WebThree terms—hypertonic, hypotonic, and isotonic—are used to describe whether a solution will cause water to move into or out of a cell: If a cell is placed in a hypertonic solution, there will be a net flow of water out of the cell, and the cell will lose volume. A solution will be hypertonic to a cell if its solute concentration is higher ... WebCRYSTALLOIDS OVERVIEW Oftentimes it may be very confusing, given all of the choices of crystalloid solutions, why patients are placed on certain types of fluids. The choice may seem completely arbitrary, but there is a method to it.
