chapter 4 Flashcards
WNL
Within normal limits
prognosis
The predicted outcome of the disease
acute
Short and severe
chronic
Exists over a long time
signs
Objective (perceived by examiner) and definitive evidence of an illness or disordered function established by radiographic or laboratory testing
Symptoms
Subjective evidence that is perceived by the patient such as pain
specimen
A small sample or part taken from the body to represent the nature as a whole
pulse
Rhythmic expansion of an artery as the heart beats
respiration
Either the exchange of oxygen and carbon dioxide within the body or breathing
Tympanic thermometer
Thermometer that goes in ear
Blood pressure
The pressure exerted by the circulating volume of blood on the walls of the arteries and veins and on the chambers of the heart
Normal blood pressure
120/80
Systolic pressure
Higher reading
Diastolic pressure
lower reading
inspection
Using eyes and ears to observe and listen to the patient ex: seeing a rash
palpation
the examiner feels the texture, size, consistency, and location of certain body parts with the hands ex: felling an enlarged liver
percussion
The examiner taps the body with fingertips or fist to evaluate the size, boarders, and consistency of internal organs and to determine the amount of body fluid in the cavity
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
stethoscope
Instrument consisting of two earpieces connected by flexible tubing that is used to hear sounds within the patient’s body
endoscope
An illuminated instrument used for the visualization of the inside of a body cavity
catheter
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
Invasive procedure
Requires entry of a body cavity or interruption of normal body function

radiopaque
Substances that do not permit the passage of x-rays
radiolucent

sonography
Aka ultrasound: sends high frequency waves that are reflected back as echoes

PET
Positron emission tomography
sonography
Imaging of internal structures by measuring and recording sound waves
Nuclear medicine
Placing radioactive materials into body organs and using computerized scanners
Computed tomography
Producing detailed images of cross sections of tissues as if cuts had been made
Contrast imaging
Using radiopaque materials to make internal organs or vessels visible
Magnetic resonance imaging
Visualizing internal structures based on magnetic properties of chemical elements
