Vital Signs Flashcards
What are the factors that affect vital signs?
medications, illness/infection, age, hypovolemia/dehydration, environment, PO intake, hormones, circadian rhythm
What is the normal range for temperature and where are the sites?
36-38 degrees and at oral, axillary, temporal, tympanic, rectal
-core temperature is at the pulmonary artery
Pyrexia
fever– occurs when the heat-loss mechanisms are unable to keep pace with excess heat production
Hyperthermia
when the body is unable to release excess heat, resulting in a high temperature
Hyperpyrexia
is a very high fever 41 degrees or higher
Febrile
when a client has an elevated temperature, they are “febrile”– describes the client and not the temperature itself
Afebrile
descriptive word for when a client does NOT have a fever– describes the client and not the temperature itself
Hypothermia
occurs when the body temperature is 36 degrees or less–can be classified as mild or severe
What causes the pulse?
forceful contraction that pumps blood out of the left ventricle to the periphery of the body
What is the cardiac output (CO)?
the volume of blood pumped in one minute– about 5L
What is the average heart rate for an adult?
60-100 bpm
What is stroke volume?
the amount of blood that enters the aorta with each ventricular contraction– usually 60-70mL
Tachycardia
an abnormally fast heart rate of greater than 100bpm– can be caused by exercise, fever (and heat), anxiety, medications, etc.
Bradycardia
a slow heart rate of less than 60bpm– can be caused by long-term exercise, hypothermia, relaxation, medications. etc.
Pulse deficit
a difference between the apical and radial pulse rate– can be caused by cardiovascular disease
Apical-radial pulse deficit
same as pulse deficit, it is the difference between apical and radial pulse rates
