Informed consent is a key ethical and legal requirement in healthcare and research to maintain patient autonomy.
Step-by-step explanation:
A patient who voluntarily allows touching, examination, and/or treatment by a healthcare worker has provided D. Informed consent. This concept is critical in the healthcare industry, as it is closely related to the principle of autonomy, which dictates that patients have the right to make informed decisions about their medical care. Informed consent is not simply permission; it encompasses understanding the full scope of the treatment, including its risks and benefits, and agreeing to the course of action based on that knowledge.
It is a fundamental ethical and legal requirement in all medical practices and clinical studies to ensure patient autonomy and to protect individuals from exploitation or harm. In the case of research or clinical trials, prior to participation, individuals are required to read and sign an informed consent form which provides all necessary information regarding the study. The informed consent form is a means to ensure that the participant is making an informed and voluntary decision regarding their involvement in the trial or treatment.
