Certified Nursing Assistants (CNAs) and Licensed Nursing Assistants (LNAs)
Many caregivers hold certification as a CNA and/or LNA. In 2016, the Arizona Board of Nursing officially recognized CNAs and LNAs as separate roles, although the two positions remain very similar with only a few differences. To become certified through a state-approved program, applicants must be at least 16 years old and complete a minimum of 120 hours of classroom, laboratory, and clinical instruction. Many training programs also require background checks. After completing the program, candidates must pass a state competency exam to be placed on the registry as either a CNA or LNA. Individuals applying for CNA registry status receive certification once all requirements are fulfilled.
A major distinction between CNAs and LNAs involves the level of oversight provided by the Arizona Board of Nursing. Practice-related concerns involving CNAs fall under the authority of the Office of Inspector General (OIG), while issues involving LNAs are reviewed and resolved directly by the Board of Nursing. Because of this added oversight, LNA applicants must complete an additional application process and fingerprint background check. Renewal requirements also differ. CNAs must complete at least eight hours of work every two years to maintain certification, whereas LNAs are required to complete 160 hours within the same period to renew their licenses.
In practice, HHAs, LNAs, and CNAs share some responsibilities, including helping patients maintain a safe environment and assisting with personal care needs. However, LNAs and CNAs are also trained to perform basic nursing assistant duties. These responsibilities may include taking vital signs, recording height and weight, assisting with diagnostic procedures, applying clean dressings, and helping care for individuals with drains or tubes such as catheters or feeding tubes.
Under Arizona caregiver regulations, LNAs may administer medication in specific situations when delegated by a Licensed Practical Nurse (LPN) or Registered Nurse (RN), while CNAs are not permitted to do so. Additionally, all nursing or nursing-related services performed by or with the assistance of a CNA or LNA must be supervised by an LPN or RN.
