OVERVIEW:
CMN 571 Unit 5 Test – 2026/2027 covers pediatric primary care focused on
gastrointestinal, genitourinary, and dermatologic systems. Topics include pyloric
stenosis, intussusception, biliary atresia, Hirschsprung, GERD, constipation,
encopresis, UTIs, vesicoureteral reflux, enuresis, nephrotic syndrome,
glomerulonephritis, HSP, balanitis, phimosis, cryptorchidism, atopic dermatitis,
impetigo, tinea capitis, scabies, and hemangiomas, emphasizing assessment,
differential diagnosis, management, and family education strategies for nurse
practitioners.
Answers are in bold Green, with rationales after.
1. A 6-month-old with projectile non-bilious vomiting immediately after
feeds, with olive-shaped RUQ mass and hypochloremic metabolic
alkalosis. Most likely diagnosis?
A. Pyloric stenosis
B. Duodenal atresia
C. Intussusception
D. GERD
, Rationale: Classic pyloric stenosis: hypertrophic pylorus, non-bilious
projectile vomiting, palpable olive, labs show low Cl, low K, high
HCO3. US shows pyloric muscle thickness >3mm.
2. First-line treatment for uncomplicated atopic dermatitis in a 4-year-old
involves:
A. High-potency topical steroids continuously
B. Liberal fragrance-free emollients and low-potency topical steroids
for flares
C. Systemic antihistamines alone
D. Oral corticosteroids
Rationale: Atopic dermatitis: daily emollients, trigger avoidance,
bleach baths if recurrent Staph, intermittent low-mid potency
steroids for flares. High-potency continuous use risks skin atrophy.
3. A 3-year-old with currant jelly stools, intermittent abdominal pain
pulling knees to chest, sausage-shaped RUQ mass. Next best step?
A. Abdominal X-ray only
B. Observation
C. Air-contrast enema both diagnostic and therapeutic
D. Give loperamide
Rationale: Intussusception triad: colicky pain, currant jelly stool,
palpable mass. Air enema is diagnostic and therapeutic if no
peritonitis, perforation, or shock.
4. Which finding distinguishes biliary atresia from physiologic jaundice?
A. Indirect hyperbilirubinemia resolving by day 5
, B. Jaundice with normal stools and normal LFTs
C. Jaundice beyond 2 weeks, acholic stools, direct hyperbilirubinemia
D. Brief jaundice after breastfeeding
Rationale: Biliary atresia: persistent jaundice >2 weeks, conjugated
hyperbilirubinemia, pale acholic stools, dark urine, hepatomegaly.
Requires prompt HIDA scan and Kasai portoenterostomy.
5. Kawasaki disease diagnostic criteria includes fever ≥5 days plus 4 of 5:
conjunctivitis, mucositis, extremity changes, rash, and:
A. Hepatosplenomegaly
B. Diarrhea
C. Cervical lymphadenopathy >1.5 cm
D. Arthralgia
Rationale: Kawasaki: 5-day fever + 4/5 criteria: bilateral non-
exudative conjunctivitis, strawberry tongue/cracked lips,
polymorphous rash, edema/desquamation hands/feet, cervical LAD
≥1.5cm. Risk coronary aneurysms.
6. Best management for diaper dermatitis with bright red confluent
patches involving folds and satellite lesions?
A. Topical nystatin for candidal infection
B. Zinc oxide only
C. Topical high-potency steroid
D. Oral acyclovir
Rationale: Satellite lesions and intertriginous fold involvement
indicates candidal diaper dermatitis. Treat with topical antifungal like
nystatin or clotrimazole plus barrier care.
