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?

A. Chronic hypoxemia: PDA causes left-to-right shunting, which increases pulmonary blood flow but usually does not cause hypoxemia unless complications develop. B. Weak pulses: Pulses are often bounding due to increased stroke volume and decreased diastolic pressure. C. Machine-like murmur: A continuous "machinery" murmur heard at the upper left sternal border is characteristic of PDA. D. Cyanosis with crying: Cyanosis is more typical of right-to-left shunting congenital heart defects, not PDA.
