Drug Calcs made Easy: Simple Formula

[jhungahoy]

@SuperNicole0914

1 gr x 1,000 = 1,000 mg

1,000 mg / 200 mg x 1 = 5 tabs a day

formula: desired (1 gram)convert it to mg by multiplying it to 1,000 then divide it to available (200 mg) then multiply it to quantity ( 1 tablet)

your answer is 5 which means 5 tablet in morning and 5 tablet at night (twice a day)

Meth much?

[SuperNicole0914]

Could you please teach me how to solve this problem. A prescription specifies 1 gram of a drug to be taken twice a day. If a drug is available as 200 milligram tablets, how many tablets will the patient take per day?

[maribelmueller]

@SuperNicole0914

convert 1 g to mg= 1,000 mg

1,000 mg x 2/ day= 2,000mg

2,000mg/200mg= 10 tablets / day

What d u say??too fast..this is not easy way!

[kennaile]

[naturalchef2]

VCStoneBooks .......where is your video if you know so much? I would be interested in seeing that.

[sandalsalero]

You sound like Neil from Family Guy

[boybiboy21]

swift and deadly

[youbillyblake]

Gosh sake your words are running,

[TheSunngoddess]

Bloody Hell, Mister! Slow Down. :)

[leaderstube]

thank you so much for helping me to understand it in a way hundred time better than my teacher. keep it up

[MissCarmela007]

@MrChrisPaul75 Hiya!! Yes i passed.. I got 8 out of 10 which is a pass where i am :-) Thankyou very much for asking!!!

[VCStoneBooks]

Correction... How many g of the drug will be added to a 1L bag to achieve the proper dose?

[VCStoneBooks]

A Patient is to recieve 100 mg of a drug per hour in ana IV solution for a period of 24 hours. The total IV to be administered is 2 L. How many g of the drug must the patient recieve daily? How many g of the drug will be added to a 11 L bag , to achcieve the proper dose ? How many mL must the patient recieve per hr for the proper dose? What is the flow rate in mL/min? What is the flow rate in gtt/min (assuming the 15 gtt/ML admin set)?

[BIGLDH]

@VCStoneBooks Not overly difficult... Completely unrealistic set of questions... When do you ever NOT know your concentration? How often are you expected to calculate mL/min without first counting your drops/min? If you're an IV-Pump this is MAYBE... MAYBE plausible, but again, in the 'real world' you'd never be faced with this line of questions...However, here are your answers:

1) 1) 2.4grams total medication to be administered daily (24 hours x 100mg/hr)

*** answers continued..........

[BIGLDH]

@VCStoneBooks

2) I ASSUME you want the infusion split into two SEPARATE 1000mL bags as your total infusion is said to be 2 Liters... With that said, the answer SHOULD be 1200mg OR 1.2grams.

3 & 4) 54 mL/hr OR .9mL / min OR 13 gtts/min flow rate...

(Using 15gtts/min tubing, the pt. should receive 12.5gtts/min (rounded to 13gtts/min (unless you can accurately count a half-drip); [13gtts : x mL :: 15gtts : 1mL] = 0.87mL rounded to 0.9mL)

Again, NOT plausible, had fun with it!

kenllll

the problem was 700x27/2173=18900/2173=8.69765­3

which is rounded up to 8.70

[kenllll]

@JRAMOS0415 yup ur right i must of been high wen i calculated the dosage lol

[MissCarmela007]

I just failed my 2nd year nursing exam on drug calculations and am now revising for the re-take. I found your video to be incredibly helpful. You explain things clearly and with enthusiasm, great job! and Thankyou for taking the time to make this video :-)

[funlayo]

I find this interesting and easy.thanks.

[DeclanMBrennan]

i enjoyed your journey through the 'medication land'. I smile when I suggest maybe a little more time when writing the digits - finding it difficult to read the numbers. You have a great voice over. i like your approach to the subject. I do have to add that drug calculations need to be taken seriously in order to prevent drug errors

[kenllll]

700mlx27/2173 = 18700/2173 = 8.60 ml dunno where u got .70 from ?

[JRAMOS0415]

@kenllll

what he wrote was 700ml x 27/2173=18900/2173 that equals 8.697653

which is rounded up to 8.70

[kenllll]

@JRAMOS0415 ya i noticed dat but juz concerned , i'm not too sure ur suppose to round up medication e.g., heparin/insulin or other injections lol ? oral u might b able to since it might not make much of a difference from 8.69-8.70. i dun think it would make much of a difference what do u say ?

[JRAMOS0415]

@kenllll

I'm not entirely positive when it comes to insulin and heparin. In normal circumstances usually you can round up to the nearest hundreth. so if the number is 5 and up round up and if it's 4 or below you would round down. 8.69 would be 8.70 & 8.63 would be 8.60
