The nurse practitioner is seeing a 56-year-old male client for the chief complaint of “a sore place on my bottom”. The physical examination reveals a painless, indurated ulcer on the client’s anus. No other skin lesions are noted. The client denies any recent illness. The NP orders a single dose of benzathine to be given intramuscularly. For which stage of syphilis is the client being treated?
