Which vaccine is contraindicated in a child with a history of severe egg allergy?
- A. MMR
- B. Varicella
- C. Influenza
- D. Hepatitis B
Correct Answer: C
Rationale: The correct answer is C: Influenza. The influenza vaccine is produced using egg-based technology, so individuals with a severe egg allergy are at risk of an allergic reaction if vaccinated with the influenza vaccine. This is due to the potential presence of egg proteins in the vaccine. Choices A, B, and D are not contraindicated in children with severe egg allergy. The MMR and Varicella vaccines do not pose a risk for children with egg allergies, and the Hepatitis B vaccine is also safe for these individuals.

For a child with Kawasaki disease, which symptom is most indicative of the acute phase?
- A. Strawberry tongue
- B. Joint pain
- C. Rash
- D. Peeling skin
Correct Answer: A
Rationale: The correct answer is A: Strawberry tongue. In Kawasaki disease, a 'strawberry tongue' is most indicative of the acute phase. This refers to the tongue appearing red and swollen with enlarged fungiform papillae, giving it a strawberry-like appearance. Joint pain (Choice B) is more commonly associated with other conditions like rheumatoid arthritis. Rash (Choice C) and peeling skin (Choice D) are also seen in Kawasaki disease but are not as specific to the acute phase as the presence of a strawberry tongue.
What disease should be suspected in a 3-day-old infant presenting with abdominal distention, vomiting, and failure to pass meconium?
- A. Pyloric stenosis
- B. Intussusception
- C. Hirschsprung disease
- D. Celiac disease
Correct Answer: C
Rationale: Hirschsprung disease should be suspected in a newborn with abdominal distention, vomiting, and failure to pass meconium. This condition arises from a congenital absence of nerve cells in a portion of the colon, leading to severe constipation and intestinal obstruction. Pyloric stenosis typically presents with non-bilious projectile vomiting in the first few weeks of life. Intussusception classically manifests with sudden onset of colicky abdominal pain and currant jelly stools. Celiac disease may present with chronic diarrhea, failure to thrive, and abdominal distention but is less likely in this scenario.
Which of the following is a characteristic finding in Kawasaki disease?
- A. Strawberry tongue
- B. Polyarthritis
- C. Hematuria
- D. Rashes
Correct Answer: A
Rationale: A 'strawberry tongue' is a characteristic finding in Kawasaki disease. The presence of a 'strawberry tongue' is a classic sign of Kawasaki disease, along with other features such as conjunctivitis and rash. Choice B, polyarthritis, is not typically seen in Kawasaki disease. Choice C, hematuria, is not a common finding in Kawasaki disease but may be seen in other conditions. Choice D, rashes, are present in Kawasaki disease but are not as specific or characteristic as the 'strawberry tongue'. Therefore, the correct answer is A.
The nurse is preparing to admit a 6-year-old child with celiac disease. What clinical manifestations should the nurse expect to observe?
- A. Steatorrhea
- B. All are correct
- C. Malnutrition
- D. Foul-smelling stools
Correct Answer: B
Rationale: Celiac disease often presents with steatorrhea, malnutrition, and foul-smelling stools due to the malabsorption of nutrients. Therefore, all the manifestations listed (steatorrhea, malnutrition, foul-smelling stools) are expected in a child with celiac disease. Polycythemia is not associated with celiac disease, making choice B the correct answer.
What is a key distinguishing feature of bronchiolitis in infants?
- A. Dry cough
- B. Wheezing
- C. Stridor
- D. Productive cough
Correct Answer: B
Rationale: The correct answer is B: Wheezing. Wheezing is a key distinguishing feature of bronchiolitis in infants, typically caused by respiratory syncytial virus (RSV) infection. Bronchiolitis is characterized by inflammation and mucus buildup in the small airways of the lungs, leading to wheezing sounds during breathing. Choices A, C, and D are incorrect because dry cough, stridor, and productive cough are not typical features of bronchiolitis in infants.
