@@itsclassicbants alright calm down he made a simple mistake. If you knew better you would have not needed his assistance... lol
dee dee think you’re an idiot for not getting the point
I love Med Math, I was so confused when I was in a Nursing school but I didn't give up. I taught myself for straight 2 weeks (my instructor was so confusing she wasn't helping at all) and since then it became my favorite. xoxo
Very helpful for those who are weak in math very simple to understand ok thanks Appreciated your support to pharmacy Technician community
Im so bad at maths. People have tried to help me figure it out but nothing has made me understand nursing maths like your videos! Thankyouuuuu
Thank you so much for making this. I don’t understand why nursing school teaches you how to do these calculations in the most complicated way. I was so frustrated and wasn’t getting anywhere.
It's designed to steal your money.
There is an error in the final answer to 2 litres over 8 hours. He did the math 40,000/480=83.33 not 250. You do the math
It shd be 83.3
Wipes forehead..I kept getting 83.3 which I round down to 83, but was wondering where he came up with 250!
Man, this is going to kill your patient.
yeah, should be 83
where's the 250 came from. 😂😂😂😂
anyway. Thanks a lot for this video. Helps me. Bigtime!!
Thank gawd! I suck at this anyway and this instructor literally is helping it click. Whew! I got 83 too!
Ah-ha! Here's the video i was looking for! Easy, quick, and it makes perfect sense! Thank you from pretty much every nursing student ever!
You're the best! I hate math!!! But your making things easier...the best "instructor" on UA-cam that's for sure!
I love this guy. Easy and clear. He just save me.
Thank you for this video great job. I’m studying for this PTCB. 🙏🏾
Thank you. Good job explaining everything I understand it. its okay that you are not an expert but you made it everything so clear. I am confident now when working out the math problems.
Thank you so much! You make it so simple. Everyone else complicates it!
Your formulas make it really easy to remember. Thank you!!!
thank you so much for making it so easy to understand. because of your tutorial am not scared of nursing pharmacology class. thanks again. you rock!!!!
Me too
brilliant videos def helped me understand how to lay the formulas out, before i watched the first video released tabs and ml i didnt have a clue and books werent helping, thank you so much
Everyone makes mistakes! He corrected it...despite that small error, I LOVE THIS GUY!
I'm very grateful to you for explaining this in a way that my simple brain can understand. Thank you.
thank you for making it so easy to understand. God bless you.
I can only learn from you! Your the best!!!!! Thank you more than you know!
Thanks for your videos on dosage calculations! They've helped me a lot ;-)
Thank you so far you are the only one that's helped me understand this!!!
Thank you so much for simple explanation.Its really helps.
Thanks for your help. These videos really help me...
Hi there! Thank you so much for your videos! They are the most helpful, least complicated, conscise, empowering nursing math videos I've come across. You have a very nice accent too and I was wondering if you could do a video on dehydrated patients based on the patient's weight, hydration deficit, maintainence fluids, and ongoing losses. I'm going into the Veterinary nursing field but our math problems are generally mostly the same or very similar. You're my favorite math instructor and thanks again! Keep up the great work!
Candy, if you get to round up a number look to see if it "goes up or comes down" EX: 83.3333 it goes down to 83. if it would be 83.5 it would be rounded to 84. every time you see 5 or higher it goes up, if it is below 5 it goes down.
(82.3= 82; 83.6= 84; 83.9=84; 83.452=83.5; 83.23=83) so look at the numbers that come after the decimal point if it is greater than 5 it will round up the number ahead of it 83.45= 83.5, or 83.455=83.5. I hope it helps you.
oh, you are a great teacher!!!
Love this formula is very easy
Well done
Thank you
Thankyou very much very well explained and easy to follow.
Thank you for making this easy.
You are the best thank you so much for such great explanation
Thank you for this!
you alone helped me pass pharm!!! thank you!!!
Great video!
Sir it’ is very well explain , thank you for your lecture . Well done👍
FINAL QUESTION IS 83.33... NOT 250!
Thank you x ❤️
o.m.g what a way i love itt please post more nursing calculation like drop/min
Thanks SO MUCH!!!
brilliant!
