Nursing Elites

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. The school nurse is caring for a boy with hemophilia who fell on his arm during recess. What supportive measures should the nurse use until factor replacement therapy can be instituted?

• A. Apply warm, moist compresses
• B. Apply pressure for at least 1 minute
• C. Elevate the area above the level of the heart
• D. Begin passive range-of-motion unless the pain is severe

Correct answer: C

Rationale: Elevating the affected area above the level of the heart is the correct supportive measure for a child with hemophilia who has experienced trauma. This action helps reduce bleeding and swelling by promoting venous return and preventing further pooling of blood in the affected area. Applying warm, moist compresses (Choice A) may not be recommended as it can potentially increase bleeding by dilating blood vessels. Applying pressure for at least 1 minute (Choice B) can be helpful for minor cuts or wounds but may not be as effective in managing bleeding in a child with hemophilia. Beginning passive range-of-motion (Choice D) should be avoided as it can exacerbate bleeding and cause further damage in a child with hemophilia.

3. What behavior does the nurse anticipate when feeding a newborn with choanal atresia?

• A. Chokes during feeding
• B. Experiences swallowing challenges
• C. Lacks hunger cues
• D. Takes about half of the feeding

Correct answer: D

Rationale: When feeding a newborn with choanal atresia, the nurse can anticipate that the infant may take only part of the feeding before pausing for air. This is due to the fact that infants with choanal atresia struggle to breathe through their nose while feeding. Choice A is incorrect as choking typically involves a more severe airway obstruction. Choice B is incorrect because difficulty swallowing is not the primary concern in choanal atresia. Choice C is incorrect as the issue is not related to hunger cues but rather the physiological challenges associated with breathing while feeding.

4. A nurse is assessing a 3-month-old infant with suspected pyloric stenosis. What clinical manifestation is the nurse likely to observe?

• A. Projectile vomiting
• B. Diarrhea
• C. Constipation
• D. Abdominal distension

Correct answer: A

Rationale: Projectile vomiting is the hallmark clinical manifestation of pyloric stenosis in infants. In pyloric stenosis, the muscle surrounding the opening between the stomach and the small intestine thickens, leading to obstruction. This obstruction causes forceful, projectile vomiting, which is typically non-bilious (does not contain bile) and occurs after feedings. Choices B, C, and D are incorrect because diarrhea, constipation, and abdominal distension are not typical symptoms of pyloric stenosis.

5. A nurse is developing a teaching plan for an 8-year-old child who has recently been diagnosed with type 1 diabetes. What developmental characteristic of a child this age should the nurse consider?

• A. Child is in the concrete operational stage of cognition.
• B. Child’s dependence on peer influence is increasing.
• C. Child will welcome opportunities for participation in self-care.
• D. Child’s developmental stage involves achieving a sense of autonomy.

Correct answer: C

Rationale: The correct answer is C. At the age of 8, children are typically in the stage of industry vs. inferiority according to Erikson's psychosocial theory. This stage is characterized by a desire to engage in productive activities and take on responsibilities. Thus, the child will likely welcome opportunities for participation in self-care related to their diabetes management. Choices A, B, and D are incorrect. Choice A is inaccurate as children at this age are usually in the concrete operational stage of cognitive development, not abstract. Choice B is incorrect because while peer influence is significant, it has not reached its peak at this age. Choice D is wrong as achieving a sense of identity is a developmental task more commonly associated with adolescence, not 8-year-old children.
