You might’ve already seen this, but try using the method of dimensional analysis where you work backwards on a single line and you’ll never get one of those problems wrong again.
The key is just working backwards by units using the equations you have available. I know somebody that only got one of the questions on his MCAT correct bc he used this method lol.
I use dimensional analysis, but it’s over two lines… and not sure what you mean by working backwards, since the order doesn’t really matter so long as every value is in the correct line.
Since typing it out would be ugly as sin, example image stolen from google:
…they like to give us things like pt weight in lbs and oz, and ask for final product of tablespoons or some shit cuz they enjoy wasting our time, lol.
That the type you mean?
I know there are a few different ways to crunch the numbers, but DA is my favorite so far cuz it’s so consistent.
*edit, example pic changed, first one put mcg twice in the same line, which is a weird move. /shrug
99% of it is metric. I think the biggest outlier is home care, where you go visit some grandma who’s actively offended by metric, so if you tell her to take 7.5mL of something she’ll just do the deer in the headlights thing, then shove the bottle up her ass.
Tell her instead that she needs to take 3 Mountain Dew caps full and suddenly she can follow instructions enough to not kill herself.
I know it should be obvious and maybe I missed the sarcasm, but the teaspoon unit is in no way the same as an actual teaspoon utensil. I also don’t use my own feet to measure length.
I didn’t think that was sarcasm, it’s just such a jacked up system of measurement that he’s not confident it doesn’t change with borders, which is honestly a pretty reasonable point of uncertainty.
Until you start looking at old stuff and have you figure out if they were working with the “millions scheme” or “thousands scheme,” and if “1 billion” is equal to 1012 or 109
Gotcha! Yeah same page - some of the other students don’t like that method cuz it can take a bit longer, but building the equation kinda idiot proofs itself against calculating for the wrong unit, and it’s super consistent! Definitely my favorite so far.
Even dimensional analysis works best with metric because sometimes you need to convert units and almost all conversion in metric are base 10, so something like 1kg/km is 1000g/1000m is 1 gram per meter. But in imperial 1 pound/mile is 16 ounces / 5280 feet is who the fuck knows how many ounces per feet.

So USAnian drugs are in metric units? I hope in actual work nurses get to use a phone app or something because this asks for mistakes

Then she shoves the Mountain Dew bottle up her ass.
Yeah but that’s for pleasure.
“Doo the Dew!”
I thought everything is bigger across the ocean but your Mountain Dew caps are tiny over there! ;)
Just googled it and apparently they’re about 5mL each. Apparently I’m not great at eyeballing volume.
Add it to the pile of conversion failures between metric and imperial.
Yeah, 5ml is a teaspoon, but I’m not sure if it’s reasonable to assume teaspoons have similar sizes across countries.
But after your first month in the job you’ll convert and eyeball it even when half asleep :)

Even in the US, science is mostly metric. But most US people are not exactly the scientific kind…

That’s why you have methods of writing like 10x.
Modern science is, but there’s plenty of old journals from the 80s and earlier that use degrees Rankine and gallons.
Fucking BTUs and shit.
PSI is another one that seems to be used over the metric/SI alternative in some science-adjacent applications.
Hopefully you can read my chicken scratch lol
