A nurse is caring for a client who states, “I did not take my medication because my partner forgot to remind me.” The nurse should identify that the client is demonstrating which of the following defense mechanisms?

Choice A reason: Rationalization involves justifying behavior with logical excuses, not blaming others. The client attributes their failure to their partner, which is projection, making this incorrect for the defense mechanism. Choice B reason: Projection involves attributing one’s own shortcomings, like forgetting medication, to another person, such as the partner. The client blames their partner, making this the correct defense mechanism. Choice C reason: Repression is unconsciously blocking distressing thoughts, not blaming others. The client openly acknowledges the missed medication, so this is incorrect for the observed behavior. Choice D reason: Regression involves reverting to childish behaviors, not blaming others. The client’s statement reflects externalizing responsibility, fitting projection, making this incorrect for the defense mechanism.
