A patient that is suffering from dehydration, you're responsible for explaining dehydration.
00:09
Check all the answers that would tell the patient to treat treatment for life threatening symptoms of dehydration.
00:22
So first of all, let's look at look eight.
00:24
Drinking water will undo the stimulus of dehydration through a positive feedback loop.
00:30
This is incorrect.
00:31
Correct.
00:33
So while drinking water is able to restore the water, but it doesn't, it rehydrates the body, but it doesn't initiate a positive feedback loop to reverse dehydration.
00:47
It actually is a negative feedback because it's restored the balance.
00:53
So as you can see that the statement of, because you're losing water and ions so water rehydrates however it doesn't restore the balance through the positive feedback loop so the statement of positive feedback loop is wrong positive feedback loop basically means that if you have a change the system will reinforce this change to make it go even even further away from the original state.
01:39
But for dehydration, to correct the dehydration, you want to correct the dehydration.
01:47
So you want to restore the original state.
01:50
So it has to be a negative instead of positive.
01:55
So the negative feedback loop will restore the original balance, rehydrate the body, body can restore the original ion electrolyte concentration.
02:06
So it's not a positive feedback loop because it will give you more dehydration.
02:11
It's a negative feedback loop, which will restore the electrolyte concentration inside of the body.
02:17
So a is wrong.
02:19
B.
02:20
B says that dehydration disrupts the balance of fluid and electrolyte in the body, which is essential for keeping my factors the same inside a body b is the correct option it is in fact a there is a balance between fluid and electrolyte ions so this is extremely important um so when you want to rehydrate a person you want to give both fluid and electrolyte to make sure it's balanced um so so dehydration is actually a disruption of the balance of fluid and electrolyte.
03:06
So this is a correct statement.
03:10
C, intravenous fluid are administered to rapid correct fluid and electrolyte level, bringing the body back to a set point.
03:20
So this is also a correct statement.
03:23
This actually reflects the idea of what we just called the negative feedback loop...
