Final answer:
The claim that mandatory registration is only for PNs in clinical practice is false; it applies to all practicing PNs, regardless of their role within the profession.
Step-by-step explanation:
The statement that mandatory registration requirements are only applicable to those Practical Nurses (PNs) in clinical practice is false. Mandatory registration requirements are in place for all practicing PNs, not just those in clinical practice but also those in non-clinical roles, such as education or research. Registration is a way to ensure that all PNs meet certain professional standards and can be held accountable for their practice, whether they are directly involved in patient care or contributing to the nursing profession in other ways.
