115 Unit 3 Flashcards
What are the cardinal vital signs?
Temperature Pulse Respiration BP O2 Saturation
____ is the temperature of deep tissues.
Core Temperature
Widening of blood vessels.
Vasodilation
Narrowing of blood vessels.
Vasoconstriction
____ occurs primarily in neonates because they cannot shiver, a limited amount of vascular brown adipose tissue present at birth can be metabolized for heat production.
Nonshivering thermogenesis
____ drastically lowers body temperature and typically presents on the forehead, upper chest, and arms.
Diaphoresis.
____ is another term for fever.
Pyrexia
____ occurs because heat loss mechanisms are unable to keep pace with excess heat production, resulting in an abnormal rise in body temperature.
Fever/Pyrexia
____ is pertaining to or characterized by an elevated body temperature.
Febrile
____ is being without fever.
Afebrile
____ are medications that reduce fever.
Antipyretics
____ is a dangerous heat emergency, defined as a body temperature of 40.2 C (104.4 F) or more.
Heat Stroke
____ is heat loss during prolonged exposure to cold overwhelms the ability of the body to produce heat.
Hypothermia
4 Patterns of fever.
Sustained
Intermittent
Remittent
Relapsing
____ rely on thermal radiation from the ear canal, tympanic membrane, axilla, and temporal artery to measure body temperature.
Infrared thermometers
____ contains a probe connected to a microprocessor chip, which translates signals into degrees and sends a temperature measurement to a digital display
Digital Thermometer
____ is an abnormally elevated heart rate, more than 100 bpm.
Tachycardia
____ is a slow heart rate, less than 60 bpm.
Bradycardia
____ is the deviation from the normal pattern of the heartbeat.
Dysrhythmia
____ is created by an inefficient contraction of the heart that fails to transmit a pulse wave to the peripheral pulse.
Pulse Deficit
____ is the difference between systolic and diastolic pressure.
Pulse pressure
____ is the most common alteration in blood pressure, and often an asymptomatic disorder characterized by persistently elevated bp greater than 140/90.
Hypertension
____ is the term for a blood pressure less than 90/60.
Hypotension
____ is referred to as postural hypotension. (a reduction of systolic of at least 20 and a reduction of diastolic of at least 10 within 3 minutes of standing.)
Orthostatic Hypotension
