Vital Signs Test Flashcards
Hyperthermia
Occurs when the body temperature exceeds 104°F
Hypothermia
Occurs when the body temperature is below 95°F
Temperature
The balance between heat loss and heat produced
Oral temperature site
Mouth 98.6°F
Oral temperature length of time
3 to 5 minutes
What temperature site is most accurate
Rectal/Temporal
What degrees Fahrenheit is considered normal
97 to 100°F
Two reasons temperature can vary
Food or drink within 15 minutes or physical activity
Why are probe covers used on glass clinical or electronic thermometers
To prevent cross-contamination
Bradycardia
Pulse under 60 bpm
Pulse
Refers to the pressure of blood pushing against the wall of the arteries of the heart beats and rests
Tachycardia
Pulse rate over 100 bpm
Most frequent pulse site
Radial
Normal pulse range for adults
60 to 100 beats for minute
Three factors that must be noted about pulse
Rate rhythm and volume
Increased pulse rate factor
Exercise
Decreased pulse rate factor
Sleep
Reason that a pulse must be taken at the apical site
Week or rapid pulse
Pulse deficit formula
Apical pulse over radial pulse
Apnea
Lack of breathing
Bradypnea
Slow breathing
Dyspnea
Difficult breathing
Respiration
Process of intaking air
Tachypnea
Rapid breathing (above 25 respirations per minute)
Why do you count respirations while your fingers are still on the radial pulse
So the patient doesn’t know what you’re taking
Two characteristics used to describe respirations
Regular or irregular
Two words to describe the volume or character of respirations
Deep or labored
Respiratory rate for adults
12 to 20 per minute
Blood pressure
Measurement of the pressure that blood exerts on the walls of the arteries during vigorous activities
Hypertension
High blood pressure of 140 mmHg over 90 mmHg
Hypotension
Low blood pressure
Average blood pressure reading
120/80
Hypotension causes
Shock
What is orthostatic or postural hypotension
A sudden drop in systolic and diastolic pressure
What causes orthostatic or postural hypotension
When someone was from sitting/laying position to a standing position
2 causes of hypertension
Excitement and obesity
What pressure indicates hypertension
140/90
Why is it so important that you use the correct size blood pressure cuff to obtain your reading
To prevent inaccuracy
