A nurse is caring for a client who has obsessive-compulsive disorder (OCD). Which of the following actions is appropriate for the nurse to take?

A. Use negative reinforcement techniques to prevent the client from performing rituals: Negative reinforcement is not a therapeutic or evidence-based approach for managing OCD. B. Determine the client's level of anxiety: Anxiety levels often influence compulsive behaviors. Assessing the client's anxiety helps guide interventions to manage it effectively. C. Encourage avoidance of situations that increase anxiety: Avoidance reinforces the OCD cycle and is not a constructive coping strategy. D. Interrupt the compulsive behavior: Abruptly interrupting rituals can increase the client’s anxiety and distress.
