Choice C is wrong because tetracycline can cause hepatic impairment only in patients with preexisting liver disease or who take high doses for a long time.

Correct Answer is E

Explanation

Gentamicin is an example of a concentration-dependent antimicrobial, which means that it achieves increasing bacterial kill with increasing levels of drug.The peak concentration and the area under the concentration curve (AUC) determine the efficacy of these antibiotics.Other examples of concentration-dependent antimicrobials include fluoroquinolones, daptomycin, aminoglycosides, and amphotericin

Choice A is wrong because ciprofloxacin is a fluoroquinolone, which is also a concentration-dependent antimicrobial.

Choice B is wrong because imipenem is a carbapenem, which is a type of beta-lactam antibiotic.Beta-lactams are time-dependent antimicrobials, which means that their bactericidal activity depends on the duration of the effective concentration.

Choice C is wrong because penicillin V is another type of beta-lactam antibiotic, which is also a time-dependent antimicrobial.

Choice D is wrong because metronidazole is a bactericidal agent that has both time- and concentration-dependent properties.However, it is not classified as a concentration-dependent antimicrobial according to the AMEG categorization of antibiotics in the European Union.

A. Red-orange discoloration of body fluids B. Metallic taste in mouth C. Photosensitivity reaction D. Ototoxicity.

Correct Answer is A

Explanation

The nurse should instruct the client about this possibility and reassure them that it is harmless and will disappear when the medication is discontinued.

Choice B is wrong because metallic taste in mouth is not a side effect of rifampin, but of metronidazole, an antibiotic used to treat infections caused by anaerobic bacteria or protozoa.

Choice C is wrong because photosensitivity reaction is not a side effect of rifampin, but of tetracycline, an antibiotic used to treat acne and other infections.

Choice D is wrong because ototoxicity is not a side effect of rifampin, but of aminoglycosides, a class of antibiotics used to treat serious infections caused by gram-negative bacteria.

Ototoxicity can cause hearing loss or balance problems.
