Final answer:
When a patient is mentally or psychologically compromised, a substitute decision-maker or advocate should be involved in the decision-making process. This ensures the patient's best interests are considered.
Step-by-step explanation:
When a patient is mentally or psychologically compromised or experiencing a severe physical illness that impairs their judgment, it is important to involve a substitute decision-maker or advocate in the decision-making process. This can be a family member, a legal guardian, or a healthcare proxy who can make decisions on behalf of the patient and ensure their best interests are considered.
By involving a substitute decision-maker or advocate, healthcare providers can uphold the principle of autonomy and ensure that decisions align with the patient's values and preferences, even if they cannot provide informed consent themselves. It is crucial to respect the rights and dignity of the patient while making decisions in their best interest.
