45 Laboratory and Diagnostic Examinations Radiographic studiesMyelogramElectromyographyBone scanBone mineral densityX-rayEndoscopic examinationArthroscopy
46 Radiographic StudiesReveals presence of fluid in joint, irregularity of joint, spur formation, and changes in size or contour of the jointVisualizes fractures, length, tumors, and cavities of bonePregnant women should not have an x-ray, unless it is absolutely necessary, to prevent potential damage to the fetus
47 Laminography/planography or body section roentgenography Radiographic StudiesLaminography/planography or body section roentgenographyLocates small cavities, foreign bodies andlesions that are overshadowed by opaquestructures
48 Scanography Radiographic Studies Uses a series of parallel beams that eliminate sizedistortion when producing a radiograph of internal body organsAllows accurate measurement of the lengthof the bone
49 Used to determine the presence of herniated discs or tumors MyelogramUsed to determine the presence of herniated discs or tumors
50 MyelogramAn x-ray study in which dye is injected into the spinal fluid. (The spinal cord is not visible on a normal x-ray.)Injection of this dye outlines the spinal cord, and makes it visible on the x-ray.
51 MyelogramThe injection of dye may be done in the cervical or lumbar areaBefore the dye is injected, a sample of spinal fluid is collected from the patient and is submitted to the laboratory for analysis.
53 MyelogramWater based dye is used most often because the body will reabsorb it and will be excreted in the urineOil-based dye will be removed because it may cause irritation within the subarachnoid space
54 MyelogramHeadache is most common after a myelogram but seizure, infection, numbness, or paralysis may occur
55 Myelogram Prior to procedure: Post-procedure Informed consent Provide hydration 12h before testAssess for allergiesPremedicate as orderedPost-procedureVS/neuro checks as orderedIf water based dye used, HOB up degrees for 8 hIf oil based dye used, flat for 6-8 hIf air used, head lower than trunkForce fluids, monitor I&O
56 Electromyography (EMG) Measures electrical potential associated with skeletal muscle contractionsNeedles inserted into muscle; electrical activity traced on recording paperInformed consentNeedle insertion uncomfortableNo stimulants/sedatvies 24h prior to procedureSlight bruising at insertion sites
57 ElectromyographyYour doctor has ordered this test to help determine the cause of your pain.This test is specifically performed to identify if abnormal nerve function is present.The small electric pulses cause a mild tingling feeling.
58 EMG are using a transcutaneous electrical nerve stimulator (TENS) unit Inform your physician if you:are using a transcutaneous electrical nerve stimulator (TENS) unitare taking blood thinnershave hemophiliahave a cardiac pacemakerDo not apply lotion to the arms or legs on the day of the test.
59 Nuclear ScanningUses scanners or camera detectors that record images on radiographic filmDoses of radioactive isotopes are low; no need for precautionary measures as required for radium therapy
60 Nursing Interventions Obtain written consentInforming patient that radioactive isotopes will not affect family/visitorsFollow instructions as outlined by the nuclear medicine department as to special preparation for the specific scans
61 Magnetic Resonance Imaging Used to detect pathological conditions:CerebrumSpinal CordCurrently used to detect herniated nucleus pulposes (herniated disc)
62 MRIInvolves use ofMagnetism and Radio Waves to make images of cross sections of the bodyVery detailed pictures of fluid-filled soft tissue and blood vessels
63 Nursing Considerations Patient preparationRemove any metalNo jewelry, clothing with metal fasteners, glasses, and hair clips
64 Nursing Considerations CANNOT HAVE MRI if patient has a metal prostheses:Heart valvesOrthopedic screwsCardiac pacemakers or defibrillators
65 Nursing Consideration Patient must be able to lie still for 45 to 60 minutesEnters the tunnel head first anxiety and/or claustrophobiaMay need sedativeRelaxation therapy can helpHowever: No use of relaxation techniques that require flexing and relaxing of muscles – Pt. HAS TO LIE MOTIONLESS!After test:Routine vital signsPretest activities can be resumed
66 Computed Axial Tomography CT Scan Views body sections from different anglesCT scanner produces a narrow x-ray beamProduces a three-dimensional picture of structures100 times more sensitive than x-rayShould not be used unnecessarily because of radiation exposureIodine contrast is sometimes usedUsed for the head and body
67 CT or CAT Scan Useful in locating Injuries to ligaments or tendonsTumors of soft tissueIdentifying fractures in difficult areasPerformed with or without contrast (iodine) dye
68 Patient Preparation Consent form Check Allergies to iodine and seafood (shellfish)NPO 3 to 4 hours before test if dye is used (dye can cause nausea/vomiting)Baseline vital signsVoidRemove jewelry and hairpinsLie still; may feel warm and slightly nauseated for a few minutes when dye is injected
69 Nursing Consideration After the test:Observe for delayed allergic reactionEncourage fluidsPretest diet and activity can usually be resumed
70 Bone ScanA bone scan is a nuclear scanning test that identifies new areas of bone growth or breakdown.It can be done to evaluate damage to the bones, detect cancer that has spread (metastasized) to the bones, and monitor conditions that can affect the bones (including infection and trauma).A bone scan can often detect a problem days to months earlier than a regular X-ray test.
72 Bone ScanFor a bone scan, a radioactive tracer substance is injected into a vein in the arm.The tracer then travels through the bloodstream and into the bones.A bone scan may be done on the entire body or just a part of it.
73 Bone ScanAreas that absorb little or no amount of tracer appear as dark or "cold" spots, which may indicate a lack of blood supply to the bone (bone infarction) or the presence of certain types of cancer.Areas of rapid bone growth or repair absorb increased amounts of the tracer and show up as bright or "hot" spots in the pictures. Hot spots may indicate the presence of a tumor, a fracture, or an infection.
74 Bone Scan Isotope excreted within 48h Hold fluids for 4 hrs. prior to Informed consent
75 Bone Mineral Density Lose some bone mass as we age Bones become thinner (osteopenia)Existing bone broken down faster than new bone is made bones lose Ca⁺ and other minerals become lighter, less dense, more porous weaker bones; ↑ risk for fx.
76 BMDWith further bone loss, osteopenia leads to osteoporosis . So the thicker your bones are, the longer it takes to get osteoporosis.Although osteoporosis can occur in men, it is most common in women older than age 65.
77 BMD Measures bone mass of spine, other bones and total body Minimal radiation exposureUsed to diagnose metabolic bone disease, monitor changes in bone density with treatment
78 Arthroscopy Provides endoscopic examination of various joints Cartilage abnormalities assessed, loose bodies removed, cartilage trimmedBiopsy may be performed
80 Arthroscopy Interventions: Instruct pt. to fast 8-12h prior to procedureInformed consentPain med as prescribed post procedureElastic wrap 2-4 days post procedureWalking without weight bearing permitted after sensation returns, limit activity for 1-4 daysElevate extremity, ice to minimize swelling
