We have a prescription here of heparin.
00:07
Heparin is an anti -clotting factor and we're told that around 12 ,000 units are prescribed subcutaneously, right? but then the stock appeal we have, okay? stock ampute we have contained 25 ,000 units per 5 milliliters so what volume should be drawn up definitely first thing we need to understand is this if stock ampule is 25 000 units and volume of an ampule is one or rather a five um the volume of the ampule of the impule is 5 milliliters okay and then you're prescribing 12 ,000 units so you see 12 ,000 units is less than 25 ,000 units all right so it means the volume that will be drawn up will be less than okay so volume required will be less than uh 5 milliliters now can we calculate and see that can we good let's get to it the calculation will be it okay so so we are told we need to calculate the volume required.
01:34
Okay, so we're going to figure out how to go around this.
01:37
And to figure out the volume required, we need to, you know, calculate the strength required, okay? okay, okay.
01:58
Over what you call a stock strength, okay? and then we might play that by the volume, volume of stock solution.
02:18
Okay, you see that right? so the volume required, therefore, will be the strength required.
02:25
How much do we need from the question? we need 12 ,000, okay? we need 12 ,000 units...
