Show Suggested Answer Hide Answer
Suggested Answer: C

We have 1g of potassium permanganate in 25mL We have 300mL of solution

For every 25mL of that 300mL, we have 1g of KmnO4

300mL must have 12g of potassium permanganate (300ml/25mL)

Wow, this guy's got more meds than a walking pharmacy! I wonder if he's going to start glowing in the dark or something. *chuckles* Anyway, let's get down to business and figure out that creatinine clearance.

Woah, this guy is really medicated! Dexamethasone, Ondansetron, Levothyroxine, Lisinopril, Citalopram, and a whole bunch of other stuff. I hope he's not growing a third arm or something!

Hmm, let's see, 5'4\' and 85 kg... Looks like we need to use the Cockcroft-Gault equation to calculate the creatinine clearance based on the ideal body weight. Let's get calculating!
