The Physical Examination Ch. 2 Flashcards
The four major vital signs are
body temperature, pulse, RR, BP
What is the fifth vital sign
Pulse Ox (sp02)
Body temperature is routinely measured to assess for signs of…
inflammation or infection
Core temperature remains relatively constant at about…
37C or 98.6F
An increased in body temperature causes the blood vessels near the skin to dilate is a process called
vasodilation
Decrease in body temperature causes
vasoconstriction
What are the four common types of fevers?
Intermittent, Remittent, Relapsing and Constant
Intermittent fever is described as what kind of fever?
alternates at regular intervals periods of fevers and periods of normal or below normal temperatures (on and off)
Remittent fever, the pt has
peaks and valleys (more than 2C or 3.5F) over a 24 hour period
Relapsing fever is said to last
1 to 2 days, goes away and comes back
Constant or continuous fever is when pt’s body temp remains
above average without change
Hypothermia is the term to describe
core temperature below the normal range
Hypothermia may occur as a result of (3)
- excessive heat loss
- not able to create enough heat
- impaired thermal regulation
Signs of Hypothermia may include (5)
- decreased pulse and rr
- severe shivering
- coldness and chills
- skin pale or bluish
- Hypotension
Signs of severe Hypothermia may include
- loss of conciseness
- altered mental status
- coma
Interventions for Hypothermia (5)
- remove wet clothing
- provide dry clothing
- place pt in warm environment
- cover pt head w/ cap or towel
- supply warm oral or IV fluids
What are some factors that affect body temperature? (5)
Age, environment, time of day, exercise, stress, hormones
The four most commonly used sites for temperature are
- mouth
- rectum
- ear (tympanic)
- axilla
Rectum and tympanic are considered
core temperatures
What is generated through the vascular system w/ each ventricular contraction of the heart (systole)
pulse
a pulse is measured by
rate, rhythm, and strength
Normal pulse range in adults?
60 to 100
A HR lower than 60 bpm is called
bradycardia
A pulse rate greater than 100 is called
tachycardia
The diaphragm is the primary
muscle of respiration
What does the diaphragm do at the end of inspiration?
And causes the pressure in the lungs to__________
it relaxes and the natural elasticity (recoil) causes the pressure in the lung to increase
Normal RR is
12- 20 breaths per minute
Eupnea
Normal. RR 12-20
Bradypnea
Below 12 breaths
Tachypnea
More than 20 breaths
Apnea
No breathing
Hypoventilation
Decreased rate and depth
Hyperventilation
Increased rate and depth
Cheyenne-Stokes
Faster and deeper, then slower and shallower, ending with apnea
Kussmaul’s
Increased rate and depth; associated w. diabetic ketoacidosis
Biot’s
Fast and deep w. abrupt apnea
What is the force exerted by the circulating volume of blood on the walls of the arteries?
Arterial blood pressure
What is the term when the heart is contracting (top)?
Systolic blood pressure
What is the term when the heart is relaxed ( bottom)?
Diastolic blood pressure
Blood flow is equal to
cardiac output
What is the average cardio output
5L
What is the equation for CO
CO=SV x HR
When an individual’s blood pressure is chronically above normal range, this is called?
Hypertension
An elevated BP of UNKOWN cause is called
primary hypertension
