What are the four nociceptive pain processes of the pain experience? What does this provide guidelines for?
transmission, transduction, perception, and modulation
selecting pain relief measures
A person’s _______ background influences the meaning of pain and how it is expressed.
cultural
It is ___________ for older patients not to report pain.
common
Patients who are in ________ pain are unlikely to show behavioral changes.
chronic
The difference between acute and chronic pain involves the concept of ______. Acute pain is protective, thus preventing the harm; chronic pain is no longer protective.
harm
_______ pain is protective, thus preventing harm.
_______ pain is not protective.
Acute
Chronic
Do not collect an in-depth pain ________ when the patient is experiencing severe discomfort.
history
Pain causes physical signs and symptoms similar to those of other ________.
diseases
Individualize pain interventions by collaborating closely with the ________, using assessment findings, and trying a variety of interventions.
patient
Eliminating sources of painful _______ is a basic nursing measure for promoting _______.
stimuli
comfort
Using a regular schedule ________ for analgesic administration is more effective than an _________ schedule in pain control.
Around The Clock ATC
as needed PRN
________ is an adverse effect of opioids that always precedes respiratory depression (which is rare).
Sedation
A ________ device gives patients pain control with low risk of overdose.
Patient Controlled Analgesia PCA
While caring for a patient who receives local anesthesia, protect him or her from ______.
injury
Nursing implications for administering epidural analgesia include preventing _______ and monitoring closely for __________.
infection
respiratory depression
________ rarely occurs in patients who take opioids to relieve pain.
Addiction
The goal of _______ is to anticipate and prevent pain rather than treat it.
pain management
Pain ________ includes measuring the changing character of pain, the patient’s response to interventions, and the patient’s perceptions of the effectiveness of a therapy.
evaluation
According to the American Bar Association, _________ is a basic right of people who are seriously ill. Nurses are legally and ethically responsible for managing pain and relieving suffering.
pain management
Pain uses a person’s ______. It interferes with personal relationships and influences the meaning of life. You cannot measure it objectively. Only the patient knows whether pain is present and how the experience feels. It is not the responsibility of patients to prove that they are in pain; it is a nurse’s responsibility to ______ their report
energy
accept
Thermal, chemical, or mechanical stimuli usually cause _______.
pain
__________ converts energy produced by painful stimuli into electrical energy This begins in the periphery when a pain-producing stimulus sends an impulse across a sensory peripheral pain nerve fiber (nociceptor), initiating an ____________.
Transduction
action potential
Once transduction is complete, ________ of the pain impulse begins. These pain-sensitizing substances surround the pain fibers in the extracellular fluid, creating an “inflammatory soup,” spreading the pain message and causing an inflammatory response. The pain stimulus enters the spinal cord via the _________ and travels one of several routes until ending within the gray matter of the spinal cord. At the dorsal horn __________ is released, causing a synaptic transmission from the afferent (sensory) peripheral nerve to spinothalamic tract nerves, which cross to the opposite side.
transmission
dorsal horn
substance P
Nerve impulses related to painful stimuli travel along _________ (sensory) peripheral nerves. Two types of peripheral nerve fibers conduct painful stimuli: the fast, myelinated _______ fibers and the very small, slow, unmyelinated ________.
afferent
A-delta
C fibers
Along the _______ tract pain impulses travel up the spinal cord. After the pain impulse ascends the spinal cord, the thalamus transmits information to higher centers in the brain, including the ________ formation, _______ system, somatosensory cortex, and association cortex.
spinothalamic
reticular
limbic
Cellular damage caused by thermal, mechanical, or chemical stimuli results in the release of what four excitatory neurotransmitters?
prostaglandins, bradykinin, substance P, and histamine.
The ____ fibers send sharp, localized, and distinct sensations that specify the source of the pain and detect its intensity.
A-Delta
The _____ fibers relay impulses that are poorly localized, burning, and persistent.
C-Fibers
For example, after stepping on a nail, a person initially feels a sharp, localized pain, which is a result of ___-fiber transmission. Within a few seconds the pain becomes more diffuse and widespread, until the whole foot hurts because of ___-fiber innervation’s
A
C
Once a pain stimulus reaches the _______, the brain interprets the quality of the pain and processes information from past experience, knowledge, and cultural associations in the perception of the pain
cerebral cortex
• Generated from the breakdown of phospholipids in cell membranes
• Thought to increase sensitivity to pain
What neurotransmitter is this?
Prostaglandins
• Released from plasma that leaks from surrounding blood vessels at the site of tissue injury
• Binds to receptors on peripheral nerves, increasing pain stimuli
• Binds to cells that cause the chain reaction producing prostaglandins
What neurotransmitter is this?
Bradykinin
• Found in the pain neurons of the dorsal horn (excitatory peptide)
• Needed to transmit pain impulses from the periphery to higher brain centers
• Causes vasodilation and edema
What neurotransmitter is this?
Substance P
• Produced by mast cells causing capillary dilation and increases capillary permeability
What neurotransmitter is this?
Histamine
• Released from the brainstem and dorsal horn to inhibit pain transmission
What neurotransmitter is this?
Serotonin
• Are natural supply of morphine-like substances in the body
• Activated by stress and pain
• Located within the brain, spinal cord, and gastrointestinal tract
• Cause analgesia when they attach to opiate receptors in the brain
• Present in higher levels in people who have less pain than others with a similar injury
What neurotransmitter is this?
Neuromodulators (Inhibitory)
______ is the point at which a person is aware of pain. The ________ cortex identifies the location and intensity of pain, whereas the association cortex, primarily the ________ system, determines how a person feels about it. There is no single pain center
Perception
somatosensory
Limbic
Once the brain perceives pain, there is a release of what four inhibitory neurotransmitters which work to hinder the transmission of pain and help produce an analgesic effect.
endogenous opioids,
serotonin,
norepinephrine,
gamma aminobutyric acid (GABA),
This inhibition of the pain impulse is the fourth and last phase of the nociceptive process known as _______.
modulation
