| excessive H+ ions are retained | metabolic acidosis |
| co2 is not exhaled and increases in the body | respiratory acidosis |
| thereis a decreased of h+ ions | metabolic alkalosis |
| co2 is exhaled excessively and causes hyperventilation | respiratory alkalosis |
| caused by external factors such as viruses, chemical, or radiation exposure | mutations |
| determining the priority of care | triage |
| severe systemic allergic response which left untreated can result in death | anaphylaxis |
| sudden onset severe in intensity and usually short in duration | acute |
| less severe and has a duration longer than six months | chronic |
| comes and goes and usually has a brief duration and is not often isgnificant | transient |
| usually generated by nerve damage | intractable |

| not celled require a living cell to enter and to reproduce | virus |
| single celled animals most live in water | protozoa |
| unicellular or multicellular structure which decompose matter in soil | fungi |
| multicellular animals free lining and non pathogenic | worms |
| multicellular animals which serve as vectors | arthropods |
| natural population of microorganisms living on or in us | normal flora |
| BACTERIA THAT LIvE IN SPECIFIC SITES AND DO NOT CAUSE DISEASE | RESIDENT FLORA |
| bacteria that are found periodically on or in body | transient flora |
| symptoms are evident | symptomatic |
| no symptoms evident | asymptomatic |
| confined to one area of the body | localized |
| pathogen has spread throughouat the body by way of the blood or lymph | systemic |
| bacteria are present in the blood and are being circulated throughout the body | bacteremia/septicemia |
| an infection made possible by a primary ingection that has lowered the hosts resistance | secondary |
| infections that are acquired in the hospital | nosocomial |
| period of exposure before symptoms appear | incubation |
| vague non specific symptoms may appear | prodromal |
| specific symptoms of the illness appear | invasion |
| the height or worst of the disease | acme |
| the host recovers or death occurs | recovery |
| nosocomial infection caused by the patients own normal flora | enogenous |
| an outbreak of a disease with more than the usual number of cases in a given period of time | epidemic |
| an outbreak of a disease in a population with a expeccted or usual number of cases in a given period of time | endemic |
| an epidemic that has spread throughout several countries | pandemic |
