A nurse is assessing a client who has a recent diagnosis of dissociative identity disorder. The client tells the nurse, "I think my blackouts are actually caused by low blood sugar." The nurse should recognize the client is using which of the following defense mechanisms?

Choice A reason: Phenelzine is a monoamine oxidase inhibitor (MAOI) that can interact with certain foods containing tyramine, such as cheese, leading to hypertensive crisis. The client's report of dizziness after eating a grilled cheese sandwich could indicate a spike in blood pressure. Therefore, assessing blood pressure is the priority to check for this potential adverse reaction.

Choice B reason: While respiration is important, it is not typically the first vital sign affected by the dietary interaction with phenelzine. However, if blood pressure is elevated, it could lead to respiratory changes, so it should be monitored if blood pressure is abnormal.

Choice C reason: Pulse may be affected by changes in blood pressure, but it is not the most direct indicator of a hypertensive crisis. After assessing blood pressure, the nurse should also check the pulse for any irregularities.

Choice D reason: Temperature is not directly related to the symptoms of a hypertensive crisis caused by MAOI interactions with tyramine-rich foods. It is unlikely that the client's dizziness is related to a change in body temperature.

Choice A reason: Telling a client that their experience is not real can be invalidating and may damage the therapeutic relationship between the nurse and the client. It is essential to acknowledge the client's experience as real to them and provide support without reinforcing the hallucination.

Choice B reason: While it is important not to reinforce hallucinations, avoiding direct questions about the client's experience can hinder the nurse's ability to assess the client's condition fully. It is better to ask open-ended questions that allow the client to describe their experience without feeling judged.

Choice C reason: Focusing the client on reality-based activities can help distract them from the hallucinations and ground them in the present moment. Activities such as listening to music, engaging in conversation, or participating in a physical activity can help reduce the intensity of hallucinations and provide a sense of control.

Choice D reason: Conveying sympathy for the client's experience is compassionate and can help build trust. However, it is crucial to balance empathy with encouragement to engage in reality-based activities and strategies to manage the hallucinations effectively.
