A nurse is caring for a client who is recovering from a substance use disorder and is preparing to be discharged. Which of the following factors should the nurse identify as a barrier to recovery?

Choice A reason: Living in a hallway shelter may reflect unstable housing, which is a risk factor for relapse, but it is not as direct a barrier as residing with someone actively using substances. Choice B reason: Restlessness and poor sleep hygiene are symptoms that may complicate recovery but are not primary barriers unless they interfere with treatment adherence. Choice C reason: Identifying triggers is a protective factor, not a barrier. It shows insight and readiness for relapse prevention planning. Choice D reason: Staying with someone who is actively using substances creates a high-risk environment for relapse and undermines recovery efforts. This is a direct and significant barrier.
