Exam 3 Section 3 Flashcards
Infections acquired in the course of medical care
Most often applied to infections contracted in an acute care hospital
nosocomial infection
In the US there are approx. _________ patients annually who contract nosocomial infections
2 million
Risk factors for nosocomial infections
age(elderly & really young), heredity, nutritional status, stress, inadequate rest and exercise, health history, inadequate defenses
A nosocomial infection that results from a particular treatment or therapeutic procedure
A pt may not develop symptoms of the illness until leaving the health care environment
Can trace back to how the infection was contracted
Iatrogenic Nosocomial infection
The _________ is the most common site of nosocomial infection and is associated with the use of indwelling catheters
urinary tract
when body fluids are touched directly from person to person
direct transmission
Fomite = syringe or dressing (any inanimate object)
Vehicle = food, water, drugs, blood
Vectors = infected animals or insects
Droplet = nose or mouth of an infected host
Airborne = comes from evaporated residue left from droplet
indirect transmission
to eliminate as best as possible all microorganisms with the use of soap, water, friction, and chemical disinfections
disinfectant, removes most
medical asepsis
microorganisms and their spores have been completely destroyed by means of heat or chemical process
Removes everything
surgical asepsis
The use of _________ is the number one way to reduce/break the cycle of the spread of infection
hand hygiene
When are you required to wear gloves?
if there is a chance of coming into contact with bodily fluids
There are four major groups of microorganisms that are known to produce diseases:
– Bacteria
– Fungi
– Viruses
– Parasites and prions
elements needed to transmit infection
- infection agent
- environment to live & multiply
- portal of exit from the reservoir
- means of transmission
- portal of entry into a new host
HIV usually results in ____, a disease that is currently
incurable and has a high mortality rate.
AIDS
A patient must reach the ___ stage of the disease before it is classified as having AIDS. Once reaching this stage, ___ to ___ die within __ years
5th, 80% to 90%, 3
An inflammation of liver cells that is initially acute, but in some cases render the disease to the chronic carriers
viral hepatitis
types of hepatitis
HVA, HVB, HVC, HCD, HVE
Health care workers most often contract hepatitis B from ________ ______
needlestick injuries
has also become more prevalent in recent
years and has become the most common bloodborne infection in the United States
Hepatitis C
Chronic disease caused by the spore–forming Mycobacterium tuberculosis bacterium
tuberculosis
In ____, the CDC published updated and expanded guidelines to prevent the transmission of infection control for all persons working in health care settings
2007
This method of transmission occurs when microbes are spread on evaporated droplets that remain suspended in air or are carried on dust particles in the air and may be inhaled by persons in that room or air space.
airborne infection isolation
vital signs include
– Body temperature
– Pulse
– Respiration
– Blood pressure (BP)
body temp is controlled by the
hypothalamus
Changes in the body’s physiology occur when the body temperature fluctuates __ to __ degrees
2 to 3
normal body temp for adult (14 years and over)
97.8°F to 99.0°F
normal body temp for child (5-13 years)
97.8°F to 98.6°F
normal body temp for infant (3 months to 3 years)
99.0°F to 99.7°F
A patient whose body temperature is elevated above normal limits is said to have a “fever,” also known as
pyrexia
Four areas of the body to measure temperature:
– Oral (mouth under tongue)
– Tympanic (ear)
– Rectum (anal opening)
– Axillary (armpit)
normal oral temp
98.6°F (37°C)
normal tympanic temp
97.6°F (36.4°C)
normal rectum temp
99.6°F (37.5°C)
normal axillary temp
97.6°F to 98°F (36.4°C to 36.7°C)
Nine Locations to Measure a Pulse
- Apical: apex of the heart (heard with a stethoscope)
- Radial: at the wrist at the base of the thumb
- Carotid: neck
- Femoral: groin
- Popliteal: posterior knee
- Temporal: front of ear
- Dorsalis Pedis: top of foot
- Posterior Tibial: inner side of ankle
- Brachial: groove of elbow
most common locations for pulse
radial pulse an carotid pulse
pulse point for sterile invasive procedures
popliteal, posterior tibial, and pedal pulse
avg pulse rate for adult
60 to 90 bpm
