Persistent cyanosis has led an infant's care team to suspect a congenital heart defect. Which of the following assessment findings would suggest coarctation of the infant's aorta?
A) The child has a split S2 heart sound on auscultation.
B) ECG reveals atrial fibrillation.
C) The child experiences apneic spells after feeding.
D) Blood pressure in the child's legs is lower than in the arms.
Ans: D
Feedback:
The classic sign of coarctation of the aorta is a disparity in pulsations and blood pressures in the arms and legs. In coarctation, the pressure in the legs is lower and may be difficult to obtain. A split S2, dysrhythmias, and apneic spells are not characteristics of coarctation of the aorta.
