Vital Signs Flashcards
- measurements of the body’s basic functions
- the most frequent and routine measurements obtained by health care providers
Vital Signs
What are the Vital signs
-temperature
-pulse
-blood pressure
-respiratory rate
often:
-oxygen saturation
-pain
what can cause a patient’s vital signs to change
- temperature of environment
- patient’s physical exertion
- effects of illness
guidelines for measuring vital signs
- )measuring, reviewing, and interpreting is nurse responsibility
- )make sure equipment is working properly
- )select equipment based on the patient
- )know the patient’s usual range of vital signs for basis
- )know the patient’s medical history, therapies, and prescribed medication
- )control or minimize environmental factors that can affect the patient’s vital signs
- )use a system or step by step approach to ensure accuracy
- )collaborate with health care providers for the frequency of vital sign assessments
- )use vital sign measurements to determine indications for medication administration
- )analyze results of vital signs based on patient’s condition and past medical history
- )verify and communicate significant changes in vital signs
- )instruct the patient and family in vital signs assessment and significant findings
acceptable temperature range for adults
range: 36 to 38 degree C (96.8 to 100.4 degree F)
oral average: 37 degree C (98.6 degree F)
rectal average: 37.5 C (99.5 F)
Axillary average: 36.5 C (97.7 F)
how much higher is rectal temperature than oral?
0.9 F or 0.5 C
how much lower is axillary and tympanic from oral temperature?
0.9 F or 0.5 C
When do you measure vital signs?
- on admission to health care facility
- when assessing a patient during home care visits
- on routine schedule under physician order
- standard procedure before, during, and after surgical procedures or invasive procedure
- before, during, and after blood transfusion
- before, during, and after administration of medication or therapies that affect cardiovascular, respiratory, or temperature functions
- when a patient’s general condition changes ( loss of conciseness or intense pain)
- before, during, after nursing interventions ( before ambulation or before performing exercises)
- when a patient reports nonspecific symptoms of physical distress
Body temperature
heat produced - heat lost due to environment = Body temperature
- Average body temperature for young adults
- average body temperature for elderly
- 37 C(98.6 F)
- 36 to 38 C (95 to 97 F)
lowest and highest temperature during the day
lowest: 6:00 am
highest: 4:00pm
physiological and behavioral mechanisms that regulate the balance between heat lost and heat produced
thermoregulation
- anterior hypothalamus
- posterior hypothalamus
- anterior controls heat loss
- posterior controls heat production
heat loss mechanisms
- sweating
- vasodilation
- inhibition of heat production
Heat production
- BMR
- voluntary movement like exercise
- Shivering
- nonshivering thermogenisis
