Which of the following is a requirement for ongoing licensure regarding continuing education for dental hygienists?

The requirement for ongoing licensure regarding continuing education for dental hygienists includes the necessity of maintaining a current CPR certification. This is vital because dental hygienists must be prepared to handle emergencies that could arise during procedures, ensuring patient safety is paramount. Having an up-to-date CPR certification reflects a commitment to ongoing professional development and readiness to respond effectively to medical emergencies, which is a key aspect of practicing safely and ethically in the dental field.

While the other options may seem beneficial for a dental hygienist's practice or career, they do not align with the specific continuing education requirements set forth for licensure. Maintaining a current CPR card ensures that dental hygienists have the necessary skills to act in emergencies and comply with the standards expected in dental hygiene practice.
