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. Why should a nurse plan an evening snack for a child receiving Novolin N insulin?

• A. To encourage the child to adhere to the diet.
• B. To provide energy for immediate use.
• C. To help the child gain weight with extra calories.
• D. To counteract late insulin activity with nourishment.

Correct answer: D

Rationale: The correct answer is D. Novolin N insulin peaks in the evening, which can lead to hypoglycemia during the night. Providing an evening snack helps to counteract the late insulin activity and prevent hypoglycemia. Choice A is incorrect because the primary reason for the evening snack is not to encourage adherence to the diet. Choice B is incorrect as the snack is not primarily for immediate energy use. Choice C is incorrect as the goal of the snack is not to help the child gain weight but to manage blood sugar levels.

3. A nurse is evaluating a 3-year-old child’s developmental progress. The inability to perform which task indicates to the nurse that there is a developmental delay?

• A. Copying a square
• B. Hopping on one foot
• C. Catching a ball reliably
• D. Using a spoon effectively

Correct answer: A

Rationale: The correct answer is A: Copying a square. At 3 years old, children should be able to copy a square as part of their fine motor skill development. The inability to perform this task may indicate a developmental delay in fine motor skills. Choice B, hopping on one foot, typically develops around 4-5 years of age, so it is not a reliable indicator of a delay at 3. Choice C, catching a ball reliably, involves coordination skills that develop later in childhood, making it less relevant for a 3-year-old assessment. Choice D, using a spoon effectively, is more related to self-care and feeding skills rather than fine motor development, so it is not the best indicator of a developmental delay in this context.

4. An infant with a congenital heart defect is being given gavage feedings. The parents ask the nurse why this is necessary. How should the nurse respond?

• A. It limits the chance of vomiting.
• B. It allows the feeding to be administered rapidly.
• C. The energy that would have been expended on sucking is conserved.
• D. The quantity of nutritional liquid can be regulated better than with a bottle.

Correct answer: C

Rationale: Gavage feedings are necessary for infants with congenital heart defects to conserve the infant's energy by eliminating the need for sucking. This is important because sucking requires energy expenditure, which can be taxing for infants with cardiac defects. Choice A is incorrect as gavage feedings do not primarily limit the chance of vomiting. Choice B is incorrect because the speed of feeding administration is not the primary reason for using gavage feedings in this case. Choice D is incorrect as the regulation of the quantity of nutritional liquid is not the main purpose of gavage feedings in infants with congenital heart defects.

5. An infant is diagnosed with Hirschsprung disease. What nursing intervention is essential before surgery?

• A. Administering antibiotics
• B. Ensuring bowel rest
• C. Performing regular enemas
• D. Maintaining NPO status

Correct answer: D

Rationale: The correct nursing intervention essential before surgery for an infant with Hirschsprung disease is maintaining NPO (nothing by mouth) status. This is important to prevent aspiration during and after the surgical procedure. Administering antibiotics (Choice A) may be necessary in some cases but is not the priority intervention before surgery. Ensuring bowel rest (Choice B) is not directly related to preparing for surgery and may not be the most critical intervention. Performing regular enemas (Choice C) is not recommended before surgery for Hirschsprung disease as it can aggravate the condition.
