Final answer:
The nurse should not remove compression stockings before assisting the client to bed because they are important for managing chronic venous insufficiency.
Step-by-step explanation:
The action that would warrant immediate intervention from the nurse is removing compression stockings before assisting the client to bed. Compression stockings are an important part of the treatment for chronic venous insufficiency as they help improve venous circulation and prevent pooling of blood in the legs. Removing the stockings can worsen the condition and lead to increased swelling and discomfort for the client.
