Final answer:
The nurse should discuss the avoidance of alcohol, the importance of maintaining a healthy exercise program, and cessation of smoking when teaching a client with bipolar disorder about taking lithium (Lithane).
Step-by-step explanation:
When teaching a client diagnosed with bipolar disorder about taking lithium (Lithane), the nurse should discuss the avoidance of alcohol, as alcohol can interact negatively with lithium and increase the risk of side effects. Additionally, the nurse should address the importance of maintaining a healthy exercise program because exercise has been shown to be beneficial for mental health and overall well-being. Lastly, the nurse should advise the client to cease smoking or at least reduce smoking, as smoking can affect the metabolism and effectiveness of lithium.
