Detailed explanation-1: -0.9% NaCl is isotonic to red blood cells. Which of these describes what will happen if a technician misplaces a decimal point and makes 9.0% NaCl solution instead and administers it to a patient? The cells exposed to the solution will burst.
Detailed explanation-2: -Answer and Explanation: Red blood cells are isotonic with 0.9% solution of sodium chloride. If the cell is isotonic with NaCl solution, nothing will happen with regards to solvent (water) movement in the cell.
Detailed explanation-3: -Answer and Explanation: If 0.9% NaCl were isotonic to a cell then anything greater than 0.9% would be hypertonic. A hypertonic solution is one which has a greater concentration of dissolved solutes while an isotonic one has a similar concentration of solutes.
Detailed explanation-4: -The effects of hypertonic NaCl. The red blood cells, therefore, lose their normal biconcave shape and shrink or crenate.
