CH 11: Pain Assessment Flashcards
pain is always?
subjective
what is pain assessment?
interpretation of scale number and critical thinking about influencing factors
signs of pain?
facial expression
guarding
moaning
vital changes
what can hypoventilation lead to?
hypoxia
collapsed alveoli
pain requires attention to what?
response to relief methods
medication side effects
what else can be done?
why is pain assessment important?
to develop non-pharmacological and pharmacological strategies to improve clinical results
-important for treatments, diagnoses, etc
pain assessment details?
intensity
location
onset (acute more emergent, chronic harder to treat)
referred or radiating
limitations of ADL
duration
alleviating and aggravating
what is holistic?
non pharma
holistic method examples?
distraction: music, relaxation, massage, acupuncture
tubes: decompress and relieve pressure
anxiolytics
improve breathing and oxygenation
positioning
heat/cold (good for musculoskeletal)
psychological support, palliative care, conflict resolution
what is nocioreception?
describes noxious stimuli perceived as pain
originates from CNS or PNS
nocireceptors?
specialized nerve endings that detect pain
transmit signals to sensory fibers: A (rapid signal, shorter term) and C (slower signal, persist after injury)
nociception concepts: transduction?
stimulus in periphery (cut or burn felt at peripheral level)
- mediators released: substance P, histamine, prostaglandins, serotonin, bradykinin
nociception concepts: transmission?
pain moves from spinal cord to brain (enacts reflexes to feel pain faster)
nociception concepts: perception?
conscious awareness of pain sensation (brain is aware)
-cortical structures (limbic system=emotional response)
only perceived as pain when reaches cortical structures
nociception concepts: modulation?
inhibition of pain sensation (how body reacts to pain - endogenous relievers)
-body’s built in mechanism to slow/stop pain stimulus
-analgesic effects (serotonin, norepi, neurotensin, GABA)
