A nurse is caring for a client who has a defect that allows blood flow from the left side to the right side of the heart through an abnormal connection. Which of the following defect results in increased pulmonary blood flow?
Tricuspid atresia
Pulmonic stenosis
Ventricular Septal Defect
Transposition of the great arteries
The Correct Answer is C
A. Tricuspid atresia causes underdevelopment of the right side of the heart and does not result in increased pulmonary blood flow.
B. Pulmonic stenosis causes obstruction of blood flow to the lungs, not an increase in blood flow.
C. A ventricular septal defect (VSD) is a congenital heart defect that allows blood to flow from the left ventricle to the right ventricle, increasing blood flow to the lungs and causing pulmonary congestion.
D. Transposition of the great arteries results in two separate circulations, one for oxygenated and one for deoxygenated blood, and does not increase pulmonary blood flow
