The question of what a nurse practitioner can actually do in the exam room is messier than most patients realize, and frankly messier than many new NP students realize until they start applying for jobs. Scope of practice is not one rule. It is fifty-one rules, since Washington D.C. has its own framework alongside the states, and each one draws the line in a slightly different place.
One NP in Oregon can open her own clinic, write a prescription for Adderall, and sign a death certificate before lunch. Another NP with the exact same degree, working in Texas, cannot legally write that prescription without a supervising physician's name attached. Same training, same boards, completely different ceiling.
This article walks through the three buckets of state authority, the specific tasks that come up over and over again in NP forums and patient questions, and the documents you can or cannot sign as a nurse practitioner. If you are studying for boards or weighing a job offer in a new state, the rules below are what actually shape your day-to-day.
You will see Adderall come up a lot. That is not an accident. Stimulant prescribing is the single most-Googled question about NP authority, and it is a useful proxy for understanding how scope works in general. If your state lets you sign that Adderall script alone, it almost certainly lets you do a lot of other things alone too.
A quick note on terminology before we dive in. "Nurse practitioner" and "advanced practice registered nurse" (APRN) are often used interchangeably, but APRN is the broader legal umbrella. APRN covers four roles: nurse practitioner (NP), certified nurse midwife (CNM), clinical nurse specialist (CNS), and certified registered nurse anesthetist (CRNA). State scope laws usually regulate all four together, though some states give CRNAs broader authority than NPs because of the surgical context. When this article says "NP scope of practice," the underlying statute almost always reads "APRN scope of practice," with NP-specific carve-outs.
Let us start with the big picture. The American Association of Nurse Practitioners (AANP) divides every state into one of three categories. Full Practice Authority, Reduced Practice, and Restricted Practice. These are not just labels. They control whether you need a collaborative agreement with a physician, whether you can run an independent clinic, and in many cases whether you can prescribe controlled substances at all.
The trend over the last decade has been one-way. States keep moving toward fuller authority, never the other direction. Since 2020 alone, New York, Delaware, Kansas, Utah, and Massachusetts have expanded NP scope. The pandemic accelerated this because rural areas simply ran out of physicians, and state legislatures had to decide whether patients would get no care or NP-only care. NP care won that argument almost everywhere it was tested.
Still, the map is uneven, and you cannot assume your neighbor's rules apply to you. An NP licensed in Arizona who moves to California is dropping from full authority to restricted, even though both are West Coast states. The patient does not change. The medicine does not change. Only the paperwork around you changes.
That is why understanding which tier your state sits in is the first thing you do when you accept a new job, and the first thing you should research before you even start applying. Recruiters will not always volunteer this information because they are filling a role, not advising you on career mobility. You have to ask.
One more layer of complexity: even within a single state, hospital systems often add their own scope restrictions on top of the state law. A Full Practice Authority state allows you to prescribe Schedule II controlled substances alone, but a specific hospital may require a co-signing physician for any controlled substance order. That is the hospital's bylaws, not the state. You can negotiate around hospital policies during contract talks. You cannot negotiate around state law.
Yes, a nurse practitioner can prescribe Adderall in most US states. Adderall is a Schedule II controlled substance, and any NP with a valid DEA registration and the appropriate state authority can write the prescription. The catch is the state authority piece. In Full Practice states, the NP signs alone. In Restricted states, the NP may need a supervising physician's name on the chart or even a co-signature. A handful of states still bar NPs from Schedule II entirely, though that list is shrinking fast.
Before we get into procedures and signatures, the three practice tiers deserve a closer look because every other answer flows from them. The structure cards below break down what each tier actually means in practice, with examples of states in each bucket. Read these carefully if you are job hunting. The difference between Full and Restricted is not theoretical.
It changes your malpractice premium, your earning ceiling, and whether you can hang your own shingle. Malpractice rates alone can run 30 to 50 percent higher for NPs working independently in Full Practice states, simply because the insurer is now covering more risk. That cost is normally baked into your contract or absorbed by the practice, but it shapes the financial math of independent practice in subtle ways.
The state-by-state map also matters for travel NPs and per-diem clinicians. A travel NP picking up a 13-week contract in a Reduced Practice state needs to know in advance whether the collaborative agreement is handled by the staffing agency, the receiving hospital, or the NP personally. Locum tenens NPs are paid well partly because they take on this administrative burden.
The contract should spell out who arranges the collaborator, who pays for the collaborator's time, and what happens if the collaborator suddenly leaves the practice mid-assignment. These are not hypothetical concerns. They come up regularly in NP recruiter forums and are the most common reason a travel contract gets canceled before the first shift.
NPs evaluate, diagnose, order tests, and prescribe (including controlled substances) under the sole authority of the state board of nursing. No physician supervision or collaborative agreement required. 27 states plus DC, including Oregon, Washington, Arizona, Colorado, New Mexico, Nevada, Idaho, Montana, Wyoming, North Dakota, South Dakota, Nebraska, Iowa, Minnesota, Hawaii, Alaska, Vermont, New Hampshire, Maine, Connecticut, Rhode Island, New York, Delaware, Maryland, Massachusetts, Kansas, and Utah.
