- CGive the medication as ordered, as penicillins are in a different pharmacological class than cephalosporins.
- DAsk the client to sign a waiver acknowledging the potential risk of an allergic reaction prior to administration.
Cevap
Withhold the prescribed antibiotic and immediately inform the registered nurse or healthcare provider.
Penicillins and cephalosporins (such as cephalexin) both contain a beta-lactam ring in their chemical structure. Because of this similarity, clients with a severe or anaphylactic allergy to one have a well-documented risk of cross-sensitivity to the other. The safest and most appropriate action is to withhold the medication and notify the healthcare provider so a different class of antibiotic can be prescribed.
