Vital Signs Flashcards
Clinical measurement of temperature, pulse, respiration and blood pressure and give some indication of the state of health of an individual. Ir represents interrelated physiologic systems of the body
Vital Signs
Purposes of Vital Signs
- universally communicate a patient’s condition and severity of disease
- helps in identifying nursing diagnosis, assess interventions and make decisions concerning the reponse of patients to treatment
Normal Range of Temperature
36-37.5 degrees Celsius
temperature of internal organs
core temperature
temperature of skin, outside surface
surface temperature
Purposes of taking temperature:
- establish data for subsequent evaluation
- check whether the core temperature is within normal range
- determine changes in response to specific therapies
surface-surface without contact
Radiation
molecule-molecule with contact
Conduction
dispersion of heat through air currents
Convection
continuous evaporation of moisture from the repiratory tract, oral mucoda and skin
Vaporation
patients having fever
febrile
Methods of taking Temperature:
- Oral
- Axillary
- Rectal
- Non-contact
it is the difference between heat produced and heat lost by the body and is measured through the use of a thermometer
Temperature
Contraindications for Oral Method
- infants
- unconscious and irrational patients
- patients who breath through their mouths
- those with disease of the oral cavity or surgery of the nose or mouth
- patients who have had taken cold or hot foods or fluids
Purposes of Rectal Method
- to obtain first temperature of newborn to check rectal patency
- to check core temperature of an adult
contraindications for Rectal Method
- patients with recent rectal surgery
- patients having diarrhea
- patients having disease of the rectum
- patients having cardiovascular alternation because the thermometer may stimulate the vagus nerve causing bradycardia or rhythm disorder
- Patients with leukemia which may traumatize the rectal mucosa causing bleeding
it is a rhythmical throbbing that results from a wave of blood passing through an artery as the heart contracts
Pulse
possible sites for taking pulse:
apical
radial artery
facial artery
temporal artery
dorsalis pedis
femoral artery
popliteal artery
carotid artery
bracial artery
posterior tibialis
what to note when taking pulse:
rate
rhythm or regularity
tension or compressibility
volume
