,NUR 636 Module 7 Pediatric Primary Care 2026/2027 Questions And
Answers SNHU
Q1. A 3-year-old has persistent fever, bilateral nonpurulent
conjunctival injection, cracked red lips, a polymorphous rash, and
swollen hands. Which diagnosis should be strongly considered?
A) Scarlet fever
B) Kawasaki disease
C) Juvenile idiopathic arthritis
D) Atopic dermatitis
Correct Answer: B) Kawasaki disease
Rationale: Kawasaki disease is an acute systemic vasculitis characterized
by persistent fever with features such as bilateral conjunctival injection, oral
mucosal changes, rash, extremity changes, and cervical lymphadenopathy.
Early recognition is important because treatment reduces coronary
complications.
Q2. What is the most clinically important cardiovascular
complication of Kawasaki disease?
A) Isolated sinus tachycardia
B) Transient hypertension
C) Mild respiratory sinus arrhythmia
D) Coronary artery aneurysm
Correct Answer: D) Coronary artery aneurysm
Rationale: Coronary artery involvement is the major long-term concern in
Kawasaki disease. Untreated inflammation can produce dilation or aneurysm
formation, creating later risks of thrombosis, stenosis, myocardial ischemia,
and other cardiac complications.
Q3. Which test is particularly important after Kawasaki disease is
suspected or diagnosed?
A) Echocardiography
B) Pulmonary function testing
C) Electroencephalography
, D) Renal ultrasonography
Correct Answer: A) Echocardiography
Rationale: Echocardiography evaluates coronary dimensions and other
cardiac effects of Kawasaki disease. A normal initial study does not negate a
clinically compatible diagnosis, and follow-up imaging is determined by the
child's coronary findings and clinical course.
Q4. Which treatment is central to initial management of acute
Kawasaki disease?
A) Oral penicillin alone
B) Antihistamine therapy
C) Intravenous immunoglobulin with aspirin as clinically directed
D) Topical corticosteroids
Correct Answer: C) Intravenous immunoglobulin with aspirin as clinically
directed
Rationale: Timely intravenous immunoglobulin is the central treatment for
acute Kawasaki disease and substantially reduces coronary artery
complications. Aspirin is also incorporated into current treatment strategies,
with dosing and subsequent antiplatelet management based on the clinical
phase and coronary status.
Q5. A child has prolonged unexplained fever and only three classic
Kawasaki features. What is the most appropriate reasoning
approach?
A) Exclude Kawasaki disease because all classic features are required
B) Consider incomplete Kawasaki disease and use supporting laboratory and
echocardiographic findings
C) Diagnose viral illness without additional evaluation
D) Wait until every classic feature appears
Correct Answer: B) Consider incomplete Kawasaki disease and use
supporting laboratory and echocardiographic findings
Rationale: Children can have incomplete Kawasaki disease without meeting
the full classic feature count. Persistent compatible fever should prompt
structured evaluation using clinical findings, inflammatory laboratory results,
