Body Temperature Flashcards
If body temperature falls
Blood vessels construct
Shivering (to make heat)
Hypothalamic regulator controls core temperature
If body temperature raises
The blood vessels dilate
Sweat glands secrete fluid
Hypothalamic regulator controls core temperature
Factors affecting body temperature
4
-Damage to the hypothalamic regulator
Eg)head trauma
-Age/sex
Eg)Women at progesterone at ovulation, young and old are more susceptible to change in temperature
-Disease/injury
Eg)infection can increase temperature, hyperthyroidism increase metabolism and raises temperature
-Circadian rhythms
Temporary artery method
(Most accurate for core temperature)
-contraindication?
No covering stuff
Eg) hair, hat
When would an oral temperature not be appropriate?
- clients who are not enable to follow simple direction
- unconscious or uncooperative
- any oral surgery
- breath through the mouth ( must close mouth during measuring)
Rectal temperature
Sims position with the upper leg flexed
Stool in the rectum can cause inaccurate readings.
How would you position the tympanic thermometer to achieve proper position?
Protesting the prove handle towards the jaw to aim the lens TOWARD the tympanic membrane.
Place the prove snugly into the clients OUTER ear canal
When applying the tympanic, how to pull the ear for adult and child?
For adult, pull the ear up and back
For kid, pull the ear down and back
What nerve makes the HR increase?
Accelerator nerve
(Sympathetic nerve)
Some sympathetic nerves are also on the walls of ventricles.
What nerve makes the HR decrease?
Vagus nerve
Parasympathetic
How the pulse is regulated?
By the pacemaker or sinoatrial nods (SN)
What the quality of the pulse represent?
The quality of the pulse represents the “volume of blood pumped by the contractions of the ventricles
When the peripheral pulse is too weak to feel what is indicated?
This can be a decrease in cardiac output
Or
Tissue perfusion problems
Arrhythmias are known as dysrhythmias are abnormal heart rhythms. How to take pulse
Heart rate or pulse for 1 min
When to take apical pulse?
The peripheral pulse is to weak to feel
The radial pulse is too weak/irregular
The rate is less than 60 beats
The patient who taking cardiac meds
