Master the POC in CNA (Plan of Care) for your exam. Understand the key differences in duties for a CNA vs medical assistant and explore roles.
The POC in CNA stands for Plan of Care — a legally binding, individualized document that directs every aspect of a resident's or patient's care. It specifies goals, interventions, schedules, and preferences tailored to one specific person. Nothing generic. Nothing assumed. Planning to advance to RN? Our free NCLEX practice test 2026 covers all Next Generation NCLEX formats including case studies and matrix questions.
The plan of care CNA staff follow is created by the interdisciplinary care team: the registered nurse, attending physician, physical and occupational therapists, dietitian, and social worker each contribute to its development. CNAs do not write the POC — but that distinction does not reduce their responsibility to it. Legally and ethically, CNAs are required to follow the POC exactly as written during every shift.
Why does this matter for your exam? Because CNA test questions frequently test whether candidates understand the boundary: a CNA carries out care defined in the POC, documents what they observe, and reports any deviation or change in condition to the supervising nurse. Acting outside the POC — even with good intentions — is a scope-of-practice violation.
Understanding the fundamental duties of a Certified Nursing Assistant starts here: following the POC is the foundation of safe, compliant care. To test your grasp of how this applies in clinical scenarios, prepare with a free CNA practice test.

The RN conducts the initial head-to-toe assessment, formulates nursing diagnoses based on clinical findings, and writes the official Plan of Care. All updates to the POC — including changes triggered by CNA observations — flow through the RN.
The physician provides the overarching medical direction: ordering medications, diagnostic tests, and treatments that anchor the POC. CNAs never take orders directly from physicians — all physician directives reach the CNA through the RN and the written care plan.
The CNA carries out the hands-on tasks documented in the POC: ADL assistance, repositioning, vital signs, and feeding. Critically, CNAs spend the most direct time with patients, making them the first line of detection when a patient's condition deviates from POC expectations.
Physical, occupational, and speech therapists add rehabilitation goals — such as ambulation targets or swallowing protocols — directly to the POC. Social workers coordinate discharge planning, family communication, and community resources, ensuring the POC extends beyond the facility.
Before touching a single patient, pull the current POC and note any updates added since your last shift — medication changes, new therapy goals, or revised repositioning schedules can appear overnight.
Complete bathing, grooming, dressing, and feeding exactly as written — if the POC specifies a mechanical soft diet or two-person transfer, follow it precisely. Deviating without authorization is a scope violation.
Use every ADL interaction as a clinical observation window. Note skin integrity during bathing, respiratory effort during repositioning, and appetite changes during feeding — these are the cna duties plan of care data points the RN cannot gather firsthand.
Any deviation from the poc - cna plan of care baseline — new confusion, skin breakdown, refusal of care, or vital sign shift — must be verbally reported to the charge nurse before the end of that care episode, not at shift end.
Record what you did, what you observed, and the patient's response — not what you intended to do. If a task was refused or could not be completed, document the reason. Incomplete documentation creates legal and clinical liability.
Care conferences occur at admission, at 14 days, and quarterly in skilled nursing facilities per federal regulation. Your direct-care observations — appetite trends, mobility progress, behavioral patterns — are irreplaceable data that the RN, physician, and therapists need to update the POC.
The NNAAP exam tests your understanding of the CNA's role in the POC — not as a creator or modifier, but as an observer, follower, and reporter. When a resident's condition differs from the POC, your first action is always to report to the nurse.
A Patient Care Technician (PCT) is not exactly the same as a CNA, but CNAs can work as PCTs. PCTs typically have additional training beyond CNA certification, including phlebotomy, EKG monitoring, and IV care. Most employers require PCT candidates to hold an active CNA certification as a prerequisite. Learn more about role differences at CNA Career Paths & Specializations.
A patient care technician (PCT) and a CNA are related but not identical roles. CNAs focus on basic daily living assistance and vital signs, while PCTs perform additional clinical tasks such as drawing blood and reading EKGs. A CNA certification is often the foundation for becoming a PCT, making it a natural career progression. Explore advancement opportunities at CNA Career Paths & Specializations.
Yes, becoming a Certified Nursing Assistant is a solid career choice with strong job stability, as the Bureau of Labor Statistics projects continued demand for CNAs in hospitals, nursing homes, and home health settings. CNAs gain hands-on clinical experience that can serve as a stepping stone to LPN, RN, or other healthcare roles. Median annual pay varies by state and setting, with opportunities for advancement.

CNAs can assist with basic wound care tasks such as applying simple dressings under the supervision of a licensed nurse, but they cannot independently assess, treat, or make clinical decisions about wounds. Complex wound care, debridement, and prescription dressing changes are outside the CNA scope of practice and must be performed by an RN or LPN. CNAs must always follow their state's nurse practice act and facility policies. Practice related skills at CNA Basic Nursing Skills Quiz.
Patient care technicians and CNAs share overlapping duties but are distinct roles — PCTs generally have a broader clinical skill set that includes phlebotomy and cardiac monitoring in addition to standard CNA tasks. Many PCT positions require candidates to already hold a valid CNA certification. If you are starting out, earning your CNA credential first is the most common path.

A caregiver and a CNA are not the same, though their daily tasks can look similar. Caregivers typically work in home or assisted living settings and may not hold formal state certification, while CNAs have completed a state-approved training program and passed a competency exam to earn their certification. CNAs are legally authorized to perform clinical tasks like measuring vital signs and catheter care that unlicensed caregivers cannot.
