chapter 7 Flashcards
medical asepsis is also called
medical technique
surgical asepsis is also called
sterile technique
what is a spore
a round body that is formed when conditions are unfavorable for its growth and lie dormant.
spores is used as?
a surviving technique
what is the purpose of a culture test?
to identify the organism
what is the purpose of a sensitivity test?
determine the sensitivity of the bacteria to an antibiotic
what is a complication of a viral disease?
it is not killed by antibiotics
what is the preferred way to decontaminating hands on a regular basis?
Alcohol based hand rub
Examples of health care associated infection-
UTI, surgical wound infections, respiratory tract and bloodstream.
Examples of systemic infection-
Aids, influenza, sepsis, etc.
Examples of localized infection-
appendicitis, UTI, arthritis.
Describe inflammatory response-
Inflammation is a protective vascular reaction or mechanism that causes. : A: increased blood flow B: WBC attack pathogens- result in pus formation. C: increase body temperature destroy pathogens
How can you control the spread of health care associated infections?
by educating staffs on aseptic practices.
what standard precautions would you use when handling soiled linen-
gloves only.
what is the purpose of reporting needle stick injuries-
so that appropriate treatment against HEP. B can began.
what is the best technique to break the chain of infection
hand hygiene
before beginning care of the patient, the nurse would wash hands for how long?
15-30 seconds.
antimicrobial wipes are a substitute for alcohol based on hand sanitizers?
False
what are the 3 things involved in hand washing?
soap, water and friction
when hands are more soiled, wash hands for how long?
2 minutes
when do you wear gloves?
when touching blood, body fluids, excretions and contaminated items.
how often would you change a regular mask?
20 - 30 minutes
where do you disregard a used syringe?
proof container
when transporting a patient in respiratory isolation-
patient wears a surgical mask
what are the principles of sterile technique -
1-6
how do you pour solutions to the sterile field-
by holding the bottle with the palm against the label.
what is sterilization?
a method that kills all microorganisms including spores.
how do you clean up a body fluid spill-
wear gloves and spray the fluid with 10% bleach
increased WBC is a sign of-
infection
What I the prodromal stage-
non specific s/s to specific s/s. contagious. EXAMPLE: low grade fever, fatigue. etc
break the chain, you can prevent the spread
TRUE
Helps determine the appropriate transmission based on precaution
TRUE
Determines the type of ABT for an organism
FALSE
determine the points at which the infection can be stopped or prevented
TRUE
Determines how an infection is spread
TRUE
Recognition of the chain of infection provides information about which patients will most benefit from isolation precautions
FALSE
What is the goal of contact precaution
to prevent the spread of infectious microorganism
when wearing latex gloves, what is an important consideration
asses the patient for latex allergy
if a patient is unsure about latex allergy, what is a question you would ask to find out about the allergy to latex?
are you allergic to tropical fruits?
what is the best way to protect the patient from HAI
hand hygiene
how do you handle linens?
- treat all linens as infectious
- hold linens away from uniform
- do not shake linens - spreads germs
- keep linens off the floor
a damp cloth can be used to wipe of overbed table
TRUE
Who are at risk of infection-
very young, weakened by any kind of illness or immune compromised (aids, cancer patients, receiving chemotherapy, radiations, trauma, etc)
An example of a surgical asepsis used by a nurse -
- insterting urinary cathedral
- suctioning
- sterile wound care
proper hand washing is apart of surgical asepsis
FALSE, surgical hand washing is.
disinfecting contaminated surfaces
FALSE
applying principles of sterile technique
TRUE
performing routine environmental cleaning
FALSE
what is the reason to avoid artificial nails, when working
because they harbor germs
a common signs of systemic infection
- fever
- leukocytosis (increased WBC) normal = 5000- 10,000 is seen in infection
- malaise (generalized discomfort)
- aneroxia (loss of appetite)
- N/V
- lymph node enlargement
how can you protect a susceptible nurse from infections-
- immunization, NOT hand washing or PPE because it is about resistance to germs. GERMS can enter by a needle stick so, nurse needs to take HEP. B vaccine
objective sign of ear infection -
purulent drainage, not hearing a buzzing sound
pain is an example of subjective or objective data
subjective data
example of a localized wound infection
redness in the area
how do you dispose off a used needle
dispose of used syringe with needle in the sharps container.
-never re cap, to avoid injury
what are the guidelines for neutropenia precations
- no fresh fruits or flowers
- no visitors with infection
- no rectal tempretures, suppositories, enema, no urniary cathedrals
- use mask and gloves
- use soft tooth brush
- observe signs of infections
order of putting on PPE
gown, mask gloves
order of removing PPE
gloves, gown, mask
what protective messaures/ airborne precautions are used when caring for a TB patient
wear N-95 or particulate respirator mask
-negitive pressure room
HEPA air filters
caregivers wear a mask when entering the room
std precaution is not a transmission based precation
TRUE
a client worth a WBC count below 5000 or an immunosuppressed, will be in what type of room
positive pressure room
ringworm is caused by
fungi
what is a fomite
contaminated object
what are the sign of acute infection
- pyrexia (fever)
-chills
-leokcytosis
malise
N.V
lymph node enlargement
what is an example of supra or secondary infections
Seen as white patches on the tounge
when do you get a supra infection
after an ABT
what PPE should be worn while suctioning
eyewear
mask
gown
gloves
