CTP Organ Preservation Techniques

Question 1

What is the primary goal of organ preservation?

Accepted Answer

To maintain organ viability until transplantation.

Answer

To improve the donor's health.

Answer

To prevent organ rejection by the recipient.

Answer

To reduce the need for immunosuppressive drugs.

Question 2

Which of the following techniques is commonly used for organ preservation?

Accepted Answer

Hypothermic storage to slow down metabolic processes.

Answer

Rewarming the organ to body temperature.

Answer

Freezing the organ to preserve it.

Answer

Storing the organ at room temperature.

Question 3

Why is cold ischemic time important in organ preservation?

Accepted Answer

Longer cold ischemic times can damage the organ and reduce transplant success.

Answer

It increases the success rate of transplantation.

Answer

It shortens the time required for organ recovery.

Answer

It improves organ function after transplantation.

Question 4

What is one of the main challenges in organ preservation?

Accepted Answer

Preventing ischemic damage during preservation.

Answer

Maintaining blood pressure during storage.

Answer

Increasing blood circulation to the organ.

Answer

Ensuring that the organ remains at body temperature.

Question 5

Which solution is typically used for organ preservation?

Accepted Answer

University of Wisconsin (UW) solution.

Answer

Normal saline solution.

Answer

Sterile water.

Answer

Dextrose solution.

Question 6

Why is it important to minimize organ exposure to air during preservation?

Accepted Answer

It prevents cellular damage by limiting oxidative stress.

Answer

It helps the organ absorb nutrients.

Answer

It makes the organ easier to transport.

Answer

It improves the color of the organ.

Question 7

What is shaping in organ preservation techniques?

Accepted Answer

Shaping reinforces successive approximations of a behavior.

Answer

Shaping is used to punish undesirable behaviors.

Answer

Shaping eliminates the need for rewards.

Answer

Shaping only works with verbal behaviors.

Question 8

What is the impact of organ preservation time on transplantation success?

Accepted Answer

Shorter preservation times result in better organ function.

Answer

Longer preservation times improve transplant outcomes.

Answer

Longer preservation times cause no change in function.

Answer

Longer preservation times guarantee better success.

Question 9

Why is monitoring temperature during organ preservation critical?

Accepted Answer

It helps maintain low metabolic activity and prevents organ damage.

Answer

It speeds up the preservation process.

Answer

It prevents bacterial growth.

Answer

It increases the viability of the organ.
