A nurse is caring for a client who has factitious disorder. The client states, "I am so tired of living like this. Maybe I should just end it all." Which of the following actions should the nurse take?

A. Assess the client for suicidal ideation and thoughts of self-harm. The client's statement about feeling tired of living and contemplating ending it all indicates a potential risk for suicide. It is essential for the nurse to conduct a thorough assessment of the client’s mental state, including any suicidal thoughts or plans, to ensure their safety. B. Determine if the client has entered one of their alter personalities. This action is not relevant to factitious disorder, as it involves intentionally producing or feigning symptoms rather than dissociative identity disorder, which features the presence of distinct personality states. C. Encourage the client to use relaxation techniques. While relaxation techniques can be beneficial for managing stress, they do not address the immediate risk of suicidal ideation and should not be prioritized over a safety assessment. D. Encourage the client to participate in group therapy sessions. While group therapy can be beneficial, it may not be appropriate to encourage participation until the client's safety is ensured. Assessing for suicidal thoughts takes precedence to address any immediate risk to the client.
