Step-by-step explanation:
After a right femoral cardiac catheterization, the nurse should implement the nursing intervention of assessing the client's neurovascular status. This is important to ensure there are no complications or impairments in the blood flow, nerve function, or tissue perfusion after the procedure. The nurse should monitor the client's pulses, capillary refill, sensation, and movement in the affected limb to detect any signs of reduced blood flow or nerve damage.
