Def not a math major (BS/PharmD), but your explanation was like seeing through a visual illusion for the first time! lol
I was always taught PEMDAS growing up, and that the MD and the AS was read left to right in an equation like above. But stating the division as a fraction completely changes my mind now about how this calculation works. I think what would happen in a calculation I use every day if the former was used.
Example: Cockcroft-Gault Equation (estimation of renal function)
(140-age)(kg) / 72(SCr) vs (140-age) X kg ➗72 X SCr
In the first eq (correct one) an 80yo patient who weighs 65kg and has an SCr ~ 1.5 = 36.11
In the latter it = 81.25 (waaay too high for an 80yo lol)
edit: calculation variable
Auditory hallucinations are most common. The sounds of flies buzzing around your head non-stop, creatures climbing up the walls/ceilings
Also, fun fact, there is a couple mnemonica for anticholinergic poisoning and they go:
red as a beet, dry as a bone, blind as a bat, mad as a hatter, hot as a hare, and full as a flask
But in pharmacy school we mostly said:
“No See, No Pee, No Spit, No Shit”
