Explanation

The use of firearms is the most lethal method of suicide among the choices.
According to the Nelson Textbook of Pediatrics, suicide attempts involving firearms have a case fatality rate of approximately 90%.
The high lethality is due to the severe and immediate damage inflicted on vital organs, which minimizes the chance for any medical intervention or survival.

Option A: Wrist cutting has a very low lethality rate, often under 1%. It is difficult to cause fatal blood loss this way, and the slow progression allows ample time for discovery and medical help.
Option B: The lethality of taking poison is highly variable and depends on the substance, amount, and speed of medical treatment. Overall, its fatality rate is significantly lower than that of firearms, as it often allows a window for intervention.
Option D: While drowning is a very effective method of suicide if the act is completed, its overall case-fatality rate is lower than that of firearms. There remains a possibility, however small, of rescue and successful resuscitation.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Lethality of suicide methods and suicide risk assessment as background academic context rather than a clinical decision trigger.
A nurse's suicide risk assessment must include questions about the chosen method, its lethality, and the patient's access to the means.
A patient with a plan involving a firearm is at the highest level of risk and requires immediate, decisive safety interventions, such as constant observation and/or involuntary hospitalization.
What if? If a patient has a vague plan of 'taking pills' but no access to lethal quantities, the risk is still serious and requires a safety plan. However, if that same patient discloses they have access to a family member's handgun, the risk level escalates to critical, and the priority becomes immediate removal from that environment and securing the weapon.

How to Approach the Question

First, identify the core of the question, which is to find the 'most lethal' method of suicide.
Define 'lethal' in this context: it means the method with the highest probability of causing death per attempt (i.e., the highest case-fatality rate).
Analyze the options by comparing their potential for immediate, irreversible harm.
A gunshot often causes catastrophic damage to the brain or heart, leaving no time for rescue.
Wrist cutting and poisoning are typically slower processes, which creates a window of opportunity for the person to be found and for medical intervention to be successful.
Drowning is highly lethal but can be interrupted. Therefore, firearms have the highest certainty of death.
