Exam #1 Flashcards
(194 cards)
pain
- whatever the patient experiencing the pain says it is
- pain with someone who has dementia can be experienced as aggitation
- comotose and metnally disabled pts can feel pain just the same
- pain clinics and pain teams in hospitals assigned to deal specifically with pain
why is pain undertreated?
- physicians have: inadequate knowledge in assessment, unwilling to believe pts, lack of time, may think pain management can cause death, inadequate info about addiciton
- pts might not report pain due to: fear of addiction, fear of side effects, belief that pain means they are getting worse, desire to be a “good pt”
pain mechanisms
- nociception: physiologic process by which info about tissue damage is communicated to CNS
1 transduction
2. transmission
3. perception
4. modulation - acute, unrelieved pain leads to chronic pain
- pts can develop adaptive and maladapative mechanisms for dealing with pain (behavioral, addiciton)
how does pain affect pts?
- pysiologic: prolonged stress response, increased HR, increased BP, increase o2 demand, decreased GI motility, immobility, decreased immune response, delayed healing, increased risk for chronic pain
- quality of life: interferes with ADLs, causes anxiety, depression, fear, anger, poor sleep, impairs relationships
- financially: very expensive (lost income, medications, hospitalizations)
Acute pain
- diminishes as healing occurs; responds well to analgesics
chronic pain
- lasts longer than 3 months, nerves may become oversensitive and react to even a slight stimulus
neuropathic pain
- c/b(?) damage to CNS or PNS; not well-controlled by opiods alone, needs adjuvant therapy
- shingles, diabetic neuropathy
- gabapentin, lyrica
- numbing, shooting, stabbing, sharp, electric shock like, burning
tolerance
- body adapts so that exposure to a drug causes changes that result in a decrease in one or more of the drug’s effects
physical dependence
- symptoms c/b abrupt cessation, rapid dose reduction, decreased blood level, and/or administration of an antagonist
addiction
- primary, chronic, neurobiologic disease with genetic, psychosocial and environmental factors
pain assessment
- 5th vital sign
- must assess in a mutlidimensional way
- document the specific words the patient uses
- pattern: onset, duration
- location: local, generalized, referred, radiating
- describe the site, point to the site, drawon on body map, describe every location
- intensity
- quality
- associated symptms
- management strategies
- impact
- DOCUMENT and REASSESS every 30-60 minutes
paint nursing diagnosis
- asses an ‘acceptable’ level of pain for your patient
- don’t plan to make the pain go away all together
- “decrease in pain within one hour of nursing intervention”
OLDCARD & PQRST
- onset, location, duration, characteristics, aggrivating factors, relieveing factors, treatment
- provoke, quality, radiate, severity, time
basic principles of pain treatment
1) follow the principles of pain assessment
2) evert pt deserves adequate pain management
3) base the tx plan on the pt goals (acceptable level according to pt)
4) use both drug and nondrug therapies
5) when appropriate, use a multimodal approach to analgesic thearpy
6) address pain using mutidisciplinary appraoch
7) evaluation the effectiveness of all therapies to ensure they are meeting the pt goals
8) prevent and/or manage med side effects
9) incorporate pt/caregiver teaching throughout assessment and treatment
* administer PRN pain meds “PER DR ORDER”
Drug Therapy for Pain
- non-opiods: mild pain; IBprofen, tylenol, naproxin
- opioid with tylenol: moderate pain
- opioid: moderate to severe pain; morphine; must be on a stool softener 2x day
- adjuvant: neuropathic pain and moderate pain
- treatment can be more effective using meds from more than one group - nonstepor w opiod can help with diff types of pain (bone, cancer)
- “drug ceiling”: drug no longer has an effect after a certain dose
non-opiods for pain
- NSAIDs, acetomenophen, aspirin, tylenol
- NSAIDs, acetomenphehn, aspirin
1) have analgesic ceiling
2) do not produce tolerance or dependence
3) available OTC (most) - mild to moderate pain
- used with opioids to allow for lower opioid levels “opioid sparing effect”
types of Opioids
- work by modifying pain perception
- agonists, and agonist-antagonists
- AVOID giving: darvon and demerol (produce toxic metabolite causeing seizures; DO NOT give to 65+)
- bind to receptors in the CNS and cause 1) inhibition of the transmission of nociceptive input from the periphery to the spinal cord 2) altered limbic system activity 3) activation of the descending inhibitory pathways that modulate transmission in spinal cord
- act on NOCICEPTIVE processes
Opioids for pain
- use for moderate to severe pain; breakthrough pain
- only need one b/c they are all very similar pharmacologically
- can be given by any route - prefer oral route unless pain is severe or need dose titration
- use an equianalgesic chart when changing from IV to oral (conversion chart)
codeine
- weak opioid
- requires an enzyme to break it down to work
- not good for severe pain
- use with a stool softener
hydrocodone
- opioid
- always combined with tylenol or Ibuprofen (lortab, vicodin, vicoprogen) so dose limited
Oxycodone
- opioid- single or combined
- oxycontin is long acting
morphine
- gold standard opioid
- roxanol, avinza, MS contin = long acting
- drug of choice for the elderly, can be given in small doses
hydromorphone
- opioid
- dilaudid
- 8x more potent than morphine
- only short acting
fentanyl (duragesic)
- 72 hour patch (duragesic)
- oral losange (actiq, lollypop)
- not for the opioid-naive
