Question

A patient involved in a car accident was transported to the hospital for a severe head injury. Upon her arrival, the doctor has given her a poor chance of survival due to the injuries she sustained. Based on his diagnosis, which part of the brain was damaged?

1) The cerebellum
2) The diencephalon
3) The cerebrum
4) The brainstem

Answer 1

A poor survival prognosis after a head injury often indicates damage to the brainstem, as it controls vital life-supporting functions.

Step-by-step explanation:

If a patient has a severe head injury with a poor chance of survival, it most likely indicates critical damage to a part of the brain that controls vital functions. Among the options provided, the brainstem is responsible for regulating essential life-supporting functions such as the cardiovascular and respiratory systems. Severe damage to the brainstem can lead to a poor prognosis due to its role in regulating heart rate, breathing, and consciousness.
