Answer to Question 1

ANS: C
Peak levels should range from 4 to10 mcg/mL for traditional dosing and from 16 to 24 mcg/mL for once daily dosing. This value should be interpreted as subtherapeutic.
This value indicates subtherapeutic dosing and is not safe or toxic.
Peak levels are not irrelevant in medications that have significant risk for toxicity and have a narrow therapeutic index.

Answer to Question 2

ANS: B
Of the aminoglycosides, amikacin is the most resistant to bacteria.
The aminoglycosides pose no apparent risk of thrombophlebitis.
Amikacin is the preferred agent for initial treatment of infections caused by aerobic gram-negative bacilli, not gram-positive bacteria.
Amikacin is not eliminated any faster through the kidneys than the other aminoglycosides.
