This document discusses medical/legal and ethical issues that EMTs may encounter, including scope of practice, advance directives like DNR orders, patient consent and refusal, and assessment and care at crime scenes. It defines an EMT's scope of practice and responsibilities. It explains that advance directives require written physician orders and that patients have the right to refuse resuscitation efforts or treatment, which EMTs must document thoroughly. It also notes that crime scenes require protecting evidence while providing medical care and being observant without interfering.
