Cardiovascular questions with correct answers
Surgical repair for patent ductus arteriosus (PDA) is performed to prevent which complication? - Answer A worsening of pulmonary vascular congestion A patent ductus arteriosus (PDA) allows blood to flow from the aorta (high pressure) to the pulmonary artery (low pressure). If the PDA stays open, increased pulmonary vascular congestion may occur. Increased pulmonary vascular congestion is the primary complication; pulmonary infection may occur, but it is not the priority complication. Patent ductus arteriosus involves left-to-right shunting of blood. The decreased workload on the left side of the heart is not a priority complication of a PDA. Which heart defect causes narrowing of the aortic valve? - Answer Aortic Stenosis Aortic stenosis causes narrowing of the aortic valve, which in turn results in resistance to blood flow in the left ventricle, decreased cardiac output, left ventricular hypertrophy, and pulmonary vascular congestion. Which is considered a mixed cardiac defect? - Answer Transposition of the great arteries Transposition of the great arteries permits mixing of oxygenated and unoxygenated blood in the heart. What position does the nurse caring for a young child with tetralogy of Fallot see the child assuming in an attempt to compensate for the congenital heart defect? - Answer Knees to Chest
