Final answer:
The statement is false as not all individuals involved in caring for clients need a professional license. Roles like nursing assistants and home health aides require training and certification, but not licensure.
Step-by-step explanation:
The statement 'All persons responsible for caring for a client must be a licensed professional' is False. Not all personnel involved in client care are required to have professional licenses. For example, personal care aides, nursing assistants, and home health aides are often responsible for client care but may not be licensed professionals. These roles typically require specific training and certification, but not professional licensure, which is usually reserved for roles such as registered nurses (RNs), licensed practical nurses (LPNs), physicians, and other healthcare providers.
