Which preservation solution is most commonly used for kidney transplants?
A) University of Wisconsin (UW) solution
B) Saline solution
C) Glucose solution
D) Distilled water
A
Explanation: The UW solution is widely used due to its efficacy in reducing ischemic injury in
kidney transplants.
How does the composition of preservation solutions affect organ viability?
A) It increases organ weight.
B) It stabilizes cellular membranes and reduces metabolic demands.
C) It promotes rapid cell growth.
D) It enhances immune responses.
B
Explanation: The composition of preservation solutions stabilizes cellular structures and reduces
metabolic activity, protecting the organ.

What is the function of antioxidants in preservation solutions?
A) To increase tissue temperature
B) To promote cell division
C) To reduce oxidative stress during ischemia-reperfusion
D) To thicken cellular membranes
C
Explanation: Antioxidants help mitigate oxidative stress that can occur during reperfusion.
What is the primary purpose of organ preservation solutions?
A) To stimulate rapid cell division
B) To reduce cellular metabolism and prevent ischemic injury
C) To increase organ size
D) To enhance enzymatic activity
B
Explanation: Preservation solutions lower cellular metabolism and reduce ischemic injury during
organ storage.
Which component in preservation solutions helps prevent cell swelling?
A) Osmotic agents like mannitol
B) High glucose content
C) Elevated salt levels
D) Increased enzyme concentration
, Page 3 of 30
A
Explanation: Osmotic agents such as mannitol help prevent cellular edema during preservation.
What role does histidine play in some preservation solutions?
A) It acts as an oxygen donor.
B) It buffers pH levels during preservation.
C) It increases cellular metabolism.
D) It stimulates tissue growth.
B
Explanation: Histidine is used in preservation solutions to help buffer pH, maintaining an
optimal environment.
Which ingredient is commonly included in preservation solutions to maintain osmotic
balance?
A) Urea
B) Lactobionate
C) Hemoglobin
D) Collagen
B
Explanation: Lactobionate is often used to maintain osmotic balance and reduce cellular edema.
How does hypothermia enhance the effectiveness of preservation solutions?
A) It increases metabolic rates.
B) It dilutes the solution.
