A nurse is caring for an infant who has a congenital heart defect. Which of the following defects is associated with increased pulmonary blood flow?
Tricuspid atresia
Patent ductus arteriosus
Coarctation of the aorta
Tetralogy of Fallot
The Correct Answer is B
A. Tricuspid atresia typically leads to decreased pulmonary blood flow due to the absence of normal blood flow to the lungs.
B. Patent ductus arteriosus results in increased pulmonary blood flow because it allows blood to flow from the aorta to the pulmonary artery, increasing the volume of blood going to the lungs.
C. Coarctation of the aorta can cause decreased blood flow to the lower body, which may not directly relate to increased pulmonary blood flow.
D. Tetralogy of Fallot is characterized by decreased pulmonary blood flow due to right ventricular outflow obstruction, making it not associated with increased pulmonary blood flow.
