…being in nursing school is giving me a strong hatred for the imperial system.
The doctor ordered 35mg/kg Watdafuqenol IV QID. Available is a 2’ by 15" section of torn out carpet soaked in spilled Watdafuqenol; when wrung out into the patient’s left shoe, you get 97 chipmunk-mouthfuls diluted to a concentration of 24 Watdafuqenol to 1 toe jam. How many shot glasses full do you administer?
That’s a trick question. How many pound-feet of torque did you apply to the carpet?
1.15 pallets of spent 12-gauge casings over over the course of 2.3 standard breakfasts.
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
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.
You’ll never see dosage questions like that on the NCLEX. If you do it’ll be like one. I breezed through it when I took it, but basic knowledge questions are minimal (as long as you don’t get them wrong).
Metric is excellent until it gets into data units. There shouldn’t be a difference between 4T and 4TB, but it’s actually a (10244-10004) ≈ 92.6G (99.5GB) difference because of the fuckers who decided to make data units metric and rename the base-2 data units to “kibibyte”/“mibi*”/“gibi*” (KiB/MiB/GiB)
People weren’t using them ambiguously, drive manufactures picked a non-standard unit to lie with on their boxes, and then tricked courts into going along with their shit because it was the old case of money vs truth.
I think the biggest mistake there is using SI prefixes (such as kilo, mega, giga, tera) with bytes (or bits) to refer to the power of two near a power of ten in the first place. Had computer people had used other names for 1024 bytes and the like, this confusion between kibibytes and kilobytes could have been avoided. Computer people back then could have come up with a set of base·16 prefixes and used that for measuring data.
Maybe something like 65,536 bytes = 1,0000 (base 16) = 1 myri·byte; 4,294,967,296 bytes = 1,0000,0000 (base 16) = dyri·byte; and so on in groups of four hex digits instead of three decimal digits (16¹² = tryri·byte, 16¹⁶ = tesri·byte, etc). That’s just one system I pulled out of my ass (based on the myriad, and using Greek numbers to count groups of digits), and surely one can come up with a better system.
Anyways, while it’d take me a while to recognize one kilobyte as 1000 bytes and not as 1024 bytes, I think it’s better that ‘kilo’ always means 1000 times something in as many situations as possible.
Everybody knew exactly what kilo mega and giga ment. when drive vendors deliberatly lied on there pdf’s about their drive sizes. Warnings were issued: this drive will not work in a raid as a replacement for same size!!. And everybody was throwing fumes on mailinglists about the bullshit situation.
But money won, as usual.
Source: threw fumes!
There is no reason whatsoever to use base 16 for computer storage it is both unconnected to technology and common usage it is worse than either base 2 or 10
