Show Answers:

  1. the identification of a disease or condition by a scientific evaluation of physical signs, symptoms, history, test and procedures
  2. "WNL" is an abbreviation for what?
    within normal limits
  3. the predicted outcome of a disease
  4. having a short and relatively severe course
  5. the disease exists over a long period of time
  6. objective or definitive, evidence of an illness or diordered function that are perceived by an examiner such as fever, a rash, or evidence established by radiologic or lab testing
  7. subjective evidence as perceived by the patient such as pain
  8. rhythmic expansion of an artery that occurs as the heart beat, may be felt with a finger
  9. the number of pulse beats per minute
    pulse rate
  10. the number of breaths per minute... rise and fall of the patient's chest is observed while counting the number of breaths and noting the ease with which breathing is accomplished
    respiration rate
  11. instruments used to measure temperature
  12. has a specifically designed probe tip at the external opening of the ear canal
    tympanic thermometer
  13. the pressure exerted by the circulating volume of blood on the walls of the arteries and veins and the chambers of the heart
    blood pressure
  14. higher reading (normal reading is 120) due to ventricular contraction
    systolic pressure
  15. lower reading (normal reading is 80), occurs when the ventricles relax
    diastolic pressure
  16. what are the 4 impt technizes useful for physical examination?
    • 1. inspection: the examiner uses the eyes and ears to observe and listen to the patient
    • 2. palpation: the examiner feels the texture, size, consistency, and location of certain body parts with the hands
    • 3. percussion: the examiner taps the body with the fingertips or fist to evaluate the size, border and consistency of internal organs and to determine the amount of fluid in a body cavity
    • 4. auscultation: the examiner listens for sounds within the body to evaluate the heart, blood vessels, lungs, intestines or other organs, or to detect the fetal heart sound (performed most commonly with a stethoscope)
  17. was the predominant means of diagnostic imaging for many years, with x-rays providing fil images of internal structures
  18. substances that don't permit the passage of x-rays
  19. describes substances that readily permit the passage of x-rays
  20. uses ionizing radiation to produce a detailed image of a cross section of tissue, similar to what i would see if the body or body part were actually cut into sections
    • computed tomography (CT)
    • formerly known as computed axial tomography (CAT)
  21. image produced from a computed tomography (CT)
  22. non-invasive technique for visualizing internal structures that creates images based on the magnetic properties of chemical elements with the body and uses a powerful magnetic field and radiowave pulses rather than ionizing radiation such as x-rays; produces superior soft-tissue resolution for distinguishing adjacent structures
    magnetic resonance imaging (MRI)
  23. the process of imaging deep structure sof the body by sending and receiving high-frequency sound waves tha tare reflected back as echoes from tissue interfaces; very safe because non invasive and doesn't use ionizing radiation; many medical applications including imaging of the fetus
  24. method of viewing the x-ray image directly in real time so that motion can be seen and radiography provides a permanent record of the image at a particular point in time
  25. administered to a patient orally, into a vein or by having the patient breathe the material in vapor form; for nuclear scans
    radio pharmaceuticals
  26. combines tomography and radioactive substances to produce enhanced images of selected body structures, especially the heart, blood vessels and the brain; radioactive materials using this method are very short lived so patients are exposed to very small amounts of radiation
    positron emission tomography (PET)
  27. the treatment of tumors using radiation to destroy cancer cells; may be applied by directing a beam of radiation toward the tumor with a machine that delivers radiation doses many times higher in intensity than those that are used for diagnosis or the radiation may be introduced throguh the bloodstream or surgically implanted
    • radiotherapy
    • aka radiation oncology
  28. treatment of disease using chemical agents
  29. tom/o
    to cut
