NUR 325 Pain
Pain - answer whatever the experiencing person says it is, existing whenever he says it
does
Acute pain - answer sudden onset and short duration
-linked to a specific injury or event that heals within normal time
-considered normal and part of body defense mechanism
Chronic pain - answer lasting more than 3 months (may last for years)
--viewed as pathologic
Nociceptive pain - answer Brain receives info from nociception and interprets it as
painful stimuli---considered the normal
pain location - answer localized or widespread (throughout the body)
pain intensity - answer on-minimal
moderate
severe
1-10
frequency of pain - answerconstant, intermittent, occasional
somatosensory system - answera set of specialized receptors and neural mechanisms
responsible for body sensations such as touch and pain
Nociceptors - answerpain receptors
Where are nociceptors found? - answerin every tissue of the body except the brain
Nociception - answertissue injury activates niciceptors to transmit pain through
somatosensory system
nociceptive pain - answerpain from a normal process that results in noxious stimuli
being perceived as painful
--protective mechanism to alert brain
Does nociception always result in nociceptive pain? - answerNo
chemical mediators of pain
(activate nociceptors) - answerprostoglandins
bradykinins
, serotonin
substance P
histamine
transduction of pain - answerbegins when tissue damage causes the release of
substances that stimulates the nociceptors and initiate action potential
transmission of pain - answermovement of pain impulses from the site of nociceptor
activation to the spinal cord
C fibers - answerunmyelinated, slow-conducting fibers that carry peripheral impulses
associated with pain to the spinal cord
--burning, aching
A8 fibers - answermyelinated sensory fibers
fast
sharp, stabbing sensations
perception of pain - answerfibers from thalamus send message to somatosensory
cortex, front/parietal lobes and limbic system
modulation of pain - answermidbrain releases substances:
endorphins
serotonin
dynorphin
Is chronic pain in older adults normal? - answerIt is prevalent but NOT A NORMAL
PART OF AGING
Eudynic pain - answernormal transduction of pain sensation by nociceptors
the following examples describe what type of pain?
-sunburn
-surgery
-trauma - answernociceptive pain
Nociceptive (somatic) pain - answersharp pain that is well localized to a specific area
nociceptive (visceral) pain - answerarises from within the body cavity
-thorax
-abdomen
pelvis
neuropathic pain - answerabnormal processing of pain message; burning, shooting in
nature
**results from pathology or disease of the somatosensory system
