What Is PRN in Nursing? Definition and Frequently Asked Questions
What does PRN mean in nursing?
PRN comes from the Latin phrase pro re nata, meaning “as needed” or “as the situation arises.”
In staffing, a PRN nurse works when a hospital, clinic or other healthcare facility needs additional coverage. PRN employees generally do not follow the same fixed weekly schedule as full-time nurses.
A facility might request PRN coverage because of:
- Employee illness
- Vacation
- Parental leave
- Seasonal demand
- Increased patient volume
- Unfilled positions
- Training days
- Emergency events
PRN is a work arrangement, not a separate nursing license. A PRN registered nurse must still meet the same licensing and professional requirements as another RN performing the same duties.
What does PRN mean on a medication order?
PRN can also appear in clinical documentation or medication instructions. In this context, it means a treatment or medication is given as needed under defined conditions.
A valid order should include relevant instructions, such as the reason, dose, route, frequency and any maximum limits required by policy.
For example, a PRN medication order may authorize pain medication when a patient reports pain that meets specified criteria.
This use of PRN is different from PRN employment, although both use the idea of responding to a need rather than following an automatic schedule.
What does a PRN nurse do?
PRN nurses perform many of the same clinical duties as permanent nurses in comparable positions.
Responsibilities may include:
- Assessing patients
- Monitoring vital signs
- Administering medications
- Updating medical records
- Providing treatments
- Supporting procedures
- Communicating with physicians
- Educating patients and families
- Coordinating discharge
- Responding to emergencies
- Following safety and infection-control procedures
PRN nurses may need to adapt quickly because assignments, units and coworkers can change between shifts.
How does PRN scheduling work?
Scheduling policies differ by employer. Some facilities post open shifts that PRN nurses can request, while others contact nurses directly when coverage is needed.
A PRN agreement may specify:
- Minimum shifts per month
- Weekend requirements
- Holiday requirements
- Availability expectations
- Cancellation procedures
- Eligible departments
- Shift length
- Required training
- On-call obligations
- Pay differentials
PRN does not always mean a nurse can work only when personally convenient. Employers may require a minimum level of availability to keep the position active.
How to become a PRN nurse
1. Complete an approved nursing program
The education required depends on the nursing role. Registered nurses commonly complete an approved:
- Associate Degree in Nursing
- Bachelor of Science in Nursing
- Nursing diploma program
Licensed practical or vocational nurses follow the approved pathway required in their jurisdiction.
2. Obtain nursing licensure
Graduates must meet the requirements of the nursing regulatory body in the jurisdiction where they plan to practice.
For U.S. registered nurses, this generally includes passing the NCLEX-RN and completing state licensing requirements.
3. Gain clinical experience
Some PRN roles accept newer nurses, but many employers prefer candidates with previous experience. Facilities need PRN nurses who can enter a unit and work with limited orientation.
Experience requirements depend on the specialty. Critical care, emergency, operating room and other specialized PRN positions may require relevant unit experience.
4. Maintain required credentials
Depending on the role, employers may require:
- Basic Life Support
- Advanced Cardiovascular Life Support
- Pediatric Advanced Life Support
- Specialty certifications
- Immunization records
- Background screening
- Continuing education
5. Apply directly or through an agency
PRN nurses may work directly for a hospital or facility. Some obtain assignments through staffing agencies or nursing pools.
Review scheduling, cancellation, benefits and pay policies before accepting a position.
Advantages of PRN nursing
Schedule flexibility
PRN nurses may have more control over which shifts they accept. This can help them balance family, education or other professional responsibilities.
Potentially higher hourly pay
Some employers offer higher hourly rates because PRN nurses may not receive the same benefits or guaranteed hours as permanent employees.
Experience in different settings
PRN work may expose nurses to multiple units, facilities or patient populations.
Additional income
A full-time or part-time nurse may hold a separate PRN position to earn extra income, subject to employer policies and safe working-hour limits.
Opportunity to evaluate a workplace
Working PRN can help a nurse learn about a unit’s management, culture and workflow before pursuing a permanent position.
Continued professional practice
Retired or semi-retired nurses may use PRN roles to continue working on a limited basis, provided they maintain all required credentials.
Disadvantages of PRN nursing
Unpredictable hours
Available shifts depend on staffing needs. A nurse may receive many hours during one period and very few during another.
Shift cancellation
A facility may cancel a PRN shift if patient volume changes or permanent staff become available. Cancellation policies vary.
Limited benefits
Some PRN positions do not provide health insurance, retirement contributions, paid leave or other full-time benefits.
Less familiarity
Moving between units can make it harder to learn routines, develop relationships and understand each team’s working style.
Difficult shifts
PRN nurses may be offered nights, weekends, holidays or last-minute assignments that permanent employees do not cover.
Ongoing availability requirements
A facility may require PRN employees to work a minimum number of shifts, weekends or holidays.
PRN vs. full-time nursing
A full-time nurse generally has a regular schedule, guaranteed hours and access to employee benefits.
A PRN nurse usually works according to staffing needs. The hourly rate may be higher, but income and benefits may be less predictable.
The clinical responsibilities may be the same when both nurses work in the same role and unit.
PRN vs. part-time nursing
Part-time nurses usually have a recurring schedule with fewer hours than full-time employees. They may qualify for some benefits, depending on the employer.
PRN nurses generally have less predictable schedules and work only when additional coverage is needed.
PRN vs. per diem nursing
Employers sometimes use “PRN” and “per diem” interchangeably. Both commonly describe nurses who accept shifts as needed.
In some organizations, PRN refers to an employee of the facility, while per diem refers to a worker paid by the day or shift. The distinction depends on the employer, so candidates should review the contract rather than relying on the title.
PRN vs. travel nursing
Travel nurses accept temporary assignments that may last several weeks or months. They often work a defined schedule during the contract and may receive housing or travel support.
PRN nurses commonly work individual shifts for local facilities without committing to a long assignment.
Questions to ask before accepting a PRN position
Ask the employer:
- How many shifts must I work?
- Are weekends or holidays required?
- How are open shifts assigned?
- Can the facility cancel a shift?
- Is there cancellation pay?
- Does the position include benefits?
- Which units can assign me?
- How much orientation is provided?
- Are shift differentials available?
- Can I work at other facilities?
- What happens if I decline several shifts?
- Which credentials must I maintain?
These questions can help you compare the hourly rate with the complete working arrangement.
Is PRN nursing right for you?
PRN work may suit nurses who value flexibility, already have healthcare benefits or want additional income. It may also help experienced nurses explore different units.
It may be less suitable for someone who needs predictable weekly income, guaranteed hours or employer-sponsored benefits.
Review your budget, availability, experience and tolerance for schedule changes before choosing PRN work.
Conclusion
PRN nursing provides flexible, as-needed staffing for healthcare facilities. Nurses should evaluate pay, required availability, benefits and cancellation policies before accepting this type of position.

Frequently asked questions
Do PRN nurses choose their own hours?

Can a new graduate work PRN?
Some employers hire new graduates, but many prefer experienced nurses because PRN staff may receive shorter orientation and need to adapt quickly.
Can a PRN nurse work at multiple hospitals?
Often yes, but nurses should review employer policies, scheduling conflicts, fatigue risks and any restrictions in their agreements.
