Vital Signs Flashcards
What is the purpose of taking vital signs?
To monitor a change in a person condition
What do you do when the vital sign is abnormal?
Try to take it twice and switch arms & if still abnormal report to nurse
When do you asses vital signs?
-On admission
-Discharge
-Pre and Post-opt
-Change in condition
-Loss of consciousness
-When medications are given that affect cardiac rate and rhythm
-Per MD order or hospital policy
What are the physiological responses for temperature?
-disease or trauma of the hypothalamus or spinal cord will alter temperature
-hypothalamus also receives messages from cold and warm thermal receptors located throughout body
What is the most common way to take temp in a hospital?
Orally
What temp sites are considered core temp?
Tympanic, rectal, and temporal artery
What are surface temp measurement sites?
Skin, mouth, and axiallae
How do you take tympanic temp?
Pull up and back (ear)
What temp is more accurate?
Core temperature
What are the four mechanisms of heat transfer?
Radiation, Convection, Evaporation, and Conduction
What is radiation (mechanism of heat transfer)?
Diffusion or dissemination of heat by electromagnetic waves (ex. Gives of heat from uncovered areas)
What is convection (mechanism of heat transfer)?
Dissemination of heat by motion between areas of density (ex. Fan blows cool air across warm)
What is Evaporation (mechanism of heat transfer)?
Conversion of liquid to vapor (ex. Sweating)
What is conduction (mechanism of heat transfer)?
Transfer of heat to another object during contact (ex. Ice pack)
What is the primary source for body heat?
Metabolism
What other two mechanisms play a role in generation of body heat?
Hormones and exercise
What factors affect variations in temperature?
Circadian Rhythms, gender/age, illness, environment
What does pyrexia mean?
Has fever (febrile)
What does a febrile mean?
No fever
What is hyperpyrexia?
Condition where the body temp goes above 106.7 (life-threatening issue)
What is hypothermia?
Condition where the body temp drops really low, commonly caused by prolonged exposure to cold
What are the expected ranges in oral temp?
96.8 to 100.4 (average is 98.6)
What are expected ranges of rectal temp?
Usually 0.9 degrees higher than oral and tympanic
What is expected ranges of axillary temp?
Usually 0.9 degrees lower than oral and tympanic temp
What are expected temporal temp ranges?
Are close to rectal, but they are nearly 1 degree higher than oral and 2 degree higher than axillary
What are the fever signs/symptoms?
Hot, dry skin, flush, general malaise, and increased heart rate
What is intermittent fever?
Body temp comes back to normal in 24 hours
