A nurse is caring for an infant who has coarctation of the aorta. Which of the following should the nurse identify as an expected finding?
Explanation & Rationale
Choice A reason: Frequent nosebleeds are not linked to coarctation of the aorta, a congenital aortic narrowing. They may result from hypertension or nasal issues, but coarctation causes differential blood pressure, with high upper body pressure, not nasal vasculature changes, making this an unrelated finding. Choice B reason: Weak femoral pulses are expected in coarctation of the aorta, as the narrowing restricts blood flow to the lower extremities. This creates a pressure gradient, with stronger upper body pulses, detectable in infants, guiding diagnosis and management of this cardiovascular defect. Choice C reason: Increased intracranial pressure is not associated with coarctation, which affects cardiovascular dynamics, not cranial pressure. It may occur in neurological conditions, but coarctation’s primary effect is hypertension above the narrowing, not brain-related changes, making this an irrelevant finding in this context. Choice D reason: Upper extremity hypotension is incorrect, as coarctation causes hypertension in the upper extremities due to restricted aortic flow. Blood pressure is higher above the narrowing, with strong brachial pulses, while lower extremities experience reduced flow, opposite to hypotension in the upper body.
