A nursing team typically includes five to eight distinct positions working together on a single hospital unit, ranging from executive leaders who set policy down to assistive personnel who provide hands-on daily care. The exact makeup varies by facility and setting, but most teams share a common structure: leadership roles at the top, licensed nurses in the middle, and support staff carrying out delegated tasks under supervision.
Registered Nurses
Registered nurses are the backbone of any nursing team. About 57% of all RNs work in hospitals, where they carry out the broadest scope of clinical duties. An RN independently assesses patients, develops care plans, administers medications, and evaluates whether treatments are working. When something in a patient’s condition changes, the RN decides what to do next.
RNs also manage the workflow of the unit. They assign tasks to other licensed nurses and delegate specific activities to assistive personnel. They’re accountable for the nursing care delivered by everyone working under them on a given shift, which makes the role equal parts clinical skill and coordination.
Licensed Practical Nurses
Licensed practical nurses (called licensed vocational nurses in California and Texas) work in a dependent role alongside RNs. There are roughly 950,000 LPNs working across the country. They collect patient data, take vital signs, administer certain medications, and carry out the care plan that an RN has already created. The key distinction is that LPNs participate in assessment and planning but don’t independently create or modify care plans.
LPNs require RN supervision. They can assign tasks to other LPNs and delegate to unlicensed staff, but their supervisory authority is limited to confirming that tasks were completed according to facility policy. They cannot administer nursing services or manage the overall nursing care of a unit.
Certified Nursing Assistants
Certified nursing assistants provide the most direct, hands-on patient care on the team. They help patients with daily living activities like bathing, dressing, eating, and repositioning in bed. They also take vital signs and report changes to the nursing staff. CNAs work under the supervision of RNs and LPNs and are essential to keeping a unit running smoothly, especially on busy floors where licensed nurses can’t be at every bedside.
Becoming a CNA requires completing a state-approved training program, which typically lasts a few weeks, followed by passing a state certification exam. That certification is recognized across hospitals, long-term care facilities, and home health settings.
Patient Care Technicians
Patient care technicians overlap significantly with CNAs but carry a slightly broader skill set. In addition to basic patient care, PCTs may monitor EKG signals, assist with clinical procedures, draw blood, and perform phlebotomy or catheter care depending on facility training. They also keep patient rooms organized and provide emotional support.
PCT certification isn’t mandatory in every state, but most hospitals prefer it. Training programs build on the CNA foundation and add technical skills. In practice, the line between CNA and PCT varies by employer. Some hospitals use the titles interchangeably, while others clearly separate them with different pay grades and responsibilities.
Charge Nurses
A charge nurse is an RN who takes on shift-level leadership for a specific unit. They make patient assignments, handle bed management, troubleshoot staffing gaps, and serve as the go-to person when problems arise during a shift. Most charge nurses still carry a patient load of their own on top of these duties, though the size of that load varies by hospital.
This isn’t a separate license or credential. It’s a role assigned to experienced RNs who have demonstrated strong clinical judgment and organizational skills. On many units, several nurses rotate through the charge role rather than one person holding it permanently.
Nurse Managers and Directors
Nurse managers oversee an entire unit or department on a permanent basis. They handle hiring, scheduling, budgeting, performance evaluations, and compliance with hospital policies. While they may have clinical backgrounds, their day-to-day work is largely administrative. They’re the bridge between frontline staff and upper leadership.
Above nurse managers sit directors of nursing, who oversee multiple units or an entire nursing division. At the top of the hierarchy is the chief nursing officer, a C-suite executive who sits alongside the CEO, CFO, and chief medical officer. The CNO serves as the chief administrator for the nursing division, advocates for nurses as professionals within the organization, and plays a major role in driving patient satisfaction, quality, and safety across the entire hospital.
Advanced Practice Registered Nurses
Some nursing teams include advanced practice registered nurses, a category that covers nurse practitioners and clinical nurse specialists. Nurse practitioners diagnose conditions and prescribe treatments within their certified specialty area. In many states, they practice independently without physician supervision and carry full responsibility for their patients’ care.
Clinical nurse specialists fill a different niche. They coordinate and supervise care for patients with complex needs, evaluate the quality of nursing interventions, and provide clinical consultation to the rest of the team. Where a nurse practitioner functions more like a provider, a clinical nurse specialist functions more like an expert resource embedded within the nursing staff.
Unit Support Staff
Behind the clinical roles, nursing teams rely on administrative support to function. Health unit coordinators (sometimes called unit secretaries or ward clerks) handle the paperwork and logistics: answering phones, managing patient records, processing admissions and discharges, coordinating with other departments, and handling insurance documentation. They don’t provide clinical care, but their work keeps the information flowing so nurses can focus on patients.
Some facilities also employ certified medication aides, who are trained assistive personnel authorized to administer routine medications under nurse supervision. This role exists primarily in long-term care and assisted living settings rather than acute hospital floors, and availability depends on state regulations.
How Delegation Holds the Team Together
What makes these positions a team rather than a collection of individuals is a formal delegation process. The American Nurses Association and the National Council of State Boards of Nursing outline five “rights” that govern how tasks flow from licensed nurses to support staff: the right task, the right circumstance, the right person, the right direction, and the right supervision. A licensed nurse evaluates whether a patient is stable enough for a task to be delegated, whether the person receiving the task has the training to do it safely, and then monitors the outcome.
The one thing that can never be delegated is clinical reasoning. Nursing judgment, critical decision-making, and the interpretation of patient data always stay with the licensed nurse. A CNA or PCT can take a blood pressure reading and report the number, but deciding what that number means and what to do about it is the nurse’s responsibility. This principle is what defines the boundaries between every position on the team.
