Persistent vegetative state (PVS) is not considered death under UDDA because:

Persistent vegetative state (PVS) is not considered death under UDDA because:

• A. PVS is considered death
• B. UDDA declares PVS as death
• C. PVS is not considered death under UDDA
• D. PVS has no brain activity

Answer: (C)

UDDA defines death as either irreversible cessation of all brain functions (including the brainstem) or irreversible cessation of circulatory and respiratory functions. In a persistent vegetative state, the patient has lost conscious awareness, but brainstem and other brain functions continue, and some brain activity persists. Because there is not an irreversible cessation of all brain functions, it does not meet the brain-death criterion. It also does not automatically meet the circulatory/respiratory criterion unless those functions have irreversibly ceased. So, persistent vegetative state is not considered death under UDDA.
