A nurse is caring for a client who just returned from a cardiac catheterization. Which of the following nursing interventions should the nurse include in the client's plan of care? (Select all that apply.)

A. It is important for the client to remain in bed for a specified time (typically 4 to 6 hours) to prevent complications such as bleeding at the catheter insertion site. B. Checking peripheral pulses in the affected extremity is crucial for assessing circulation and identifying any potential complications, such as hematoma or occlusion. C. High-Fowler's position is not typically appropriate immediately after cardiac catheterization; the client should remain flat or with limited elevation to reduce stress on the insertion site. D. Keeping the hip and leg extended is important to prevent flexion at the site of catheter insertion, reducing the risk of bleeding or hematoma formation. E. Measuring vital signs is essential after a procedure like cardiac catheterization to monitor for any changes that may indicate complications; however, the frequency is typically more frequent than every 4 hours initially.
