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
A. Penicillins are generally safe but are not specific for ototoxicity considerations.
B. Aminoglycosides are avoided in cases of tympanic membrane rupture due to their ototoxic potential, which can lead to hearing loss.
C. Fluoroquinolones, particularly those formulated for otic use, are preferred for tympanic membrane ruptures as they are not ototoxic and are safe for middle ear exposure.
D. Cephalosporins are not typically ototoxic but are less commonly used for tympanic membrane ruptures compared to fluoroquinolones.

C. Increasing intake of green vegetables is generally healthy but does not directly impact lisinopril's effects.
D. Many salt substitutes contain potassium, which could elevate potassium levels further when taken with ACE inhibitors like lisinopril, posing a risk for hyperkalemia.
