Hypotonic Fluids pull fluid into which space?

Hypotonic Fluids pull fluid into which space?

• A. Pull fluid into bloodstream
• B. Indicate fluid in alveoli
• C. Expand vascular volume
• D. Move fluid into cells

Answer: (A)

Osmosis and osmolality differences drive where water moves. Hypotonic fluids have lower osmolality than plasma, so water shifts from the extracellular space into cells to balance solute concentrations. The result is fluid moving into the intracellular compartment, causing cells to swell. This is why the space affected is inside the cells. They don’t primarily pull fluid into the bloodstream or expand vascular volume, and they don’t specifically indicate fluid in the alveolar spaces. In excess, this can lead to cellular edema and hyponatremia.
