Initially a Child with a Ventricular Septal Defect (VSD)and Pulmonic

question 19

Multiple Choice

Initially a child with a ventricular septal defect (VSD) and pulmonic valve stenosis is acyanotic.Over time,however,the pulmonic valve stenosis worsens and the child becomes cyanotic.What is the most probable explanation?

• A) The child becomes severely anemic and hypoxemic.
• B) The pulmonic stenosis elevates right ventricular pressure, thereby shunting unoxygenated blood from the right ventricle into the left ventricle; unoxygenated blood is then pumped to the systemic circulation.
• C) Blood is shunted from the left ventricle into the right ventricle.
• D) Excess blood in the right ventricle and pulmonary artery fills the alveoli, thereby causing hypoxemia and cyanosis.
