What finding would the nurse expect when measuring blood pressure in a client with coarctation of the aorta?

Choice A reason: Coarctation of the aorta causes narrowing, increasing upper body pressure and reducing lower body flow. Lower arm than leg blood pressure is incorrect, as the obstruction leads to higher arm pressure, requiring clarification of the condition’s hemodynamic effects. Choice B reason: Equal blood pressure in arms and legs is not expected in coarctation of the aorta, where aortic narrowing causes higher pressure in the arms due to obstruction. This is incorrect, as the condition creates a pressure gradient between upper and lower extremities. Choice C reason: Higher leg than arm blood pressure is incorrect, as coarctation of the aorta reduces blood flow to the legs, lowering leg pressure compared to arms. The nurse should expect the opposite, making this an incorrect finding for this congenital condition’s presentation. Choice D reason: Coarctation of the aorta causes aortic narrowing, increasing blood pressure in the arms (pre-obstruction) and decreasing it in the legs (post-obstruction). This is the expected finding, making it the correct choice, as it reflects the condition’s impact on blood pressure distribution.
