A nurse is planning care for a client who recently attempted suicide. Which of the following actions should the nurse plan to take?

Clients who have recently attempted suicide are at high risk for self-harm and require close supervision and strict safety precautions. Nursing care focuses on maintaining a safe environment, preventing access to means of self-injury, and ensuring compliance with prescribed treatments. Safety measures include direct observation, environmental modification, and careful monitoring of medications and personal items. These interventions aim to reduce opportunities for further self-harm during the acute risk period. Rationale: A. Observing the client's behavior every 2 hours is insufficient for a high-risk suicidal client. Such clients typically require continuous or close one-to-one observation depending on risk level. Intermittent monitoring may allow opportunities for self-harm to go unnoticed. B. Keeping the client's door shut when they are in the room is unsafe because it prevents continuous observation and rapid intervention in case of self-harm behavior. Suicide precautions require visibility and easy access to the client to ensure safety and timely response. C. Ensuring the client swallows each dose of medication is appropriate because it prevents cheeking or hoarding of medications that could later be used for self-harm. This is a key safety intervention in suicidal clients to ensure medications are taken as prescribed and not misused. D. Limiting personal toiletries in the client's room to cologne is incorrect because even cologne bottles can contain alcohol and glass components that may be used for self-harm. Suicide precautions require removal of potentially harmful items and strict control of all personal belongings, not selective retention of unsafe items.
