Coarctation of the aorta demonstrates few symptoms in newborns. What is a important assessment to the nurse make on all newborns to help reveal this condition?

The correct answer is A: Recording an upper extremities. Coarctation of the aorta can lead to decreased blood flow to the lower extremities, causing weaker or absent femoral pulses. By assessing the upper extremities, the nurse can detect any significant blood pressure difference between the upper and lower extremities, which is a key indicator of coarctation of the aorta. Assessing for the presence of femoral pulses (choice B) is important but may not always reveal the condition if collateral circulation is present. Observing for excessive crying (choice C) is not a specific assessment for coarctation of the aorta. Auscultating for a cardiac murmur (choice D) may not always be present in newborns with coarctation of the aorta.
