 So let's talk about Merth's baby. Let's talk about two plus three Yeah So I've had a few questions all about the recent drugs calculations exam that I had I thought I'd just do a little vlog because there seems to be quite a few students that are really worrying and paddicking about the maths exams in Nursing and hopefully it's gonna reassure you and make you feel a little bit better about the situation Firstly, I'm gonna tell you now. I am terrible at maths. I'm not even joking I said in one of my other videos. I got an E for my GCSE in maths I am really bad and maths was one thing that I really really worried about when coming into nursing Especially second year because I knew it was gonna be drug calculations. I got myself in a frenzy I got myself in a panic. I'm sure I've logged about it and I was really really panicking about this But you know what? I've just sat my maths exam. It was drugs calculations and it was easy guys It was easy. I did it in seven minutes. We had ten questions It was we had 30 minutes to do it in I was finished in seven minutes That's how good it was because I was just there like what this is simple I didn't realize how simple it was so let me start you off with first year and also university entry because You're gonna some universities you have to sit a maths and English exam before you have your interview to get into nursing and these literally these exams are just basic and They are literally just multiplication their division their fractions their decimal points percentages There's nothing really awkward or tricky. No one's out to trip you up. They are really simple maths and It's literally if you go on to Google GCSE bite size or something and just have a go at those you'll be able to pass that so Let's erase that one first of all because it is just simple maths the first rule calculation question that I had was this one So I've just wrote it briefly and it's basically so the doctor prescribes Five milligrams of a lasso bean but the medication you have is 10 milligrams in two mils. How many millilitres will you need? Can you work it out? Basically, you've already got 10 milligrams in two mils. You only need five So it's literally half one mil. That's literally the answer It's as simple as that but if you have an equation like this, but there's different numbers and you really really can't work out because For whatever reason this is the equation you need So you need you need so what the doctor prescribes is what you need divided by what you've got in stock So whatever you've got in stock and then you times that by the stock volume So however many millilitres or whatever it's in So what you need divided by what you've got times by stock volume and that's literally the only equation you need for that part and It will save your life if you come to a trickier sort of question, but that question for me was quite an easy one and They're not out to trick you. So why would they trick you that you know? They just want to know your skills and that you can work something out because we need nurses Why they want to trick you the next one is about Percentage of body weight So if a patient loses weight, what percentage of their body weight have they lost and I was just like what how do you work this out? But it's so simple. I'm gonna explain it to you now Let's say you have a patient that is 69 kilograms that when they come on to your ward and when they go home They are 57 kilograms and you want to work out what percentage of the weight they have lost So when I show you the equation just stop the video and see if you can work out yourself And then I'll do the little explanation and show you how to work out and see if you got it right. Let me know So what you do is this equation So we'll ask divided by the original weight times a hundred and that will give you your percentage It will usually be point something something something in my experience. I haven't had a whole number yet. So Let's work this one out. So first you need what your actual weight loss is. You do the 69 kilograms Take away 57 kilograms, which will leave you 12 So then you do the 12 kilograms because that's the weight loss at the top and then you divide that by the original weight Which was the 69 and then you'll get a number like naught point one seven three Really long number times that by a hundred and you'll get 17 point three Something something something so now because it's a point number. You have to either round up or down Anything if you don't know how to do that anything so if you've got 17 point three So anything that's point four and below so point one point two point three point four below you round it down So that number will literally be seventeen percent and that's your answer because it's seventeen point three So you're rounding it down to seventeen so it's seventeen percent body loss and that's your answer but if it was to be 7.5 7.6 or 7.7 7.8 7.9 you round it up So then it'd be 18 percent. I hope that makes sense in my head. It makes sense when I'm explaining it makes sense I hope you understand that another question you might get is about IV fluids So the doctor prescribes a hundred milligrams of prednisolone in a thousand millilitres To be given over IV in 30 minutes, but how many millilitres? Per hour should the pump rate be set at so to me in my mind That's quite a simple question because you've already got the 30 minutes You've already got the millilitres that you need So you've got two 30 minutes in 60 minutes. So you literally just times in it by two. Does that make sense? So it's literally a thousand you've got your thousand and 30 minutes So then you double it because you want an hour and then that's it It's two thousand two thousand millilitres an hour. It's really really simple as that But then there is another one that might pop up. So you might have thousand milligrams in a thousand millilitres over 40 minutes But you want an hour and that's where it gets tricky and So what I would do is I would divide the thousand by 40 because then you're getting what it is per minute So 1,000 millilitres divided by 40 minutes that'll give you one minute So then you times that one one minute by 60 because you want 60 minutes over an hour Hope that makes sense. Let me just summarize that again So you've got your thousand millilitres, but it's only in 40 minutes So you want to divide your 1,000 millilitres by 40 because that's that'll give you the one It'll give you how many millilitres per minute then so a thousand millilitres divided by 40 is 25 And then you times that by 60 because you've got the 25 millilitres But that's just for one minute So then you times it by 60 because you want it in an hour and you get 1,500 and that'll be your answer I hope that makes sense and I really hope that I'm explaining it properly. It's not too bad I know it probably sounds worse than it is and then you've probably googled and you probably think oh my god It's not that bad and for ours. We've got a calculator. So it was really easy And fingers crossed for you all if you've got any questions, please ask me and If I can explain anything a bit more let me know I'm going to find some links and I'll put some links below as well. So Yeah, I hope that helps and I hope that reassures you And I hope that you feel a little bit better about the maths calculations because I don't want it to put anyone off Going into uni or Being so scared. I know it's nerve-wrecking doing exams anyway because I was really nervous for mine And before I did my drugs calculations. I was I was terrified But now I've done it. I'm just like actually that was wasn't too bad As long as you read the question and understand the question and use the equations You're gonna be all right. Honestly, you're gonna be fine. It's not that bad. I'm terrible at maths And if I can do it you can do it
