Explanation

The use of a firearm in a suicide attempt has the highest case-fatality rate among the options provided.
According to the Nelson Textbook of Pediatrics, firearms result in death in approximately 90% of suicide attempts, making them exceptionally lethal.
The injury from a firearm is typically immediate, severe, and irreversible, offering almost no opportunity for medical intervention or survival.

Option A: Wrist cutting has a very low case-fatality rate, often estimated to be less than 2%. While a serious sign of distress, it is significantly less lethal than using a firearm.
Option B: The lethality of taking poison is highly variable depending on the substance, dose, and time to discovery, but it is generally much lower than firearms. Many overdoses are survivable with prompt medical treatment.
Option D: Drowning has a high lethality rate but is still lower than that of firearms. It requires specific environmental conditions and is not as swift or certain as a gunshot.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Suicide risk assessment and the lethality of different suicide methods as background academic context rather than a clinical decision trigger.
A primary nursing responsibility in mental health is suicide risk assessment. A key part of this is 'means restriction,' which involves identifying and limiting the patient's access to lethal methods.
When a patient is identified as high-risk, nurses must take immediate steps to ensure safety, which may include one-to-one observation, removing dangerous items, and communicating with the patient's family about securing firearms, weapons, and medications in the home.
What if a patient admits to suicidal thoughts with a plan to use a firearm, and the family confirms there is a gun in the house? The nurse's priority is to facilitate immediate hospitalization for safety and to educate the family on the critical need to remove the firearm from the home or secure it in a locked safe, inaccessible to the patient.

How to Approach the Question

First, identify the core question, which asks for the 'most lethal' method of suicide.
Define 'lethal' in this context. It refers to the method most likely to result in death (i.e., has the highest case-fatality rate).
Evaluate each option based on your knowledge of suicide methods.
Compare the options: Wrist cutting (low lethality), poison (variable/low lethality), drowning (high lethality), and gun (very high lethality).
Conclude that the use of a gun is the most certain and therefore the most lethal method among the choices.
Select the option corresponding to 'Use of gun'.
