Answer to Question 1

B
Feedback:
Ototoxicity (auditory or vestibular) may develop after extended use of gentamicin and may not be reversible. Penicillin allergies and immunocompromised status are not risk factors for ototoxicity.

Answer to Question 2

A
Feedback:
In general, people heavier than average may need larger doses, provided their renal, hepatic, and cardiovascular functions are adequate.
