Which of the following statements about the right to make health care decisions is true?

The statement that patients must be informed to make healthcare decisions is true because informed consent is a fundamental principle in medical ethics and patient rights. Patients have the right to receive comprehensive information about their diagnosis, treatment options, risks, benefits, and alternatives. This knowledge enables them to understand their choices fully and make decisions that align with their values and preferences. Without adequate information, patients cannot exercise their right to make informed and voluntary health care decisions.

In contrast, patients asking questions about their treatment is an essential part of the decision-making process, as it contributes to their understanding and informed consent. Physicians engaging in decision-making without patient input contravenes the principle of patient autonomy, where patients have the right to actively participate in their own care. Family members may offer support and insight, but they do not have the authority to override a patient's decisions about their own health care unless specifically designated by the patient, such as in instances of advance directives or power of attorney.
