A nurse is collecting data from an infant who has coarctation of the aorta. Which of the following manifestations should the nurse expect?

A. Machine-like murmur: This is a hallmark finding of patent ductus arteriosus (PDA), not coarctation. B. Severe cyanosis: Cyanosis is more typical in conditions with right-to-left shunting, not coarctation. C. Pulmonary edema: May occur in heart failure but is not a primary or specific sign of coarctation. D. Decreased blood pressure in the legs: Coarctation of the aorta causes narrowing, leading to higher BP in the upper extremities and lower BP in the legs.
