Which term refers to the final cessation of bodily activity used to determine death when circulatory and respiratory functions have irreversibly ceased and the entire brain has irreversibly ceased to function?

• A. Cardiac arrest
• B. Brain death
• C. Coma
• D. Palliative care

Answer: (B)

The concept being tested is how death is defined when the brain has irreversibly ceased function. Brain death occurs when there is irreversible loss of all brain activity, including the brainstem. This means the person is legally dead even if some bodily processes can be maintained briefly with life support. That makes it the best term for describing death in the scenario where circulatory and respiratory functions have irreversibly ceased and the entire brain has irreversibly ceased to function. Cardiac arrest refers to the stopping of the heart and circulation and is not automatically death if circulation can be restored. A coma is a prolonged state of unconsciousness with variable brain activity and is not death. Palliative care focuses on comfort and quality of life, not on declaring death.
