A nurse is caring for a client who is postoperative immediately following a cardiac catheterization with a right femoral approach. Which of the following actions should the nurse take?

After femoral cardiac catheterization, frequent assessment of peripheral pulses (every 15 min for 1 hr, then per protocol) is essential to detect arterial complications such as hematoma, arterial occlusion, or pseudoaneurysm. The dressing is not routinely changed immediately postoperatively. The head of the bed should be kept at no more than 30° to prevent femoral site bleeding. Flexing the right knee is contraindicated because it can dislodge the clot at the puncture site.
