Which congenital heart defect causes a "boot-shaped" heart on a chest x-ray?
- A. Tetralogy of Fallot
- B. Coarctation of the aorta
- C. Transposition of the great arteries
- D. Ventricular septal defect
Correct Answer: A
Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot, a congenital heart defect with four distinct abnormalities, often presents with a "boot-shaped" heart on chest x-ray due to right ventricular hypertrophy. This characteristic finding is due to the specific combination of defects in this condition. Coarctation of the aorta (choice B), Transposition of the great arteries (choice C), and Ventricular septal defect (choice D) do not typically result in a "boot-shaped" heart on a chest x-ray like Tetralogy of Fallot does.

A health care provider prescribes feedings of 1 to 2 oz Pedialyte every 3 hours and to advance to 1/2 strength Similac with iron as tolerated postoperatively for an infant who had a pyloromyotomy. The nurse should decide to advance the feeding if which occurs?
- A. The infant's IV line has infiltrated.
- B. The infant has not voided since surgery.
- C. The infant's mother states the infant is tolerating the feeding okay.
- D. The infant is taking the Pedialyte without vomiting or distention.
Correct Answer: D
Rationale: The decision to advance feedings after a pyloromyotomy is based on the infant's ability to tolerate the current feedings without vomiting or abdominal distention. Ensuring the infant can keep down Pedialyte is the key indicator for moving to the next stage of feeding. Choices A, B, and C are incorrect because they do not directly relate to the infant's ability to tolerate the feeding. An infiltrated IV line, lack of voiding, or the mother's statement do not provide direct information on the infant's tolerance to the feeding, unlike the absence of vomiting and distention.
The nurse is caring for an infant who had surgical repair of a tracheoesophageal fistula 24 hours ago. Gastrostomy feedings have not been started. What do nursing actions related to the gastrostomy tube include?
- A. Keep the tube clamped.
- B. Suction the tube as needed.
- C. Leave the tube open to gravity drainage.
- D. Secure the tube with tape.
Correct Answer: C
Rationale: Leaving the gastrostomy tube open to gravity drainage prevents the accumulation of air and fluids, reducing the risk of complications such as vomiting or aspiration in the immediate postoperative period. Keeping the tube clamped or suctioning it can lead to pressure buildup, increasing the risk of complications. Securing the tube with tape is important but not the primary action related to the gastrostomy tube in this case.
An infant is born with a gastroschisis. Care preoperatively should include which priority intervention?
- A. Prone position
- B. Sterile water feedings
- C. Monitoring serum laboratory electrolytes
- D. Covering the defect with a sterile bowel bag
Correct Answer: D
Rationale: The correct priority intervention for an infant with gastroschisis is to cover the exposed abdominal contents with a sterile bowel bag. This action helps protect the intestines from injury, contamination, and dehydration before surgical repair. Choice A, placing the infant in the prone position, is not appropriate as it does not address the immediate need to protect the exposed intestines. Choice B, sterile water feedings, and Choice C, monitoring serum laboratory electrolytes, are not the priority interventions for this condition. Sterile water feedings may not provide the necessary protection for the exposed intestines, and monitoring electrolytes, while important, is secondary to the immediate need for protection and hydration of the exposed abdominal contents.
What disease should be suspected in a 3-day-old infant presenting with abdominal distention, vomiting, and failure to pass meconium?
- A. Pyloric stenosis
- B. Intussusception
- C. Hirschsprung disease
- D. Celiac disease
Correct Answer: C
Rationale: Hirschsprung disease should be suspected in a newborn with abdominal distention, vomiting, and failure to pass meconium. This condition arises from a congenital absence of nerve cells in a portion of the colon, leading to severe constipation and intestinal obstruction. Pyloric stenosis typically presents with non-bilious projectile vomiting in the first few weeks of life. Intussusception classically manifests with sudden onset of colicky abdominal pain and currant jelly stools. Celiac disease may present with chronic diarrhea, failure to thrive, and abdominal distention but is less likely in this scenario.
The nurse is preparing to admit a 10-year-old child with appendicitis. What clinical manifestations should the nurse expect to observe?
- A. Fever
- B. Vomiting
- C. Tachycardia
- D. All of the above
Correct Answer: D
Rationale: Correct! Typical signs of appendicitis include fever, vomiting, and tachycardia due to infection and inflammation. These clinical manifestations are commonly observed in patients with appendicitis. Hyperactive bowel sounds are not typically associated with appendicitis, so they are not expected findings in this situation. Therefore, the correct answer is 'All of the above.'
