Which example corresponds to vital organ failure?

Vital organ failure refers to the dysfunction of critical organs required for sustaining life. The central nervous system (CNS) is a major component of the body that controls vital functions, including consciousness, movement, and sensory processing. When there is failure in the central nervous system, such as in conditions like a stroke or severe traumatic brain injury, it can lead to significant life-threatening situations, impacting the patient's ability to survive.

Cardiac arrest refers to the heart ceasing to function, which is indeed critical, but it is more accurately termed cardiac failure rather than directly central nervous system failure. While a fractured bone and chronic pain are serious medical concerns, they do not constitute organ failure. They pertain to structural issues and discomfort rather than the dysfunction of an organ system. Thus, the option indicating central nervous system failure accurately reflects an example of vital organ failure.
