All right, let's try this one.
00:02
A physician orders 50 milliliters every 46 hours of tylenol 3 for a child who weighs 45 pounds.
00:09
The label states there is 12 milligrams of codeine per 5 milliliters and that the safe dosage is between 0 .5 and 1 milligram per kilogram per dose every 46 hours.
00:22
Is the physician's order suitable for this child? so to know if this is going to be safe for the child, we need to convert a couple of things.
00:30
First of all, this part here tells me what's safe and what's not safe.
00:34
So between 0 .5 and 1 milligram per kilogram per dose.
00:40
Notice that this is in terms of kilogram and our child is weighed in pounds.
00:46
So we've got to convert pounds to kilograms.
00:49
Pounds to kilograms.
00:55
Well, roughly 1 pound is right about 0 .45 kilograms.
01:02
Rounding up, 45.
01:07
It's like 453, but we're just going to say 45.
01:10
So that means that when i convert that 45 pounds, it'll be around 20 .4 kilograms.
01:22
All right, so we got what we need, 20 .4 kilograms...
