RN, LPN, CNA, or Caregiver: Who Is Coming to the House, and What Each One Can Legally Do in Arizona

Arizona regulates these roles through licensure, not job titles alone. The Arizona State Board of Nursing licenses registered nurses and practical nurses (LPNs), and it sets and enforces the scope of practice each one may perform. A certified nursing assistant completes a state-approved training program and is listed on the Arizona Nurse Aide Registry, which is a certification rather than a full nursing license. A caregiver, sometimes called a home care aide or personal care attendant, typically holds no state nursing license or certification at all. The title someone uses on a business card matters less than which of these four categories, RN, LPN, CNA, or caregiver, they actually fall into, because that category is what the law says they are allowed to do once they're inside your home.

A caregiver's role in Arizona centers on activities of daily living rather than clinical tasks. That typically includes bathing, dressing, grooming, meal preparation, light housekeeping, transportation to appointments, and companionship. A caregiver can also remind a client that it's time to take a medication and hand over a pre-filled pillbox, but reminding someone is not the same as administering a dose. Caregivers who work through a licensed home care agency in Arizona usually complete agency-specific training and a background check, often including a Level I fingerprint clearance card, but none of that authorizes clinical patient care. The moment a task requires assessing a symptom, touching a wound, or handling medication beyond a simple reminder, it has moved outside a caregiver's legal scope.

A certified nursing assistant works under the supervision of a registered nurse or licensed practical nurse and is trained to perform tasks a caregiver legally cannot. A CNA can take and record vital signs (temperature, pulse, respiration, and blood pressure), assist with transfers and positioning using proper clinical technique, and support hygiene and mobility needs as part of a documented plan of care. Because a nursing assistant's training includes infection control and body mechanics specific to patient care, an agency can often assign a CNA to higher-acuity clients than it would assign an unlicensed caregiver. Certified nursing assistants are also common in assisted living communities and skilled nursing facilities across Arizona, where these same scope-of-practice lines apply. What a CNA still cannot do is interpret those vital signs clinically, change a treatment plan, administer medication, or perform any task that calls for nursing judgment. That line stays with the licensed nurses supervising the CNA's work.

A licensed practical nurse holds an actual nursing license issued by the Arizona State Board of Nursing, which puts real clinical authority in their hands that a CNA does not have. An LPN can typically administer oral and many injectable medications, perform routine wound care and dressing changes according to an established plan, monitor a client's condition, and report changes to the supervising registered nurse. What an LPN in Arizona generally cannot do is perform the initial nursing assessment, build a plan of care from scratch, or manage IV medications without additional certification. A practical nurse works under the direction of a registered nurse or physician rather than independently, which is the core distinction between an LPN and an RN.

A registered nurse carries the broadest legal scope of practice of anyone who might come to your door. Only an RN in Arizona can perform the initial clinical assessment, build and revise a plan of care, administer IV medications and other complex treatments, manage high-acuity wound care, and use independent nursing judgment to catch a subtle change before it becomes a hospitalization. Registered nurses are also the only providers legally allowed to delegate and supervise the LPNs and CNAs working on a case, which is why the RN is ultimately accountable for everything happening under a plan of care. That authority is the foundation of Skilled Nursing Care delivered by an RN-led team: every client has a registered nurse leading their care, not a caregiver working alone or a rotating roster of names who never learn the household.

The right answer usually depends on acuity, not preference. If your loved one mainly needs help with daily routines and company throughout the day, a caregiver may be enough. If there's a wound to track, medication to manage, or a new diagnosis to understand, that need has already moved into licensed nursing territory. Most home care and nursing agencies rotate caregivers and nurses through a roster of clients, and standard home health also caps how much time each nurse can spend with a patient, so families often end up meeting a new face every few weeks even as needs are changing underneath them. Prata Health's model works differently: every client is matched with one registered nurse who becomes part of the family, learns the home, and coordinates directly with physicians, surgeons, and discharge planners rather than handing that coordination back to an already-stretched family. Families who want to see how our concierge nursing works usually start with a conversation about what their loved one actually needs today, not a fixed service package.

Whether your family needs help with daily routines or a registered nurse managing a complex recovery, the right match starts with an honest conversation about what your loved one actually needs. Request a Consultation to talk through the level of care that fits.
