- A 5% dextrose is isoosmotic to plasma. What effect would infusion of 1L of a 5% dextrose solution have on ECF and ICF volumes? How it would affect body fluid osmolality of a 70 kg individual and why?Estimate the total osmolarity of a 2-in-1 TPN bag containing D14W AA 6% plus 160 mEq KCI and 140 mEq NaCl of electrolytes in a total volume of 2 liters. Express final answer in terms of mOsm/LA 68-year-old lady with bowel cancer who had been admitted to hospital following a fall had a persistent low plasma sodium including the following plasma results (refer- ence ranges are given in brackets): Sodium Potassium Urea Creatinine Glucose Osmolality 120 mmol/L 3.9 mmol/L 3.4 mmol/L 53 μmol/L 5.2 mmol/L 255 mOsm/kg (135-145) (3.5-5.0) (3.5-6.6) (70-150) (3.5-5.5) (285-305) In this patient, the urine volume was low and relatively concentrated, the urine osmo- lality was 374 mOsm/kg and its sodium concentration was 75 mmol/L.
