Question 9' [1 point} A drug is administered estersr 4 hours in dose of 10 mg. The dnJg is neutralized at an exponential rate with dEEa'f rate constant l: = (1.1. Not all the drug is neutralized before the next dose is administered. Let - Alt]: denote the amount of drug in the patient's system at time t hours, - E3\": denote the amount of drug in the patient at the beginning of the n+1 dosage interval, and - Fin: denote the residual amount of the drug left in the pa tent at the end of the nth dosage interval. Note.- The general form of the Exponential decay Model is Mt) = Ame\"i where: . AD: denote the initial amount presented at time t = El. - to denote the decay; rate (unit: 1ftime} .
