Coarctation of the aorta causes all of the following signs except:

  • A. higher B/P in the upper extremities
  • B. right ventricular hypertrophy
  • C. legs cooler than arms
  • D. nosebleeds
Correct Answer: D

Rationale: Coarctation of the aorta is a congenital heart defect characterized by a narrowing of the aorta, the main artery carrying blood from the heart to the body. The signs of coarctation of the aorta include higher blood pressure in the upper extremities (Choice A) due to the narrowing of the aorta causing increased pressure proximal to the constriction. Right ventricular hypertrophy (Choice B) occurs as the heart works harder to overcome the obstruction in the aorta. Legs being cooler than arms (Choice C) is a result of decreased blood flow to the lower body due to the aortic narrowing. Hemodilution (Choice E) can occur as a compensatory mechanism in response to the increased blood pressure in the upper body. Nosebleeds (Choice D) are not typically associated with coarctation of the aorta but may occur due to other factors unrelated to this condition.
