 You're working in the emergency department today. Your next patient is a 25-year-old male who's been brought in by police officers because of agitation. He has been pacing the room since he came in. You exit the room and ask the police officer for some collateral history. According to the police officer, the patient said he might have taken something earlier, but was unable to tell him what it was. You were seen behaving erratically in a public space and therefore the police officers were called. You then re-enter the room with the police officer present. You are unable to get a history. The patient states that he is very anxious. You suggest that the patient takes a medication to feel a bit more calm. You offer the patient some benzodiazepine, and the patient accepted. About 10-15 minutes later, the patient felt calmer and was able to lie down. You were able to do his vital signs. They included a temperature of 38, heart rate of 140, blood pressure of 150 over 95, breast rate of 20, and an otisaturation of 98%. The patient was able to give you a bit more history. He said that he has been using cocaine earlier. You then start your regular history in physical for this patient.
