Initiate an involuntary psychiatric hold. A recent suicide attempt establishes imminent danger to self, and the patient's current denial and desire to leave do not override the clinical assessment of risk.
This is correct. A recent suicide attempt by overdose is strong evidence of imminent danger to self. The patient's current verbal reassurance and desire to leave do not negate this risk — in fact, denial, minimization, and eagerness to leave after a suicide attempt may themselves be risk factors. The PMHNP should initiate an involuntary psychiatric hold for evaluation, as the patient meets criteria: mental health crisis (suicide attempt) and imminent danger to self. The hold allows for a thorough psychiatric evaluation, risk assessment, safety planning, and determination of appropriate level of care.
