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

Choice A rationale Immediately following a femoral cardiac catheterization, the client must keep the affected leg straight and immobilized to prevent disruption of the clot/seal at the arterial puncture site. While turning may be restricted, the head of the bed elevation is also restricted (typically kept low, ≤ 30°) to maintain femoral access site integrity, which is the primary concern. Choice B rationale A critical complication post-cardiac catheterization, especially with a femoral approach, is arterial occlusion (e.g., thrombosis, pseudoaneurysm formation, or hematoma compression) distal to the puncture site. Checking the pedal pulses (as well as color, temperature, and sensation) every 15 minutes initially is essential to monitor for signs of impaired perfusion, which necessitates immediate intervention. Choice C rationale To prevent bleeding and disruption of the clot at the arterial access site in the groin, the head of the bed must remain low, typically ≤ 30°, and the affected leg must be kept straight for the prescribed duration (often 4 to 6 hours or longer). A high-Fowler's position (sitting up) causes hip and leg flexion, which increases the risk of bleeding or hematoma formation. Choice D rationale Post-catheterization, the client must maintain strict bed rest and keep the affected extremity straight and immobile for several hours to promote hemostasis at the puncture site. Performing any passive range-of-motion (ROM) would increase the risk of vascular injury, bleeding, or dislodging the clot, which could lead to severe hemorrhage.
