  1. Plethysmography (venous)
  2. Rhythm Strip
  3. B-scan
  4. Endoscope
  5. Caloric Study
  1. a An image made up of a series of dots, each indicating a single ultrasonic echo. The position of a dot corresponds to the time elapsed, and the brightness of a dot corresponds to the strength of the echo.
  2. b A test performed to evaluate the function of cranial nerve VIII. It also can indicate disease in the temporal portion of the cerebrum.
  3. c Measures changes in the volume of an extremity; usually performed on a leg to exclude DVT (deep vein thrombosis)
  4. d A cardiac study that demonstrates the waveform produced by electrical impulses from the electrocardiogram
  5. e A tubular instrument (rigid or flexible) with a light source and a viewing lens for observation that can be inserted through a body orifice or through a small incision

5 Multiple choice questions

  1. Image obtained with M-mode echocardiography shows the motion (M) of the heart over time. 2-D M-mode would be a two-dimensional study
  2. Usually performed to rule out occlusive disease of the lower extremities, or may identify arteriosclerotic disease in the upper extremity
  3. An enhanced form of Doppler echocardiography; different colors are used to designate the direction of blood flow
  4. A portable device that records the heart's electrical activity and produces a continuous EKG tracing over a specified period
  5. The transmission of data electronically to a distant location

5 True/False questions

  1. Cardiac MonitorA portable device that records the heart's electrical activity and produces a continuous EKG tracing over a specified period

          

  2. EchoThe reflection of an ultrasound wave back to the transducer from a structure in the plane of the sound beam

          

  3. Capillary Blood Gases (CPG)A diagnostic study performed primarily on infants. Blood is obtained from the infant's capillary arterial vessel, usually from the heel

          

  4. Arterial Blood Gases (ABG)A diagnostic study performed primarily on infants. Blood is obtained from the infant's capillary arterial vessel, usually from the heel

          

  5. Electroencephalogram (EEG)A graphic recording of the electrical impulses that the heart generates during the cardiac cycle
