A nurse is assessing a newborn for manifestations of a large patent ductus arteriosus. Which of the following findings should the nurse expect?
Weak pulses
Cyanosis with crying
Chronic hypoxemia
Systolic murmur
The Correct Answer is D
A. Weak pulses are more indicative of reduced cardiac output or other cardiac issues, rather than specifically a large patent ductus arteriosus (PDA).
B. Cyanosis with crying can occur in various conditions, but it is not a hallmark of a large PDA; it typically presents with other symptoms.
C. Chronic hypoxemia is more associated with severe heart defects or lung conditions, whereas a large PDA may present with other signs first.
D. A systolic murmur is a classic finding in large PDAs due to the left-to-right shunting of blood, making it the most expected manifestation in this scenario.
