Licensure follows the patient
The location that matters for telehealth is generally the patient’s, not yours. Sitting in one state and caring for a patient in Arkansas generally means you need authority to practice in Arkansas — via compact privilege or an Arkansas license. See telehealth: patient in another state.
The law that governs this in Arkansas
Caring for a patient located in Arkansas is practice in Arkansas, so it is Arkansas’s own nurse practice act that defines what you may do and the Arkansas State Board of Nursing that applies it. That act is Arkansas nursing licensure law (Arkansas State Board of Nursing).
The compact itself is separate law. Arkansas adopted it at Ark. Code Ann. §§ 17-87-601 to 17-87-604 (Nurse Practice Act, subch. 6 — Nurse Licensure Compact), which is what allows a multistate license issued elsewhere to reach Arkansas at all — the practice act still decides what you may do once it does.
Compact status is not the only consideration
Even where a multistate license reaches Arkansas, your employer and the Arkansas State Board of Nursing may impose additional requirements, and some roles carry their own rules. Compact status answers one question — it is not a blanket authorization to practice remotely.
APRN telehealth is separate
The compact covers RN and LPN/LVN licenses only. If you work as an APRN, your advanced-practice authority is granted state by state and is not carried by a multistate RN license — a point that catches out a lot of remote NP roles.
Since when has a compact license worked in Arkansas?
Nurses holding another state’s multistate license have been able to practice in Arkansas since January 19, 2018. It has been a member long enough that most guidance you find will be accurate on this point.
