Wouldn't be the example #4 675mg? 9.5 times 50mg = 475

[@ClaudiaMalone-yi1ww]

She doesn't show it on the slide, but if you use a calculator, the weight is 9.545454 kg. Multiply that number by 50 mg and that's how you get 477.27272. Round up the final number to 477 mg.

thanks for all the videos... so helpful....... i was confused with the last slide of video which says 1pound equals 2.2kg....... its actually opposite...

[@chrislovato3362]

Thanks to you, I know I'm going to ace the math section of the PTCB exam! Much appreciated.

Omg is so simple. Thanks Amanda

Thank you so much for your hard work

Thankyou for your videos!

[@sasisasi-ke2rg]

Very informative

[@JavierRodriguez-fr4in]

Nice video,your video is so cool. honestly PTCB is such a difficult test,really don’t know what to do but I’m not losing hope.

[@kateolivia717]

PTCB might seem so tough to pass but studying very hard is a very vital skill to win trust me

[@terrysimpson1531]

I’ve always believed PTCB is not all about studying, but you need God’s grace to pass .

[@jasoncoman8823]

@@terrysimpson1531 Yes you’re correct but remember heaven helps those who help themselves.if you can’t study then get yourself a good help.

[@deborahdebbie4953]

I have a cousin who never studied much, she gives most of her time to her phone than studies. after writing the PTCB test last month, she passed and I failed 😣. just found out she got her help from Mr Philip.

At times it doesn’t matter how hard you study you also need to pray to God for success..✍️

[@taihitiashelby1701]

Who is Mr kevin

[@ethanvargas8462]

on example #4a did you mean to put 475 and not 477 because i checked 3 different calculators and all 3 said that 50*9.5=475?

[@PRINCESS2U_]

I think she did because I'm like in my calculator it said a solid 475 I had to look in the comments to see if anyone else caught that!

[@sicktwinz9781]

I believe it’s because when you initially divide the weight (21lbs by 2.2kg) you get 9.5454545 and times that by 50mg you get 477 in total instead of 475.
Hope this helps.

[@JenniferFlores-dx1bz]

@@sicktwinz9781 so the question is, which one would be the right way? 😵‍💫

[@patsyprice6700]

Do you have a dido sheet that we can use to practice these kind of problems ❤

[@jadmoqdad2834]

👍🏼

[@jerrylim2282]

I believe example #2 answer should be half of 670mg because frequency is q12h.

[@snotrajohnson]

The dose is stated as 10 mg/kg every 12 hours. In other words, that is the individual dose that’s given every 12 hours; no need to divide it.
If it said 10 mg/kg/d every 12 hours, then we’d divide the daily amount by the number of doses in a day.
Hope this helps anyone wondering about the same thing.

[@TheJunkiess69]

@@snotrajohnsonso if it’s 10mg q 12 h you dont divide but if it’s 10 mg q 12 h you do divide? explain please

[@snotrajohnson]

@@TheJunkiess69 If the dosage is stated as mg/kg every 12 hours, that is not the daily dose - it’s the dose each time it’s given to the patient, which in this case is every 12 hours.
10 mg/kg/d is the daily dosage in mg/kg. If giving the medicine every 12 hours, divide the stated daily dosage by 24h to get the hourly dosage then multiply by 12h to get the dose for every 12 hours.
So, for a 24 kg patient:
Basis = 10 mg/kg q12h
10 mg/kg x 24 kg = 240 mg
Dosage = 240 mg given every 12 hours (with a daily total of 240 mg/12h x 24 h = 480 mg)
vs:
Basis = 10 mg/kg/d q12h
10 mg/kg/d x 24 kg = 240 mg/d
240 mg/d x (1 d/24 h) = 10 mg/h x 12 h = 120 mg/12 h
Dosage = 120 mg given every 12 hours (with a daily total of 120 mg/12 h x 24 h = 240 mg)

Can you do more math videos they’re help me

[@sophiemegan2503]

Try Mr Philip.check my comment for more information

[@pianotnt]

So you don't multiply diagnolly just straight across and divide when caculation by weight

[@leonardsturrup7750]

1kg is equal to 2.2lbs. The written formula in this discussion should be corrected

[@musiquera3494]

Thank you for pointing out. I got confused for a while.

[@MisfitKatt]

1lb is 0.45kg est 2.2lb is 1kg sorry saw this was said after I typed

[@buttonzone]

First you said 1 lb = 2.2 kg. Then you said 1 kg=2.2 lbs. I don’t know which is correct and if I can trust your videos to teach me correctly.

[@rodneyh1947]

1kg = 2.2 lbs, just google it.
