Concentration of sucrose, Tina administered 1 liter of | Homework Help
Tina administered 1 liter of sterile distilled water IV to a patient. Predict the direction (increase, decrease, no change) you would expect Tina’s infusion to have produced in these parameters, and explain your predictions. Assume that red blood cells contain only solutes to which the rbc membrane is impermeable and that rbcs and plasma are in osmotic equilibrium when patient is brought in. The osmolarity of the rbc is 300 mOsm/L
The patient got worse after Tina’s treatment. When blood was drawn, the supernatant above the packed rbcs was pink. The patient was then infused with a sucrose solution . ( the rbc membrane is impermeable to sucrose)
Why was the plasma pink and what concentration of sucrose solution should Tina administer to leave the patient’s rbc volume unaffected?
