Okay this question says you have to match true or false for practically all of them.
00:05
It says for question number one the matching of abo blood groups is a first criteria when selecting a donor and the answer here is going to be true.
00:13
Okay the matching of abo blood groups is typically the first and most important criteria when selecting a donor for a blood transfusion.
00:20
This is because a mismatch between the donor and the recipient's blood type can result in a potentially life -threatening immune reaction in which the recipient's immune system attacks and destroys the donor's rbcs and well this is why this is true.
00:35
Then it says the reason this time impacts donor selection is due to the length of cold ischemia time and this option is also true.
00:45
Okay the cold ischemia time is a time that the donated organ or tissue remains outside the body at a reduced temperature between the time of removal from the donor and transplantation into the recipient.
00:59
During this time the organ or tissue can experience damage due to factors such as reduced blood flow, decreased oxygenation and inflammation.
01:07
The longer the cold ischemia time the greater the risk of damage and the lower the chances of a successful transplant.
01:14
For this reason organs and tissues are typically allocated to recipients based on proximity to minimize the cold ischemia time so this is why option two is also true.
01:25
The next question says recipients waiting for renal transplant don't get medical urgency priority because dialysis allows them a clinical management while on the wait list.
01:35
And this option here or this question here is going to be false.
01:39
Okay recipients waiting for renal transplants do receive medical urgency priority because dialysis is not a perfect replacement for a functioning kidney and the longer a person remains on dialysis the greater the risk of complications and mortality.
01:52
Dialysis remember that is a treatment that helps to replace some of the functions of the kidneys such as filtering waste products and excess fluid from the blood.
02:01
However dialysis is not as effective as a functioning kidney and patients on dialysis are at increased risk for a range of complications including infections, cardiovascular disease and other medical problems.
02:14
Okay for this reason patients with any stage viral disease who are on dialysis are typically given medical urgency priority when being considered for a kidney transplant and this means that the patients with the greatest medical need for a transplant are given priority over those who are less medically urgent...