NPs can diagnose and prescribe, but at least one element of practice requires a regulated collaborative agreement with a physician. Often the limit is on Schedule II prescribing or starting a brand new practice. States include Illinois, Indiana, Kentucky, Louisiana, Mississippi, Alabama, Ohio, Pennsylvania, New Jersey, West Virginia, Wisconsin, Arkansas, and Utah's transitional period.
NPs must work under physician supervision or delegation for at least one core function (evaluation, diagnosis, treatment, or prescribing). The most restrictive states are California, Texas, Florida, Georgia, North Carolina, South Carolina, Tennessee, Virginia, Michigan, Missouri, and Oklahoma. In these states, opening a solo NP practice is either illegal or heavily regulated.
Now to the meat of what people actually want to know. The questions below come straight from the most-searched NP queries: can a nurse practitioner prescribe Adderall, can nurse practitioners diagnose, can nurse practitioners do surgery, can a nurse practitioner do pap smears, can a nurse practitioner intubate, can a nurse practitioner sign a death certificate, can a nurse practitioner fill out disability paperwork.
Each one has a real answer, but the real answer almost always starts with "it depends on the state." The tabs below collect the most common categories of NP authority so you can scan them quickly. If you are a patient reading this to figure out whether your NP can help you, the short version is: yes, almost certainly, but ask your NP directly about anything that involves controlled substances or formal signatures, because those are where state quirks bite.
NPs in all 50 states can prescribe non-controlled medications. For controlled substances, the picture splits by DEA schedule and state law. Schedule II drugs (Adderall, Ritalin, Vyvanse, oxycodone, fentanyl) are the tightest tier. Most states allow NP Schedule II prescribing, but a few like Arkansas, Missouri, and Oklahoma require additional documentation or a supervising physician's co-signature. Schedule III to V prescribing (testosterone, codeine combinations, tramadol, benzodiazepines like Xanax and Ativan) is permitted in every state for licensed NPs with a DEA number. Buprenorphine for opioid use disorder is also legal for NPs after they complete the required training, though the X-waiver requirement was removed in 2023.
Yes, nurse practitioners can diagnose patients. Diagnostic authority is built into the NP role across all 50 states. NPs order labs, imaging, and diagnostic tests, interpret results, and assign ICD-10 codes for billing. They diagnose acute conditions like strep throat and pneumonia, chronic disease like diabetes and hypertension, and mental health conditions like ADHD, depression, and anxiety. Some specialty diagnoses (rare cancers, complex neuro cases) are typically referred to a specialist, but that is a clinical judgment call, not a legal restriction. In Restricted Practice states, the NP's diagnosis is often co-signed by the supervising physician for billing purposes, but the diagnostic act itself is the NP's.
NPs perform a wide range of procedures depending on certification and state. Routine office procedures include pap smears, IUD insertions, skin biopsies, joint injections, suturing lacerations, incision and drainage of abscesses, and casting. Acute care NPs (ACNP) intubate, place central lines, insert chest tubes, and run codes in hospital settings. NPs do not perform major surgery. They cannot operate independently in the OR. However, they routinely assist in surgery as first or second assist, especially in cardiothoracic, orthopedic, and neurosurgery. The line is operative versus assistive. An NP can suture a closing wound. An NP cannot remove a gallbladder.
NPs sign most clinical documents that physicians sign, including prescriptions, lab orders, imaging orders, referrals, work and school notes, FMLA paperwork, disability paperwork, and home health certifications. Death certificates are a state-specific question. As of 2025, NPs can sign death certificates in roughly 40 states. The remaining states still require a physician signature, though several have legislation pending. NPs can sign DNR orders and POLST forms in most states. NPs cannot sign certain federal forms that specify "physician," though Medicare has been expanding NP signature authority steadily, including home health face-to-face certifications since 2020.
Notice how often the answer in those tabs hinges on the state. That is not vague writing. That is the actual structure of NP regulation in the United States. There is no federal scope of practice for nurse practitioners. The DEA gives you a controlled substance registration, but only if your state allows that schedule for NPs in the first place. Medicare sets billing rules, but only your state board can revoke or grant your prescribing authority.
The whole system layers federal rules on top of state rules, and the state rules win when they conflict. Even within Medicare, there is a category called "incident to" billing where an NP's services are billed under a supervising physician's NPI for a higher reimbursement rate. That is purely a billing mechanism, not a scope rule. The NP is still the one providing care.
One area where federal and state rules genuinely tangle is buprenorphine prescribing for opioid use disorder. The federal X-waiver requirement (which limited the number of patients an NP could treat) was eliminated by the Consolidated Appropriations Act of 2023, so the federal cap is gone. But your state may still have its own buprenorphine training requirements, and your hospital may require specific credentialing before you can write that script. Same drug, three separate gatekeepers. Welcome to NP scope.
