24
when describing pain what are the three categories we ask about?
quality periodicity intensity
25
what are some examples of descriptors for quality of pain?
sharp, dull, aching, throbbing, stabbing, burning
26
what are some examples of descriptors for periodicity of pain?
-episodic (related to something= period, migraines) -intermittent (comes and goes) -constant
27
what are some examples of descriptors for intensity of pain?
mild (1-3), moderate (4-6), severe (7-10), intolerable
28
what are the four mechanisms of pain perception?
1. transduction 2. transmission 3. perception 4. modulation
29
what is perception?
recognizing and defining pain in the cortex
29
what is transduction?
activation of nociceptors by stimuli
30
what is transmission?
conduction of pain message to dorsal part of spinal cord
31
what is modulation?
changing pain perception (non-pharmacological interventions can promote the release of endogenous opioids during this stage- perception of pain changes)
32
what are endogenous opioids?
pain relief from your own body not ingested
33
what is a nociceptor?
a nerve receptor that transmits pain located at the ends of small afferent neurons
34
what are nociceptors stimulated by?
direct cell damage
35
how is nociceptive pain described?
as aching or throbbing
36
what type of pain responds to non opioid and opioid analgesics
nociceptive pain
37
what are the two types of nociceptor fiber types?
C fiber non-myelinated (slow) A-delta myelinated (fast)
38
what type of pain do C fibers transmit? What is an example?
dull, aching, burning pain slow onset, longer duration ex: bump knee
39
what is the "gate theory" of pain?
gate is opened by nociceptor input, anxiety, worry, concentrating on pain gate is closed by non-nociceptor input, positive mood, concentrating on other than pain
39
what type of pain to A-delta fibers transmit? what is an example?
sharp localized pain short duration ex: paper cut
40
what are six factors that influence pain?
1. emotions 2. experience with pain 3. developmental stage 4. sociocultural factors 5. communication skills 6. cognitive impairments
41
when asessing pain it is important to obtain a __________ pain history including ___________, ____________, and_____________.
complete onset location aggravating/alleviating factors
42
what are some nonverbal signs of pain?
elevated pulse/ BP crying, moaning sweating shaking grimacing guarding silence
43
what are the 6 pain scales?
1. numeric rating scale (NRS) 2. vusual analogue scale (VAS) 3. wong-baker faces pain scale 4. PAINAD 5. FLACC behavioral (kids) 6. neonatal infant pain scale
44
what scale is used for normal adults?
numeric rating scale
45
what pain scale is used for children?
wong-baker faces scale FLACC (behavioral pain scale) kids <7
46
what scale is used for people with dementia?
PAINAD
47
what scale is used for infants?
neonatal infant pain scale
48
what is a visual analog pain scale?
a tool that help pt. mark their pain on a continuum (line) from no pain to worst pain shown above faces scale usually
49
FACES is a _______________ pain scale
self-report. the pt. is telling YOU. used on 3+ kids able to say "i am here"
50
what are the 4 types of non-pharmacological pain management methods?
1. cutaneous stimulation 2. immobilization 3. cognitive-behavioral interventions 4. oral sucrose
51
what is oral sucrose used for?
babies in pain
52
what are some cognitive-behavioral interventions?
distraction (music) sequential muscle relaxation guided imagery hypnosis animal therapy therapeutic touch
53
what are some example of cutaneous stimulation for pain management?
-transcutaneous electrical nerve stimulation (TENS) -spinal cord stimulator (SCS) - acupuncture -acupressure -massage -use of hot and cold -contralateral stimulation
54
what types of cutaneous stimulation is the nurse able to do?
massage use of heat and cold contralateral stimulation
55
who uses transcutaneous electrical nerve stimulation (TENS)?
chiropractors physical therapist people in labor
56
what do CAM promote the release of?
endogenous opioids (endorphins and enkephalins)
57
what are some pharmacological measures for pain management?
non-opioid analgesics adjuvant analgesics opioid analgesics
58
give an example of non opioid analgesics?
NSAIDs acetaminophen
59
give an example of opioid analgesics?
(IV, transdermal and epidural forms) nerve block local or topical anesthesia epidural injection
