A nurse is caring for a client who has bipolar disorder. The client yells at the nurse whenever medication changes are prescribed by the client's provider. The nurse should identify that the client is using which of the following defense mechanisms?

Displacement is a defense mechanism where a person redirects their emotional impulses, such as anger or frustration, from the original source to a less threatening or more accessible target. In this scenario, the client is redirecting their anger towards the nurse when medication changes are prescribed by the provider. The nurse becomes the target of the client's anger, even though the nurse is not directly responsible for the medication changes. Conversion is a defense mechanism where psychological distress is expressed as physical symptoms or ailments. Splitting is a defense mechanism where a person sees things as either all good or all bad, with no middle ground or ambivalence. Sublimation is a defense mechanism where unacceptable impulses or behaviors are channeled into socially acceptable and constructive outlets.
