Final answer:
Scopes of practice are determined by a combination of laws, regulations, and professional guidelines specific to each healthcare profession.
Step-by-step explanation:
'Scopes of practice' in the context of this question refers to the specific activities and procedures that healthcare professionals are legally allowed to perform within their profession. The sources that determine these scopes of practice vary depending on the profession and the country. In many cases, scopes of practice are based on professional guidelines and regulations set by governing bodies or organizations. For example, in the United States, the scope of practice for different healthcare professionals are determined by state laws and regulations, as well as professional organizations such as the American Medical Association or the American Nurses Association.
Therefore, the answer to the question is False. Scopes of practice are not based off of a single source, but rather on a combination of laws, regulations, and professional guidelines specific to each healthcare profession.
