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. After an infant has had corrective surgery for hypertrophic pyloric stenosis (HPS), what should the nurse teach a parent to do immediately after a feeding to limit vomiting?

• A. Rock the infant.
• B. Place the infant in an infant seat.
• C. Place the infant flat on the right side.
• D. Keep the infant awake with sensory stimulation.

Correct answer: B

Rationale: Correct Answer: B. Placing the infant in an infant seat is essential after feeding to help keep the head elevated and reduce the risk of vomiting. This position helps prevent regurgitation of formula or milk. Rocking the infant (Choice A) is incorrect because it may exacerbate vomiting due to the movement. Placing the infant flat on the right side (Choice C) is incorrect as it does not promote proper digestion and can increase the risk of vomiting. Keeping the infant awake with sensory stimulation (Choice D) is incorrect as it does not directly address the physiological need to reduce vomiting after feeding.

3. 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.

4. What finding would lead the nurse to suspect that a child has Turner syndrome?

• A. Webbed neck
• B. Microcephaly
• C. Gynecomastia
• D. Cognitive delay

Correct answer: A

Rationale: A webbed neck is a key feature seen in Turner syndrome, a genetic condition that occurs in females due to a complete or partial absence of one of the X chromosomes. This physical trait is caused by excess skin on the neck, giving it a webbed appearance. Microcephaly (Choice B) is a condition characterized by a smaller than average head size and is not typically associated with Turner syndrome. Gynecomastia (Choice C) refers to breast enlargement in males and is not a common finding in Turner syndrome, which affects females. Cognitive delay (Choice D) is not a specific characteristic of Turner syndrome, as the syndrome primarily affects physical development and may not necessarily impact cognitive abilities.

5. What behavior is essential for preventing in a child postoperatively after undergoing heart surgery to repair defects associated with tetralogy of Fallot?

• A. Crying
• B. Coughing
• C. Straining at stool
• D. Unnecessary movement

Correct answer: C

Rationale: Preventing straining at stool is crucial postoperatively after heart surgery for tetralogy of Fallot to avoid increasing intrathoracic pressure and placing stress on the surgical site. This can help prevent complications and promote faster healing. While crying, coughing, and unnecessary movement are common postoperative behaviors, they are not specifically linked to worsening outcomes in this context. Straining at stool is particularly emphasized due to its potential to impact the surgical site and overall recovery process.
