A nurse is providing care for a client who has anorexia nervosa. Which of the following nursing interventions should the nurse take?

A. Lithium: Lithium is a mood stabilizer commonly used in the treatment of bipolar disorder. It helps to control mood swings and prevent the recurrence of manic and depressive episodes.

B. Carbamazepine: Carbamazepine is an anticonvulsant medication that has been found effective in managing mood swings in bipolar disorder. It can help stabilize mood and prevent manic episodes.

C. Valproate (Valproic acid or Divalproex sodium): Valproate is another anticonvulsant medication that is used as a mood stabilizer in bipolar disorder. It can help control manic and mixed episodes.

The following options are not used to treat bipolar disorder:

D. Paroxetine: SSRIs, including paroxetine, carry a risk of inducing mania or hypomania in individuals with bipolar disorder. This risk is why these medications are usually avoided or used cautiously, always in conjunction with a mood stabilizer like lithium, valproate, or atypical antipsychotics. Before initiating paroxetine, it’s crucial that the client is stabilized with a mood stabilizer to minimize the risk of mood switching (i.e., moving from depression to mania or hypomania).

E. Donepezil: Donepezil is a medication used to treat Alzheimer's disease and other forms of dementia. It is not used to treat bipolar disorder.

A. "I can see that you trust me, but you should share those feelings with your psychiatrist, not me."

While encouraging the client to discuss their feelings with a mental health professional is important, this response does not address the immediate safety concern presented by the client's intent to harm others.

B. "I will not violate our nurse-client relationship. The information we discuss will remain confidential between us."

This response is inappropriate because it implies that the nurse will keep the information confidential, even though the client's statement raises concerns about the safety of others.

C. "Because you are a minor, I have to share any information that I feel is important with your parents."

While parents may have the right to be informed about their minor child's well-being, this situation goes beyond parental involvement. The nature of the threat requires immediate intervention from appropriate professionals and authorities.

"D. I cannot promise that. I must share this information with other members of the team who are responsible for planning your care."

Explanation: The client's statement about having a desire to harm others, especially classmates and a school teacher, raises significant concerns about the safety and well-being of not only the client but also the potential victims. In cases where the client poses a risk of harm to themselves or others, the nurse has a duty to breach confidentiality to ensure the safety of all involved parties. This response conveys the nurse's ethical obligation to involve other members of the treatment team and appropriate authorities to address the potential threat.