OMG..I FINALLY GET IT!!! LOL Thank you!!!!
thank you
Thank you so much.. I've learned your easiest way.. I totally understand it now..
I'm hoping if you could also post a video for insulin drug computation? It means a lot if you posted one..
Easier said, simple formula, thanks a lot.
Thanks
I've seen pretty much all of your nursing math videos. And I was wondering if you were going to do one on the safe rates for orders.
Here's an example: A Physician has ordered 200 U regular insulin in 500 ml NS to be given at 8 U/hr to an adult male who weighs 176lbs. The recommended adult IV dosage of regular insulin is 0.1 U/Kg/hr. Is the dosage safe?
I've been trying to work on stuff like this, like for this one I know that the order is 8 U/hr the supply is 200U/500ml, his weight is 80kg. I've got an issue getting the dimensional analysis in order for ones like this though. Do you think you can help?
Cheers.
11:20 should be 83 gtts/min not 250
I was doing it with my calculator and I was like wat the hell I'm getting 83 am I doing something wrong but I'm glad I'm not the only one who caught it cause I had to go back and look at wat I was doing wrong. So I was doing it right thanks. This guy is good though I understood it better
Oh I just read all the comment they said that already tehehe
i paused the video and i solved it then i continued watching comparing my answers to him but then i was like ha 250????????i solve again and again i used my cp and calculator and im still not convinced until i scroll down the comments below hehe
LMFAO!! I did my calculation like 5times thinking I was at wrong.. lol
You are forgiven. love your videos very helpful
I wish I found you before I graduated
I think, He mistakenly press the number in the calculator. 40,000/160=250. Or He multifly 8hr x 20 instead of 60dpm=160. But it was great, easy to remember.
Got a question. For the last question (1600ml over 8 hours) If you divide 1600 by 8 hours wouldn't that give you the ml/hr not the D.P.M.? Wouldn't you take the 200ml/hr and divide by 60min?
It's 83.3 not 250 but you are a good teacher... Thanks
Jovz Cagz I think the 250 was a deliberate curve ball to make sure we understood the concept
On 11:24 I keep getting 83.33 what exactly are the values you multiply and divide to get 250?
😍😍😍
Any math problems for reconstitution powder. The problems are confusing.
Thanks for your video. However, I tried many times to divide 40000/480 and I always get it equals 83.3 . Could you please check that? Thanks
Im confused on your problem with the 2 litres in 8 hours with a 20 drop set, we get to 40000 divided by 480 and you got 250 d.p.m? I got 83 d.p.m. Can you assist?
I have a question..
Earlier you said when calculating drip rates, to always round up. Yet during the corrected question with the answer 83, I calculated 83.3 - should it be rounded up to 84? or is it still general rounding up and down rules??
of course you need to round it up, because you cant measure 0.3 of a drop, therefore you will round it to 83 drops, because its 83.3 if it was 83,5 or 83, 6 then you would round it to the next whole number.
Technically that's rounding down.
I was trying to clarify what was meant by "round up" - whether it be round up to the nearest whole number or rounded in general up/down method.
It is ground into me from my casual job to round UP no matter what the price. eg: $12.91 has to round UP to $12.95.. goes against all math laws, but that's just one way discount companies catch their customers.
So I felt I needed to ensure the term "round up" did or did not mean literally 'up'.
Tx
83.3 round down to 83
You always round up for drips. Should be 84 otherwise meds/fluid is left in the bag
can you help me with this math problem 425 grams of sucrose is added to 500ml of water with resulting volume of 850ml. express the concentration of sucrose as w/w and w/v product
divide 850 by 425=0.5, meaning there 0.5grams of sucrose in each ml of product, sucrose is 50%
Zi think the 250 answer was a deliberate curve ball to make sure we understood the concept.
help need some help with this calculation: 20,000 units of heparin is added to 500ml of .9% normal saline. Dose prescribed is 200 units per hour. Calculate the rate of infusion in ml/hr
@11:19 when I calculated I got 83.3333 which would be 84 by rounding but your answer was 250dpm. Can u tell me what I did wrong please?
Nothing he is wrong. I did it multiple times. The computer calculator does not lie haha.
