Explanation:
Detailed explanation-1: -Q. 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: -The effects of hypertonic NaCl. The red blood cells, therefore, lose their normal biconcave shape and shrink or crenate.
Detailed explanation-3: -The cells will not gain or lose water if placed in isotonic solution. The normal saline solution which is 0.9% NaCl is isotonic with blood. Hence, the animal cells remain unchanged.
