearing
impairment as contributor) and early intervention services. Boys are overrepresented in
developmental disorders, but sex is not a rationale for delayed workup. MRI without focal
neurologic findings is inappropriate as a first-line diagnostic study. Watchful waiting at this
age forfeits the critical early intervention window (0-3 years) when neuroplasticity is greatest.

Q3: A 15-year-old female presents for a sports pre-participation examination. She
is sexually active with one male partner and uses no contraception. When the
parent steps out of the room, she discloses occasional episodes of binge drinking.
Which approach best demonstrates developmentally appropriate adolescent
health assessment?
A. Conduct the interview with the parent present to ensure accurate information and involve
them in any safety planning.
B. Use the HEEADSSS framework in a confidential setting, counsel on
contraception and STI prevention, and offer long-acting reversible
contraception (LARC) options. **[CORRECT]**
C. Notify the parents of the alcohol use as mandated by state law and refer to substance
abuse counseling.
D. Limit the discussion to musculoskeletal screening since this is a sports physical, and defer
behavioral health screening to the primary care provider.
Correct Answer: B
Rationale: The HEEADSSS (Home, Education/Employment, Eating, Activities, Drugs,
Sexuality, Suicide/Depression, Safety) psychosocial interview is the gold standard for
adolescent assessment and must be conducted confidentially after confirming limits of
confidentiality with both adolescent and parent. LARC methods (IUD, implant) are first-line for
adolescents per ACOG due to highest typical-use efficacy. Sports physicals offer a critical
opportunity for comprehensive adolescent screening; reducing it to musculoskeletal exam
alone misses a vital intervention window. Mandatory reporting applies only to abuse, neglect,
or imminent harm, not consensual adolescent behavior.
Q4: A 7-year-old child is brought in for vision screening. The child reads 20/40 on
the Snellen chart with the right eye and 20/20 with the left eye, but corrects to
20/20 with pinhole testing of the right eye. What is the most appropriate next step
in management?
A. Refer to pediatric ophthalmology within 1-2 weeks for comprehensive
evaluation including cycloplegic refraction. **[CORRECT]**
B. Re-screen in 6 months as visual acuity fluctuates in school-age children and pinhole
correction suggests refractive error only.
C. Recommend over-the-counter reading glasses and re-evaluate at the next well-child visit.
D. Order a brain MRI to rule out optic pathway glioma given the asymmetric visual acuity.
Correct Answer: A
Rationale: Asymmetric visual acuity (two-line difference between eyes) in a school-age child
meets criteria for amblyopia risk and warrants prompt referral to pediatric ophthalmology per
AAP and AAPOS guidelines. Pinhole correction confirms refractive error rather than organic
pathology, but untreated asymmetric refractive error can lead to permanent amblyopic vision
loss during the critical visual development period (before age 9-10). Re-screening delays
intervention during this window. MRI is not indicated absent neurologic findings or visual field
defects. OTC glasses without proper refraction can worsen the imbalance.

Q5: A 13-year-old female presents for a routine well-adolescent visit. On physical
examination, breast development shows breast buds with elevation of papilla and
areola (Tanner stage 2), and pubic hair is sparse, lightly pigmented along the labia
(Tanner stage 2). Menarche has not yet occurred. The mother asks if this
development is normal. Which response reflects accurate advanced practice
assessment?
A. Refer to pediatric endocrinology for evaluation of delayed puberty since menarche should
have occurred by this age.
B. Reassure that the findings are consistent with normal pubertal progression;
menarche typically follows thelarche by 2-2.5 years. **[CORRECT]**
C. Order baseline FSH, LH, and estradiol levels to evaluate for primary ovarian insufficiency.
D. Initiate workup for Turner syndrome given the absence of menarche at age 13.
Correct Answer: B
Rationale: Tanner stage 2 development at age 13 in females falls within the normal pubertal
timeline (thelarche typically begins between ages 8-13). Menarche generally occurs 2-2.5
years after thelarche (Tanner stage 2), making the absence of menstruation at this stage
expected. Delayed puberty in females is defined as no breast development by age 13; this
patient has clearly entered puberty. Endocrine workup, chromosome analysis, or specialist
referral is unnecessary and would generate unwarranted cost and patient/family anxiety.
Family education and continued monitoring are the appropriate management.
Q6: A 52-year-old male presents for a comprehensive adult health assessment. He
has no significant past medical history but reports a 15-year pack smoking
history, intermittent exertional chest tightness, and a father who died of MI at age
55. Which component of the comprehensive health history is most critical to elicit
at this visit?
A. A detailed review of systems focused exclusively on cardiovascular symptoms to identify
high-risk presentations.
B. A focused family history limited to first-degree relatives and a personal safety screening.
C. A comprehensive history including family history of premature coronary
disease, lifestyle factors, psychosocial stressors, and a complete review of
systems with risk stratification. **[CORRECT]**
D. A targeted occupational history limited to physical exertion requirements to determine
functional capacity.
Correct Answer: C
Rationale: The patient presents with multiple cardiovascular risk factors (smoking,
symptoms, family history of premature CAD) requiring a comprehensive adult health
assessment that integrates family history, lifestyle, psychosocial, and occupational factors for
accurate risk stratification per USPSTF and ACC/AHA guidelines. Limiting history to a single
system risks missing comorbidities, medication interactions, and behavioral contributors that
influence both diagnosis and management. Family history should extend to second-degree
relatives when premature disease is present, and psychosocial screening is essential because
stress, depression, and social determinants significantly affect cardiovascular outcomes.
