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?
Upper extremity hypotension
Weak femoral pulses
Frequent nosebleeds
Increased intracranial pressure
The Correct Answer is B
A. Coarctation of the aorta typically results in hypertension in the upper extremities due to increased pressure proximal to the coarctation.
B. Weak or absent femoral pulses are characteristic findings in coarctation of the aorta due to reduced blood flow to the lower extremities beyond the coarctation. This finding indicates peripheral vascular compromise in the lower limbs.
C. Frequent nosebleeds are not typically associated with coarctation of the aorta.
D. Coarctation of the aorta does not directly affect intracranial pressure.
