Hello there i see we have a list of questions.
00:04
So the first one that we see is 150 milliliters of ns is to infuse at 225 milliliters per hour.
00:23
So it wants to calculate the infusion time in hours.
00:28
So how we're going to calculate this? so since i'm going to down to the infusion time that or the drip rate so our drip rate would be volume per millimeter over time or hour so how we go about this the soft sense we got the drip rate we would have to do drip rate times and now so basically it will be volume milliliters times our drip rate and this is how we get our time or our hour so since we see we got 25 and 150 milliliters we can just times that so then leaders so we see these get crossed out so we're left with time so 25 times 150 that will give us 3 ,000 750 hours i'm just right down here so you can see it so that's what the first one so a second question where patients, i mean, for, or fatenians, sorry, i budget, being infused at 25 million per hour and how the solution contains 10.
02:43
Let me scroll that down.
02:48
10 milligrams of penfinran in 250 milliliter solution.
03:03
They want to know how many m .g.
03:11
Per hour the patient is receiving.
03:14
So how we're going to go about calculating that? how we're going to go along with calculating this we'll go along with this by what we'll calculate so we might have so we got 10 m g and times that by 25 milliliters over our hour and we times that by 250 milliliters so what happens is that the mls, they cancel out.
04:04
So that's where we're only left with milligrams and hours.
04:09
So then we end up calculating this.
04:15
So it would be 10 times 25 times 25 and where we end up getting.
04:24
Oh wait, i did backwards for that to work.
04:28
We have to do this like over one.
04:32
So i'm basically, i'm defiding 250 over 25.
04:39
That's my bad.
04:44
So doing so, the actual answer would be 10 energy per hour.
04:56
So then the last question, the doctor, let me scroll this down.
05:00
The doctor odors, um, nitroglycerin at 500 mcg over minute.
05:13
The solution is 50mg of nitroglycerin and 250 milliliters.
05:27
And they want to calculate the flow rate.
05:30
Okay, so how are we going to calculate the flow rate? well, we're going to do a lot of conversions.
05:34
So the first one, we're going to converge the mc, i mean, micro milligrams to milligrams, which is we're basically got to divide.
05:47
Let me scroll down.
