A nurse is preparing to administer intramuscular penicillin to a patient who is infected with T. pallidum and notes that the order is for sodium penicillin G. Which action is correct?
a. Administer the drug as prescribed.
b. Contact the provider to discuss adminis-tering the drug intravenously.
c. Contact the provider to discuss changing the drug to benzathine penicillin G.
d. Request an order for piperacillin instead of penicillin G.
C
The procaine and benzathine penicillin salts are absorbed slowly and are considered repository preparations. When benzathine penicillin G is injected IM, penicillin G is absorbed for weeks and is useful only against highly sensitive organisms such as T. pallidum. Sodium penicillin G is absorbed rapidly, with peak effects in 15 minutes. Administering the drug IV will not yield repo-sitory effects. Piperacillin is not used for T. pallidum IC.
