The nurse is caring for a client with multiple sclerosis. What actions does the nurse implement to increase venous return, prevent stiffness, and maintain muscle strength and endurance?

Choice A reason: Administering corticosteroids is not an action that the nurse implements to increase venous return, prevent stiffness, and maintain muscle strength and endurance because it is a medication that reduces inflammation and relieves acute exacerbations of multiple sclerosis, but does not affect the client's physical function or mobility.

Choice B reason: Turning and repositioning every 2 hours is not an action that the nurse implements to increase venous return, prevent stiffness, and maintain muscle strength and endurance because it is a nursing intervention that prevents pressure ulcers and promotes skin integrity, but does not enhance the client's circulation or muscle activity.

Choice C reason: Administering interferon is not an action that the nurse implements to increase venous return, prevent stiffness, and maintain muscle strength and endurance because it is a medication that modifies the immune system and delays the progression of multiple sclerosis, but does not improve the client's physical function or mobility.

Choice D reason: Encouraging range-of-motion exercises is an action that the nurse implements to increase venous return, prevent stiffness, and maintain muscle strength and endurance because it is a physical activity that improves the client's blood flow, flexibility, and muscle tone, as well as prevents contractures and spasticity.
