A nurse is teaching nursing students the physiology of congenital heart defects. Which defect results in decreased pulmonary blood flow?
- A. Atrial septal defect
- B. Tetralogy of Fallot
- C. Ventricular septal defect
- D. Patent ductus arteriosus
Correct Answer: B
Rationale: Tetralogy of Fallot results in decreased blood flow to the lungs. The pulmonic stenosis increases the pressure in the right ventricle, causing the blood to go from right to left across the ventricular septal defect. Atrial and ventricular septal defects and patent ductus arteriosus result in increased pulmonary blood flow.
