While you might associate registered nurses with hospital work, the truth is that there are opportunities for RNs in a variety of workplaces. Depending on your specialty and interests, your work as an RN could take you beyond healthcare facilities and into schools, corporate environments, or even into the air as a flight nurse.

Healthcare is filled with surprising opportunities for RNs, according to Emma Leigh Geiser, an RN with 10 years of experience in nursing who is currently working as a coach and speaker in the nursing field.

“A career in nursing can be anything you want it to be,” says Geiser. “You can work ‘per diem,’ picking how often you want to work, or you can crush the glass ceiling and become a member of the C suite.”

Some nurses pursue advanced degrees to become nurse practitioners and nurse anesthetists, says Geiser. “Often, the direction you think your career will go changes when you see what opportunities truly exist in the healthcare system.”

Plus, the demand for RNs is steadily growing. The U.S. Bureau of Labor Statistics (BLS) predicts 5.6% growth in the field through 2032.

What do RNs do? (An experts take)

Registered nurses (RNs) play a crucial role in providing and coordinating patient care. They are responsible for assessing and monitoring patients, administering treatments and medications, educating individuals and the community about health conditions, and offering valuable advice and emotional support to patients and their families.

You might work in a fast-paced department like the ER, helping patients with serious injuries or illnesses, or in a mental health unit, helping patients manage conditions like anorexia or depression. You could even work with patients virtually as a telehealth nurse.

“The responsibilities of a nurse are different in each department and position,” says Gesier. “That’s what makes (the job) so versatile. Most often, the RN is the direct caretaker for patients in the hospital,” managing patients’ daily activities, medications, assessments, and scheduled procedures and operations. RNs work closely with fellow healthcare staff and physicians to ensure they know about and understand patient updates and care plans.

As an RN, your daily responsibilities are as varied as the field itself, but there are a few constants. In most RN roles, you’ll:

  • Monitor and record patient vital signs
  • Monitor and record patient progress
  • Create care plans for patients
  • Administer medications and treatments
  • Assist with procedures
  • Administer and monitor IV medications
  • Educate patients and answer their questions
  • Perform wound and skin care
  • Draw blood and collect lab work

Beyond the basics, where you work could make a huge difference in your role. For example, RNs who work in physicians’ offices also take on some administrative work, while RNs who work in the operating room might assist with surgical procedures.

What types of jobs can I get as an RN?

Once you’ve been licensed as an RN, the door is open to a variety of nursing jobs, like pediatrics or hospice nursing. While nurses might start at the bedside, a little time, experience, and an interest in exploring new opportunities can quickly lead you to the job of your dreams.

“Most nursing positions require you to have some type of critical care or bedside experience,” explains Geiser. “Once you get a year or two of experience, there are multiple opportunities to move away from patient care positions. Many nurses even work remotely from home in triage, case management, and quality review.”

We’ve rounded up some common opportunities for RNs and broken them down so you know what to expect. From entry-level work to aspirational roles, check out some of the possibilities below.

MSN-level public health nurses can help create public health policies, such as smoking cessation campaigns, to help improve community health.

Addiction Nurses
(sometimes called Substance Abuse Nurses)

What you’ll do: Work alongside gastroenterologists to treat patients with a variety of diseases, injuries, and other conditions related to the digestive system.

Minimum degree required: ADN or BSN, though many employers prefer or require nurses to have at least a BSN.

Who it’s a good fit for: Gastroenterology would be a good fit for nurses who are interested in how the digestive system affects other areas of our health and vice versa.

Job perks: You get to help people recover or manage gastroenterology conditions which afflict many people. You get to have a direct impact in helping improve their quality of life.

Opportunities if you pursue a higher degree or certification: Getting certified as a Certified Gastroenterology Registered Nurse (CGRN) from the American Board for Certification of Gastroenterology Nurses (ABCGN) demonstrates your expertise and commitment to the field, and could lead to better jobs and higher pay.

Does the degree I earn make a difference?

As an RN, you need either a two-year Associate Degree in Nursing (ADN) or a four-year Bachelor of Science in Nursing (BSN). Both the degree you hold and your specific role can impact your day-to-day work, career growth, and salary as an RN. For example, although you can be licensed as an RN with an associate degree or a bachelor’s degree, more leadership roles and growth opportunities are open to nurses with a BSN.

If you’re already practicing as a licensed practical nurse (LPN), there are a couple paths available if you’re looking to become an RN. The LPN-to-ADN program will build upon your existing LPN education through an associate’s, while the LPN-to-BSN program will earn you a bachelor’s. Completion of either will qualify you to take the NCLEX, the national RN licensing exam.

Some people come to nursing after working in a related healthcare field. The paramedic-to-RN pathway is a popular one for people who enjoy the medical aspects of a paramedic role but are looking for the varied opportunities a nursing career can provide.

No matter your designation, nearly all nurses—including RNs—need a certain level of continuing education courses to keep their license current. Though not all states have these requirements, your employer might require continuing education to maintain a specialty certification.

FAQ: All about RN duties & responsibilities

What does an RN do in a hospital?

An RN’s duties in a hospital are going to depend on their exact position, department, experience and education level. In general, their job duties aren’t much different than RNs that work in other settings. One of the biggest differences between hospital RNs and RNs that work in other settings is the kind of health issues they treat.

Although hospitals also have many outpatient units, they are typically where patients go for more serious or life-threatening medical issues. Therefore, RNs who work in hospitals often do more inpatient care, such as treating pre and post-operative patients, assisting with surgeries, working in trauma or emergency care, helping deliver babies and more.

What are RNs not allowed to do?

An RN’s exact legal scope of practice depends on the laws of the state that they work in. However, there are some things than RNs can’t do no matter where they practice. RNs cannot:

  • Make medical diagnoses
  • Certify the death of a patient
  • Prescribe medication (in most states)
  • Perform surgeries or other invasive procedures

How many hours do RNs work?

An RN’s schedule depends on their work setting and the individual needs of their position. Just like other jobs, it is common for RNs to work approximately 40 hours per week. However, some RNs may work part-time (less than 30 hours per week) and others may choose to pick up extra shifts. It is also common for RNs to work longer shifts but fewer days per week. Three 12-hour shifts per week, for example, is a common schedule for RNs that work at hospitals.

Where can RNs work?

RNs are needed in just about any place where people live, work and learn. They are essential to the healthcare system and are employed by a variety of institutions, including but not limited to:

  • Hospitals
  • Medical offices
  • Nursing homes
  • Home healthcare services
  • Outpatient clinics
  • Schools
  • Churches
  • Government offices
  • Community centers
  • Military bases
  • Non-profit organizations and clinics
  • Large corporations or companies

What technology do registered nurses use?

Medical technology is constantly evolving, and nurses must be able to keep up with the changes in order to deliver the best patient care. RNs use many different types of technologies on a daily basis, such as:

  • Electronic health records that digitize a patient’s medical history, immediate medical needs, diagnoses, medications, and much more. Nurses must be able to read and edit these records daily.
  • Telehealth and other medical apps which allow nurses to communicate with and even treat patients electronically.
  • Medical devices which are used to monitor and/or treat patients, like wearable devices that track vital signs, automated IV pumps, smart beds, and more.
