FUNDAMENTALS FINAL EXAM Flashcards
standard precautions
Prevent and control transmission of diseases that can be acquired by contact it with blood, body fluids, non-intact skin, and mucous membranes.
isolation precautions
Protect patients, their families, other visitors, and healthcare workers from spreading germs across a healthcare setting.
Contact isolation
Direct and indirect contact with patients and environment.
Droplet isolation
Diseases that are transmitted by large droplets expelled into the air.
airborne isolation
transmitted by smaller droplets. 3 ft, and can remain in air for a longer amount of time.
Gowns
prevent soiling clothes (infected material, blood or bodily fluid)
Masks
Respiratory protections (blood, bodily fluids) airborne.
Protective eyewear
when performing procedures that splash or splatter (large abdomen wound or insertion)
Gloves
help prevent transmission of pathogens by indirect or direct contact.
What is the chain of infection
- Infectious agent or pathogen.
- Reservoir
- Portal of exit
- Mode of transmission
- Portal of entry
- Host
Infectious agent or pathogen
bacteria, viruses, fungi, and protozoa.
Reservoir
places in the environment where the pathogen lives. (people, animals, insects, medical equipment).
Break the chain by sterilizing, cleaning, pest control.
Portal of exit
after microorganisms grow they find the portal of exit, so they are able to enter another host and cause disease (mucus, gi tract) You can break this chain by washing your hands, personal protective equipment, control of splatter, and waste disposal.
Mode of transmission
direct, indirect, droplet, airborne, vehicles, vector. You can break the chain by hand hygiene, PPE, food safety, isolation.
Portal of entry
enter the body in the same route as exiting (hand hygiene, PPE, personal hygiene, first aid)
Host
susceptible host to spread disease (immunizations, treatment of underlying disease, health insurance, patient education)
Risk factors for developing infections
Age, nutritional status, stress, and disease process.
Medical asepsis
(clean technique) reduces number of organisms present and prevent transfer
Surgical asepsis
(sterile technique) prevents contamination of an open wound. Maintains sterile field for surgery.
Community acquired disease
diseases developed outside the hospital. Patient acquires disease within 2 days of admission.
Hospital acquired disease
Diseases developed from the hospital. Lower respiratory tract infections. Patient acquires disease two day after discharge.
Localized infections
wound infection.
symptoms include: pain, tenderness, warmth, redness.
Systemic infections
affects entire body. Can become fatal if undetected and untreated.
Fowler Position.
45-60 degrees, patient head slightly elevated.
