14.2 - Measuring and Recording Temperature Unit 14 14.2 - Measuring and Recording Temperature
What is temperature? The balance between heat lost and heat produced by the body
Why might temperature vary? Individual differences Time of day Parts of the body
Normal Range for Body Temperature 97 – 100° F or 36.1 – 37.8° C Normal reading and times by method Oral 98.6°F or 37°C 3-5 min Rectal 99.6° or 37.6°C Axillary 97.6°F or 36.4°C 10 min
Most accurate method of measurement? Rectal – because it is an internal measurement
Least accurate method of measurement? Axillary or groin – because it is an external measurement
What is “aural” temperature? Temperature recorded in ear or auditory canal Measures thermal infrared energy radiating from tympanic membrane or eardrum
Hyperthermia or Hypothermia? Hyperthermia is high body temperature above 104°F (40°C) Hypothermia is low body temperature below 95°F (35°C)
Oral or Rectal clinical thermometer? A rectal thermometer has a short, stubby rounded bulb and can have a red tip
How do you clean up and dispose of a broken clinical thermometer? Put on gloves, use two cards to push droplets of mercury and glass into a plastic container with a tight fitting lid, wipe area with a damp sponge, put all cleanup material into plastic container, label “Mercury for recycling,” and take tightly sealed container to mercury recycling center
How do you prevent cross-contamination while using the probe of an electronic thermometer? Place a disposable cover over the probe
How do plastic and paper thermometers register temperature? Special chemical dots or strips change color when exposed to specific temperatures
What if the patient has eaten, smoked, or had something to drink shortly before taking a temperature? These can all alter the temperature in the mouth
How long should a thermometer soak in disinfectant (after cleaning) before it is safe to rinse in cold water and use on a patient? 30 minutes
