Week 8 Terms Flashcards
Computed tomography (CT)
Imaging technique that obtains cross-sectional X-ray views
Contrast medium
Radiopaque fluid used in radiation studies to determine shape and density of anatomy
Doppler studies
Technique that uses ultrasonic waves to measure blood flow in a vessel
Magnetic resonance imaging (MRI)
Diagnostic technique that uses radio frequency signals and magnetic energy to produce images
Fluoroscopy
Radiological technique that provides real-time images of an anatomical region
Malignant
Used to characterize tissue that shows disorganized, uncontrolled growth
Palpating
Assessing a part of the body by feeling outline, density, movement, or other attributes
Positron emission tomography (PET)
Type of medical imaging that measures specific metabolic activity in the target time
Airborne transmission precautions
Precautions that prevent airborne transfer of ds organism in the environment
Blood-borne pathogens
Harmful microbes that may present in and transmit through human blood and body fluids
Chemical risk factors
Hazards related to primarily to liquid, gas, and solid chemicals in the preoperative environment
Electrocution
Severe burns, cardiac disturbances, or death as a result of electrical current discharged into the body
Electrosurgical unit (ESU)
Medical device commonly used in sx to coagulate blood vessels and cut tissues
Eschar
Burned tissue fragments that accumulate on the ESU tip; can cause sparking and become source of ignition
Flammable
Capable of burning
Grounding
Path for electrical current to flow unimpeded through material and disperse back to the source or in the body
Hypersensitivity
Cell-mediated immune response to a substance in the body
Impedance (resistance)
Ability of a substance to stop or alter the flow of electrons through a conductive material
Latex
Naturally occurring sap obtained from rubber trees used to manufacture medical devices, supplies, and pt care items
Neutral zone (no-hands) technique
Method of transferring sharp instruments on the surgical field w/o hand-to-hand contact
Occupational exposure
Exposure to hazards in the workplace
Oxidizers
Agents or substance capable of supporting fire
Oxygen enriched atmosphere (OEA)
Environment that contains a high percentage of oxygen; high risk of fire
Personal protective equipment (PPE)
Recommended procedures to help prevent the development of blood-borne ds after an exposure incident
