If an antibiotic is taken orally, only a fraction of the antibiotic is actually absorbed in the bloodstream. This fraction is called bioavailability of the dose. Suppose that for a specific antibiotic, when :5 mg is taken orally, only 70% of the dose is absorbed, that is 7 the bioavailability can be expressed as :c. 10 Now, if 17. mg of antibiotic enters the bloodstream, the amount eventually absorbed at the site of the infection is 902) = h5f5 mg. Finally, if 9 mg is absorbed into the site of the infection, the number of surviving bacteria is given by 3400 f(g) 9+9, CFU (colony forming units). a) If a dose of 6 mg is given orally, compute the amount of antibiotic absorbed at the site of infection. Answer: :] mg. Round to 1 decimal place as needed. b) If an amount of 7 mg enters the bloodstream, compute the amount that is eventaully absorbed at the site of the infection. Answer: :] mg. Round to 1 decimal place as needed. c) If a dose of 5 mg is injected directly into the bloodstream compute the number of surviving bacteria . Answer: :. Round to the nearest whole number
