The nurse finds that an infant has stronger pulses in the upper extremities than in the lower extremities, and higher blood pressure readings in the arms than in the legs. Which assessment will the nurse perform next on this infant?
1. Pedal pulses
2. Pulse oximetry level
3. Hemoglobin and hematocrit values
4. Blood pressure of the four extremities
Correct Answer: 4
Rationale: Coarctation of the aorta can present with stronger pulses in the upper extremities than in the lower extremities and higher blood pressure readings in the arms than in the legs because of obstruction of circulation to the lower extremities. Blood pressure values of the four limbs should be the next assessment data collected. Pedal pulses, pulse oximetry, and labs themselves will not provide the data needed.
