The resident, knowing what Ed had done, infused the patient with 1 L of a 600 mM (i.e., 600 mOsm / L) sucrose solution. Knowing that, after Edâs treatment, the patientâs plasma volume was 3.6L, her RBC volume was 2.4L, and her osmolarity was 250 mOs/ L. Assume that this infusion equilibrated with Ms. M.B.âs plasma and RBCs.
6.Predict (increase, decrease, no change) the effect of the infusion given by the resident on the parameters listed. Explain your predictions.
Parameter: a. Ms. M.B.âs RBC osmolarity -------> Predictions:
b. Ms. M.B.âs volume -------------------> Predictions:
Please and thank you!!!
Ed Rivers, a third-year medical student, was alone in the hospital emergency room one night. It was unusually quiet in the ER, so the residents were getting some much-needed sleep. A patient, Ms. B., was brought in showing signs of serious dehydration. Ed tried to give her water but she vomited. Feeling that he must try something else and not wanting to wake the residents, he administered 1 liter (L) of sterile distilled water intravenously (IV).
The questions that follow are aimed at determining the consequences of Eds action. Assume for simplicity that red blood cells (RBC) contain only solutes to which the RBC membrane is impermeable. The osmolarity of the RBC, the concentration of solute particles, is 300 mOsm/L.
