nursingKnow the role of each type of nursing professional

A hospital is not just made up of doctors. Quite the opposite! It is the various employees of the place, with their respective and important functions, that make the hospital work correctly and with maximum efficiency.

Among these indispensable employees are nurses. But did you know that there are several types of nursing professionals, each with their own role to play? Well, now, know the role of each type of nursing professional and learn why it is substantial for the smooth running of the hospital environment.

Nursing professionals and their functions

Care and attention: These are two words that synthesize the basic functions of any nurse, regardless of their specialty. It is these professionals who know, better than anyone, how to comfort and support a patient in the conditions presented by him. After all, being sick does not only require physical health care but emotional care as well, requiring total awareness and affection from nurses.

However, although every nursing professional needs to watch over and assist patients, it is not up to everyone to perform certain specific activities. That is when different types of nursing professionals come in. All of these professionals are part of the health team and promote health in different care environments.

Our College Nursing Help professionals have compiled this list of nursing professionals and their assignments to help you understand this career.


The nurse itself is the professional who is at the top of the nursing hierarchy. In order to practice the profession, it is necessary to have a higher education diploma with up to 5 years of duration.

Among its main functions, which are exclusive to nurses, the following can be highlighted:

  • is responsible for the care that requires higher levels of scientific and technical knowledge;
  • prescribes drugs established in the health unit;
  • prepares patients for  medical care;
  • personally cares for patients who are in a critical health level, such as those admitted to Intensive Care Units (ICUs);
  • performs procedures on patients (bladder catheterization, insertion of the peripherally inserted central catheter, orogastric catheter);
  • assesses wounds and chooses the type of dressing to be used;
  • perform nursing diagnoses and nursing prescriptions;
  • Delivery assistance during delivery.

However, nurses are responsible for administrative issues as well, such as organization and direction of nursing services; general supervision of auxiliaries and technicians; control of hospital infections and damage to care; training and capacity building; participation of architectural projects within health facilities; hiring nursing staff.

Nursing Technician

Next in the hierarchy is the nursing technician. In order to practice the profession, it is necessary to have completed high school and a technical course diploma lasting 2 years.

Its functions, although as important as that of the nurse, are concentrated at the basic and medium levels of care. In other words, they are aimed at baseline patients or in semi-critical health stages.

This professional can assist in the treatment of patients in the ICU or in the postoperative period, as long as they are supervised by the nurse. He assists the nurse in planning care activities at all levels of complexity.

In addition, it is your responsibility: giving vaccines, performing patient hygiene, and administering medications.

Nursing Assistant

To become a nursing assistant, you only need Elementary School and a basic course diploma lasting 1 year.

Its functions are focused on routine, repetitive, and less complex activities. He is always supervised by the nurse. The common functions of a nursing assistant include the following:

  • prepare patients for consultations, exams, and treatments;
  • perform prescribed treatments;
  • provide hygiene, comfort, and food care;
  • Ensure security. of the patient;
  • Perform disinfection and sterilization activities.


Although less mentioned and known, there are also midwives, requiring a course with a diploma of at least 2 years to carry out their profession.

The midwife is always accompanied by the obstetric nurse (focused on pregnancy) so that the delivery takes place correctly and with all the necessary care. In addition, it is up to the midwife to provide assistance after the operation, taking care of the mother and the newborn.


The doula is the professional who provides physical, emotional, and informational support to women before, during, and after labor.

During pregnancy, the doula guides the couple about expectations regarding childbirth and postpartum and helps the woman prepare for labor in different ways.

During labor, the doula is the intermediary between the health team and the couple. It helps the woman to find comfortable positions, deal with the pain, and understand the medical terms and techniques used, in addition to helping the father to act at that moment.

She is not considered a nursing professional because she does not perform any medical care and does not care for the newborn. Her duties are solely accompanying parturient.

The importance of the clinic manager in the separation of activities

The manager of a clinic, in general, is largely connected to administrative issues, checking that everything goes smoothly and in the best possible way. Among the activities performed by him, is the supervision of all nursing professionals.

This is one of their most important functions, after all, each professional must exercise their specific and private professions, not being able to perform procedures that do not fit their area. In this way, the group of professionals can work in harmony and with maximum efficiency.

It is necessary that the entire health team understands the performance of each nursing professional so that the activities within the health establishment are divided and delegated correctly. What should also happen in relation to other health professionals (physiotherapists, doctors, nutritionists, speech therapists)?

Areas in which nursing professionals work

Contrary to what many people think, nursing professionals can work in areas other than hospitals and clinics. The role of the nurse has also expanded to the areas of auditing, consulting, research, teaching, and management.

The areas of activity of nursing professionals influence:

Hospitals, clinics, and laboratories: All levels of nursing professionals work in direct assistance to patients at different levels of complexity. The nurse can also work in the sector of management, continuing education, infection control, and worker health within hospitals;

Health Centers: The nursing team is part of the Family Health Program, which is carried out by SUS Basic Health Units. They act in actions of prevention, promotion, and recovery of family health in an integral and continuous way;

Teaching and research: Nurses who choose to follow the academic area are dedicated to different areas of study. They can act as undergraduate and graduate professors, research advisors, and participants in the editorial team of scientific journals;

Worker‘s health: Nurses and technicians can specialize in the field of occupational nursing, which aims to prevent and promote the health of employees in the workplace. The professional works within companies, assessing specific risks and implementing health programs for workers;

Audit: The nurse who works in the audit area works inside or outside the hospital with project control, an inspection of the use of materials and medicines, preparation of hospitals for quality certification and project control;

Home care: Home care is provided by different nursing professionals, with the aim of providing care to patients in their own homes. They can act individually or by home care companies.

Nursing professionals are directly connected to patients ‘ daily lives. If it were not for these extremely capable and resourceful employees, the hospital environment would certainly not be the same, as they are the ones who directly participate in the recovery of every life that passes through the hospital.
