Which principle states a patient must have sufficient information and understanding before making medical decisions?

• A. Autonomy
• B. Informed consent
• C. Cultural competence
• D. Social determinants of health

Answer: (B)

Informed consent is the process that ensures a patient has enough information and understanding before agreeing to medical care. It is how we translate respect for patient autonomy into real action, by providing clear details about what a procedure involves, its risks and benefits, and available alternatives, and then confirming the patient truly understands and agrees voluntarily. Without this understanding, a decision cannot be considered truly informed.

Understanding autonomy helps explain why informed consent is essential: autonomy is about the patient’s right to decide what happens to their body, and informed consent is the practical mechanism that makes that right meaningful in real clinical scenarios. The other terms describe related ideas but not the prerequisite for decision making: cultural competence focuses on communicating effectively across diverse backgrounds, and social determinants of health refer to the broader conditions that influence health outcomes.
