Q

what aspects of life can chronic pain affect

A

all even socioeconomic

45
Q

• neurologic transmission of pain is referred to as

A

nociception

46
Q

• because of connection between various parts of nervous sys involving pain signals what type of effects (broad terms) accompany pain?

A

vasomotor, autonomic and visceral effects accompany pain eg dec or ceased peristalsis in pt w sever pain

47
Q

algogenic=

A

causing pain

48
Q

as a result of the conscious perception of pain how may people report the same stimulus

A

people may report the same stimulus differently based on their anxiety level, past exp, and expectations

49
Q

for pain to be consciously perceived what must happen?

A

neurons in the ascending system must be activated. this happens as a result of input from nociceptors

50
Q

whats the decending control system and how can it be affected to relieve pain?

A

(System of fibres that originate in the lower and midportion of the brain and terminate n the inhibitory interneuronal fibres in the dorsal horn of the spinal cord)
-Always active-prevents continuous transmission of painful stimuli partly through the action of endorphins

51
Q

as nocicpetion of pain occurs what system is activated to inhibit pain?

A

descending control system

52
Q

• chemicals that reduce or inhibit perception of pain

?how?

A

endorphins and enkephalins (both endogenous, morphine like substances)
by stimulating the inhibitor interneuronal fibres which reduce the transmission of noxious impulses via the ascending system

53
Q

• prostaglandinds believed to inc the pain sensitivity of pain receptors by enhancing the pain provoking effect of _______

A

bradykinin

54
Q

in the peripheral nervous sytem there are type A delta fibres transmit nociception rapidly-fast pain. Type c fires transmit second pain (dull aching burning)
if theres repeated type C pain what should the nurse do and why?

A

fi repeated type C pain theres greater response in dorsal horn network. Therefore, imp to treat pts w analgesic agents when they first feel pain.

55
Q

the strategy of distraction works on which system?

is it long lasting

A

• Cognitive proc may stim endorphin prod in the descending control system and inc activity in the system

eg distraction amplifies this and pt may report less pain when visitiors there or when watching TV

once the distraction ends the activity in the descending control system ceases resulting in inc transmission of painful stimuli

56
Q

which theory of pain was first to articulate the existence of a pain modulating system

A

gate control theory

57
Q

gate control theory of pain

A

stimulation of the various sizes of nerve fibres have different effects eg stim of lg diameter fibres inhibits the transmission of pain and closes the gate. the mechanism of opening and closing the gate in influenced by nerve impulses that descend from the brain

58
Q

the gate control theory of pain guided research towards…

A

identifying cognitive behavioural approaches to pain mgmt

it explains how distraction and music therapy relieve pain

59
Q

Factors influencing the pain response

• May inc or dec perception, tolerance and also affect responses

A 
past exp
anxiety and depressio
culture
gender
age
60
Q

how does past exp influence pain

A

Past exp
• The more exp people have w pain, the more frightened they are likely to be and less able to tolerate, want relief sooner. Esp if pains been pooly managed in the past
• If past pain was constant and unrelenting they may become irritable, withdrawn and depressed
• Nurses should be aware of pts previous exp w pain
• If pain relieved promptly and adequately the person may be less fearful fo future pain and better able to tolerate it

61
Q

how does anxiety influence pain

A

doenst nec inc it. sometimes it distracts the pt fromt he pain.

62
Q

it is more effective to relieve pain by directing Tx at anxiety

A

no. treat the pain

63
Q

how does Routine use of antianxiety meds affect pain

A

may prevent pts from reporting pain because of sedation and may impair their ability to take deep breaths, get out of bed and cooperate with tx plan

treat the pain

65
Q

T or F people from diff cultures who exp the same intesity of pain wont report it the same way but will respond in the same way

A

F. both the response and reporting may be different

66
Q

factors that help explain the diff between cultural groups

A

• Age, gender, education, income help explain hese diffs
the degree that the pt identifies with their cult
their interactions w the health care system

67
Q

T or F sociocultural mechanisms are solely responsible for cult differences in pain

F • Psychological, sociocultural, biological mechanisms are responsible for cult differences in pain

68
Q

are wait times in Canadian hospitals related to related to pt reports of pain

A

no

69
Q

which ethnicity waits longer in ER vs __

A

• African Canadians waited longer to be seen than Caucasian pts

70
Q

should the nurse react to the pts perception of pain or their behaviour and why?

