Final answer:
Generally, the statement is false; volunteering as a nurse still requires mandatory registration to ensure safe and effective care.
Step-by-step explanation:
The statement that individuals volunteering their nursing professional services are exempt from mandatory registration is generally false. Regulations regarding the practice of professional nursing, including the requirement for registration, typically apply whether the individual is being compensated or providing services on a volunteer basis. Volunteering does not negate the need for a nurse to be registered, as this ensures they are qualified and capable of providing safe and effective nursing care. Different regions might have specific laws or exceptions for certain volunteering situations, but as a rule, professional healthcare standards are not waived for volunteers to maintain the safety and quality of care.
