A real-life problem of permeability: The 100-mile Leadville CO ultramarathon (elevations from 9200-12,600 ft) is being held on a very hot day and you are running the medical tent. A runner is brought in unconscious and with severe dehydration. You have Nursing Assistants that know how to do IV’s, but you have to decide what to give the ailing runner. Your choices (all in sterile IV bags) are: a) 0.15 M NaCl in sterile water, b) 0.3 M NaCl in sterile water, c) 0.3 M glucose in sterile water, and d) pure, sterile H2O. Which would you choose and why? (Include the normal osmotic concentration of blood plasma in your answer.) What would happen to the runner if you gave them the other 3 options?
