A PMHNP is treating a 9-year-old girl using Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) after she witnessed repeated domestic violence between her parents over a two-year period. The child has completed the psychoeducation, relaxation, and affective modulation components. During the first session of the trauma narrative phase, she draws a picture of her father hitting her mother but then quickly scribbles over it, saying, 'I do not want to talk about it. Daddy said it was a secret and bad things happen if you tell secrets.' Her mother, who participates in parallel parent sessions, reports that the child's nightmares have worsened over the past week. Which action by the PMHNP is MOST appropriate?
