After meeting with a healthcare provider, a client who is diagnosed with bipolar disorder is screaming and stomping both feet while pacing the hallway. Which action should the nurse take?

A. Instructing the client to reduce the volume of his voice may not be effective during a manic episode and could escalate the situation. B. Accompanying the client to a quiet area of the unit provides a more supportive and calming environment, allowing the client to deescalate. C. Encouraging the client to attend a support group is a positive intervention but may not be immediately effective during an agitated state. D. Administering a PRN sedative by injection may be considered, but less restrictive interventions should be attempted first to promote a therapeutic environment.
