Complete Guide .
afebrile - ANSWER: Without fever
antipyretic - ANSWER: Used to reduce fevers associated with a variety of conditions;
most common are aspirin, acetaminophen, and ibuprofen.
aphasia - ANSWER: Neurological disorder influencing the production and
understanding of language.
auscultatory gap - ANSWER: Disappearance of sound when obtaining a blood
pressure: typicallcy occurs between the first and second Korotkoff sounds.
basal metabolic rate (BMR) - ANSWER: Amount of energy used in a unit of time by a
fasting, resting subject to maintain vital functions.
blood pressure (BP) - ANSWER: Pressure exerted by the circulating volume of blood
on the walls of the arteries, veins, and chambers of the heart. The pressure in the
aorta and the large arteries of a healthy young adult is approximately 120 mm Hg
during systole and 70 mm Hg during diastole.
bradycardia - ANSWER: Slower than normal heart rate; heart contracts fewer than 60
times per minute.
cardiac output - ANSWER: Volume of blood expelled by the ventricles of the heart;
equal to the amount of blood ejected at each beat (the stroke output) multiplied by
the number of beats in the period of time used in the computation.
Celsius - ANSWER: Denotes a temperature scale in which 0° is the freezing point of
water and 100° is the boiling point of water at sea level.
conduction - ANSWER: Transfer of heat from one object to another with direct
contact.
convection - ANSWER: Transfer of heat away by air movement.
core temperature - ANSWER: Temperature of deep body tissues and organs.
diaphoresis - ANSWER: Secretion of sweat, especially profuse secretion associated
with an elevated body temperature, physical exertion, or emotional stress.
, diastolic pressure - ANSWER: Minimum level of blood pressure measured between
contractions of the heart.
diffusion - ANSWER: Movement of molecules from an area of higher concentration
to an area of lower concentration.
dysrhythmia - ANSWER: Heartbeat that deviates from the normal pattern.
eupnea - ANSWER: Normal respiration that is quiet, effortless, and rhythmic.
evaporation - ANSWER: Transfer of heat energy when a liquid is changed to gas.
Fahrenheit - ANSWER: Scale for the measurement of temperature in which the
boiling point of water is 212° and the freezing point is 32° at sea level.
febrile - ANSWER: Pertaining to or characterized by an elevated body temperature.
fever - ANSWER: Elevation of the hypothalamic set point so that body temperature is
regulated at a higher level.
fever of unknown origin (FUO) - ANSWER: Refers to a fever whose cause cannot be
determined.
frostbite - ANSWER: Traumatic effect of extreme cold on the skin and subcutaneous
tissues; first manifested by distinct pallor.
heat exhaustion - ANSWER: Abnormal condition characterized by weakness, vertigo,
nausea, muscle cramps, and loss of consciousness; caused by depletion of body fluid
and electrolytes resulting from exposure to intense heat or the inability to
acclimatize to heat.
heatstroke - ANSWER: Severe and sometimes fatal condition resulting from the
failure of the temperature-regulating capacity of the body; caused by prolonged
exposure to the sun or high temperatures.
hematocrit - ANSWER: Measure of the packed cell volume of red cells, expressed as
a percentage of the total blood volume.
hypertension - ANSWER: Blood pressure of greater than 120-139/80-89
hyperthermia - ANSWER: Situation in which body temperature exceeds the set point;
fever.
hypotension - ANSWER: Abnormal lowering of blood pressure in which pressure is
inadequate for normal perfusion and oxygenation of tissues.
