Final answer:
Intentionally ending the life of a terminally ill person through an overdose of medication is called Euthanasia, and it can be either passive or active, including voluntary and nonvoluntary forms.
Step-by-step explanation:
Intentionally ending the life of a terminally ill person, through an overdose of medication, is called A) Euthanasia. Euthanasia can be both passive, where treatment is withheld leading to death, or active, which involves interventions such as administering a lethal dose of medication. It is crucial to note that euthanasia can be voluntary, at the patient's request, or nonvoluntary, where the patient is incapable of making the decision.
Euthanasia is distinct from options such as B) Palliative care, C) Hospice care, which seek to provide comfort without hastening death, or D) Advance directive, which allows a person to instruct beforehand if they want life-sustaining measures withheld. Medication in the context of active euthanasia is used purposefully to end a life, whereas in palliative care, it is used to manage symptoms.
