Final answer:
A patient refusing care and transportation after being informed about its necessity is said to be refusing medical advice (AMA). This is predicated on the ethical principle of autonomy in healthcare, which allows patients to make their own informed decisions.
Step-by-step explanation:
When a patient refuses care and transportation, even though a healthcare professional has communicated to them that it is necessary, the patient is refusing medical advice (AMA). This is a situation where the principle of autonomy is exercised, as patients have the right to make their own healthcare decisions, even if those decisions are contrary to the recommendations of their healthcare providers. Refusing treatment under these circumstances means that the patient has been informed about the risks and consequences of their decision and has decided to decline medical intervention despite this information.
The ethical considerations surrounding patient autonomy, such as the patient's right to decline medical interventions like hydration, nutrition, or decolonization procedures, further illustrate the importance of respecting a patient's decision. Additionally, the creation of living wills or advance directives (including DNR orders) is a manifestation of patients exercising their autonomy, ensuring their healthcare preferences are known and respected in case they can no longer communicate their wishes.
