Aural/tympanic and RectalHealth Sciences 2
Vital Signs-Temperature
Slide2The Basics of Aural Temperature
Also called tympanic temperature in reference to the eardrum (aka the tympanic membrane)
Thermometer detects and measures thermal, infrared energy radiating from the blood vessels in the eardrum
Measures body core temperature
Slide3Reasons for
Quick for infants and small children
When it is contraindicated for oral such as patient’s with limited consciousness or seizures
Slide4Contraindications
Ear canal misshapen
A lot of ear wax in canal
Active middle ear infectionSore earRecent ear surgery
Slide5Type of Thermometer
Hand held temperature probe with disposable tip cover.
Digital recording and reading
Thermometer beeps usually within 2 seconds.
Slide6Measuring Aural Temperature
Infants under 1 year
Pull ear pinna straight back
Infants over 1 year and adultsPull ear pinna straight back and down
Positioning the pinna correctly straightens the auditory canal so the probe will point directly at the tympanic membrane
Pull ear pinna straight back and down
Slide7Taking Aural Temperature
Slide8Basics of Rectal Temperature
Can use either clinical or electronic thermometer
It is an internal measurement
It is the most accurateFrequently taken on infants and small children
Slide9Reasons for Taking Rectal Temperature
The rectal procedure is normally used for an infant or young
child
It can also be used for a patient who is unconscious or irrational
If your patient has
difficulty breathing with his mouth
closed, you could use rectal
The
rectal route is used in the case of any suspected environmental injury such as heatstroke or hypothermia.
Slide10Contraindications for Rectal Temperature
If the
patient has a heart
condition; you can stimulate the Vagus nerve and cause cardiac
arrythmias
If the
patient has
hemorrhoids; its an enlarged vein and you can cause bleeding and pain as a result
If the
patient has recently under gone
rectal, anal, vaginal, or prostate surgery.If the
patient has
diarrhea; you can stimulate bowel movement
If the patient has fecal impaction (you can record incorrect temperature)
If the patient has bleeding tendencies from medications such as heparin or low platelets
And age related contraindications; if patient over 80 years old
Slide11Types of Thermometers
Electronic
Can be used for oral, rectal, or axillary

Slide12Types of Thermometer
Clinical thermometers
Slender glass tube containing
mercury or colored fluidTypes
Oral – blue tip, long slender bulb, marked oral
Security – plain tip
Rectal – red tip, short stubby bulb, marked rectal
Slide13Measuring Rectal Temperature
Follow standard precautions/wash hands and glove
Have thermometer, probe cover, and lubricant
If adult, place patient on left side in Sim’s positionIf infant, place on abdomen or lay on their back with legs secured
Use lubricant on tip of thermometer and gently insert 1-1 ½ inches into the rectum for adult and ½-1 inch into rectum for infant
Hold in place for 3-5 minutes
Do not let go of thermometer-it can slide in further or break
