ASEPSIS Flashcards
Given diseases for contact precautions
C. diff; MRSA; scabies; Hep A; shigella; impetigo
What is a disinfectant?
An agent that kills a pathogen other than spores.
The inflammatory response is another type of nonspecific defense name it’s 5 characteristics
- Pain
- Swelling
- Redness
- Warmth
- Impaired function of the part if severely injured.
What is a susceptible host?
Someone at risk for infection
Name the 3 major types of T-cells
- Helper T-cells (helps with the function of immune system)
- Cytotoxic T-cells (attack and kill microorganisms)
- Suppressor T-cells (stops helper-T and cytotoxic T-cells from working)
PEP for Hep C
Anti-HCV and ALT at baseline and 4-6 mo after exposure
What’s the 1st stage of the inflammatory response ?
Vascular and cellular response
• The blood vessels at site of injury constricts resulting in a release of histamine which then causes dilation of smaller blood vessels, which then causes more blood flow to the area. This is characterized by signs or redness and heat. Vascular permeability increases at the site. Fluid, proteins and leukocytes leak into interstitial spaces. This is characterized by swelling and pain. Pain is caused from the accumulating fluid against the nerve endings.
List the 6 links to chain of infection
- RESERVOIR (where it lives)
- MODE OF TRANSMISSION (how it will be transferred)
- PORTAL OF EXIT (nose or mouth, anus, open wound)
- ETIOLOGIC AGENT (The microorganism “culprit”)
- SUSCEPTIBLE HOST (the victim)
- PORTAL OF ENTRY (where it enters)
What is occupational exposure?
Skin, eye, mucous membrane or parenteral contact with blood or other infectious material.
What is sterilization?
A process that destroys “ALL” microorganisms including spores and viruses.
Give diseases for airborne precaution
Measles (rubeola), varicella (including disseminated zoster), and TB.
Occupational Safety and Health Administration (OSHA) is?
Publishes and enforces regulations to protect healthcare workers from occupation injuries.
Give diseases for droplet precautions
Diphtheria (pharyngeal), mycoplasma pneumonia, pertussis; mumps; rubella; streptococcal pharyngitis; pneumonia or scarlet fever in infants; and pneumonic plague, N. meningitidis
What are the 2 types of specific defenses?
- Antibody-mediated “B” (humoral)- Responds against extracellular phases of bacterial and viral infections
- Cell mediated “T (cellular)- When exposed to antigen the lymphoid tissue releases large amounts of activated T-cells into the lymph system
What to do if PEP for HIV negative?
Discontinue PEP
Types of reservoirs
- Humans, animals, plants, food, water, feces, environment
* “CARRIER” Person or animal carries without clinical signs of disease.
PEP for Hep B
Anti-HBs testing after last vaccine dose
HBIG and/or Hep B vac within 1-7 days post-exposure
Name 6 ways to reduce a person’s susceptibility for infection
- Hygiene (flossing, bathing, shampooing)
- Nutrition
- Fluids
- Sleep
- Stress
- Immunizations
