The nurse is conducting a staff in-service on congenital heart defects. Which structural defect constitutes tetralogy of Fallot?
- A. Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy
- B. Aortic stenosis, ventricular septal defect, overriding aorta, 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.
