Question

a healthcare provider prescribes cefadroxil for a client with a postoperative infection. it is most important for the nurse to assess for which additional drug allergy before administering this prescription?
penicillins.
aminoglycosides.
erythromycins.
sulfonamides.

Explanation:

Cefadroxil is a cephalosporin antibiotic. There is a significant cross - allergy between cephalosporins and penicillins due to similar chemical structures. So, before administering cefadroxil, it is most important to assess for penicillin allergy. Aminoglycosides, erythromycins, and sulfonamides do not have a significant cross - allergy with cephalosporins like penicillins do.

Answer:

A. Penicillins.
