  1. Awesome ! Thanks Yuvi.
    I got all the questions right !
    for question 8) (Aminoglycoside) .. also hypokalemia and hypocalcemia can happen ! but possibly hypomagnesemia is the most common/characteristic.

  2. I agree, Hypomagnesemia is very characteristic for gentamycin toxicity. The toxicity also occus aftera few days of therapy! Great job with the questions. Hardly a few in the board review got all the questions right!
