  1. A 62-year old male patient with liver disease asks you why he is receiving a drug intravenously rather than by mouth. What is your best response?
    1. “Many oral drugs are inactivated as you get older.”

    3. “Intravenous drugs reduce toxicity to the liver through first-pass metabolism.”
    4. “Individuals with liver disease have a genetic impairment that prevents drug activation.”



  1. A patient who is beginning a new cholesterol-lowering drug tells you he plans to take this drug in the evening with his usual glass of grapefruit juice. What is your best response?
    1. “The vitamin C in grapefruit juice enhances the action of cholesterol-lowering drugs.”
    2. “The acid environment of grapefruit juice promotes drug metabolism.”
    3. “Taking grapefruit juice can reduce the effectiveness of the drug.”
    4. “Taking grapefruit juice can increase the absorption of the drug.”



  1. You give a patient 400 mg of an oral drug at noon. This drug has a half-life of 2 h. At what time will 100 mg remain?


a.   2:00 p.m.

b.   6:00 p.m.

c.   8:00 p.m.

d.   4:00 p.m.
