People often conflate nurse practitioners and nursing assistants, as both provide patient care. However, each serves unique needs within health care environments, with distinct training paths, responsibilities, and levels of authority. Anyone working either role would do well to understand exactly what each role requires of them, as well as how insurance protects careers within each field.

This guide offers insight into the roles of a nurse practitioner and a nursing assistant, highlighting key differences.
What do nurse practitioners do?
Nurse practitioners (NPs) are advanced practice registered nurses who hold graduate degrees. As part of primary care services, nurse practitioners evaluate patients, order tests, and diagnose conditions; others specialize in pediatrics, mental health or gerontology.
Nurse practitioners in many states can operate autonomously. In others, they must work collaboratively with a doctor. Either way, nurse practitioners take on considerable clinical responsibilities. This may include taking health histories, performing exams and interpreting lab results, prescribing medications where allowed, managing ongoing care plans and informing patients of their healthcare needs.
Nurse practitioners make clinical decisions that shape patient care, so their day-to-day involves a certain amount of risk that could result in a legal claim. A missed detail or a communication mistake can lead to a complaint even when the NP acted in good faith. Professional Liability insurance helps protect their finances and career during these situations. Nurse practitioners can get this type of coverage through BizInsure, which offers policies that support steady work and peace of mind if a claim is filed.
What Are the Duties of a Nursing Assistant?
Certified nursing assistants (CNAs) aid nurses by helping patients complete daily tasks. CNAs work in hospitals, long-term care facilities, rehabilitation facilities and home health settings where their duties require direct patient care.
Standard functions of certified nursing assistants may include:
- Bathing and dressing patients as needed.
- Providing meals.
- Changing linens when necessary.
- Providing mobility assistance as necessary
- Recording vital signs as required
CNAs spend most of their day at a patient’s bedside observing changes in their condition. This makes them vital in providing comfort and safety to those in their care, but it can pose risks โ uch as handling errors, documentation problems, or communication gaps with patients or families.
Professional Liability insurance gives CNAs steady protection. Even a small claim can bring unexpected legal costs, and coverage helps manage those expenses.
While nurse practitioners and nursing assistants both play key roles in maintaining patient health, their services differ significantly in four key areas. Among these are he following.
- Education and training: Nurse practitioners (NPs) complete advanced clinical education beyond the registered nurse level. The pathway typically includes earning a Bachelor of Science in Nursing (BSN), becoming a licensed RN, gaining clinical experience, and then completing a graduate NP program โ most commonly a Master of Science in Nursing (MSN) or Doctor of Nursing Practice (DNP). CNAs complete a short state-approved training program (often 75+ hours) and pass a competency exam to provide basic hands-on care under nurse supervision.
- Scope of practice: Nurse practitioners specialize in diagnosing and treating medical conditions, while CNAs support basic daily needs and assist with clinical tasks.
- Decision-making within professional boundaries: CNAs typically make independent clinical decisions, while NPs base their choices on care plans created by nurses and providers.
- Legal risk: Nurse practitioners shoulder greater responsibility for diagnosing and treating their patients, while Certified Nursing Assistants perform direct patient care tasks that put them at risk; both roles benefit from professional liability policies to cover potential claims.
Potential legal claims
Claims can arise from documentation errors, miscommunication, or unexpected events and can result in financial losses for employees who did nothing wrong. Professional Liability insurance provides essential protection in the event of an incident that was not your responsibility, offering peace of mind when an unfortunate event affects your financial well-being.
Professional Liability insurance for health practitioners
Nurse practitioners and nursing assistants support patients in different ways, and each role has its own demands and benefits. Knowing these differences can help you choose the path that fits your skills and goals.
