The EMT shows he understands Do Not Resuscitate (DNR) orders and a living will when he states:

A) "A living will is a form of DNR; only a living will states exactly how the patient wants to be resuscitated."
B) "A DNR applies to resuscitation issues only, like when a patient stops breathing or the heart ceases to beat."
C) "If a patient has a valid DNR, the EMT should withhold all care and transport the patient to the hospital."
D) "If the patient has a living will, it can legally be used as a substitute for a Do Not Resuscitate order."
