What statement by a client with PTSD requires immediate intervention?

The statement indicating that the client "cannot stop the nightmares, even the medicine does not work" requires immediate intervention because it reflects a severe symptom of PTSD that can significantly impact the client's quality of life and mental health. Nightmares are a common distressing symptom of PTSD, and when a client reports that they are not finding relief even with medication, it suggests that their condition may be worsening or that they are struggling to cope effectively.

In this instance, the client may be experiencing persistent and debilitating thoughts and nightmares that can lead to increased anxiety, depression, and potential self-harm if not addressed promptly. Immediate intervention by the nursing staff or mental health professionals can facilitate a reassessment of the treatment plan, explore alternative therapeutic options, and ensure comprehensive support for the client's mental health needs.

The other statements, while indicative of challenges faced by individuals with PTSD, do not signal an immediate need for intervention in the same way. Feeling tired may reflect general exhaustion rather than acute distress, forgetfulness can occur for many reasons and may not be immediately dangerous, and increasing therapy sessions suggests a proactive approach to managing symptoms. Therefore, the urgency of addressing persistent nightmares emphasizes the need for immediate support and intervention.
