UNIVERSAL BODY SUBSTANCE PRECAUTIONS
Prevention of Transmission of Human Immunodeficiency Virus
and Other Blood-Borne Pathogens in Health Care Settings
Only blood, semen, vaginal secretions, and possibly breast milk have been implicated in
transmission of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and other
blood-borne pathogens.
Blood is the single most important source of transmission of blood-borne pathogens in
health care settings. Infection control efforts must focus on preventing exposures to
blood.
Although the risk is unknown, universal precautions also apply to tissues and to
cerebrospinal fluid, synovial fluid, pleural fluid, peritoneal fluid, and amniotic fluid.
Universal precautions do not apply to feces, nasal secretions, sputum, sweat, tears,
urine, and vomitus unless they contain visible blood. Although universal precautions do
not apply to these body substances, the wise nurse wears gloves for protection from
other infections.
Precautions are used for all patients. (Reason: It is impossible to know which patients
are infected with such conditions as HIV, HBV, or other infectious agents.)
Gloves are worn whenever the health care worker may come in contact with blood,
body fluids containing blood, and other body fluids to which universal precautions apply.
(Reason: Diseases can be carried in the body substances.)
Wear gloves at all times if you have any break in the skin of your hands. If you have an
exudative condition, such as weeping dermatitis, you must be evaluated before working
with patients and patient care equipment. (Reason: You may be at great risk of
contracting a disease; you might also spread disease.)
Change gloves after each contact with a client. (Reason: The gloves may be
contaminated.)
Wash your hands and skin surfaces immediately and thoroughly if they are
contaminated with blood or body fluids. (Reason: Proper washing will help to stop the
spread of infection.)
Wear a gown or apron when clothing could become soiled. (Reason: To prevent
spread of infection to yourself or others.)
