Question

Hypotonic solutions rehydrate but do not cause ________________ why?

a) Hyponatremia, because they lack sodium
b) Hyperkalemia, because they lack potassium
c) Dehydration, because they dilute body fluids
d) Edema, because they promote fluid retention

Answer 1

Hypotonic solutions rehydrate but do not cause dehydration because they dilute body fluids. The option (C) is correct.

Step-by-step explanation:

Hypotonic solutions rehydrate but do not cause dehydration because they dilute body fluids. In hypertonic solutions, the concentration of solutes is higher than the concentration of solutes in the body fluids. This causes water molecules to move out of the cells, leading to dehydration.

However, in hypotonic solutions, the concentration of solutes is lower, so water molecules move into the cells, preventing dehydration. Therefore, option (C) is correct.
