Final answer:

Step-by-step explanation:
The principle of autonomy in practice refers to the actions taken by a dental hygienist that respect the patient's right to make decisions about their own health care. One action that represents the principle of autonomy is facilitating patient health care decisions. This means that a dental hygienist should provide the patient with all the necessary information and support to make informed decisions about their oral health. For example, if a patient is given different treatment options for a dental issue, the hygienist should explain the pros and cons of each option and respect the patient's choice.
