- A. To expand extracellular fluid volume
- B. To provide concentrated dietary protein
- C. To move water rapidly into the cells

Explanation
0.9% sodium chloride is an isotonic crystalloid that expands the extracellular and intravascular fluid compartments. It does not provide protein or potassium, and it should not be assumed to move large amounts of water into cells.