The physicans orders cefarzolin 1 gram to infuse over 30 mins. The label on the cefarzolin bag indicates the volume is 50ml and the drop factor is 10dropd/ml. The nurse sets the I've to infuse at how many drops per minute? Please help me with this
I got 17 drops per minute. 10gtt/1mL x 50mL/30 min = 16.7 gtt/mL rounded up to 17. Here, 1 gram cefarzolin is constituted inside the 50mL, and so that may confuse others as to where we would put 1 gram in the equation, but it is not necessary at all.
Yep, take a look at my comment.
I also got 83.33. what happend is in this video the man didn't make the fractions smaller and thats why everyones confused.. It is in fact 83 drops per minute.
Can anyone please direct me to the video that explains how he cancels down the fractions into numbers? I understand all the formulas but I'm really struggling with getting my fractions down into the correct numbers
JHS Khan Academy, they are brilliant.
sir the answer is 83.33 not 250
Jerlyn Tumpang yeah cuz I was like WTF lol but he's still extremely helpful I love these videos
***** mines was too lol
Please calculate: IV Drip dose/min 0.1 GRAM OF ARAMINE IN 500 CC OF d5w HAS BEEN ORDERED FOR iv infusion @ a rate of 0.4 mg/min. How many microdrops pe min should you infuse with an administration set that delivers 60 gtts/cc
Dimensional analysis: 60gtt/mL x 500mL/100mg x 0.4mg/min = 12,000/100 = 120 gtt/min.
9:15 where is the 60 from I know it’s mins in an hr but how did he get it
Got it now
the last answer was 1600mls/8hrs(480mins)=3gtts/min
no, the answer is 200. If the cancelling out confuses you, just go ahead and multiply it out.
Thanks for your information
but 40000 dived by 480 =83,3
the last one that ask for the drop rate,usually thats ml/hr shouldnt the answer be given in ml/hr nd if its d.p.m why didnt u convert the 8hrs to minutes.
why dont you reduce the fractions?
I was confused in D. P.R my answer is 83.3.
yes I agree...my answer is also 83gtts/min
Yes he's wrong
Nania haje abbas me too
Yes a booboo in DPR.
Answer is 83.3
Oo bobo nyan haha pang micro drip 250na sagot nya..
insulin pump has been set up at 4mls/hour. the concentration of the pump is 50 units in 50 mls.what is the prescribed rate in units of insulin/hour?
Pls answer it
What is an easy formula if you do not have the numbers of hours given in the problem? Example: "Lidocaine IV drip 2 grams/250 ml to infuse at 4mg/minute. How many ml/hr should be administered?" I know that we will have to convert grams to mg,therefore this will turn into 2000mg. Thanks!!
ArabSicily 2 grams/250 ml to infuse at 4mg/minute. This equals 2000mg/250ml as you have said.4mg per minute means 240mg per hour (4mg x 60)So if 2000mg : 250ml 240mg : ___ml2000 / 240 =8.333250 / 8.333 = 30ml required.or, This is a Stock Required (mg)/ Stock Supplied (mg) x volume (ml) = 240mg / 2000 mg x 250ml = 30ml
+ArabSicily desktop
Shouldn't we round to the nearest whole?
How is 40000/480 250?
For the IV calculations for question 5. You stated the answer is 250 drops per minute however that's incorrect it's actually 84 drops per minute.
yes good catch
+Julian Santos but you round to 83 not 84
You still have to round to the nearest whole number. The final answer is 83.
Error about the 40,000/480 my answer is 83.3dp I thought I was mistaken.. 🙄
cant u improve the audio quality
At least you graduated , now pray for the rest of us =)
I am sorry for the stupid questions but I am super confused in relation to which formula to refer my problem.Can someone walk me through and explain the example I am giving in here? you are asked to give 500 ml of lidocaine 0.2% infusion at a rate of 2 mg per minute .What is the infusion rate in ml/hour?
Sry but I don`t understand 6.1/2 hours =6.5 hours? can you explaine more? thx
1/2 = 0.5. so 6 1/2 is 6.5
40000÷480= 83.33 sir not 250
It’s 83 not 250 dpm 🤔
Shame he got one of the calcs wrong !!
I’ve watched a blank screen thru out the whole time 🙄👎🏻
