Final answer:
The goal of performing passive range of motion (ROM) and splinting is to prevent joint contractures, which is the correct indicator of goal achievement for the nurse's interventions.
Step-by-step explanation:
When a nurse is performing passive range of motion (ROM) and splinting, the primary goal of these interventions is to maintain joint flexibility and integrity. The correct answer to this specific question is the prevention of joint contractures, which is a common complication in patients who are immobile or at risk due to various health issues. These contractures can result from prolonged immobilization, leading to shortening of muscles and tendons around a joint, hence limiting the movement and function of the joint. Performing ROM exercises helps maintain joint and muscle flexibility, thereby preventing contractures. Splinting also plays a role in maintaining a functional position and reducing the risk of contractures. Therefore, the goal achievement for the nurse's action would be indicated by the successful prevention of joint contractures.
