PAIN Flashcards
It is defined by the person experiencing it, and it
exists according to their own perception and
description
pain
It is whatever the patient says it is
pain
It is subjective in nature, only the person
experiencing it may describe it and highly
individualized
pain
A sensation of physical or mental hurt
or suffering that causes distress or
agony to one experiencing it.
pain
it provides
warning signal for tissue injury. It
helps minimize injury and is often a called what?
protective/protective mechanism
The alleviation of pain or a reduction
in pain to a level of comfort that is
acceptable to the client.
pain management
Effective pain management is an
important aspect of nursing care to
promote what?
healing
prevent complications
reduce suffering
prevent the development of incurable
pain states
theories of pain?
Pattern Theory
Specificity Theory
Gate Control Theory
Affect Theory
Parallel Processing
Model
It states that pain is
perceived whenever the
stimulus is intense enough
Pattern Theory
A theory maintaining that
the nerve impulse pattern
for pain is produced by
intense stimulation of non-
specific receptors
Pattern Theory
It states that there are
specific nerve receptors for
particular stimuli.
Specificity Theory
what is the nerve receptor for noxious stimuli?
nociceptors
what is the nerve receptor for heat or cold?
thermoceptor
what is the nerve receptor for pressure, pulling or tearing sensation?
mechanoceptor
what is the nerve receptor for chemicals?
chemoceptors
What theory conceptualizes that there is a gate in the spinal cord which can modulate pain signals?
Gate Control Theory
What is the gate in the spinal cord called, as conceptualized in pain modulation theories?
Substantia Gelatinosa Cells
What types of interventions can help explain why pain relief is achieved through the modulation of the spinal cord gate?
electrical and mechanical intervention
It avers that the pain
is emotional
Affect Theory
What theory explains that the intensity of perceived pain depends on the value of the organ affected to the individual?
Affect Theory
What model believes that the physiologic or neurologic deciphering of the pain sensation and the cognitive emotional properties occur along different nerve fibers?
Parallel Processing model
WHAT ARE THE PHYSIOLOGY OF PAIN?
TRANSDUCTION
TRANSMISSION
PERCEPTION
MODULATION
Thermal, chemical or
mechanical stimuli (Pain-
producing stimuli)
Transduction
Stimuli causes cellular damage
leading to a release of
neurotransmitters
Transmission
Person becomes aware of the
pain
Perception
determines the pain
intensity and location
Somatosensory cortex
mainly the limbic system
determines how the person perceives it
Association cortex
What term describes the behavioral and physiological response that occurs after an individual feels pain?
Reaction
Neuromodulators are released
the moment pain is perceived
by the brain
Modulation
Which type of nerve fibers deliver sensory impulses to the spinal cord, where they synapse with spinal motor neurons?
Delta A fiber
WHAT ARE THE NEUROTRANSMITTERS (EXCITATORY):
PROSTAGLANDINS
BRADYKININ
SUBSTANCE P
HISTAMINE
SEROTONIN
What substances, produced through the breakdown of phospholipids found in cellular membranes, are known to increase pain sensitivity?
PROSTAGLANDINS
What substance, released from plasma that escapes from neighboring blood vessels at the location of tissue damage, attaches to receptors on peripheral nerves, amplifying sensations of pain, and also attaches to cells initiating the cascade leading to the production of prostaglandins?
BRADYKININ
What substance, discovered within the pain neurons of the dorsal horn and acting as an excitatory peptide, is required for the transmission of pain signals from the periphery to higher centers in the brain, and also induces vasodilation and edema?
SUBSTANCE P
