"The most challenging patient I have had was when I worked in accident and emergency. A male patient was brought in under the influence of an unknown drug. He had been involved in an altercation, was stabbed multiple times, and bleeding profusely from his neck and abdomen. However, he had super-human strength from the drug he was on and fought the entire team. There were seven of us working on him, and we were having difficulty restraining him. Fortunately, I was able to inject him with a sedative so we could restrain him and address his wounds. When the tox report came back, it showed he had a large amount of PCP in his system, which is why he was so challenging to restrain and calm down."
