NURS 317 Practice Exam questions and Answers
communicable disease
specific infectious agent or its toxic products that arises through transmission to a susceptible
host
- decreased morbidity and mortality bc of vaccines and improvement of nutrition and sanitation
and living conditions
- John snow and cholera street pump
- while we are at a prevention, control, and early detection response lots of people die still
mainly in resource poor countries (lots from acute diarrheal deaths)
CD classification
clinical:
diarrheal, respiratory, CNS, cardiovascular, sepsis
microbiological:
bacterial, fungal, viral, parisitic, prion
means of transmission:
contact, food or water borne, airborne, vector, perinatal
reservoirs:
human, animal, soil, water
public health classifications:
STBBI's, respiratory, enteric borne or food borne or water borne, vaccine preventable
Antimicrobial Resistance
,organisms change in a way that reduces or eliminates
natural phenomenon
intrinsic: naturally resistant
acquired: after being exposed is resistant
Why report CD's
reduce the prevalence
it is shared responsibility (local public health departments have the primary responsibility)
notifiable disease
provincial and territorial and national: dictate which diseases must be reportable and then they
also must report them and submit data annually
PHAC -> WHO
local: active surveillance, infection control nurses
- CHN must monitor and report, education, HP, research, policy
four host factors that influence the spread of disease
1. resistance: the ability of the host to WITHSTAND infection
2. immunity: a resistance to an infectious agent
3. community immunity: resistance of group of people
4. infectiousness: a measure of the potential ability of an infected host to transmit the infection to
other hosts
, Minnesota health wheel
type of information you can use in surveillance
case definition, contact definition, contract tracing, mode of transmission, contact identification,
active and passive surveillance
case-finding: locates individuals and families with identified risk factors and connects them to
resources
delegated functions
Direct care tasks a registered professional nurse carries out under the authority of a health care
practitioner as allowed by law. Delegated functions also include any direct care tasks a registered
professional nurse entrusts to other appropriate personnel to perform
innate vs acquired immunity
innate = non-specific and involves protective mechanisms already present in the body at birth to
facilitate immunity (coughing, sneezing, muscous membranes)
acquired = specific, mechanisms for immunologic memory
- active: protection produced by person's own immune response (natural disease or vaccine)
- passive: transfer of antibodies produced by one human to another (temporary, breast feeding,
placenta)
anti-vax movement
- comes from Dr. Paul Wakefields that showed link between MMR vaccine and autism
