A 39-year-old male ICU nurse presents to the PMHNP with symptoms of posttraumatic stress disorder (PTSD) after working in New Orleans during the COVID-19 pandemic.

He tries not to think about the patients who died, but he often cannot stop their faces from “popping” into his head at any time. What modality would be most appropriate for this patient presentation?
