What should a nurse prioritize when creating a care plan for a client admitted with major depressive disorder exhibiting suicidal ideation?

Choice A reason: Medication adherence is vital for the long-term management of major depressive disorder; however, antidepressants often take weeks to reach therapeutic levels. In the acute phase of suicidal ideation, education about pills is secondary to preventing the client from acting on self-destructive impulses in the immediate present. Choice B reason: Group therapy sessions provide peer support and help reduce social isolation, which are important components of psychiatric rehabilitation. However, a client with active suicidal ideation may be too unstable or withdrawn to participate meaningfully, and these sessions do not provide the high level of security required. Choice C reason: Patient safety is the absolute priority in psychiatric nursing. One-to-one supervision (constant observation) and rigorous environmental safety checks to remove potential ligatures or sharps are the most effective immediate interventions to prevent self-harm and ensure the client remains alive to receive further therapeutic treatment. Choice D reason: While depressed clients often suffer from nutritional deficits or weight changes, dietary coordination is a lower-level priority on Maslow's hierarchy compared to immediate physical safety. Addressing nutritional needs is part of holistic care but only after the immediate risk of suicide has been mitigated.
