Answer to Question 1

D
Sulfonamides interact with several drugs and through metabolism-related interactions can inten-sify the effects of warfarin. Patients taking both should be monitored closely for bleeding ten-dencies. Changing to the combination product will not help, because sulfonamides are still present. Sulfonamides intensify glipizide levels, so this drug may actually need to be reduced. Trimethoprim, not sulfonamides, raises potassium levels.

Answer to Question 2

C
Clinical testing phase 2 involves patients, not normal volunteers, therefore further education is required.
Preclinical testing does take place in animals, therefore no further education is necessary.
Clinical testing phase 1 does involve normal volunteers, therefore no further education is needed.
Clinical testing phase 3 involves patients, therefore no further education is required.
