This document discusses the concepts of informed consent and refusal of treatment. It outlines that patients have the right to refuse treatment as long as it is an informed refusal. For consent or refusal to be valid, the patient must be competent and the decision must be voluntary. The nurse's role is to ensure the patient understands the risks of refusing treatment through education. If refusal is documented, the record must show the teaching provided and that the patient understood risks but still refused.
