surg 100 ch 5 quiz
| Question | Answer |
|---|---|
| transfers concentrated electrical current into another medium | active electrode |
| electrical current which flows from ESU to active electrode + current will not flow to other parts of the patients body | bipolar |
| new term that replaces dispersive electrode; also called a grounding pad | dispersive pad |
| electronic medical record providing a secure record of patients care | electronic health record |
| a digital version of the patients chart that contains their medical + treatment history | electronic medical record |
| the application of AC through tissue to coagulate or cut tissue | electrosurgery |
| mechanical device that produces an electric current that is converted into thermal energy for the purpose of cutting or coagulating tissue | electrosurgical unit (ESU) |
| federal law implemented to protect a patients personal health information | (HIPPA) |
| electrical current which flows from the ESU through the return electrode to complete a electrical cautery circuit | monopolar |
| a list of a surgeons preferred supplies + equipment for a specific procedure | preference card |
| any information about a patients health status linked to a specific individual | protected health information (PHI) |
| safety and handling information regarding the chemicals and solutions used in the health care facility | safety data sheets (SDS) |
| the _ is the brain of the computer that processes instructions | CPU - central processing unit |
| the start up process that loads the operating system is called | booting |
| keyboards, monitors, and barcode scanners are all examples of | hardware |
| electronic preference cards and instrument tracking systems are examples of | software |
| a _ is the patients chart kept within one practice or facility | EMR - electronic medical record |
| a _ is shared securely with all of the patients providers and the patient | EHR- electronic health record |
| the _ requires hospitals to keep electronic patient records | CMS- centers for Medicare and Medicaid services |
| any patient health information that can identify the patient is called | PHI- protected health information |
| read by an optical laser, scans one item at a time, and the scanner must see the code | Barcode |
| read by radio frequency waves, reads many tags at once with no line of sight, each tag holds a microchip that stores information | RFID |
| what's the difference between open and available | open- opened onto the sterile field during setup because you will use it available- kept in the room, unopened, until the surgeon asks for it |
| what are the 6 sections a CST uses the most on a SDS | identification, hazards, first aid, spills, handling and storage, and PPE |
| what conductor is used the most because it is inexpensive | copper wire |
| how does current travel through a chain of conductors | copper wire in the ESU cord carries current from generator to the pencil, then the metal ESU tip, carries current into the tissue, then current flows through the body to the dispersive pad |
| what is a poor conductor and blocks electricity | insulator |
| anything that makes it hard for current to flow | resistance |
| if it is too dry in the OR what forms | sparks |
| what is the humidity range in the OR supposed to be at | 20-60% |
| tiny bits inside every atom | electrons |
| electrons moving along a wire | current |
| how do electrons and current move | from the end with too many (negative) to the end with too few (positive) |
| a closed loop that current travels around | circuit |
| what kind of volts does most OR equipment have | 110 volts |
| mobile x-rays and some lasers need how many volts | 220 volts |
| three prongs | positive, negative, ground |
| the round ground prong is the | safety prong |
| one direction only, negative to positive, made by batteries, stops when the switch is open; OR example : battery powered drills + saws | direct current > |
| electrons go forward then back, over and over, one trip forward and back, OR example : anything plugged into the wall outlet | alternating current > < |
| wall power is | 60 cycles per second |
| ESU is | over 100,000 per second |
| what is the difference between electrosurgery and electrocautery | electrosurgery- current goes from the pencil, through the patient, and back to the machine electrocautery- current stays in the tool +NEVER goes into the patient |
| a system that watches the electricity in that OR | IPS- isolated power systems |
| what are the steps when a isolated power alarm goes off | 1. light turns red, alarm sound 2. carefully unplug the last item plugged in ; not random equip. 3. light turns green, alarm stops; that item was the problem 4. take it out of service; biomed checks it before reuse |
