Attempt to reach the patient immediately by phone. Assess their emotional state, provide closure, and reschedule. If the patient is in distress and unreachable, assess whether a welfare check is warranted.
This is the correct response. The PMHNP should immediately attempt to contact the patient through a backup communication method (telephone). Once contact is established, the priority is assessing the patient's current emotional state given the abrupt interruption during trauma processing, providing emotional grounding and closure rather than attempting to resume the trauma work, and scheduling a follow-up session. If the patient cannot be reached and was in significant distress, the PMHNP should evaluate whether a welfare check is warranted based on the patient's risk level and emotional state at disconnection.
