Question 1 of 5
After teaching a class about the hemodynamic characteristics of congenital heart disease, the instructor determines that the teaching has been successful when the class identifies which defect as an example of a disorder involving increased pulmonary blood flow?
Correct Answer: C
Rationale: The correct answer is C: Patent Ductus Arteriosus (PD
A). PDA is a congenital heart defect where the ductus arteriosus, a fetal blood vessel between the pulmonary artery and aorta, fails to close after birth. This results in increased pulmonary blood flow, as oxygen-rich blood from the aorta flows back into the pulmonary artery. This leads to pulmonary congestion and potential complications.
Transposition of The Great Arteries (
A) involves abnormal positioning of the aorta and pulmonary artery, leading to mixing of oxygenated and deoxygenated blood without increased pulmonary blood flow. Coarctation of the Aorta (
B) is a narrowing of the aorta, leading to increased systemic blood pressure but not affecting pulmonary blood flow. Tetralogy of Fallot (
D) involves decreased pulmonary blood flow due to a combination of defects.
