154 exam 2
| Term | Definition |
|---|---|
| analgesics | medications that relieve pain without causing loss of consciousness |
| pain | whatever the patient says it is and occurs whenever they say it does |
| pain threshold | the level of stimulus needed to produce a painful sensation |
| pain tolerance | the patient's ability to tolerate or stand the pain; influenced by age, diseases, culture, previous experience |
| acute pain | sudden onset, usually localized with limited duration; increased hemodynamics, sweating, pallor |
| chronic pain | persistent or recurring pain lasting longer than 6 weeks; much more difficult to treat |
| somatic pain | originate from skeletal muscles, ligaments and joints; responds best to NSAIDs or nonopiates |
| superficial pain | originates from skin and mucous membranes; skinned knee, dental pain |
| visceral pain | originates from organs or smooth muscles; appendicitis, MI, gallbladder attack |
| vascular pain | originates from vascular or perivascular tissues; migraines |
| referred pain | pain is experienced in a place other than the point of origin; heart attack -> pain in left arm |
| Gate Theory | When gates are open, pain impulses are allowed through and the brain perceives pain; when gates are closed, impulses are stopped and perception is altered |
| A fibers | larger diameter fibers that conduct sharp and localized pain impulses; associated with acute pain |
| C fibers | small diameter fibers that slowly conduct dull and nonlocalized pain impulses; associated with chronic pain |
| pain control | The ultimate goal when addressing pain with a patient |
| Step 1 | the use of nonopioids with or without adjuvant medications once the pain has been identified and assessed |
| Step 2 | the use of opioids with or without nonopioids and with or without adjuvant medications |
| Step 3 | the use of opiods indicated for moderate to sever pain, administered with or without nonopioids or adjuvant medications |
| opioids | drugs that bind to opiate receptors to relieve pain |
| alter | Opiates ______ the perception of pain and do nothing to cure or heal what is causing the pain. |
| remove | You must ______ the old patch first. |
| Narcan | antidote for opiate overdosage; opiate antagonist; also reverses pain relief |
| opioid tolerant | patient has been receiving opiates for extended period of time and requires higher doses to control pain at same level |
| withdrawal symptoms | n/v/d, chills, mental agitation, tachycardia, increased BP, diaphoresis, runny nose, cramps |
| opiate naive | patients are not accustomed to taking opiates and require smaller dosages to relieve their pain |
| respiratory depression | Most serious adverse effect of opiates (think ABC) |
| histamine | All opiates cause the release of ______, which can lead to redness and itching. |
| Change positions slowly. Siderails should be up, call light within reach. | Because histamine causes vasodilation -> orthostatic hypotension, what precautions should be in place? |
| liver | Opiates may cause an increase in ______ enzymes, which means the nurse should assess them. |
| NSAIDs | work by suppressing some part of the inflammatory process and reduces the amounts of pain-mediating chemicals |
| stomach | NSAIDs are very hard on the _____ and you must assess for increased bleeding, abdominal pain |
| coontraindicated | NSAIDs are ___________ in patients with history of GI bleed, ulcers, anticoagulatnt/antiplatelet, renal problems |
| reduce blood flow | All NSAIDs except aspirin _____ _____ ____ to the kidneys |
| hepatotoxic | Tylenol is extremely _______ with acute overdose |
| acetylcysteine (Mucomyst) | treatment for Tylenol overdose; smells like rotten eggs, mix with juice and give with straw |
| LFTs | Examples: AST, ALT, alk. phos. |
| sedatives | reduce nervousness, excitability, and irritability without causing sleep |
| hypnotics | cause sleep and have a much more potent effect on the CNS |
| sedative-hypnotics | drugs that can act in the body as a sedative or a hypnotic |
| 3 | How many groups of sedative-hypnotics are there? |
| barbiturates | a class of drugs used to induce sedation; highly habit forming and narrow therapeutic window; NO antidote |
| ital | common ending of barbiturates |
| REM | Barbiturates deprive people of _____ sleep. |

| benzodiazepines | drugs most frequently prescribed as anxiolytic drugs |
| pam, lam | common endings for benzodiazepines |
| flumazenil (Romazicon) | benzo antidote used in extreme cases |
| muscle relaxers | used for the relief of skeletal muscle spasticity; relieve pain |
| Flexeril (cyclobenzaprine) | highly sedating; must watch for altered sensorium; high fall risk; take at bedtime |
| Lioresal (baclofen) | given to relieve extreme spasms in paraplegia and quadriplegia |
| Dantrium (dantrolene) | used for acute management of malignant hyperthermia; can cause liver problems |
| malignant hyperthermia | genetic predisposition when patients receive anesthesia; uncontrolled shivering, extreme increase in temp |
| drive | Cannot _____ when taking a muscle relaxer |
| CNS stimulants | drugs that stimulate specific areas of the brain or spinal cord |
| ADHD | symptoms of inability to maintain attention span, presence of hyperactivity must be present for greater than 6 months and occur in 2 different settings |
| narcolepsy | syndrome characterized by sudden sleep attacks, cataplexy, sleep paralysis, and visual or auditory hallucinations at the onset of sleep |
| amphetamines | drugs used to treat ADHD and narcolepsy |
