Practice Question
A nurse is collecting data from an infant who has a large patent ductus arteriosus. Which of the following is clinical manifestations should the nurse expect?
Answer Choices:
Correct Answer:
Machine-like murmur
Rationale:
💠 A patent ductus arteriosus (PDA) is a persistent opening between the aorta and pulmonary artery that should close shortly after birth.
💠 One of the hallmark signs of PDA is a continuous, "machine-like" murmur best heard at the left upper sternal border due to turbulent blood flow.
💠 This condition can also present with bounding pulses, widened pulse pressure, and signs of heart failure if left untreated.
💠 Cyanosis and chronic hypoxemia are more common in defects causing right-to-left shunting, whereas PDA involves left-to-right shunting.
💠 Weak pulses are not characteristic of PDA; instead, pulses are often stronger or bounding due to increased stroke volume.
