Concept explainers
Drug infusion The delivery of a drug (such as an antibiotic) through an intravenous line may be modeled by the differential equation m′(t) + km(t) = I, where m(t) is the mass of the drug in the blood at time t ≥ 0, k is a constant that describes the rate at which the drug is absorbed, and I is the infusion rate.
a. Show by substitution that if the initial mass of drug in the blood is zero (m(0) = 0), then the solution of the initial value problem is
b. Graph the solution for I = 10 mg/hr and k = 0.05 hr–1.
c. Evaluate
