MRCP2-2703

A 30-year-old man with a history of IV heroin use is brought to the Emergency Department with severe muscle spasms and abdominal pain. He reports difficulty finding clean needles and injection sites in recent weeks. On examination, there is an abscess in his right groin and he exhibits bilateral hyperreflexia and increased tone. When asked to swallow water, he begins to choke. Laboratory results show a low hemoglobin level, elevated white cell count and CRP, and abnormal liver function tests. What is the most suitable course of action at this point?
