1. How is the diagnosis of Hirschsprung disease confirmed in a 1-month-old infant admitted to the pediatric unit?
- A. Colonoscopy
- B. Rectal biopsy
- C. Multiple saline enemas
- D. Fiberoptic nasoenteric tube
Correct answer: B
Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. It confirms the absence of ganglion cells in the affected bowel segment, which is characteristic of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for confirmation as it may not provide a definitive result. Multiple saline enemas (Choice C) are utilized in the treatment of meconium ileus, a complication of cystic fibrosis, and not in the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a diagnostic tool for Hirschsprung disease; it is commonly used for gastrointestinal decompression or feeding purposes but does not confirm the diagnosis.
2. A 4-year-old child is admitted to the hospital with a diagnosis of epiglottitis. What is the priority nursing intervention?
- A. Administer antibiotics
- B. Provide humidified oxygen
- C. Keep the child NPO
- D. Position the child upright
Correct answer: C
Rationale: The priority nursing intervention for a 4-year-old child admitted with epiglottitis is to keep the child NPO (nothing by mouth). This is crucial to prevent further airway compromise due to the inflamed epiglottis. Administering antibiotics may be necessary but is not the priority at this moment. Providing humidified oxygen can support oxygenation but does not address the immediate risk of airway obstruction. Positioning the child upright may help with breathing but does not address the risk of aspiration. Keeping the child NPO is essential to maintain a patent airway and prevent complications associated with epiglottitis.
3. A newborn is admitted to the neonatal intensive care unit (NICU) with choanal atresia. Which part of the infant’s body should the nurse assess?
- A. Rectum
- B. Nasopharynx
- C. Intestinal tract
- D. Laryngopharynx
Correct answer: B
Rationale: Choanal atresia is a congenital condition characterized by the blockage of the nasal passages, specifically the choanae that connect the nasal cavity to the nasopharynx. The nurse should assess the nasopharynx to identify any obstruction, confirm the diagnosis, and assess the severity of the condition. Choices A, C, and D are incorrect as they do not pertain to choanal atresia. Choanal atresia specifically involves the nasal passages and nasopharynx, not the rectum, intestinal tract, or laryngopharynx.
4. A school nurse is educating parents of school-age children on the significance of immunizations for childhood communicable diseases. What preventable disease may lead to the complication of encephalitis?
- A. Varicella (Chickenpox)
- B. Scarlet fever
- C. Poliomyelitis
- D. Whooping cough
Correct answer: A
Rationale: The correct answer is A: Varicella (Chickenpox). Varicella can lead to the complication of encephalitis, characterized by brain inflammation. Encephalitis is a known complication of chickenpox in rare cases. Scarlet fever (choice B) is caused by Streptococcus bacteria and does not typically result in encephalitis. Poliomyelitis (choice C) primarily affects the spinal cord and does not lead to encephalitis. Whooping cough (choice D) can cause severe coughing spells but does not directly result in encephalitis.
5. The nurse is assessing a 3-year-old boy whose parents brought him to the clinic when they noticed that the right side of his abdomen was swollen. What finding would suggest this child has a neuroblastoma?
- A. The child has a maculopapular rash on his palms.
- B. The parents report that their son is vomiting and not eating well.
- C. The parents report that their son is irritable and not gaining weight.
- D. Auscultation reveals wheezing with diminished lung sounds.
Correct answer: B
Rationale: Vomiting and poor appetite are common symptoms of neuroblastoma, a malignancy that arises from neural crest cells in the adrenal glands or sympathetic nervous system. This tumor can cause abdominal swelling due to its location and size, leading to symptoms like vomiting and decreased appetite. The presence of a maculopapular rash on the palms (Choice A) is not a typical finding associated with neuroblastoma. Irritability and failure to thrive (Choice C) are nonspecific symptoms that can be seen in various conditions but are not specifically indicative of neuroblastoma. Auscultation revealing wheezing with diminished lung sounds (Choice D) may suggest respiratory conditions rather than neuroblastoma.
