Infection, FUND
246 Quiz 1
| Question | Answer |
|---|---|
| Body’s cellular response to injury or infection, Protective vascular activity | Inflammation |
| formation of fibrinogen and fibrin strands across the affected area. The scar is never as strong as the original tissue. | resolution of inflammation |
| occurs when a microorganism invades the host but does not cause infection | Colonization |
| disease is the infectious process transmitted from one person to another | Communicable |
| Chain of Infection (6 steps) | Infectious agent or pathogen, Reservoir or source for pathogen growth, Portal of exit, Mode of transmission, Portal of entry, Susceptible host |
| Sufficient number, Sufficiently virulent, Able to enter and survive in host, Host must be susceptible | Infectious Agents |
| agents of infection | bacteria, viruses, fungi, protozoa |
| Hepatitis A, B, C. HIV, HPV | viruses |
| E. Coli, Staph aureus, Strepto, Mycobacterium | bacteria |
| Candida | fungi |
| Falliparum (malaria) | protozoa |
| Food, Oxygen (aerobic vs anaerobic), Water, Temperature, pH, Light or dark, Open skin or mucous membranes, Respiratory tract, Urinary tract, Gastrointestinal tract, Reproductive tract, Blood | Reservoir essentials |
| Skin and mucous membranes, Respiratory tract, Urinary tract, Gastrointestinal tract, Reproductive Tract, Blood | Portals of Entry (SKIN, TRACTS, BLOOD) |
| Modes of Transmissions are | contact, vehicles, vector |
| direct contact vs indirect contact | Direct—person-person/person-source vs. Indirect—person-contaminated object |
| droplet nuclei or evaporated droplets suspended in air during coughing/sneezing | airborne |
| large particles travel up to 3 ft propelled by coughing/sneezing/talking | droplet |
| contaminated objects, blood, water, food, stethoscopes, hands | vehicles |
| Mosquitoes, Lice, Fleas, Ticks | vector |
| Elderly and very young have immune systems that are less robust, Nutritional status impacts level of resistance, Chronic diseases affect resistance, Smoking, Those who have used antibiotics inappropriately in all healthcare settings | Susceptible Hosts |
| infectious process (4 stages) | Incubation period, Prodromal stage, Illness stage, Convalescence |
| interval between entrance of pathogen into body and appearance of first symptom | Incubation period |
| Interval from onset of nonspecific Signs &Symptoms to more specific symptoms | Prodromal stage |
| Interval when manifest signs and symptoms specific to type of infection | Illness stage |
| Interval when acute symptoms of infection disappear | Convalescence |
| local infections | wound infection |
| localized infection symptoms | pain, tenderness, and heat, redness, loss of function of the area. |
| systemic infections | present in the bloodstream, lymphatics, (affects the entire body) |
| Septicemia | most common systemic infection that results in death |
| Fever (pyrogen release), elevated white blood cell count, tachycardia, weakness/malaise, cough or difficulty urinating, lymphadenopathy, anorexia with possible nausea and vomiting, possible confusion or mental status changes | systemic infections symptoms |
| Normal flora, Body defense mechanisms, Inflammation, Vascular and cellular responses, Inflammatory exudate, Tissue repair | Defenses Against Infection |
| Health Care–Associated Infection (Nosocomial) | Hospital, Community, Iatrogenic, Exogenous, |
| acquired infections | Hospital, Community |
| from a diagnostic or therapeutic procedure. | Iatrogenic infection |
| is present outside the client. | Exogenous infection |
| normal flora becomes altered. | Endogenous infection |
