What is the best course of action for a nurse if a patient with major depression suddenly appears happy and peaceful after expressing suicidal thoughts?

Choice A reason: Encouraging socialization may be premature and dangerous if the client has developed a suicide plan. While peer interaction is eventually therapeutic, the sudden mood shift suggests a high risk of self-harm, and placing the client in a social setting without close supervision could provide an opportunity to act on those impulses. Choice B reason: Celebrating an improved mood is a dangerous clinical error in this context. A sudden shift from deep depression to peace often indicates that the client has resolved the internal conflict by finalizing a suicide plan. This "relief" stems from the decision to end their life, necessitating immediate intervention rather than celebration. Choice C reason: Preparing discharge paperwork is contraindicated when a client displays signs of imminent suicide risk. The period of "improvement" is often when clients have the energy and clarity to carry out a plan. Discharge should only occur after a comprehensive safety evaluation confirms the client is no longer a danger to themselves. Choice D reason: A sudden, unexplained lift in mood is a classic "red flag" in psychiatric nursing. The nurse must perform a focused reassessment for suicidal ideation, intent, and access to means. Promptly communicating these findings to the multidisciplinary team ensures that safety protocols, such as increased observation or 1-to-1 sitting, are implemented.
