identification of a disease or condition by scientific evaluation of physical signs, symptoms, history, tests, and procedures.
predicted outcome of a disease
having a short and relatively severe course
opposite is chronic
meaning that the disease exists over a long time.
are objective, or definitive, evidence of an illness or disordered function that are perceived by an examiner, such as fever, a rash, or evidence established by radiologic or laboratory testing.
are subjective evidence as perceived by the patient , such as pain.
a small sample or part taken from the body to represent the nature of the whole.
rhythmic expansion of an artery that occurs as the heart beats
60 to 100 beats per minute
a normal pulse rate in a resting state
refers either to the exchange of oxygen and carbon dioxide within the body, or to breathing.
an electronic instrument that measures body temperature by pacing the probe at the opening of the external ear.
the pressure exerted by the circulating volume of blood on the walls of the arteries and veins and on the chambers of the heart.
the examiner uses the eyes and ears to observe and listen to the patient. Inspection could reveal superficial abnormalities, such as a rash.
the examiner feels the texture, size, consistency, and location of certain body parts with the hands.
the examiner taps the body with the fingertips or fist to evaluate the size, borders, and consistency of internal organs and to determine the amount of fluid in a body cavity.
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 frequently with a stethoscope.
an instrument consisting of two earpieces connected by flexible tubing, the diaphragm is placed against the patient's skin to hear sounds within the body.
instrument for recording
instrument used in a visual examination
instrument used to measure
process of measuring
process of recording
visual examination wth a lighted instrument
an illuminated instrument for the visualization of the interior of a body cavity or organ.
the visual inspection of the body by means of an endoscope
means pertaining to endoscopy or performed using an endoscope
is a hollow flexible tube that can be inserted into a cavity of the body to withdraw or instill fluids, perform tests, or visualize a vessel or cavity.
the introduction of a catheter
is also used to mean a hollow flexible tube that is inserted into vessels or cavities.
requires entry of a body cavity
the image data are digitized and immediately displayed on a monitor or recorded on film.
emitting or reflecting light
substances that do not permit the passage of x-rays
describes substances that readily permit the passage of x-rays
sonography also called
uses ionizing radiation to produce a detailed image of a crosss section of tissue, similar to what one would see if the body or body part were actually cut into sections.
record produced by a CT scan
Magnetic resonance imaging
creates images of internal structures based on the magnetic properties of chemical elements within the body and uses a powerful magnetic field and radiowave pulses rather than ionizing radiation such as x-ray
sonography is the process of imaging deep structures of the body by sending and receiving high frequency sound waves that are reflected back as echoes from tissue interfaces.
record produced in sonography
visual examination of an internal organ using a fluoroscope. This technique offers continuous imaging of the motion of internal structures and immediate serial images, such as during surgery.
Positron emission tomography (PET)
combines tomography and radioactive substances to produce enhanced images of selected body structures, especially the heart, blood vessels, and the brain.
the treatment of tumors using radiation to destroy cancer cells.
