Infection Control/Wound Care. CH 14,16,22,26

Chain of Infection (6) "Links" (1) infectious agent, (2) reservoir, (3) portal of exit, (4) mode of transmission, (5) portal of entry, (6) susceptible host
Direct Contact Person to person
Disinfectant A cleaning agent that removes most pathogens
HAI Heath-care Associated Infection
Indirect Contact Person- to contaminated object- to person
Localized Infection Affecting one area of the body. Ex: bacterial pnemonia
Medical Asepsis Practices performed to prevent the spread of infection. Ex: hand hygiene, standard precautions, clean enviorment,etc.
Microoranisms Minuscule, living organisms
Normal Flora and Fauna Microorganisms found naturally I the human body, used to fight pathogens and digest food.
Pathogens Microorganisms that cause infection/illness.
Primary Infection Infection caused by one pathogen
Secondary Infection Infection caused by a second pathogen
Standard Precautions Safety measures to prevent the transmission of *all* pathogens
Systemic Infection Infection spread through bloodstream
Transmission-based Precautions Safety measures to prevent the transmission of *known* pathogens
Vectors Organisms carrying pathogens.
Contractures Shortening and tightening of the muscles due to lack of use
Dorsiflexion Ankle at 90°, toes pointing to ceiling (in supine position)
Footdrop Permanent plantar flexion caused by improper dorsiflexion.
Fowler's Position Semi-sitting position with varied degree of head elevation
Lateral Position Laying on side, with pillows behind back and between knees
Logroll Turning the body as one unit, 3 people are required to position Pt properly at head, waist, and legs
Orthopneic Position Sitting upright, either with bed at 90° or sitting on side of bed with feet flat on the floor
Orthostatic Hypotension Low blood pressure due to rapid position changes
Plantar Flexion Foot pointed in a downward position
Position of Function Placing the extremities in alignment to maintain the potential for use and movement
Prone Position Lying on stomach with head to the side
Semi-fowler's Position Reclined sitting position with head at 45°
Shearing Skin layer is pulled across muscle and bone while the skin slides over another surface (sheet) in opposite direction.
Sims' Position Also called supine with arms at sides
Supine Position Laying on back
Syncope Fainting
Transfer Move Pt from one place to another
Trochanter Roll Rolled towel or cylindrical device placed snugly against lateral aspect of Pt thigh to prevent leg from rotating outward.
Autoclaving Method of sterilization, uses steam under pressure, with heat ranging from 250° to 270°
Boiling Method of sterilization, boils instruments and supplies in water for 10 mins - DOES NOT KILL SPORES
Chemical Disinfection Method of sterilization, used to kill pathogens on equipment and supplies that cannot be heated. Ex: codes used to sterilize rubber-based catheters.
Circulating Nurse RN that assists in the OR by obtaining needed equipment and supplies.
Contamination Potential presence of a pathogen on a sterile field or sterile object, due to contact with an unsterile surface.
Disinfected Killing pathogens with cleaning solutions
Gaseous Disinfection Method of Sterilization, kills pathogens on supplies and equipment that are sensitive to heat or must remain dry
Ionizing Radiation Method of Sterilization, kills pathogens on sutures, some plastics, and biological materials that can't be boiled or autoclaved
Scrub Nurse Assists the physician throughout the surgery by handing instruments, holding retractors, and preforming other tasks that require sterile garb.
Sterile Conscience Always being aware of potential or certain contamination of the sterile field or sterile objects
Sterile Field An area free of all microorganisms where sterile items may be placed until they are ready for use.
Sterile Technique Method used to prevent contamination during invasive procedures or within a body cavity
Sterilized Using steam, gas, or radiation to kill all pathogens and their spores
Surgical Asepsis Or sterile technique
Abrasion Superficial open wound
Débridement Surgical removal of dead tissue
Dehiscence Partial or complete seperation of the outer layers of a wound. Rare but serious complication of wound healing.
Erythema Redness
Eschar Hard, dry, dead tissue - has a leathery apperance
Evisceration Protrusion of ABD contents though an open ABD wound
Granulation Tissue New, extremely fragile tissue that forms during the reconstruction phase of healing
Hemorrhage Bleed profusely
Ischemia When tissues and capillaries are compressed, resulting in reduced blood flow to the area
Laceration Open wound made by the accidental cutting or tearing of tissue
MRSA Methicillin-resistant Strephylococcus aureus
Necrotic Dead tissue
Pressure Ulcer Wound resulting from pressure and friction
Purulent Containing pus drainage
Sanguineous Drainage that looks like blood. Seen first (in typical healing)
Serosanguineous Drainage looks pink. Seen second (in typical healing)
Serous Drainage becomes clear to slightly yellow. Seen last (in typical wound healing)
Sinus Tract A tunneling wound that has a narrow opening or passageway underneath the skin that can extend in any direction through soft tissue and results in dead space with potential for abscess formation
HAIs once called __________ Nosocomial infections
