The diagrams represent various states of abnormal hydration. In each diagram, the normal state (solid lines) is superimposed on the abnormal state (dashed lines) to illustrate the shifts in the volumes (width of rectangles) and total osmolarities (height of rectangles) of the extracellular fluid and intracellular fluid compartments.

-Which of the diagrams would represent the changes (after osmotic equilibrium) in extracellular and intracellular fluid volumes and osmolarities after infusion of 3.0% sodium chloride (molecular weight of dextrose = 58.5 g/mol)?

Quizplus · Accepted Answer

Infusion of 3.0% sodium chloride, a hypertonic solution, will cause water to move out of cells into the extracellular fluid, increasing extracellular fluid volume and osmolarity while decreasing intracellular fluid volume and increasing its osmolarity.
