listening for sounds within the body and is usually performed through a stethoscope.

Rale

Sims' Position

a test based on the speed at which the red blood cells seperate from the plasma and settle to the bottom of the container. An elevated sed rate indicates the presence of inflammation in the body.

Hematocrit

describes the percentage, by volume, of a blood sample occupied by red cells. This test is used to diagnose abnormal states of hydration, polycythemia, and anemia.

Red Blood Cell Count

a determination of the number of erythrocytes in the blood. A depressed count can indicate anemia or a hemorrhage lating more than 24 hours.

Total Hemoglobin Test

usually part of a complete blood count. Elevated Hg levels indicate a higher than normal hemoglobin concentration in the plasma due to polycythemia or dehydration. Low Hg levels indicates lower than normal hemoglobin concentration due to anemia, recent hemorrhage, or fluid retention.

measures the amount of nitrogen in the blood due to waste product urea. This test is performed to obtain an indication of kidney function.

Specific Gravity

reflects the amount of wastes, minerals, and solids that are present in urine.

has a sweet, fruity odor, is found in small quantities in normal urine and in larger amounts in the urine of a diabetic.

Albuminuria

the presence of the protein albumin in the urine and is a sign of impaired kidney function.

Radiopaque Contrast Medium

the substance does not allow x-rays to pass through and appears white or light gray on the resulting film.

Radiolucent Contrast Medium

the substance such as air or nitrogen gas does allow x-rays to pass through and appears black or dark gray on the resulting film.

Anteroposterior Projection

the patient positioned with the back parallel to the film. The x-ray beam travels from anterior to posterior.

Posteroanterior Projection

the patient positioned facing the film and parellel to it. The x-ray beam travels through the body from posterior to anterior.

Lateral Projection

the patient positioned at right angles to the film. This veiw is named for the side of the body nearest the film.

Oblique Projection

the patient positioned so the body is slanted sideways to the film. This is halfway between a parallel and a right angle position.

Magnetic Resonance Imaging (MRI)

uses a combination of radio waves and a strong magnetic field to create signals that are sent to a computer and converted into images of any plane through the body.

Magnetic Resonance Anigography (MRA)

combines MRI with the use of a contrast medium to located problems within blood vessels throughout the body.

Nuclear Medicine

radioactive substances known as radiopharmaceuticals are administered for either diagnostic or treatment purposes.

Radiopharmaceuticals

are administered for either diagnositc or treatment purposes.

Positron Emission Tomography (PET imaging)

combines tomography with radionuclide tracers to produce enhanced images of selected body organs or areas.

Adverse Drug Reaction

an undesirable reaction that accompanies the principal response for which the drug was taken.

Idiosyncratic Reaction

an unexpected reaction to a drug that is peculiar to the individual.

Palliative

a substance that eases the pain or severity of the symptoms of a disease, but does not cure it.

Paradoxical Reaction

the result of medical treatment that yields the exact opposite of normally expected results.

Placebo
