The Provider Has Ordered Amoxicillin with Clavulanate (Augmentin) for a Child

The provider has ordered amoxicillin with clavulanate (Augmentin) for a child who has otitis media. The child's parent asks why this drug is necessary when amoxicillin is less expensive. The nurse will explain that clavulanate is added to amoxicillin because it:

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.
