Section A: Case Overview & Patient Demographics
Q1: Olive Chaney is a 2-year-old female presenting to the clinic with her mother. What is
her most likely weight and height for a well-nourished toddler of this age?
A. 18 lb (8.2 kg), 30 in (76 cm)
B. 22 lb (10 kg), 32 in (81 cm)
C. 28 lb (12.7 kg), 2'10" (86 cm) [CORRECT]
D. 35 lb (15.9 kg), 3'2" (97 cm)
Correct Answer: C
Rationale: Olive's documented weight is 28.0 lb (12.7 kg) and height is 2'10" (86 cm),
which are appropriate for a 2-year-old female at approximately the 50th percentile.
Options A and B are below expected parameters, and option D exceeds typical
2-year-old growth.
Q2: What is the primary reason for Olive Chaney's visit to the clinic today?
A. Evaluation of a persistent cough
B. Evaluation of a new rash [CORRECT]
C. Routine 2-year well-child check
D. Follow-up for an ear infection
Correct Answer: B
Rationale: The chief complaint is evaluation of a new rash that began on the day of
presentation. While Olive has a cough, it is not the primary reason for the visit. Options
C and D are not documented as the reason for this encounter.
Q3: Olive's mother reports that the rash started on the abdomen and has since spread.
Which pattern of rash spread is most characteristic of this description?
A. Centripetal (from extremities toward the trunk)
,B. Centrifugal (from the trunk toward the extremities) [CORRECT]
C. Acral (limited to hands and feet)
D. Dermatomal (following a nerve distribution)
Correct Answer: B
Rationale: The rash spreading from the abdomen (trunk) to the arms and legs
represents a centrifugal pattern. Centripetal spread (option A) moves inward, acral
(option C) is limited to distal extremities, and dermatomal (option D) follows sensory
nerve distributions.
Q4: Which factor in Olive's history is most critical for narrowing the differential
diagnosis of her rash?
A. Family history of eczema
B. Up-to-date immunization status [CORRECT]
C. Recent travel to a tropical country
D. History of food allergies
Correct Answer: B
Rationale: Olive's up-to-date immunizations significantly reduce the likelihood of
vaccine-preventable diseases such as measles and rubella, thereby narrowing the
differential diagnosis. While other factors may be relevant, vaccination status is the
most critical differentiator in this case.
Q5: At 2 years of age, Olive falls within the typical age range for which common
exanthematous viral illness?
A. Varicella zoster virus (chickenpox)
B. Exanthema subitum (roseola) [CORRECT]
C. Infectious mononucleosis
D. Mumps
Correct Answer: B
Rationale: Roseola (exanthema subitum) caused by HHV-6 is most common in children
6 months to 2 years of age. Varicella (option A) can occur at any age but is less
age-specific, mononucleosis (option C) typically affects adolescents, and mumps
(option D) is less common due to vaccination.
, Q6: The mother reports that Olive had a high fever of 103°F that started 3 days ago and
has since resolved. What is the clinical significance of the fever resolving before the
rash appeared?
A. It suggests a bacterial superinfection
B. It is the hallmark temporal pattern of roseola [CORRECT]
C. It indicates the rash is unrelated to the fever
D. It suggests an allergic reaction to antipyretics
Correct Answer: B
Rationale: The classic presentation of roseola is 3–5 days of high fever followed by
rapid defervescence and subsequent appearance of a maculopapular rash. This
temporal pattern is pathognomonic and distinguishes roseola from many other
exanthems.
Section B: History of Presenting Illness & Symptom Analysis
Q7: When obtaining the history of present illness, which opening question is most
appropriate to begin the encounter?
A. "What antibiotics has she taken?"
B. "How can I help her today?" [CORRECT]
C. "Does she have a history of asthma?"
D. "When was her last vaccination?"
Correct Answer: B
Rationale: "How can I help her today?" is a patient-centered, open-ended question that
allows the mother to express her primary concern. Options A, C, and D are closed-ended
or premature without first establishing the chief complaint.
Q8: The mother reports that Olive's rash started this morning and has spread
significantly. Which follow-up question is most important to characterize the rash?
A. "Has she had any surgeries?"
B. "On what part of her body did the rash start and where did it spread?" [CORRECT]
C. "What is her favorite food?"
D. "Does she have any pets at home?"
Correct Answer: B
