chapter 41 Medical Asepsis

Terms in this set (51)

*Trauma -Injury or illness lowers the body's resistance
*Age- The very young and the very old have reduced denfenses
*Inactivity-The person who is ill usually does not get much exercise, which weakens the body's defenses
*pre-existing disease, generally poor health or frequent illness; infection or chronic illness lowers the body's defenses
*Poor nutrition /inadequate hydration. The ill person may be malnourished, dehydrated (not enough fluid in tissues or circulation), or overhydrated (too much fluid, fluid retention).Lack of protein hinders the immune system in tissue repair and production of antibodies. Impaired skin integrity is often present , as well as inadequate circulation.
*Stress or emotional shock. Increased stress increases the body's cortisone levels, reducing resistance to disease(sometimes by immunosuppression)
*Fatigue .The person who is extremely tired cannot effectively fight off disease .
*Invasive therapy .The term invasive means any therapy that enters or invades the body (by a means other than normal), through a break or incision , an instrument that enters an otherwise sterile area. Examples of invasive therapy include surgery , injections, intravenous therapy , urinary catheterization ,and tracheostomies (a tube inserted into the trachea to open an airway).
*Frequent use of broad-spectrum antibiotics. Microorganisms in a person's body may develop resistance to antibiotic therapy after repeated exposure to the same antibiotic. Those antibiotics are later ineffective against the resistant pathogen.
*Inappropriate use of antibiotics- not finishing antibiotics, taking left overs, or unnecessarily prescribed antibiotics>This lead to development of resistant strains of pathogens.
*Inadequate primary and secondary defenses.The body's primary defenses may be altered because of break in the skin ,low white blood cell count, an autoimmune disorder, or diminished lung function.
*Immunosuppressive situations . The client's immune system may be inadequate as a result of chemotherapy for cancer or bone marrow transplant, administration of high doses of steroids to reduce inflammation , radiation, or an autoimmune disorder such as AIDS or agammaglobulinemia.
