A patient has the following volumes of distribution:
deuterium oxide: 43 liters inulin: 12.1 liters Evans blue: 3 liters
Her plasma shows a freezing point depression of 0.565 degrees C. An ideal 1 OsM solution will depress the freezing point 1.86 degrees C.
1. What is the osmolarity of her body fluids?
2. How much solute (osmoles) exists in her ECF? ICF? plasma?
