Reminders when working with IV solutions:1) Normal Saline is equal to 0.9% NaCl and 300mOsM2) 5% glucose is equal to 300mOsM. Question) You placed a red blood cell in a 1.1% saline solution. NaCl is impermeable to the membrane. The cell was placed in a ___
Solution
hypertonic solution.
Here's the step by step explanation:
-
The concentration of the saline solution in which the red blood cell is placed is 1.1%. This is higher than the concentration of a normal saline solution, which is 0.9% NaCl.
-
A hypertonic solution is one where the concentration of solutes is greater outside the cell than inside it.
-
Since the concentration of the saline solution (1.1%) is higher than that inside the red blood cell (which would be equivalent to a 0.9% NaCl solution), water will move out of the cell to try and balance the concentration of solutes. This is due to osmosis - the process where water moves from an area of lower solute concentration to an area of higher solute concentration.
-
Therefore, the red blood cell has been placed in a hypertonic solution.
