Final answer:
The best action for a nurse caring for a client in the manic phase of bipolar disorder is to avoid power struggles by remaining neutral. Allowing the client to set limits, providing in-depth explanations, or encouraging group activities may not be suitable due to the nature of manic symptoms.
Step-by-step explanation:
A nurse caring for a client who is in the manic phase of bipolar disorder needs to take specific therapeutic actions to ensure the safety and well-being of the client as well as to manage the symptoms effectively. The most appropriate action from the options provided would be to avoid power struggles by remaining neutral. During mania, clients may be more prone to engaging in confrontations and it is essential for the nurse to remain calm, objective, and to avoid escalating the situation.
Allowing the client to set limits for his behavior is not advisable because he may lack the insight and judgment needed during a manic episode. An in-depth explanation of nursing expectations may not be effective due to the client's possible inability to concentrate or process complex information at this time. Encouraging participation in group activities may be overwhelming for the client and could exacerbate the manic symptoms.
The priority is to maintain a therapeutic environment, and this may include setting consistent, clear, and enforceable limits with the client while using a calm and firm approach.