A

• Nurse should react to the pts perception of pain and not the persons behaviour because the persons behaviour may differ from the nurses cultural expectations

71
Q

how can the nurse be sensitive to how pain affects culture?

A

recognize how your values differ fromt he values of other cultures, this helps avoid falling into expectations or stereotyping
recog that cult diffs exist

A

teach how and what to communicate abt their pain

73
Q

what should a nurse be aware of in r/t older adults and Sx

74
Q

what should the nurse assume abt a pt who is older and pain

A

dont assume! its not normal part of aging

• Judgments abt pain and the adequacy of Tx should be based on the pts report of pain and pain relief not age

75
Q

what do older adults often fear surrounding pain and Tx

A

addiction

76
Q

T or F older adults exp more pain

why?

A

F

• Loss of un/myelinated fibres in peripheral n sys—may lead to diminished pain perception. Some say d/t a disease proc

77
Q

gerontologic considerations influencing the pain response

A
  • Loss of un/myelinated fibres in peripheral n sys—may lead to diminished pain perception. Some say d/t a disease proc
  • Some older a believe pain is normal part of agin
  • They may not know how to describe it
  • Older a have slower metb and greater ratio of body fat-muscle mass-smaller doses may be sufficient to treat
  • Many fear addiction
  • Older a must receive adequate pain relief after Sx or trauma. When olde pt becomes confused after Sx or trauma its often attributed to meds which are then discount but it might be from pain

how is your daily life affected by pain

some may be able to continue to work

93
Q

how dyou treat unconscious pt in regards to pain

A

• In unconscious pts pain should be assumed to be present and be treated

94
Q

how should physiologic responses to pain be used

o	Mydriasis (ilation of the pupil of the eye.)
o	Hypervigilance
o	Inc muscle tone
o	All of the above are r/t activation of the autonomic n sys
99
Q

sensitization=

A

• Sensitization-a heightened response seen after exposure to a noxious stim. Reponse to the same stim is to feel more pain

100
Q

some ways to provide nursing care to pt in pain

A
  • To improve pt comfort keep them comfy and brush hair etc
  • Teaching in advance may dec anxiety
  • Learning about ways to dec pain in advance can empower them
  • Many pts believe that they shouldn’t request pain relief until they cant tolerate the pain. Explain to them value of early Tx
101
Q

considerations for pain at end of life

A

Pain at end of life
• Pain is one of most feared symp at EOL
• Barriers: addiction fears and lack of edu
• Requires comprehensive ass and mgmt which can be difficult bec of confusion, delirium, unconsciousness
• Caregivers are taught to observe for signs of restlessness or facial expressions as a prox indicator of pain
• Neuropathic pain requires a diff type of Tx than acute pain

102
Q

a method to dec anxiety r/t pain Tx

A

teach the pt what degree of relief from each tx theyre likely to experience

103
Q

End of life tx of pain and opioids

A
  • Ass for resp depression-rate depth and LOC monitored. A resp rate of 6 or greater is usually enough to not be depression.
  • If resp depression occurs a dec in dose may be nec as well as freq stim to do deep breath exercises until metb of opioid. Comfort should be priority when EOL.
  • Bowel regimen and other side e must be managed
104
Q

what is the goal of pain mgmt strategies

A

to completely relieve pain. not reduce it to bearable levels

105
Q

whats a surprising thing you should assess when treating pain pharmacologically

A

Pharmacologic interventions
• Ass pts rcial and ethnic background (genetics plays role in varied responses to NSAIDS and opioids esp w codeine where they don’t get its analgesic effect

106
Q

pt has pruritus in response to opioids. are they allergic?

A

probably not. this is common side e

107
Q

how can you know wehn to inc dose of opioid

A

• Ass vitals including pain score before giving opioid and if within half hr pain is still present but resps bp etc are good then some change in analgesia is nec

108
Q

opioid tolerance and addiction

A
  • Theres no known max safe dose of opioids or easily identifiable therapeutic serum level
  • All individual
  • Tolerance dev in almost all pts taking them for a time
  • Pts tolerant of lg doses of morphine may benefit from switching to diff opioid
  • Symptoms of dependence may occur when the opioids are discontinued. Dependence often occurs w opioid tolerance and doesn’t indicate an addiction
  • Ddiction is very negigiblewhen giving therapeutic doses
  • When caring for pt w hx of addiction consider that ea person has right to be treated for pain
