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 ["B","C","E"]
Explanation
A. Cyanosis of the lips and tongue is not a typical finding in coarctation of the aorta; rather, it is more associated with cyanotic congenital heart defects.
B. Weak or absent femoral pulses are expected due to reduced blood flow to the lower body, as the coarctation typically occurs distal to the left subclavian artery.
C. Bounding pulses in the upper extremities are common because the blood flow to the upper body is increased, leading to stronger pulses.
D. High blood pressure in the lower extremities is not typical; instead, there is often lower blood pressure in the lower body due to the obstruction.
E. Poor feeding and irritability are common symptoms in infants with heart conditions, as they may be in distress or not getting enough blood flow to meet their metabolic needs.
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.
