Vital Signs Flashcards
Heat produced - heat lost
Body temperature
Acceptable temp for Fahrenheit
96.8° F to 100.4° F
Acceptable temp for Celsius
36° C to 38° C
What controls body temp like a thermostat?
Hypothalamus
What 5 things regulate body temperature?
Neural and vascular control Heat production Heat loss (radiation, conduction, convection, evaporation) Skin temperature regulation Behavioral control
7 Factors that affect body temperature
Age Exercise Hormone level Circadian rhythm Stress Environment Temperature alterations
Heat-loss mechanisms are unable to keep pace with excessive heat production
Fever (pyrexia)
Have fever
Do not have fever
Febrile
Afebrile
hypothalamus isn’t working correctly
Hyperthermia
Acceptable pulse rate
60-100bpm
Acceptable respirations
12-20bpm
Acceptable blood pressure
120/80 mm Hg
Risk for Imbalanced Body Temperature
Hyperthermia
Hypothermia
Ineffective Thermoregulation
Examples of nursing diagnosis for pt with body temperature alterations
How to reduce fever (6)
Antipyretics (meds) obtain blood cultures minimize heat production Maximize heat loss increase metabolic rate (oxygen levels) pt comfort
When do you want to draw a culture?
Before starting antibiotics
Palpable bounding of blood flow noted at various points on the body
The indicator of circulatory status
Pulse
HR (same thing as pulse)
Number of pulsing sensations in 1 minute
Pulse rate
Electrical impulses
originate from the sinoatrial (SA) node
Characteristics of Pulse (4 things)
Rate (# per minute)
Rhythm (intervals)
Strength (0-4) volume of blood ejected
Equality (compare sides)
Factors that affect pulse (7 things)
Exercise Temperature Emotions Medications Hemorrhage Postural changes Pulmonary conditions
difference b/w peripheral & apical pulses
pulse deficit
0 1 2 3 4 strength of pulse is recorded as
0= absent 1= weak or thready 2=normal 3 =full or strong 4= bounding
Sites for pulse (10 sites)
Temporal Carotid Apical Brachial Radial Ulnar Femoral Popliteal Post. tib Dorsal pedis
7 things that determine what the pulse will be like
Activity intolerance
Anxiety
Acute Pain
Decreased cardiac output
Deficient/excess fluid volume
Impaired gas exchange
Ineffective peripheral tissue perfusion
Movement of gases into and out of the lung.
Ventilation
