(Solution document) The ultimate cause of death due to dehydration is a fluid/volume shift that causes structural changes to cells and cellular proteins.


 

42.      The ultimate cause of death due to dehydration is a fluid/volume shift that causes structural changes to cells and cellular proteins. Which of the following correctly describes the steps that lead to this lethal fluid/volume shift?

 

A.     Extracellular osm.pressure increases......which leads to an increase in total-body-water. Water then moves out of cells.

B.     A net water loss causes intracellular osm.-press. to decrease. Water then moves out of cells.

C.     A net water loss causes extracellular osm.-press. to decrease; total-body-water increases and fluid moves out of cells.

D.     A net water loss causes total-body-water to decrease and extracellular osm-press to increase. Water then moves down its' concentration gradient (out of cells) into the extracellular space.

E.     None of the above is correct.
