What nursing assessments are critical after cardiac catheterization?

After cardiac catheterization, assess the access site, usually the femoral or radial artery, for bleeding, hematoma formation, and signs of pseudoaneurysm. Check distal pulses, sensation, temperature, and color of the affected extremity to detect arterial occlusion. Monitor vital signs frequently, especially blood pressure and heart rate. Maintain the affected extremity straight and immobile for the prescribed time if femoral access was used. Encourage fluid intake to flush contrast dye and prevent nephropathy. ---
