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.

A parent tearfully tells a nurse, 'They think our child is developmentally delayed. We are thinking about investigating a preschool program for cognitively impaired children.' What is the nurse's most appropriate response?
- A. Praise the parent for the decision and encourage the plan.
- B. Ask for more specific information related to the developmental delays.
- C. Advise the parent to have the healthcare provider help choose an appropriate program.
- D. Explain that this may be a premature action and the developmental delays could disappear.
Correct Answer: B
Rationale: The most appropriate response in this situation is to ask for more specific information related to the developmental delays. By seeking additional details, the nurse can better understand the child's needs and provide tailored guidance and support to the parent. Praising the parent (Choice A) before fully grasping the situation may not be beneficial. Advising the parent to involve the healthcare provider in selecting a program (Choice C) is premature without a comprehensive understanding of the child's developmental delays. Explaining that the delays might resolve on their own (Choice D) is inappropriate as it dismisses the parent's concerns and the necessity for timely and appropriate interventions.
A child is being assessed for suspected intussusception. What clinical manifestation is the nurse likely to observe?
- A. Projectile vomiting
- B. Currant jelly stools
- C. Abdominal distension
- D. Constipation
Correct Answer: C
Rationale: The correct clinical manifestation that a nurse is likely to observe in a child with suspected intussusception is abdominal distension. Intussusception is a medical emergency where a part of the intestine folds into itself, causing obstruction. Abdominal distension is a common symptom due to the obstruction and the build-up of gases and fluids. While currant jelly stools (Choice B) are a classic sign of intussusception, they are typically seen in later stages of the condition and may not be present during the initial assessment. Projectile vomiting (Choice A) is more commonly associated with conditions like pyloric stenosis. Constipation (Choice D) is not a typical manifestation of intussusception; the condition usually presents with severe colicky abdominal pain and possible passage of blood and mucus in stools.
Seizures in children most often result from
- A. an abrupt rise in body temperature
- B. an inflammatory process in the brain
- C. a temperature greater than 102°F
- D. a life-threatening infection
Correct Answer: A
Rationale: Seizures in children most often result from an abrupt rise in body temperature, leading to febrile seizures. Febrile seizures are common in young children and are typically triggered by a rapid increase in body temperature, often due to infections or other causes. An inflammatory process in the brain (Choice B) is less common as a cause of seizures in children and is usually associated with specific conditions like encephalitis or meningitis. While a temperature greater than 102°F (Choice C) may trigger a febrile seizure, it is the abrupt rise in temperature that is the primary cause. Choice D, a life-threatening infection, is a broad and less specific cause compared to the direct trigger of an abrupt rise in body temperature.
Why does a cleft lip predispose an infant to infection, concerning a nurse caring for the infant?
- A. Waste products accumulate along the defect.
- B. There is inadequate circulation in the defective area.
- C. Nutrition is inadequate due to ineffective feeding.
- D. Mouth breathing dries the oropharyngeal mucous membranes.
Correct Answer: D
Rationale: Mouth breathing due to a cleft lip can dry the mucous membranes, increasing their susceptibility to infection. While waste product accumulation (Choice A) and inadequate circulation (Choice B) may contribute to complications, they are not directly related to infection in this context. Inadequate nutrition (Choice C) may affect overall health but is not the primary reason for infection predisposition in this case.
A home care nurse is visiting a family for the first time. The 4-week-old infant had surgery for exstrophy of the bladder and creation of an ileal conduit soon after birth. When the nurse arrives, the mother appears tired, and the baby is crying. After an introduction, which is the most appropriate statement by the nurse?
- A. "Tell me about your daily routine."
- B. "You look tired. Is everything all right?"
- C. "When was the last time the baby had a bottle?"
- D. "Oh, it looks like you two are having a bad day."
Correct Answer: A
Rationale: The most appropriate statement by the nurse in this scenario is to inquire about the family's daily routine. This question allows the nurse to gather information about the family dynamics, the care routine for the infant post-surgery, feeding schedules, and potential stressors. It opens the conversation in a non-intrusive manner and helps the nurse assess the family's situation to provide appropriate support. Choices B, C, and D do not address the situation effectively. Asking about the daily routine is crucial for the nurse to understand the family's needs and offer targeted assistance.
