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. An infant is admitted to the neonatal intensive care unit (NICU) with exstrophy of the bladder. What covering should the nurse use to protect the exposed area?

• A. Loose diaper
• B. Dry gauze dressing
• C. Moist sterile dressing
• D. Petroleum jelly gauze pad

Correct answer: C

Rationale: In cases of exstrophy of the bladder, a moist sterile dressing is the most appropriate choice to protect the exposed bladder tissue. Moist sterile dressings help maintain a clean environment, prevent infection, and promote healing. A loose diaper (Choice A) may not provide adequate protection and may lead to contamination. Dry gauze dressing (Choice B) could adhere to the wound and cause trauma upon removal. Petroleum jelly gauze pad (Choice D) is not ideal as it may not provide the necessary barrier against infection and could potentially cause irritation.

3. Why does a cleft lip predispose an infant to infection?

• A. Waste products accumulate along the defect.
• B. There is evidence of 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: The correct answer is D. Mouth breathing due to a cleft lip can dry the mucous membranes, making them more susceptible to infection. Choice A is incorrect because waste products do not accumulate along the defect to predispose the infant to infection. Choice B is incorrect as there is no evidence of inadequate circulation being a primary factor in infection predisposition in cleft lip cases. Choice C is incorrect because although ineffective feeding may lead to other issues, it is not the main reason for infection predisposition in infants with a cleft lip.

4. When evaluating a child with a diagnosis of attention-deficit/hyperactivity disorder (ADHD) for medication management, what is an important assessment for the nurse to perform?

• A. Assess the child's sleep patterns
• B. Assess the child's dietary intake
• C. Assess the child's academic performance
• D. Assess the child's behavior at home

Correct answer: B

Rationale: Assessing the child's dietary intake is crucial as certain foods and additives can affect ADHD symptoms. Ensuring a balanced diet can help manage symptoms and provide proper nutrition. Assessing sleep patterns (Choice A) is also important, but dietary intake is more directly linked to symptom management in ADHD. Academic performance (Choice C) and behavior at home (Choice D) may be affected by ADHD but are not as directly related to medication management as dietary intake.

5. A child with a diagnosis of appendicitis is scheduled for surgery. What preoperative intervention is important for the nurse to perform?

• A. Administering antibiotics
• B. Maintaining strict NPO status
• C. Encouraging fluid intake
• D. Monitoring for signs of infection

Correct answer: B

Rationale: The correct preoperative intervention for a child with appendicitis scheduled for surgery is maintaining strict NPO (nothing by mouth) status. This is crucial to reduce the risk of aspiration during anesthesia induction and prevent potential complications during surgery. Administering antibiotics may be a part of the treatment plan but is not a preoperative intervention. Encouraging fluid intake is contraindicated preoperatively to avoid delays in surgery and complications related to anesthesia. Monitoring for signs of infection is important postoperatively to assess for any complications that may arise due to the surgical procedure.
