The nurse should identify that which of the following medications is contraindicated for this client?
Vancomycin.
Clarithromycin.
Metronidazole.
Ceftriaxone.
The Correct Answer is D
Ceftriaxone is contraindicated for this client because it is a cephalosporin antibiotic, which has a similar structure to penicillin and can cause cross-reactivity in individuals with a penicillin allergy.
Choice A is wrong because Vancomycin is not a beta-lactam antibiotic and does not have cross-reactivity with penicillin.
Choice B is wrong because Clarithromycin is a macrolide antibiotic and does not have cross-reactivity with penicillin.
Choice C is wrong because Metronidazole is a nitroimidazole antibiotic and does not have cross-reactivity with penicillin.
