A. Low systolic blood pressure in the upper extremities and elevated systolic blood pressure in the lower extremities. – Incorrect. Coarctation of the aorta causes the opposite finding.
B. Elevated systolic blood pressure in the upper extremities and elevated systolic blood pressure in the lower extremities. – Incorrect. Blood pressure in the lower extremities is reduced due to decreased blood flow.
C. Low systolic blood pressure in the upper extremities and low systolic blood pressure in the lower extremities. – Incorrect. Coarctation of the aorta leads to hypertension in the upper body due to increased resistance.
D. Elevated systolic blood pressure in the upper extremities and low systolic blood pressure in the lower extremities. – Correct. Coarctation of the aorta causes high BP in the arms and low BP in the legs due to obstructed blood flow past the narrowing.
