Introduction
On a 32-bed hospital medicine unit in an Ohio teaching hospital, two advanced practice registered nurses start the day at the same workstation. The acute care nurse practitioner carries a panel of patients on the hospitalist service. The adult-gerontology clinical nurse specialist is responsible for nursing practice across the medical division. Staff nurses call both of them "the APRN," pages meant for one reach the other, and a new hire could reasonably wonder why the hospital employs both. This comparison sets the roles side by side, ordered from formal authority down to daily work, and then argues where each role stops. The two were chosen because they share patients and are the pair most often confused by the people around them.
Table 1: Role Comparison, Ohio Hospital Medicine Service
Each row gives the clinical nurse specialist (CNS) first and the acute care nurse practitioner (ACNP) second.
1. Graduate preparation. CNS: master's or doctoral program in the adult-gerontology CNS population focus. ACNP: master's or doctoral program in the adult-gerontology acute care NP population focus. Both complete the three APRN core courses in advanced physiology and pathophysiology, health assessment and pharmacology (APRN Consensus Work Group & NCSBN APRN Advisory Committee, 2008).
2. Certifying organization. CNS: adult-gerontology CNS examination from the AACN Certification Corporation or the American Nurses Credentialing Center. ACNP: adult-gerontology acute care NP examination from the same two bodies.
3. License category. Both: Ohio APRN license, with the designation clinical nurse specialist or certified nurse practitioner.
4. Prescriptive authority. Both: authorized in Ohio, practiced under a standard care arrangement with a collaborating physician, and limited to what the collaborating physician may prescribe (Ohio Rev. Code § 4723.431, 2024; Ohio Rev. Code § 4723.481, 2024).
5. Typical reporting line. CNS: the director of medical nursing or the chief nursing officer. ACNP: the hospitalist medical director, with practice oversight through the medical staff.
6. Primary focus. CNS: three spheres of impact, the patient, nurses and nursing practice, and the organization or system (National Association of Clinical Nurse Specialists [NACNS], 2019). ACNP: diagnosis and management of an assigned patient panel from admission to discharge.
7. How success is measured. CNS: division outcomes such as hospital-acquired infection rates, fall rates and practice change adoption. ACNP: panel volume, length of stay, readmissions and documentation that supports billing.
8. Posting language. CNS: "leads evidence-based practice," "consults on complex patients," "develops protocols." ACNP: "manages a census of," "admits and discharges," "performs procedures as privileged."
Note. Rows 1 to 3 rest on regulatory and certification documents; row 4 on Ohio statute; row 6 on the NACNS statement; rows 5, 7 and 8 on a review of current regional postings and the service's organizational chart, and they are the rows most likely to vary by employer.
Where the Roles Diverge
The first real divergence is the reporting line, and it follows from where each role's authority comes from. The ACNP is privileged through the medical staff to manage patients, so the hospitalist director oversees that work. The CNS's authority over nursing practice comes from the nursing organization, so the CNS reports through nursing. The organizational chart settles this row, and it explains most of the confusion on the unit: the two APRNs look alike at the workstation, but they answer to different leaders for different results.
The second divergence is focus. The ACNP's attention stays on the patients on the panel. The CNS's attention moves across all three spheres at once: a CNS who sees a patient with a new pressure injury is also asking whether the unit's turning practice failed, and whether the product formulary contributed (NACNS, 2019). The same bedside visit therefore produces a treatment plan from one role and, from the other, a practice question about the unit.
The third divergence is how each is judged. Fulton et al. (2016) surveyed 347 practicing clinical nurse specialists about 42 published CNS outcomes and found strong agreement that the outcomes matched real practice. They also found that CNSs whose job descriptions included the outcomes reported using them more. That finding makes the posting language row more than trivia. If an employer writes a CNS posting in the vocabulary of patient census and throughput, the CNS will be measured, and will likely practice, as a second ACNP.
Where the Roles Overlap
Prescriptive authority is the row where the two roles genuinely overlap in Ohio. The statute treats the clinical nurse specialist, the certified nurse-midwife and the certified nurse practitioner alike: each practices under a standard care arrangement with a collaborating physician, and none may prescribe beyond the collaborating physician's authority (Ohio Rev. Code § 4723.431, 2024; Ohio Rev. Code § 4723.481, 2024). On paper, then, the CNS on this unit could write the same orders as the ACNP.
What settles the overlap is not the statute but the hospital. Legal authority to prescribe says what the state allows; medical staff privileges say what this hospital allows this person to do on its premises. On this service the ACNP holds privileges to admit, order and discharge, while the CNS holds privileges limited to consultation and protocol-based orders. The boundary that staff experience every day is therefore an employer decision layered on top of a statute that would permit much more. This is also the row most likely to change by state, since states differ in whether they grant CNSs prescriptive authority at all.
Which Row Employers Blur Most
Of the eight rows, posting language is the one employers blur most often. Two of the regional CNS postings reviewed for this table asked the specialist to "carry a patient census when needed," which borrows the practitioner's core duty and leaves the three spheres unmentioned. A hospital that writes the role this way is not breaking any rule, since neither statute nor certification forbids it, but it is choosing a role different from the one the national statement describes. For staff on the unit, the practical fix is simple and rarely done: a one-page description of who to page for a patient problem and who to call for a practice problem, posted at the workstation both APRNs share.
Conclusion
The comparison complicated my own choice. I had assumed the difference between these roles was mostly one of setting and patient load. The table shows that the difference is one of mandate: one role is accountable for a panel, the other for a practice. That distinction matters for my plans because the outcomes a posting names are the outcomes I would be measured by, and I will read future postings for that vocabulary before I read them for salary or schedule.

How this NU501 Unit 3 example is structured
An introductory paragraph names both roles, the state and the setting, and explains why these two were chosen: they share patients and are often confused by the staff around them. The table follows, formatted to APA with a numbered title and a note beneath it listing the sources behind each row. Rows are ordered from formal authority to daily practice, so the reader moves from what documents require down to what the work looks like. The narrative takes three rows where the roles genuinely diverge and one where they overlap, and for each names the document that decides the question: a certification handbook, the state board's rules, a professional association's scope statement, or a posted vacancy. The closing paragraph reflects briefly on fit. References separate standards documents from research articles letting a reader tell which rows rest on which kind.

NU501 Unit 3 questions, answered
Which two roles work best for a comparison?
Two that share patients, settings or duties, because the boundary between them then has to be argued. A clinical nurse specialist and a nurse practitioner, a nurse educator and a staff development specialist, or a nurse manager and a director all work. Comparing roles with nothing in common, such as a nurse anesthetist and a school nurse, gives the table differences too obvious to discuss.
Can the table be the whole assignment?
Rarely. Most prompts want narrative alongside it, because a table shows differences and prose explains why they exist. Even when the instructions emphasize the table, a short analysis beneath it usually earns the interpretation marks. Check whether your section sets a length for the narrative, then keep the table itself to phrases rather than paragraphs.
How many rows should the comparison have?
Enough to cover authority, credentialing and daily practice, usually somewhere between six and ten. Fewer and the comparison misses a dimension; more and the table becomes hard to read. Every row should be one you can support with a source, and one or two rows should show genuine overlap so the narrative has something to argue about.
