Answer to Question 1

B
Feedback:
Cholestyramine should be administered 1 hour before or 4 to 6 hours after other medications, because it may prevent the absorption of other drugs. Therefore, the other options are incorrect.

Answer to Question 2

C
Feedback:
Microorganisms develop resistance in a number of ways, including the following: changing cellular permeability to prevent the drug from entering the cell or altering transport systems to exclude the drug from active transport into the cell; altering binding sites on the membranes or ribosomes, which then no longer accept the drug; and producing a chemical that acts as an antagonist to the drug. Microorganisms do not alter the blood supply to the infection, stop a cell from reproducing, or change the appearance of the cell membrane.
