ATI Nursing Care of Children 2019 B

Correct Answer: A

Rationale: The correct answer is A, Patent ductus arteriosus. This condition is characterized by a continuous 'machine-like' murmur due to abnormal blood flow between the aorta and pulmonary artery. Ventricular septal defect (choice B) is characterized by a harsh holosystolic murmur, atrial septal defect (choice C) typically presents with a fixed split S2 and a pulmonary flow murmur, and coarctation of the aorta (choice D) is associated with a systolic murmur in the back and bilateral lower extremities.

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.

Correct Answer: A

Rationale: The most appropriate action for the nurse to take in this situation is to notify the healthcare provider immediately. This is important as the removal of the NG tube can disrupt postoperative care, especially in terms of maintaining gastric decompression. Inserting a new NG tube without practitioner direction can be unsafe and is not within the nurse's scope of practice. Similarly, replacing the NG tube or leaving it out should be decided by the healthcare provider to ensure the infant's safety and appropriate postoperative care.

Correct Answer: C

Rationale: The correct answer is to administer epinephrine. Administering epinephrine is the crucial first step in managing anaphylaxis as it helps reverse the severe allergic reaction by constricting blood vessels and relaxing airway muscles, preventing a life-threatening situation. Antihistamines (Choice A) are not the first-line treatment for anaphylaxis and should not delay the administration of epinephrine. Establishing IV access (Choice B) may be necessary but is not the initial step in managing anaphylaxis. Monitoring vital signs (Choice D) is important but should not take precedence over administering epinephrine in the acute management of anaphylaxis.

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.
