Recording an upper extremities,
Assessing for the presence of femoral pulses
Observing for excessive crying
Auscultating for a cardiac murmur
The Correct Answer is A
A. Recording an upper extremity blood pressure (in the arms) compared to a lower extremity blood pressure (in the legs) can help reveal coarctation of the aorta, as the condition often results in higher blood pressure in the upper body and lower pressure in the lower body.
B. Assessing for femoral pulses is important but may not reveal coarctation of the aorta unless there is significant obstruction.
C. Excessive crying is not a specific indicator of coarctation of the aorta.
D. While a cardiac murmur can be associated with various heart conditions, it is not the most definitive assessment for coarctation of the aorta.
