A. The solution must have an osmolarity higher than that of the organ to be transplanted.
B. The solution must have an osmolarity lower than that of the organ to be transplanted.
C. The solution must be isotonic compared to the cells of the organ to be transplanted.
D. The solution must be mixed with cells from the organ to be transplanted.
参考答案: C
本题详细解析:
The solution used to bathe organs to be used in a transplant should have an osmolarity equal to that of the organ to be transplanted and so the solution is isotonic compared to the organ’s tissues. A solution with an osmolarity higher than that of the organ to be transplanted (Choice A) would cause tissue cells to shrivel, while a solution with an osmolarity lower than that of the organ to be transplanted (Choice B) would cause organ cells to burst. There are no described protocols that indicate that the solution should be mixed with cells from the organ to be transplanted (Choice D).
