After careful inspection, the medical assistant finds soiled diapers in the biohazardous containers of both rooms. How would you handle this situation? ANSWER: The first priority is to remove the source of odor, then to decontaminate the area. It may also help to designate a separate location in the office for soiled diapers so that parents will know how to dispose of them. Many pediatrician offices have a system in place to prevent such odors in treatment room areas.Apply Your KnowledgeGood Job!35-*Room Temperature, Lighting, and VentilationMaintain examination room temperature at about 72°FEliminate drafts from windows and doors35-*Room Temperature, Lighting, and Ventilation (cont.)Good lighting neededAccurate diagnosesPerform medical proceduresRead orders and instructionsPrevent accidents 35-*Room Temperature, Lighting, and Ventilation (cont.)Examination area should smell clean and freshEliminate source of odorsIf opening windows, monitor room temperatureRoom deodorizer or spray35-*Apply Your KnowledgeANSWER: Good lighting is needed for making accurate diagnoses, performing medical procedures, reading orders and instructions, and preventing accidents.Why is it important to have good lighting in the examination room?Excellent!35-*Medical Instruments and SuppliesTasks to maintain instruments and suppliesOrder and stock all needed suppliesSanitize, disinfect, and/or sterilize instruments as neededInstruments and supplies should be placed within easy reach for the physician35-*InstrumentPurposeAnoscopeUsed to open the anus for examinationExamination lightProvides additional lightingLaryngeal mirrorReflects inside of mouth and throatNasal speculumUsed to enlarge the opening of the noseOphthalmoscopeUsed to examine the inner eye surfacesInstruments for a General Physical Exam35-*InstrumentPurposeOtoscopeUsed to examine the inner earPenlightSmall flashlight used to view a small areaReflex hammerUsed to check patient’s reflexesSphygmomanometerUsed to measure blood pressure StethoscopeUsed to listen to body soundsInstruments for a General Physical Exam (cont.)35-*InstrumentPurposeTape measureUsed to measure size or development of an areaThermometerUsed to measure body temperatureTuning forkUsed to test patients’ hearingVaginal speculumUsed to enlarge the vagina for specimens from cervix and vaginaInstruments for a General Physical Exam (cont.)35-*Instruments for a General Physical Exam (cont.)Inspecting and maintaining instrumentsBe sure instruments are in good working orderArranging instrumentsKeep instruments in same location, either: Mounted on wall Out on countertop Set on a clean towel or trayPreparing instrumentsSome instruments require warmingCleaning instrumentsPlace used instruments in a container and always handle carefully35-*Cervical scraperCotton ballsCotton-tipped applicatorsCurettesDisposable needlesDisposable syringesGauze, dressings, and bandagesGlass slidesSterile and clean glovesPaper tissuesOccult blood test slidesSpecimen containersTongue depressorsSupplies for a General Physical Exam 35-*Consumable SuppliesSupplies that are used upFixative – chemical spray used for preserving a specimen Isopropyl alcoholLubricant – a water-soluble gelBe sure patients do not have access toPrescription blanksDrugsNeedles 35-*Medical Instruments and Supplies (cont.)Storing supplies in cabinets and drawersLabel so items can be easily locatedRoutinely straighten and clean Restocking suppliesReorder when the first half of a box, tube, or bottle has been used35-*stethoscopenasal speculumreflex hammerotoscopepenlightlaryngeal mirrorophthalmoscopetape measuresphygmomanometertuning forkanoscopeApply Your KnowledgeA medical assistant is preparing the treatment room for a local ENT specialist.

Instruments and equipment in the room should be easily accessible. 35-*In Summary (cont.)35.3 Steps involved in preventing the spread of infection in the examination room include covering the examination table with a paper cover and changing the cover between each patient. It is also important to disinfect all surfaces that come in contact with blood or body fluids after each patient, and at the beginning and end of the day.35-*In Summary (cont.)35.4 Examination room surfaces should be disinfected after an examination or treatment during which surfaces have become visibly contaminated, immediately following accidental blood or body fluid spills or splatter, and at the end of the medical assistant’s work shift.35.5 It is important that patients feel comfortable in the examination room. A room that is comfortably warm, well lit, and properly ventilated will help the patient feel comfortable during the examination. 35-*In Summary (cont.)35.6 A variety of instruments and supplies are used in a general physical examination. To ensure that the examination room always has the necessary instruments and supplies, the medical assistant should order and stock all supplies needed for examinations and treatment procedures, keep the instruments sanitized, disinfected, or sterilized and in working order, and place all instruments and supplies where the doctor can easily reach them.35-*In Summary (cont.)35.7 To eliminate hazards to physical safety in the examination room, the medical assistant should be alert for any physical hazards in the area, including spills, dropped objects, open cabinet doors, damaged furniture, or improperly secured cords and cables. 35-*Safety is something that happens between your ears, not something you hold in your hands. ~ Jeff CooperEnd of Chapter 35
