Pediatric Cardiovascular Disorders Nursing Questions
Question 1 of 5
The nurse is conducting a staff in-service on congenital heart defects. Which structural defect constitutes tetralogy of Fallot?
Correct Answer: A
Rationale: Tetralogy of Fallot has these four characteristics: pulmonic stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. There is pulmonic stenosis but not atrial stenosis in tetralogy of Fallot. Right ventricular hypertrophy, not left ventricular hypertrophy, is present in tetralogy of Fallot. Tetralogy of Fallot has right ventricular hypertrophy, not left ventricular hypertrophy, and an atrial septal defect, not aortic hypertrophy.
Question 2 of 5
The nurse is talking to a parent of an infant with heart failure about feeding the infant. Which statement about feeding the child is correct?
Correct Answer: A
Rationale: The metabolic rate of infants with heart failure is greater because of poor cardiac function and increased heart and respiratory rates. Their caloric needs are greater than those of the average infants, yet their ability to take in the calories is diminished by their fatigue. Infants with heart failure should be fed every 3 hours; a 2-hour schedule does not allow for enough rest, and a 4-hour schedule is too long. Fluids must be carefully monitored because of the heart failure. Infants do not require supplemental oxygen with feedings.
Question 3 of 5
Which should the nurse consider when preparing a school-age child and the family for heart surgery?
Correct Answer: B
Rationale: The child and family should be exposed to the sights and sounds of the intensive care unit (ICU). All positive, nonfrightening aspects of the environment are emphasized. The child should be shown unfamiliar equipment and its use demonstrated on a doll. Carefully prepare the child for the postoperative experience, including intravenous (IV) lines, incision, and endotracheal tube.

Question 5 of 5
Which therapeutic management should the nurse expect to implement for a child with rheumatic fever?
Correct Answer: A
Rationale: The goal of medical management is the eradication of the hemolytic streptococci. Penicillin is the drug of choice. Salicylates can be used to control the inflammatory process, especially in the joints, and reduce the fever and discomfort. Bed rest is recommended for the acute febrile stage, but it does not need to be strict. The chorea is transient and will resolve without treatment.
