Textbook Question
Chapter 2.3, Problem 28ES
A drug administered to a patient produces a concentration in the bloodstream given by c(t) = Ate−t/3 milligrams per milliliter, t hours after A units have been injected. The maximum safe concentration is 1 mg/mL.
- a. What amount should be injected to reach this maximum safe concentration, and when does this maximum occur?
- b. An additional amount of this drug is to be administered to the patient after the concentration falls to 0.25 mg/mL. Determine, to the nearest minute, when this second injection should be given.
- c. Assume that the concentration from consecutive injections is additive and that 75% of the amount originally injected is administered in the second injection. When is it time for the third injection?
