Extract:
A newborn with blood pressure measurements at each extremity.
Question 1 of 5
Which of the following findings suggests coarctation of the aorta?
Correct Answer: D
Rationale: The correct answer is D: Elevated systolic blood pressure in the upper extremities and low systolic blood pressure in the lower extremities. This finding is characteristic of coarctation of the aorta, a congenital heart defect where there is a narrowing of the aorta. The elevated blood pressure in the upper extremities occurs because the heart has to work harder to pump blood through the narrowed aorta, resulting in increased pressure upstream. Conversely, the lower extremities receive less blood flow due to the constriction, leading to lower blood pressure.
Choices A, B, and C do not align with the typical presentation of coarctation of the aorta and are therefore incorrect.
