A 30-year-old male patient, John, presents to the clinic with his wife. She reports that John has been experiencing periods of extreme energy and euphoria, followed by episodes of deep depression over the past several months. During his manic episodes, John engages in risky behaviors such as excessive spending and reckless driving. During his depressive episodes, he isolates himself and has expressed feelings of hopelessness. Based on this scenario, what is the priority nursing action for John?

Choice A reason: While mood stabilizers are essential in treatment, medication cannot be safely administered before completing an assessment of risk and safety. Choice B reason: The priority in this scenario is to assess safety, as John is at risk of harming himself or others due to reckless behavior during mania and suicidal ideation during depression. Safety always precedes treatment or education. Choice C reason: Therapy is a valuable part of long-term management, but it is not the immediate priority when safety concerns exist. Choice D reason: Education is important but cannot come before determining immediate risk and ensuring safety.
