The osmolarity of the rbcs and plasma after equilibration?

year medical student was alone in the hospital ER one night. It was unusually quie Show more Ed Rivers a 3 rd year medical student was alone in the hospital ER one night. It was unusually quiet that night and the resident was getting some much needed sleep. A patient Mrs. X was brought in showing signs of serious dehydration. Ed tried to give here water but she vomited this back up. Feeling he must try something and not wanting to wake the resident Ed administered 1 liter of sterile distilled water IV. Assume for simplicity that the red blood cells contain only solutes to which the rbc membrane is impermeable and that the rbcs and plasma are in osmotic equilibrium when the patient is brought in. The osmolarity of the rbc is 300 mOsm/L. 1. Predict the direction (increase decrease no change) you would expect Eds infusion to have produced in these parameters and explain your predictions in terms of what you know from lecture and lab. a. Mrs. Xs plasma osmolarity after the infusion Prediction: Why? b. Mrs. Xs rbc volume after the infusion equilibrates with blood? Prediction: Why? c.
