(P) Lesson 2: Infection Control Flashcards
Process by which a pathogen enters, multiplies, and causes illness to the body
Infection
Microorganisms that cause disease are called what?
Pathogens
Non-pathogenic microorganisms on our skin and GIT
Normal Flora
T or F: Normal flora can become pathogenic
True (if they exist in a location they aren’t meant to be in)
Infection that affects only one area of the body
Local infection
Infection that affects the entire body
Systemic infection
Infection caused by one’s own flora
Autogenous infection
Diseases that spread from one person to another
Communicable disease
Infections acquired in healthcare facilities
Nosocomial infections
Microorganisms that develop resistances to specific antibiotics
Antibiotic Resistant Infections
Microorganisms that develop resistances to multiple antibiotics; aka superbugs
Multi-Drug Resistant Organisms
The continuous link in the transmission of pathogens between a source and host
Chain of Infection
The causative agent for infections that may be bacteria, protozoa, virus, etc.
Infectious Agent
The place where pathogens can grow, survive, and multiply (animals, humans, plants, soil, etc.)
Reservoir
The pathway where an infectious agent can leave a reservoir host; can be secretions from the eyes, nose, mouth, blood, feces, urine, etc.
Exit Pathway
Refers to contact that may be direct or indirect
Means of Transmission
Physical transfer from the source to the host through close or intimate contact
Direct Contact
Transfer of pathogens via an object such as bed linings, instruments, furniture, etc.
Indirect Contact
Transfer of pathogens through the mucus membranes of the host via water particles
Droplet Transmission
T or F: Droplet size is less than 5 micrometers
False (more than 5 micrometers)
T or F: Droplet pathogens do not remain suspended in the air
True
Droplet nuclei develop when the fluid evaporates in this type of transmission
Airborne Transmission
T or F: Airborne pathogens remain infective in particles larger than 5 micrometers
False (less than 5 micrometers)
T or F: Airborne pathogens can stay suspended in the air for several hours
True
A transfer via contaminated materials such as food or water
Vehicle
Transmission via insects or animals
Vector-borne
Pathway to which an agent enters a host body through orifices, membranes, or breaks in the skin
Entry Pathway
T or F: Usually, the exit pathway is not the same as the entry pathway
False (usually the same)
Someone prone to infection due to decreased ability to resist them (immunocompromised)
Susceptible Host
An effective way to prevent the spread of infection using soap and water
Hand Hygiene
“Sepsis” means what?
Microbial
T or F: One should bring the blood collection trays inside the nursery when doing these procedures
False (leave them outside the nursery/ICU)
This isolation procedure is done if you were exposed to someone carrying a transmissible disease
Quarantine
This isolation procedure is done if you are the one who’s sick and carrying a transmissible disease
Isolate
This isolation procedure is done for patients who are highly susceptible to infections (separating the immunocompromised)
Protective/Reverse Isolation
Type of microorganisms in human blood that are infectious and can cause disease
Blood-borne pathogens
T or F: Hepatitis B can survive for a week on objects
True
T or F: Hepatitis B’s mode of transmission is airborne
False (needle sticks and sexual contact)
Ability of a microbe to survive on surfaces for a long period of time
Viability
Degree of a microbe to cause disease
Virulence
T or F: HIV is more viable and more virulent than Hepatitis B
False (Hepatitis B is more viable and more virulent than HIV)
T or F: Disinfectant ratio of bleach solution should be 1:10
True (sodium hypochlorite)
Any material that could be harmful to one’s health
Biohazard
Safe handling of biological substances that pose a risk to health; prevents and protects clinical laboratories from harmful incidents caused by hazardous specimens
Biosafety
Protecting the organism from people that plan to steal or manipulate the specimen
Biosecurity
Permucosal transmission refers to transferring diseases through?
Mucous membranes of the mouth, nose, and eyes
Percutaneous transmission refers to transferring diseases through?
Intact skin via needle sticks and sharp objects
What are the 4 components of the fire tetrahedron?
Heat, fuel, oxygen, and a chemical reaction
T or F: Fire can be extinguished even if you remove just 1 element from the tetrahedron
True
Class of fire caused by ordinary combustible materials
Class A
Class A fires can be extinguished using what types of extinguishers?
A (Water), AB (Foam) or ABC (Dry Chemical)
Class of fire caused by flammable liquids and vapors (paint, oil, grease, gasoline)
Class B
Class B fires can be extinguished using what types of extinguishers?
AB (Foam), ABC (Dry Chemical), or BC (Dry Chemical)
Class of fire caused by electrical equipment
Class C
Class C fires can be extinguished using what types of extinguishers?
CO2-containing, ABC and BC (dry chemicals)
T or F: You can use foam in extinguishing Class C fires
False (NEVER use foam for electrical fires)
Class of fire caused by combustible chemical/reactive metals
Class D
Class C fires can be extinguished using what types of extinguisher?
D (Dry Powder)
Class of fire caused by cooking oil or grease fats
Class K
Class K fires can be extinguished using what types of extinguisher?
K (potassium-based alkaline liquid)
What does PASS mean for using fire extinguishers?
Pull pin, Aim nozzle, Squeeze trigger, and Sweep nozzle
What does RACE stand for in emergency fires?
Rescue people in danger, Activate fire alarms, Close all doors, and Extinguish the fire
T or F: You can pour water on acid
False
Injury characterized by abnormal or profuse bleeding
External Hemorrhage
Refers to insufficient return of blood to the heart which results to a lack of oxygen supply to all organs and tissue
Shock
Emergency procedure performed when the heart stops beating
Cardiopulmonary Resuscitation
How many inches should each push be when performing CPR?
2 inches
What is the ratio of compressions to rescue breaths?
30:2 respectively
