front 1 MAss and atomic particles consists of? | back 1 atoms, free electrons |
front 2 what are Insulators? | back 2 materials that inhibit the flow of electrons; rubber and plastic that wrap conductors |
front 3 What are conductors? | back 3 silver, copper, aluminum, zinc, brass, iron, saltwater, carbon and some acids |
front 4 wall outlet are usually? | back 4 110 volts |
front 5 how many volts are for laser units? | back 5 220 volts |
front 6 first prong means? | back 6 positive, active |
front 7 second prong means? | back 7 negative, neutral |
front 8 third prong means? | back 8 ground |
front 9 ESU unit monopolar characteristics? | back 9 cuts and coagulates requires grounding pad |
front 10 ESU unit Bipolar characteristics? | back 10 only used for coagulating not cutting, does not need a grounding pad, forces, and cord may be reusable. |
front 11 What is the vibration rate per second for ultrasonic energy? | back 11 55,000 |
front 12 what is ultrasonic energy? | back 12 the harmonic scalpel uses ultrasonic energy to cut and coagulate tissue. |
front 13 what is CUSA? | back 13 high-frequency sound waves that create imploding bubbles to fragment and emulsify tumors and leave blood vessels intact. |
front 14 What are Lasers? | back 14 light amplification by the stimulated emission of radiation. The shorter the wavelength the higher the energy and more dangerous. |
front 15 what is Joules? | back 15 a measurement of laser pulse energy based on a 1 second time beam is activiated. |
front 16 What is the most frequently used lasers? | back 16 CO2 lasers |
front 17 Most instruments are mostly made up of? | back 17 stainless steel |
front 18 stainless steel is a combination of? | back 18 carbon, chromium, iron, |
front 19 chromium increases resistance to | back 19 corrosion |
front 20 Titanium is? | back 20 stronger and lighter in weight than stainless steel, has a blue finish of titanium oxide. |
front 21 highly polished bright does what? | back 21 increases resistance to corrosion but has a tendency to reflect lights. |
front 22 satin (dull) finish does what? | back 22 less reflective and reduces glare |
front 23 ebonized (black chromium) is? | back 23 non-reflective and virtually eliminates glare. |
front 24 ebonized (black chromium) is recommended for? | back 24 procedures involving a laser because it prevents deflection of the laser beam. |
front 25 blades 10, 11, 12, 15 fit what number handles? | back 25 3,7, and 9 |
front 26 blades 20-25 fit what knife handle? | back 26 number 4 knife handle |
front 27 Tissue scissors should never be use to? | back 27 cut anything other than tissue because it will dull the blades |
