A nurse is caring for a preschool client who has Tetralogy of Fallot (TOF). What are the defects the nurse should be aware of when caring for a client with Teratology of Fallot (TOF)? (Select all that apply).

A. Pyloric stenosis is unrelated to TOF. It involves the narrowing of the pyloric valve in the stomach and is not a defect associated with TOF. B. LVH is not typically a feature of TOF, as the primary issues affect the right ventricle. C. Right ventricular hypertrophy occurs due to the obstruction of blood flow through the pulmonary valve in TOF. D. In TOF, the aorta is positioned directly over the ventricular septal defect (VSD), which is known as overriding aorta. E. A VSD is a key component of TOF, where there is a hole between the ventricles, allowing oxygen-poor and oxygen-rich blood to mix. F. Pulmonary stenosis (narrowing of the pulmonary valve) is one of the hallmark defects in TOF.
