Final answer:
The nurse should consider that displacement is an emotion-focused coping strategy that temporarily protects against feelings of worthlessness and anxiety, without addressing the root cause of stress.
Step-by-step explanation:
When a nurse is planning care for a patient that uses displacement as a coping mechanism, it's crucial to understand that this strategy is a form of emotion-focused coping. Displacement involves redirecting negative emotions or reactions from the original source of stress to a more harmless or less threatening object or person. This can mitigate feelings of anxiety or worthlessness temporarily, but it doesn't address the root cause of the stress. Therefore, the nurse should consider information that relates to protecting against feelings of worthlessness and anxiety, as this is central to the nature of displacement as a coping mechanism.
