Answer to Question 1

ANS: A
The selection of the antimicrobial agent must be based on the sensitivity of the pathogen and the possible toxicity to the patient. The half-life of the drug is not a concern with selection in comparison to sensitivity. Therapeutic levels of the drug are not criteria for selection. Bioavailability is a lesser concern than sensitivity.

Answer to Question 2

ANS: B
Eighth cranial nerve damage can result from aminoglycoside therapy. Patients should be monitored during therapy and after therapy has been discontinued for signs and symptoms of ototoxicity, including dizziness, tinnitus, and progressive hearing loss. Aminoglycosides do not produce bone marrow depression; this is characteristic of treatment with chloramphenicol. Aminoglycosides do not typically produce GI distress. Aminogylcosides do not produce photosensitivity; this is characteristic of treatment with glycylcyclines.

This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition.
