Final answer:
The completed authorization form in a veterinary practice for legal agreement on actions to be taken is the consent form. Additionally, the informed consent form is essential for participants in experiments, detailing research expectations and ensuring confidentiality and voluntariness.
Step-by-step explanation:
The completed authorization form that provides the veterinary practice with legal evidence that the owner has been informed of important information and has agreed to pursue a certain action is the consent form. Similarly, before participating in an experiment, individuals should read and sign the informed consent form. This form provides a written description of what participants can expect during the experiment, including potential risks and implications of the research. It also informs participants that their involvement is voluntary and can be discontinued at any time without penalty. For minors, the parents or legal guardians are required to sign the informed consent form.
