This profile summarizes the common issues and duties for a registered nurse. Nurses can work in a wide variety of health care settings or workplaces. Depending on where you live, the duties of a nurse (registered, licensed practical, aid versus other types of nursing) may vary.

Because each workplace is unique, there is no way to predict all of the possible hazards you may encounter. This summary focuses on the major job duties that most nurses would have in common when working in a hospital.

What, briefly, does a registered nurse do?

Back to top

Main duties of a registered nurse include:

  • assess, plan, implement and evaluate a patient's care along with other members of the health care team.
  • administer medications and treatments as ordered by a doctor.
  • monitor, record and report symptoms or changes in a patient's condition.
  • use proper techniques for dressing changes, insuring infection control, etc.
  • use or monitor medical equipment.
  • assist in surgery and with other medical procedures.
  • supervise nursing assistants and other nursing staff.
  • provide safety and health education to individuals and families.
  • cleaning or disinfecting patients' beds and rooms.

Some nurses may specialize in other fields such as occupational health or public health. Occupational health nurses can provide employee health education programs and care in private businesses or industries. Public health nurses offer health education through either public health departments or through home visits.

What are some health and safety hazards associated with being a nurse?

Back to top
Hazards typically fall into one of six general categories as listed below. For more information on that issue, prevention, or how to work safely with a product, click on the links where provided throughout this document.


Nurses can be exposed to contagious and infectious diseases including those that can be transmitted through the air (e.g., TB - tuberculosis), blood-borne diseases such as AIDS, hepatitis B and C and hand to hand transmission (e.g., Clostridium difficile). There is also the risk of exposure to multi-drug resistant organisms such as multi-drug resistant tuberculosis (MDR-TB), Methicillin-resistant staphylococcus aureus (MRSA) and others.

Nurses are also at risk for exposure to novel (new) viruses, such as coronavirus (COVID-19), SARS, etc.

As a consequence of the need for frequent hand washing, skin conditions such as dermatitis may occur.

Illness as the result of a needlestick injury is also a concern.


In a hospital environment, nurses may encounter:

  • various chemicals used for general janitorial cleaning as well as for disinfecting and sterilizing.
  • anesthetic gases as well as waste anesthetic gases.
  • latex (in gloves and equipment).
  • exposure to other chemicals, compressed gases, products, pharmaceuticals and medicine, including opiods and cytotoxic (anti-neoplastic) drugs.


There are many situations where physical demands involve force, repetition, awkward postures and prolonged activities. These include:

  • walking or standing for long periods of time.
  • lifting.
  • overexertion (reaching, carrying, etc.).


Nurses can be exposed to:

  • radiation: both x-rays and radiation from radioisotopes.
  • lasers.


In a hospital, there are many situations where there is equipment in various places, liquid on floors, etc. The main hazards from these situations are slips, trips and falls. There is also a risk of items falling onto the person.

Nurses may also be exposed to burns or scalds from hot sterilizing equipment, and stabs or cuts from sharp objects.


Nurses often experience forms of violence at work, including when working alone and working alone with patients.

Responsibility of care, emergencies, and the need to make certain decisions when others cannot be found can increase the stress experienced by some people. Exposure to serious traumatic events (or consequence of the event) is another cause of stress. As with most emergency services, there will be long periods of quiet or routine interrupted abruptly by periods of intense stress or activity.

Most nurses work shifts or extended work days which may cause fatigue or have health effects.

However, it is important to note the positive aspects of being a nurse. It is a highly respected profession and highly valued in the community. Also, there is usually a high sense of team membership.

Are there any long-term health effects of being a nurse?

Back to top

Several target organs may be adversely affected by prolonged exposure to chemicals including the respiratory, neurologic, reproductive, dermal, and hematopoietic systems. For example, ethylene oxide has been classified by the International Agency for Research on Cancer (IARC) as a known human carcinogen (Group 1).

Other long-term health effects may include:

  • adverse effects from long-time exposure to chemicals like medications (e.g., anti-neoplastic drugs), sterilizing agents (e.g., glutaraldehyde), and anesthetic gases.
  • fatigue.
  • lower back pain.
  • diseases such as tuberculosis and hepatitis B and C.
  • infectious skin irritation and dermatoses from frequent use of soaps, detergents and disinfectants.
  • latex allergy.

What are some preventative measures that can be taken?

Back to top
  • Hand washing and routine practices and other measures are extremely important for the reduction of infections. Be sure to use moisturizers to prevent your skin from drying.
  • Learn proper techniques to avoid needlestick injuries.
  • Always use the correct personal protective equipment (PPE) or other barriers for the task. In some cases, latex gloves will not be appropriate (e.g., cleaning with certain chemicals).
  • Wear appropriate footwear (for walking/standing, as well as protection from dropped objects).
  • Learn safe patient lifting techniques - create a safe patient handling program.
  • If a job requires work in an awkward position (e.g., with hands above shoulder level) be sure to take frequent breaks.
  • Follow a recommended shift work pattern, and be aware of the hazards associated with shift work.
  • Take steps to encourage better sleep, including "good" eating habits that help encourage sleep.
  • Consider offering a debriefing or session after a critical event to help reduce the impact from stress.
  • Ask your workplace to establish safe procedures for working alone or develop procedures where this situation can be avoided altogether.
  • Keep all hallways and passages clear of clutter and equipment.
  • Install and maintain adequate ventilation for the area.
  • Keep all radiation levels to a minimum and wear a radiation dosimeter, as recommended by the radiation safety officer or regulatory authorities.
  • If work is in the nuclear medicine department or involves working with patients being treated or tested by such departments, staff should be given appropriate training to prevent or control exposure to radiation sources.

Because of the wide variety of workplaces where nursing may occur, and the vast range of activities done and materials used by nurses, all situations cannot be covered in this document.
