LVN vs RN: What Attorneys and Paralegals Need to Know About Nurse Scope of Practice

You have seen it. Thousands of pages of chart records with lots of nurses scattered in the mix. LVN, LPN, RN, BSN, MSN. At the end of the day you are left questioning who can do what, who can tell who to do what, and why can one not do what the other does. Most people outside of medicine think all nurses are the same. They see scrubs and think, nurse. But you are here because you are evaluating a case where things did not go well. And in those cases, who did what and whether they were legally allowed to do it matters a lot. These are the questions I hear most from attorneys and paralegals.

Q: Can an LVN perform the initial admission assessment?

No. An LVN can collect data, like taking a blood pressure or documenting a pulse. But they cannot synthesize that data and formulate a care plan. That is the RN's job. California is specific: the nursing assessment within 24 hours of admission must be completed by a Registered Nurse. If you are reviewing an EHR audit trail and you see an LVN completed the admission note alone, the facility violated the state Nurse Practice Act.

Q: What is the difference between LVN data collection and an RN nursing assessment under California law?

Data collection means gathering information. An LVN can do that. A nursing assessment requires the nurse to observe signs and symptoms, determine whether they are abnormal, and then act on that determination. That second part requires an RN. The California Nurse Practice Act is clear on this. If you are looking at a chart and trying to figure out who should have caught something, this distinction is where you start.

Q: When an RN delegates a task to an LVN, does the liability go with the task?

No. And this is one of the most common misunderstandings I see. The task gets delegated but the responsibility stays with the RN. This carries over from the 5 rights of delegation I covered in my UAP episode. When you are reviewing the documentation from a case, look for the subtle hints that something may have been a poorly delegated task. Was the patient stable? Was the LVN capable of that task? Was the task communicated appropriately? Was there follow-up from the RN? If any of those answers are no, you may have found your breach.

Q: What happens when an RN fails to act on a change in a patient's condition?

This is where it gets important. RNs have an independent duty to assess, monitor, and sound the alarm. The case Fraijo v. Hartland Hospital is the blueprint for this in California. Nurses gave the ordered medication but when the patient's vitals showed a profound negative shift in status, they did not reassess, did not recognize what was happening, and did not notify the physician in time. The courts affirmed that the RN's failure to monitor and report was independent negligence. They cannot hide behind the doctor's orders when their own inaction caused the harm.

Q: Can an RN refuse a doctor's order to advocate for a patient?

It depends on how they do it. An RN has a duty to advocate for the patient, but that advocacy has to be done the right way. In Finnerty v. Board of Registered Nursing, a nurse disagreed with a resident physician's order and took matters into her own hands without first raising her concerns through the proper chain of command. The court found that what she did was not advocacy, it was substituting her own clinical judgment. Advocacy means raising the concern the right way. When you see a case where a nurse claims they were advocating for the patient, look at how they did it.

Q: What can an LVN legally do in California?

LVNs in California can do a lot. They can take vitals, administer medications, collect specimens, perform wound care, insert catheters, and assist with basic respiratory care. They can give injections and start IVs under physician direction with the right certification. What they can't do is perform a comprehensive nursing assessment, formulate a care plan, work independently, or manage anything that requires clinical judgment without RN or physician oversight. There is also a newer update: as of October 2025, regulations from the Respiratory Care Board clarified exactly what LVNs can and cannot do with respiratory equipment.

Q: If an LVN performs a task outside their scope of practice and something goes wrong, who is responsible?

Potentially more than one person. The LVN can face license discipline. The RN who delegated the task may be liable for negligent delegation to an LVN. And the facility itself may be on the hook for allowing it to happen. A real example: an LVN was mixing and administering chemotherapy. The supervising physician tried to claim he was administering it on the LVN's behalf. No documentation existed to support that. The LVN faced disciplinary action. When something goes wrong, everyone in the chain gets looked at.

Q: Where can I find the official source for LVN and RN scope of practice in California?

The California Board of Vocational Nursing and Psychiatric Technicians (BVNPT) governs LVNs. The California Board of Registered Nursing (BRN) governs RNs. Both have public websites with their respective Nurse Practice Acts and publicly available disciplinary records. If a nurse has a case history, a Disciplinary Actions tab appears next to their name. You can download the exact public transcripts of the Board's investigations detailing every clinical omission they committed.
