The nurse anticipates which antibiotic class, due to the lack of ototoxicity, will be ordered for a patient diagnosed with tympanic membrane rupture?
Penicillin
Aminoglycoside
Fluoroquinolone
Cephalosporin
The Correct Answer is C

D. Cephalosporins are not typically ototoxic but are less commonly used for tympanic membrane ruptures compared to fluoroquinolones.
