Final answer:
Each person must be examined by a physician within 72 hours of entering a receiving facility to assess their ability to provide express and informed consent to treatment.
Step-by-step explanation:
As soon as possible, but no longer than 72 hours from entering a designated receiving facility on a voluntary or involuntary basis, each person shall be examined by the admitting physician to assess the person's ability to provide express and informed consent to admission and treatment. This timeframe is crucial to ensure the rights and safety of the individual being admitted. Informed consent is a critical aspect of healthcare and research ethics, ensuring that individuals understand the nature of the treatment or experiment they are agreeing to, and acknowledging that they are participating voluntarily and without coercion.