Another quiet driver of NP scope is the certification body. The ANCC (American Nurses Credentialing Center) and AANPCB (American Academy of Nurse Practitioners Certification Board) both certify family nurse practitioners, but the population focus written into your certificate matters at the state level. An FNP certificate covers patients across the lifespan.
An AGPCNP certificate covers adolescents through older adults. If you accept a pediatric job with the wrong certification, that is a scope problem even if your state would otherwise let you do the work. Always match the role to the population focus on your boards credential, not just to your degree.
If you have made it this far and you are still not sure where your state lands, the checklist below is the fastest way to nail down the answer. It is the same process used by NP recruiters and credentialing departments when they onboard a new hire in an unfamiliar state. None of these steps are optional.
They are the difference between a smooth start and a six-month delay because you assumed a prescribing rule that did not apply. Credentialing offices have seen every variation of this mistake, but board investigators have less patience. "I thought the rule was the same as my old state" is not a defense if a complaint is filed against your license.
Most NPs who are mid-career and considering a move treat scope of practice as a career decision, not just a legal one. Salary follows scope to a surprising degree. A Full Practice state NP running an independent clinic in Colorado can clear $180,000 to $250,000 with autonomy over their schedule. A Restricted Practice NP in Florida working in a corporate primary care clinic typically tops out lower because the supervising physician is paid out of the same revenue.
The pros and cons below summarize what you trade when you choose one environment over the other. Lifestyle matters too. Independent practice means you eat what you kill, including the bad weeks. Employed practice means a steadier paycheck and someone else worries about overhead, billing, and the cleaning service.
Beyond pure income, scope shapes the kinds of patients you see. NPs in Full Practice states are more likely to serve rural and underserved populations, because they are the only provider for fifty miles. That role can be exhausting, but it also produces the most clinically versatile NPs in the country.
By contrast, NPs in highly restricted urban states often work in narrow specialty roles where the depth of expertise is high but the breadth is limited. Neither path is inherently better. They produce different kinds of careers and different kinds of clinicians. Knowing which one you want makes the state-tier question feel less abstract.
One last point that does not fit neatly into a tab or a card. Telehealth has changed the calculus on scope of practice in a way that is still settling. An NP licensed in a Full Practice state can sometimes treat patients in a Restricted Practice state, but only under specific compact agreements or temporary licensure programs. The Nurse Licensure Compact (NLC) covers RN licensure across 41 states, but APRN compact licensure is newer and only operational in a handful of states as of 2025.
If you are considering a telehealth role, verify both the state where you are licensed and every state where your patients sit. Telehealth violations of scope are one of the fastest-growing categories of board discipline. Controlled substance telehealth rules added another layer when the DEA tightened the original COVID-era flexibilities, and the final framework continues to evolve.
The bottom line is that nurse practitioner scope of practice is wider than most patients assume and more state-dependent than most NPs are taught in school. You can prescribe Adderall, diagnose ADHD, perform pap smears, assist in surgery, intubate in an ICU, sign disability paperwork, and in most states sign a death certificate. The asterisk is always your state law.
Before you do any of those things in a new setting, pull the actual statute, talk to your board, and confirm with your employer's legal team. Scope is not a memorization game. It is a verification habit you build over your whole career. The NPs who treat it that way protect their license, expand their authority safely, and never get caught flat-footed when the rules shift.
The questions below address the specific scope-of-practice issues that come up most often in NP communities, patient forums, and recruiter interviews. If you have a question that is not covered here, the safest answer is almost always to consult your state Board of Nursing directly, since they are the final authority on what your license allows.
State boards usually publish FAQ pages, but those pages lag the actual statute. When in doubt, go to the legislation itself and look at the most recent amendments. Then call the board's APRN advisor and confirm verbally. Document the conversation in writing, with the name of the person you spoke to and the date. That paper trail is how senior NPs protect themselves when scope rules shift mid-career.
If you are still in school or just sitting for boards, treat scope of practice as part of your professional identity, not just a topic to memorize for the exam. Read your state's Nurse Practice Act front to back at least once. Subscribe to your state Board of Nursing's newsletter.
Attend at least one annual scope-of-practice update from a state or national NP organization. NPs who do these three things consistently are the ones who end up shaping policy, opening practices, and mentoring the next wave. NPs who skip them tend to get surprised by rule changes and feel boxed in by limitations they did not even know existed.
Finally, remember that scope of practice is not just about what you are allowed to do. It is also about what you should do. A Full Practice state lets you treat almost anything, but smart NPs still refer when a case is outside their comfort zone or training depth. Independence comes with the responsibility to recognize your own limits.
The most respected NPs in any practice tier are the ones who use the full breadth of their authority while staying humble about the cases that need a different specialist. That balance is what makes the profession credible, and it is what keeps patients safe regardless of which state line they happen to live on.
