For the second question, since we’re looking for ml/hr does that mean we’re looking for the infusion rate? The video has really helped understand the basics, thank you so much

Exactly, no guesses involved... This is such a waterproof method, which I actually use to help a nurse student with her calculations via video conferencing. Her teacher has given her extensive calculations which ofc make sense but are impossible to understand unless you learn everything by heart. So thanks for giving me a job, basically! Your method makes it so fun to teach :)

is there any way you can use this method to explain about drip sets and drops per minute? i’m having a hard time with prehospital dosages when they add drip sets like macros and micros…

@norlanmaltez7402 2 жыл бұрын

Glad you asked. Set up the problem the exact same way. Then plug in the drip set you are using as a conversion factor. e.g , micro drip tubing is 60 drops/mL. Make sure to flip this so that you can cancel the mL's, then you're left with drops/minute. For macro drip tubing, make sure you use the right one (i.e., 10 vs 15 vs 20 drop tubing).

A prescription for a suspension calls for a dose of 250mg to be given twice a day. If the suspension contains 300mg/5ml, how many ml are needed for one dose? Please solve this

@SynthesisMedEd 2 жыл бұрын

250mg is your given info. 300mg/5mL is your conversion factor. Flip it to 5mL/300mg and multiply this by 250mg. Now you can cancel out the mg's, and are left with mL's. (250 x 5) / 300 gives you your answer in mL's.

@k.a._135 2 жыл бұрын

@@amandas.6331 150mg is your given info. 125mg/4ml is the conversion. Turning 150 mg --> ?? ml Is your goal. So do like the video said: 150mg(info) x 125mg/4ml(conversion)= ?? ml *when you flip the conversion, you can get rid of the mg* 150mg x 4ml/125mg = ?? ml *mg in 150 & 125 cancel out once flipped which will lead to having only ml in the equation:* 150 x 4ml /125 = 4.8 ml Hope that helps

I thought you got to divide the 16 mL to two since it is Bid

@SynthesisMedEd 2 жыл бұрын

BID means give this dose twice per day. If the instructions say "## mg per day, divided q12hr" or "## mg per day, divided BID," then you divide the dose as per the instructions.

Where did you get the 5mL and 400mg at 4:16

@SynthesisMedEd 3 жыл бұрын

It is the drug concentration. This figure will be printed on the actual vial or infusion bag you are using. The drug concentration is a “conversion factor” that can be used in your math calculation. You can also flip the drug concentration (flip the numerator and denominator) as needed in order to cancel out the units you need to get rid of in your equation.

A prescription for a suspension dosage is 20mg/kg/day to be given every 8 hrs. If the suspension contains 250mg/5ml, how many ml are needed for a 3yr old boy with 13kilogram weight ? Please solve this

@sanyamjain9056 2 жыл бұрын

1.73 ml

@user-in2vx5ot4r 2 жыл бұрын

Per kg is to be given 20mg per day so to 13kg baby will given 13×20=260mg per day as baby weight is 13 kg. now the day is divided by every 8hr so it will become 3 times a day because 24hr÷8hr=3times. Now each time will be given 260mg/3times=86.66mg per time. Now 250mg/5ml dose is available so we can do the calculation as (5ml/250mg)×86.66=1.73ml per time

@humansloth4096 2 жыл бұрын

I think you are displaying the equation wrong such that it might confuse people, as it did me. The rate is 0.01 (mcg/kg)/min. So that would equate to 0.01 mcg/(kg)(min). This is what allows you to cancel minutes using dimensional analysis. The way your are displaying the equation makes it looks as though kg/min is in the denominator of the rate, which it is not. It is actually (kg)(min) which is in the denominator of the rate. Just a suggestion.
