Answer to Question 1

ANS: A
The primary route for drug elimination is the renal system. If kidney function is impaired, drugs may reach toxic levels.

Answer to Question 2

ANS: B
Bioavailability is the percentage of the administered drug dose that reaches the systemic circulation. Oral drugs that have a high first-pass hepatic metabolism may have a bioavailability of only 20 to 40 on entering systemic circulation. To obtain the desired drug effect, the oral dose could be three to five times larger than the drug dose for IV use.
