,Question
A NP constructs a three-generation pedigree during a well-child visit. Which statement BEST
reflects the purpose of this assessment?
Options
A. It identifies current behavioral concerns requiring referral for psychological intervention
B. It assists in identifying inherited risks and guiding anticipatory guidance
C. It evaluates environmental exposures contributing to acquired pediatric conditions
D. It replaces the need for genetic testing when family history is well documented
Correct Answer
B. It assists in identifying inherited risks and guiding anticipatory guidance (or supervision)
Rationale
Three-Generation Pedigree (Genogram / Family History): Constructing a pedigree that spans
three generations (child/siblings, parents, grandparents/aunts/uncles) is a standard tool used in
primary pediatric care to map out genetic and familial disease patterns. Its primary purpose is to
identify heritable risks (e.g., cardiovascular disease, asthma, diabetes, hereditary cancers) early
on, allowing the provider to offer tailored anticipatory guidance, preventive counseling, and age-
appropriate screening.
Why others are incorrect:
o A: Pedigrees focus on genetic/familial patterns rather than acute, current behavioral
concerns requiring psychological therapy.
o C: Environmental exposures are evaluated through environmental history taking (e.g., lead
risk screenings, housing assessment), not a genetic family tree.
o D: A family pedigree helps determine if genetic testing is warranted; it never replaces
confirmatory genetic diagnostic testing when clinically indicated.
,Question
A 15-year-old has an incipient ingrown toenail with mild erythema but no purulence. Which intervention
BEST reflects evidence-based conservative management?
Options
A. Placing cotton under the nail edge and daily repacking
B. Complete nail removal
C. Prophylactic oral antibiotics
D. Partial nail removal
Correct AnswerA. Placing cotton under the nail edge and daily repacking
Rationale
Stage 1 / Incipient Ingrown Toenail (Mild erythema, minimal edema, no purulence):
Mild/incipient stages should first be treated with conservative non-surgical measures. The
cotton-wick technique (placing cotton under the lateral nail fold/edge and replacing/repacking it
daily) gently elevates the nail edge away from the surrounding soft tissue fold, allowing the nail to
grow outward clear of the skin.
Why others are incorrect:
o B & D (Complete / Partial nail removal): Surgical options (partial or complete nail
removal/avulsion) are reserved for moderate-to-severe, recurrent, or purulent (Stage 2/3)
ingrown toenails that fail conservative therapy.
o C (Prophylactic oral antibiotics): Oral antibiotics are not indicated for an uncomplicated
incipient ingrown toenail without active bacterial infection or purulence.
, Question
A 9-year-old develops linear streaks of intensely pruritic erythema and vesicles on the forearm 48 hours
after hiking in the woods. The rash is sharply demarcated and weeping in some areas. Which of the
following BEST explains the pathophysiology of this condition?
Options
A. Direct bacterial infection of the epidermis
B. Immediate IgE-mediated hypersensitivity reaction
C. Type IV delayed hypersensitivity reaction
D. Immune complex deposition in dermal vessels
Correct Answer
C. Type IV delayed hypersensitivity reaction
Rationale
Clinical Presentation: The clinical scenario describes classic allergic contact dermatitis caused
by plant exposure (most commonly urushiol from poison ivy, oak, or sumac). The presentation
features linear streak patterns from plant contact, intense itching, edema, vesicles, and onset
24–48 hours post-exposure.
Pathophysiology: Allergic contact dermatitis is a Type IV (cell-mediated, delayed)
hypersensitivity reaction. Sensitized T-lymphocytes respond upon re-exposure to the antigen
(urushiol), triggering an inflammatory response that takes 24 to 72 hours to peak.
Why others are incorrect:
o A (Direct bacterial infection): The rash is non-infectious; it is an immune-mediated
allergic reaction to plant oleoresin.
o B (Immediate IgE-mediated / Type I): Type I reactions involve IgE antibodies and mast
cell degranulation occurring within minutes to hours (e.g., urticaria, anaphylaxis), not 48
hours later.
o D (Immune complex deposition / Type III): Type III reactions involve antibody-antigen
immune complexes depositing in blood vessels (e.g., serum sickness, vasculitis).
