A healthcare provider is assessing a newborn who has a coarctation of the aorta. Which of the following should the provider recognize as a clinical manifestation of coarctation of the aorta?

  • A. Increased blood pressure in the arms with decreased blood pressure in the legs
  • B. Decreased blood pressure in the arms with increased blood pressure in the legs
  • C. Increased blood pressure in both the arms and the legs
  • D. Decreased blood pressure in both the arms and the legs
Correct Answer: A

Rationale: The correct answer is A: Increased blood pressure in the arms with decreased blood pressure in the legs. Coarctation of the aorta causes narrowing of the aorta, leading to increased blood pressure in the arms due to the pressure build-up before the narrowing and decreased blood pressure in the legs due to reduced blood flow beyond the narrowing. This pressure difference is a classic clinical manifestation of coarctation of the aorta.

Choices B, C, and D are incorrect because they do not align with the pathophysiology of coarctation of the aorta. B is incorrect as decreased blood pressure in the arms is not typical. C is incorrect as increased blood pressure in both the arms and legs does not reflect the characteristic pressure difference caused by the aortic narrowing. D is incorrect as decreased blood pressure in both the arms and legs is not consistent with the presentation of coarctation of the aorta.
