Final answer:
A Registered Dental Hygienist in Alternative Practice (RDHAP) typically needs 25 Continuing Education Units (CEUs) every 2 years to maintain their licensure, although this requirement may vary by state.
Step-by-step explanation:
The number of Continuing Education Units (CEUs) a Registered Dental Hygienist in Alternative Practice (RDHAP) needs every 2 years is 25. In order to maintain their licensure, dental professionals are required to complete a specified number of CEUs within a renewal period. For RDHAPs, the requirement may vary depending on the state in which they are licensed; however, it is common for states to require around 25 CEUs for dental hygienists per renewal cycle. These CEUs ensure that dental professionals stay updated with the latest knowledge and practice standards in dental care.
