Final answer:
The nurse can use interventions such as providing emotional support, education about the diagnosis, and exploring coping mechanisms to help a client with anxiety related to a terminal illness.
Step-by-step explanation:
The nurse can use several interventions to help a client with anxiety related to a terminal illness. One intervention is to provide emotional support and create a safe and nonjudgmental environment for the client to express their fears and concerns. This can be done through active listening, empathy, and validation of the client's feelings. Another intervention is to provide education about the client's diagnosis and the progression of the illness, which can help reduce anxiety by increasing the client's understanding and control over the situation. Additionally, the nurse can explore coping mechanisms with the client and help them develop and implement effective strategies to manage their anxiety, such as deep breathing exercises, relaxation techniques, and engaging in activities that promote positive emotions and distract from negative thoughts.
