The nurse caring for a patient who will receive penicillin to treat an infection asks the patient about previous drug reactions. The patient reports having had a rash when taking amoxicillin (Amoxil). The nurse will contact the provider to
a. discuss giving a smaller dose of penicillin.
b. discuss using erythromycin (E-mycin) instead of penicillin.
c. request an order for diphenhydramine (Benadryl).
d. suggest that the patient receive cefuroxime (Ceftin).
ANS: B
Erythromycin is the drug of choice when penicillin is not an option. Giving smaller doses of penicillin does not prevent hypersensitivity reactions. Benadryl is useful when a hypersensitivity reaction has occurred. A small percentage of patients allergic to penicillins may be hypersensitive to cephalosporins.
