A nurse is caring for a client who has a prescription for phenelzine. The nurse should instruct the client to avoid which of the following over-the-counter medications?

A. "I will do my best to avoid crying in front of my loved ones."
This statement suggests the client might be trying to hide their emotions, which can lead to further emotional distress. Suppressing emotions, like crying, is not a healthy coping mechanism and can exacerbate feelings of sadness and isolation.

B. “I will stay in bed on days when I feel exhausted."
Staying in bed excessively, especially during the day, is a behavior associated with depression and can worsen depressive symptoms. Encouraging the client to maintain a regular sleep schedule and engage in activities, even if they are small, is a more beneficial approach. Physical activity and exposure to natural light can positively impact mood.

C. “I’ll use the coping mechanisms that helped me in the past."
This is the correct choice. Reverting to previously effective coping mechanisms indicates an understanding of self-awareness and the ability to recognize what has worked positively in the past. Coping mechanisms such as relaxation techniques, hobbies, social support, or therapy can be valuable tools in managing depressive symptoms.

D. “I will avoid talking about events that upset me."
Avoiding discussions about upsetting events can prevent the client from addressing and processing their emotions, hindering the therapeutic process. Encouraging open communication and expressing feelings with a trusted individual, therapist, or support group can help the client work through emotional challenges.

A. Denial:
Denial is a defense mechanism in which a person refuses to accept reality or acknowledge the existence of something that is evident to others. For example, a person diagnosed with a serious illness might deny that they are ill or refuse to believe the diagnosis. In this scenario, the client is not denying a reality; he is expressing anger and directing it toward the nurse.

B. Compensation:
Compensation is a defense mechanism where an individual overachieves in one area to compensate for real or imagined deficiencies in another area. For instance, someone who feels intellectually inferior might excel in sports to compensate for their perceived inadequacy. This is not applicable to the client's situation in the scenario provided.

C. Rationalization:
Rationalization involves providing logical or reasonable explanations to justify behaviors or feelings that might otherwise be unacceptable. For instance, a person might rationalize a failure by blaming external factors rather than accepting personal responsibility. In the scenario, the client is not offering rationalizations but is expressing direct anger.

D. Displacement:
Displacement occurs when emotions, especially anger or frustration, are redirected from the original source to a less threatening target. For example, a person who is angry with their boss might come home and take out their frustration on their family members. In the given situation, the client is displacing his anger from his partner onto the nurse, asking her to leave, making displacement the most appropriate choice.
