Final answer:
The true statement about the extent of cellular injury is that nutritional status can significantly affect how cells respond to and recover from injury.
Step-by-step explanation:
The statement about the extent of cellular injury that is true is: B) Nutritional status can have a profound effect on the extent of cell injury. This is because the nutritional status of an individual affects the overall health, including the health of cells, and can influence how well cells can cope with and recover from injury. The other options provided are incorrect for various reasons. Firstly, individual variability, including factors such as genetics, age, and overall health, means that two individuals exposed to the identical stimulus may not always have the same degree of cellular injury. Secondly, It is not possible to precisely predict the point at which cell death occurs purely based on the extent of injury as various factors including the cell's repair mechanisms play a role. Finally, not all severe injuries result in irreversible cellular injury, as some cells may recover depending on the injury's nature and duration.
