MSN 629 Week 3 Quiz – Pediatric Primary Care and
Pharmacology
Key Exam Coverage Areas
1. Pediatric skin lesions and recognition of systemic disease clues
2. Common bacterial, viral, fungal, and parasitic skin infections
3. Atopic dermatitis and inflammatory pediatric skin disorders
4. Allergic conditions and hypersensitivity reactions
5. Pediatric infectious diseases and appropriate treatment
6. Pharmacologic management of common pediatric conditions
7. Pediatric medication dosing, safety, and adverse effects
8. Differential diagnosis using pediatric history and physical findings
9. Age-appropriate assessment and clinical decision-making
10. Patient and caregiver education, prevention, and follow-up
Questions
1. Which finding in a child with a skin disorder should most strongly prompt evaluation for an
underlying systemic condition?
A. A single uncomplicated abrasion
B. A transient insect bite
C. Multiple unusual skin findings associated with other systemic symptoms
D. Mild dryness during winter
Answer: C
Rationale: Multiple unusual cutaneous findings combined with systemic symptoms may indicate an
underlying disease requiring additional evaluation. An abrasion, insect bite, or uncomplicated dryness
generally does not by itself suggest systemic disease.
2. What clinical feature most commonly distinguishes atopic dermatitis from many uncomplicated
infectious skin conditions in young children?
A. Chronic pruritus with recurrent eczematous inflammation
B. Sudden development of a solitary pustule
C. A sharply localized traumatic wound
D. Immediate formation of a fluctuant abscess
Answer: A
1
,Rationale: Atopic dermatitis typically causes chronic or recurrent pruritic, inflamed, eczematous skin.
Pustules, traumatic wounds, and abscesses point toward other diagnoses.
3. Which symptom pattern in a child would be most consistent with allergic rhinitis rather than an
acute bacterial infection?
A. Persistent unilateral facial swelling with severe pain
B. Recurrent sneezing, nasal itching, and clear rhinorrhea
C. High fever with toxic appearance
D. Purulent drainage accompanied by severe systemic illness
Answer: B
Rationale: Allergic rhinitis commonly produces sneezing, nasal itching, and clear rhinorrhea. Fever, toxic
appearance, and significant facial pain suggest infectious or other pathology.
4. Why should pediatric medication doses generally be calculated according to the child's weight
when appropriate?
A. Weight eliminates the need to assess renal function
B. Weight-based dosing helps account for differences in medication requirements between children
C. Weight-based dosing prevents every possible adverse drug reaction
D. Weight automatically determines the duration of therapy
Answer: B
Rationale: Children vary considerably in medication requirements, and weight-based dosing helps provide
an appropriate dose. It does not eliminate the need to consider organ function, adverse effects, or
treatment duration.
5. Which lesion description would most strongly support impetigo in a young child?
A. Thickened plaques limited to pressure points
B. Honey-colored crusted lesions on superficial affected skin
C. Deep purple nodules without surface changes
D. Symmetric bruising without inflammation
Answer: B
Rationale: Impetigo commonly produces superficial lesions that develop characteristic honey-colored
crusting. The other descriptions are not typical of uncomplicated impetigo.

, 6. What is the most appropriate reason for carefully reviewing a child's medication history during a
dermatologic evaluation?
A. Medications can cause or worsen certain skin manifestations
B. Medications never influence dermatologic findings
C. Medication history determines the child's vaccination schedule
D. Medication history replaces the physical examination
Answer: A
Rationale: Drug reactions can produce rashes, urticaria, photosensitivity, and other skin findings.
Medication history is therefore an important component of pediatric assessment.
7. Which presentation would be most concerning for a serious allergic reaction requiring immediate
intervention?
A. Mild localized itching after outdoor activity
B. Chronic dry skin without respiratory symptoms
C. Urticaria accompanied by wheezing and difficulty breathing
D. Small isolated area of uncomplicated dermatitis
Answer: C
Rationale: Urticaria combined with respiratory compromise may indicate anaphylaxis and requires
immediate treatment. Mild localized skin symptoms without systemic involvement are less immediately
dangerous.
8. How should a primary care provider approach a child whose rash is accompanied by fever and
significant lethargy?
A. Assume the rash is allergic and provide routine skin care
B. Delay assessment until the rash has been present for one week
C. Perform prompt evaluation for potentially significant infection or systemic illness
D. Recommend only an over-the-counter moisturizer
Answer: C
Rationale: Fever and lethargy accompanying a rash can indicate systemic infection or another serious
condition. Prompt clinical assessment is appropriate.
9. Which characteristic is particularly useful when differentiating pediatric skin disorders during the
physical examination?
