Maintaining a certification to work in a healthcare facility is considered a regulation because regulations are formal rules established by official bodies to ensure that professionals meet specific standards necessary for safe and effective practice. In healthcare, regulations often stem from governmental or regulatory agencies and are intended to protect public health and ensure that practitioners are qualified to provide care.

Certificates and licenses are typically required to demonstrate competency and adherence to professional standards, and failing to maintain these qualifications can result in legal repercussions or the inability to practice within that facility. This highlights the importance of regulations in safeguarding patient safety and promoting high standards of care within the healthcare system.

The other options like rules, guidelines, and instructions may provide frameworks or recommendations for behavior and practice, but they lack the enforceable authority that regulations possess, thus making certification maintenance a regulatory requirement.
