A patient has an infection caused by Streptococcus pyogenes. The prescriber has ordered dicloxacillin PO. What will the nurse do?
a. Administer the medication as ordered.
b. Contact the provider to suggest giving the drug IV.
c. Question the need for a penicillinase-resistant penicillin.
d. Suggest ordering vancomycin to treat this infection.
ANS: C
Penicillinase-resistant penicillins have been developed for use against penicillinase-producing strains of staphylococci. These drugs have a very narrow antimicrobial spectrum and should be used only for such infections. S. pyogenes can be treated with penicillin G. The nurse should question the order. It is incorrect to contact the provider to ask for IV dosing. This infection can be treated with penicillin G and not with vancomycin.
