NUR215 EXAM QUESTIONS AND ANSWERS A+ GRADED
Reservoir
Where pathogens live and multiply, the source of infection
Portal of Exit
any body opening on an infected person that allows pathogens to leave. Can be bodily
fluids, coughing, sneezing, diarrhea, seeping wounds, tubes, and iv lines
Mode of transmission
a way that the causative agent can be transmitted to another reservoir or host where it
can live
Portal of Entry
a way for the causative agent to enter a new reservoir or host. Eyes, nares, mouth,
vagina, cuts, scrapes, wounds, surgical sites, etc.
Incubation phase
time of infection until manifestation of symptoms; can infect others
Prodromal phase
appearance of vague symptoms, not all disease have this stage
Convalescence phase
tissue repair phase, return to health
Local
occurs in limited region (e.g. urinary tract infection)
Systemic
Spread via blood or lymph, affects many regions
Acute
rapid onset of short duration
Chronic
Slow development, long duration
Latent
Infection present with no discernible symptoms (HIV/AIDS)
Standard Precautions
CDC precautions used in the care of all patients regardless of their diagnosis or
possible infection status; this category combines universal and body substance
precautions
Contact precautions
practices used to prevent spread of disease by direct or indirect contact
Airborne precautions
Methods of infection control that must be used for patients known or suspected to be
infected with pathogens transmitted by airborne droplet nuclei. Negative pressure room
and N95 and surgical mask for when patient is transported
Droplet precautions
pathogen is spread via moist droplets, same as those for contact along with mask & eye
protection within 3ft of client
Nonspecific immunity
protects the body from disease in general
Specific immunity
