QUESTIONS AND CORRECT ANSWERS
◉ what is the normal range for adult O2 saturation.
Answer: 95% or more
◉ factors that affect oxygen saturation.
Answer: anxiety, infection, shock, hypoxia, drugs, acid-base
imbalance, disease
◉ what is something to consider about oxygen saturation levels in
older adults with disease.
Answer: they may have a lower oxygen saturation level and may
require supplemental oxygen
◉ disease definition.
Answer: Infection is the invasion of a susceptible host by pathogens
or microorganisms. Infection will develop if the Chain of Infection
stays intact. This infection will ultimately result in disease.
◉ chain of infection.
Answer: -infectious agent/pathogen
,-reservoir: place where microorganism survives, multiplies, and
waits to be transferred to a susceptible host.
-portal of exit
-mode of transmission
-susceptible host
◉ acute disease.
Answer: fast onset, severe/abrupt symptoms, reversible
◉ chronic disease.
Answer: slow onset, never goes away, persists 6 months or longer
◉ HAI.
Answer: an infection that develops in a person cared for in any
setting where health care in given. the infection is related to
receiving health care
◉ iatrogenic HAI.
Answer: from a procedure
◉ exogenous HAI.
Answer: from microorganisms outside the individual (Salmonella)
, ◉ endogenous HAI.
Answer: when patient's normal flora becomes altered (C.diff)
◉ body's response to stress.
Answer: Basal metabolic rate increases as the body uses energy
stores. Adrenocorticotropic hormone increases serum glucose levels
and decreases anti-inflammatory responses. If this lasts a while, it
can cause decreased resistance to infection.
◉ inflammation.
Answer: protective vascular and cellular reaction to eliminate
pathogens and necrotic tissues.
◉ serous exudate.
Answer: Watery exudate: indicates early inflammation
◉ sanguinous exudate.
Answer: bloody
◉ purulent exudate.
Answer: Pus: indicates a bacterial infection (made up of bacteria,
neutrophils, monocytes, and WBCs)
