  a. binds with albumin to increase the amount of available amoxicillin.
  b. broadens the spectrum of amoxicillin by inhibiting bacterial enzymes.
  c. inhibits hepatic blood flow, leading to increased serum drug levels of amoxicillin.
  d. inhibits the excretion of amoxicillin by interfering with renal function.

Answer to Question 1

ANS: B
Clavulanate is a bacterial enzyme inhibitor, specifically beta-lactamase, which inactivates amoxicillin. When added to amoxicillin, it broadens the antibacterial spectrum.

Answer to Question 2

ANS: A
Gut bacteria are necessary to hydrolyze estrogen conjugates into free estrogens. Concurrent antibiotic administration can alter these bacteria and prevent the optimal absorption and effectiveness of OCPs. A backup contraceptive method is recommended.
