Nursing includes more than a dozen distinct roles, ranging from nursing assistants who help patients with daily tasks to doctoral-level practitioners who diagnose illnesses and lead healthcare organizations. The differences come down to education, licensure, and scope of practice. Here’s a clear breakdown of every major type of nurse, what each one does, and what it takes to become one.
Certified Nursing Assistants (CNAs)
CNAs are the entry point into nursing. They provide hands-on, basic patient care: helping people bathe, dress, eat, and move around. They also take vital signs and report changes in a patient’s condition to the nurses supervising them. CNAs work under the direction of registered nurses or licensed practical nurses.
Becoming a CNA typically requires completing a state-approved training program, which can take as little as four to twelve weeks, followed by a competency exam. The median pay for nursing assistants is $39,430 per year. Many people use the CNA role as a stepping stone into higher nursing positions while gaining real clinical experience.
Licensed Practical Nurses (LPNs)
Licensed practical nurses, called licensed vocational nurses (LVNs) in California and Texas, sit one level above CNAs. They can perform more clinical tasks: administering medications, inserting catheters, changing wound dressings, and monitoring patient health. Depending on the state, LPNs may supervise CNAs, but they generally work under the guidance of a registered nurse, advanced practice nurse, or physician.
LPN programs require a high school diploma or GED and take about one year to complete at a community college, hospital, or technical school. After finishing the program, you pass the NCLEX-PN licensing exam. The median salary for LPNs is $62,340 per year. LPNs are commonly found in nursing homes, home health agencies, and outpatient clinics.
Registered Nurses (RNs)
Registered nurses make up the largest segment of the nursing workforce and carry significantly broader responsibilities than LPNs. RNs assess patients, create care plans, administer treatments, educate patients and families, coordinate with other healthcare providers, and supervise CNAs and LPNs. They are the central hub of patient care in most settings.
There are two main educational paths to becoming an RN. An Associate Degree in Nursing (ADN) takes two to three years, usually at a community college. A Bachelor of Science in Nursing (BSN) takes four years at a university. Both paths lead to the same licensing exam (the NCLEX-RN), but a growing number of hospitals prefer or require a BSN. The median pay for registered nurses is $93,600 per year.
Where RNs Work
Hospitals are the most visible workplace, but RNs practice in a wide range of settings: private practices, public health agencies, primary care clinics, home health care, nursing homes, outpatient surgery centers, schools, mental health agencies, hospices, the military, insurance companies, and healthcare research organizations. The setting you choose shapes your daily work as much as your title does.
RN Clinical Specialties
Once you’re a registered nurse, you can specialize in a particular patient population or type of care. Specialization usually involves additional training, on-the-job experience, and often a board certification exam. The most common specialties include:
- Pediatric nursing: caring for infants, children, and adolescents
- Medical-surgical nursing: the broadest specialty, covering patients before and after surgery and those with a wide range of medical conditions
- Critical-care nursing: working in intensive care units with the most unstable patients
- Oncology nursing: supporting patients through cancer diagnosis, treatment, and recovery
- Psychiatric-mental health nursing: caring for patients with mental illness and substance use disorders
- Palliative care nursing: managing pain and quality of life for patients with serious or terminal illness
- Adult gerontology nursing: focused on the health needs of older adults
These specialties exist at both the RN and advanced practice level, so you can deepen your expertise over time without switching careers entirely.
Advanced Practice Registered Nurses (APRNs)
APRNs hold a master’s or doctoral degree and have the broadest scope of practice in nursing. They can diagnose conditions, order tests, prescribe medications, and manage patient care independently in many states. There are four recognized APRN roles, each with a distinct focus.
Nurse Practitioners (NPs)
Nurse practitioners provide primary, acute, and specialty care across the lifespan. They assess, diagnose, and treat illnesses and injuries, often serving as a patient’s main healthcare provider. NPs can specialize further by population: family (FNP), pediatric, adult-gerontology, psychiatric-mental health, and others. A family nurse practitioner who passes the ANCC board certification exam, for example, earns the FNP-BC credential.
Certified Registered Nurse Anesthetists (CRNAs)
CRNAs provide the full range of anesthesia and pain management services. They administer anesthesia for surgeries, monitor patients throughout procedures, and manage post-operative pain. In rural areas, CRNAs are frequently the sole anesthesia provider.
Certified Nurse-Midwives (CNMs)
Nurse-midwives provide primary care, gynecological services, and reproductive health care. They manage pregnancies, deliver babies, and provide well-woman care throughout a patient’s life, not just during pregnancy.
Clinical Nurse Specialists (CNSs)
Clinical nurse specialists work in a dual role. They diagnose and manage patients directly while also serving as expert consultants to other nurses on a unit, driving practice changes and making sure care is based on the best available evidence.
The median pay for nurse practitioners, nurse anesthetists, and nurse-midwives is $132,050 per year. Becoming any type of APRN requires earning a Master of Science in Nursing (MSN) at minimum, which takes roughly 1.5 to 2 years after a BSN. Many programs now require or encourage a Doctor of Nursing Practice (DNP) degree.
Education Levels Beyond the BSN
An MSN opens the door to APRN clinical roles, but also to positions in nursing leadership and nursing education. MSN programs accept RNs with a BSN (2 to 3 years to complete) or RNs with an ADN (2 to 4 years). There are even direct-entry MSN programs designed for people who hold a bachelor’s degree in a non-nursing field; these take 3 to 4 years and include preparation for the RN licensing exam along the way. Admission is competitive, typically requiring a minimum GPA, specific prerequisite courses, RN licensure, and professional experience.
A doctorate is the highest level of nursing education. A Doctor of Nursing Practice (DNP) is practice-focused, preparing nurses for top clinical or leadership roles. A PhD in nursing is research-focused, aimed at generating new knowledge and advancing the science of the profession. Either takes an additional three to four years beyond a master’s degree.
Nurses Who Work Outside Patient Care
Not every nurse works at the bedside. Nursing skills translate into a surprising number of non-clinical careers. Nurse educators teach in nursing schools and hospital training programs. Nurse managers and directors oversee units, budgets, and staff. Legal nurse consultants review medical records for law firms. Case managers coordinate long-term care across multiple providers.
One of the fastest-growing non-clinical paths is nursing informatics, where nurses bridge the gap between clinical care and health information technology. Job titles in this space range from systems analyst and IT training manager to chief nursing informatics officer. These roles draw on a nurse’s understanding of clinical workflows to design, implement, and improve the electronic systems hospitals depend on.
Choosing the Right Path
The type of nurse you become depends on how much time you want to invest in education, what kind of work energizes you, and how much autonomy you want over patient care decisions. A CNA program can have you working in weeks. An LPN certificate takes about a year. An ADN gets you into bedside nursing in two to three years, and a BSN in four. If you want to diagnose and prescribe, you’re looking at a master’s or doctorate and six to eight years total. Each level builds on the one before it, so you can start working early and continue your education over time without starting over.
The salary range reflects this progression clearly: from roughly $39,000 for nursing assistants to $62,000 for LPNs, $94,000 for RNs, and $132,000 for APRNs. Specializing within any of these levels, or choosing a high-demand setting, can push your earning potential higher still.
