BMET Course 104 Clinical Applications
QUESTIONS WITH 100% CORRECT
ANSWERS, GRADED A+
Aspirate - CORRECT ANSWER -To draw by suction
Catheter - CORRECT ANSWER -Tubular tip connected to a suction hose for
insertion into canals, passageways, or body cavities
Evacuate - CORRECT ANSWER -To remove the contents of a body cavity or
organ
Matter - CORRECT ANSWER -Any solid, liquid, or gas that has mass and
occupies space
Reed Valve - CORRECT ANSWER -type of check valve that restricts flow to a
single direction, opening and closing under changing pressure on each face
Yankauer - CORRECT ANSWER -A hand held suctioning tool made of metal or
firm plastic with tip consisting of a large opening surrounded by a bulbous head
Rotary-vane - CORRECT ANSWER -As rotation continues, the space between
the vanes expand creating a negative pressure that draws air through the input port applying suction to the patient circuit
Diaphragm - CORRECT ANSWER -As this is pulled back, a vacuum is
developed drawing air through the intake valve while pulling the discharge valve closed
Cylinder Piston - CORRECT ANSWER -Creates suction similar diaphragm
pumps except that piston slides up and down inside of a cylinder
Venturi - CORRECT ANSWER -Relies on the flow of compressed gas, or liquid
through a narrowed chamber expanding to a larger passage that creates suction from a port located at the point of expansion
Peristaltic - CORRECT ANSWER -Commonly referred to as a tube rotor pump,
develops a vacuum through positive pressure displacement
Thermotic - CORRECT ANSWER -Suction is created using an electric heater
inside a sealed chamber with 2 reed valves
Vacuum Regulator - CORRECT ANSWER -Maintains a desired level of suction
Collection containers - CORRECT ANSWER -Placed between suction
tip/catheter and suction unit for purpose of COLLECTING FLUIDS AND DEBRIS aspirated from body.
Bacterial Trap/Filter - CORRECT ANSWER -A component that traps moisture
and prevents bacterial contamination of the suction unit
Pressure Regulator - CORRECT ANSWER -Maintains a desired level of
pressure
Moisture Trap/Filter - CORRECT ANSWER -Traps moisture and oils and filters
out small particles of dirt and debris exiting the pressure developing mechanism
Sequential Compression Device (SCD) - CORRECT ANSWER -Use intermittent
pneumatic compression to help prevent blood clots in the deep veins of the legs
Continuous Positive Airway Pressure (CPAP) - CORRECT ANSWER -Maintains
a positive pressure on the airway for the purpose of splinting it open during rest
Continuous Ultrasound - CORRECT ANSWER -Ultrasonic vibrations that are
consistently ON during treatment
Effective Radiating Area (ERA) - CORRECT ANSWER -Area of the ultrasonic
transducer head, expressed in cm2, that produces the therapeutically effective ultrasonic vibrational energy
Frequency - CORRECT ANSWER -Number of ultrasonic vibrations that occur in
1 second
Intensity - CORRECT ANSWER -The concentration of vibrational energy applied
to the treatment area, measured in Watts/cm
Modality - CORRECT ANSWER -A specific method of therapy
Non-thermal - CORRECT ANSWER -Therapeutic application of pulsed
ultrasound waves of less than 50% duty cycle, that do NOT produce heating of the body tissues
Conditions for ultrasonic therapy unit - CORRECT ANSWER -Soft tissue,
muscles, joints
Absolute Zero - CORRECT ANSWER -Point at which atoms stop moving
Ambient Temperature - CORRECT ANSWER -The temperature of the
surrounding outside air
Compression - CORRECT ANSWER -Reduction of refrigerant volume to
increase pressure of a gas
Expansion - CORRECT ANSWER -Reduction of pressure on a refrigerant that
lowers the boiling point so heat can be absorbed
Heat - CORRECT ANSWER -Energy that can be moved from one point to
another and exists at temperatures above absolute zero
Refrigerant - CORRECT ANSWER -Liquid used in refrigeration systems
Thermoelectric Refrigeration - CORRECT ANSWER -Aka Peltier Effect. 1 side
of the material heats as the other side cools
Condenser Coils - CORRECT ANSWER -Exchange the warmth of the
refrigerant with the coolness of the ambient air
Evaporator Coils - CORRECT ANSWER -Exchange the warmth of the
environment with the coolness of the refrigerant
Filter/Dryer - CORRECT ANSWER -Removes moisture and impurities from the
refrigerant
Conduction - CORRECT ANSWER -Direct physical contact transfers heat from
a warmer body to a cooler object
Convection - CORRECT ANSWER -Transfer of heat through moving air and
water vapor molecules surrounding the body (fan)
Evaporation - CORRECT ANSWER -Loss of heat as liquid is converted into a
gas
Homeostasis - CORRECT ANSWER -The process of maintaining relatively
stable internal physiologic conditions, such as body temperature under fluctuations environmental conditions
Hyperthermia - CORRECT ANSWER -Core body temperature above 38.5° C
Hypothermia - CORRECT ANSWER -Core body temperature below 36.6° C
Intravascular - CORRECT ANSWER -Inside of a blood vessel
Invasive - CORRECT ANSWER -Therapeutic technique that requires entry into
a body cavity, breaking the integrity of the skin, or interruption of normal body functions
Non-invasive - CORRECT ANSWER -Therapeutic technique performed without
entry into a body cavity, breaking the integrity of the skin, or interruption of normal body functions
Radiation - CORRECT ANSWER -Heat moves as electromagnetic waves from
warmer objects to colder objects (sun rays)
Vascular insufficiency - CORRECT ANSWER -Decreased blood circulation near
the skin surface
Standby Mode - CORRECT ANSWER -Device is turned on without
administering therapy or monitoring the patient
Manual Mode - CORRECT ANSWER -Device monitors internal machine
temperature sensors to regulate the circulated air or fluid temperature
Automatic Mode - CORRECT ANSWER -Device monitors a patient core
temperature probe to regulate the circulated air or fluid temperature
Monitoring Mode - CORRECT ANSWER -Device does not administer therapy
but monitors the patient temperature prove to provide a displayed temperature
Hospital care areas where the patient warming/cooling system is used - CORRECT
ANSWER -Burn units, recovery rooms, operating rooms, emergency rooms, coronary
care units
Neonate - CORRECT ANSWER -Period of time covering the first 28 days after
birth
