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.

Correct Answer is D
Explanation
A. While anxiety and withdrawal are concerning, they may not require immediate intervention compared to behaviors that pose risks to the child or others.
B. A stable child with a concerned parent may benefit from reassurance and support, but they do not require urgent intervention.
C. Stomach pain without an apparent cause should be assessed, but it may not be as urgent as aggressive behavior that can harm others.
D. A child exhibiting aggressive behavior poses a risk to themselves and others, necessitating immediate assessment and intervention to ensure safety and manage the behavior effectively.
Correct Answer is D
Explanation
A. Preparing for immediate surgery is necessary, but the priority intervention is to ensure adequate oxygenation and blood flow through the ductus arteriosus before surgery can be performed.
B. Initiating feeding through a nasogastric tube is not a priority for an infant with this condition, as their immediate need is to address the circulatory issue rather than feeding.
C. Administering oxygen via nasal cannula may provide some relief but is not sufficient as a standalone intervention for transposition of the great vessels, which requires maintaining ductal patency to allow mixing of oxygenated and deoxygenated blood.
D. Administering prostaglandin E1 (PGE1) is the priority intervention, as it helps maintain patency of the ductus arteriosus, allowing for temporary stabilization of the infant’s condition until surgical intervention can be performed.
