| compartment syndrome, card 1 | compartment syndrome occurs when injured tissue swells within the fascia and connective tissues inside a limb causing an increase in the pressure within that “compartment”. |
| compartment syndrome, card 2 | pressure within the closed fascia “compartment” becomes a tourniquet for the surrounding tissue within the compartment. |

| RA - stage 4 | fibrous or bony ankylosis, stage III criteria |
| RA onset | insidious, fatigue, anorexia, weight loss, generalized stiffness (precipitating events - might be mumps or diabetes 1) |
| RA - affects | symmetrical affects small joints of hands and feet |
| RA - mornings | morning stiffness may last from 60 minutes to several hours or longer |
| RA - finger | may become spindle shaped from synovial hypertrophy and thickening of joint capsule |
| RA - joint pain | increases with motion, varies in intensity, may not be proportional to degree of inflammation |
| RA progression | inflammation and fibrosis of joint capsule & supporting structures may lead to deformity and disability |

| pain -afferent | from site of injury to the brain |
| pain - A-delta fibers | send sharp, localized, distinct sensations |
| pain - unmyelinated C fibers | slow & small. They send poorly localized, burning, persistent pain |
| Gate-control theory | Pain has emotional & cognitive components aside from the physical sensation. Pain impulses pass through when a gate is open and are blocked when a gate is closed. |
| reflex arc | reflex to pain stimulus |
| acute pain | transient, identifiable, short duration, limited emotional response |
| chronic - noncancer | not protective, no purpose, may or may not have an identifiable cause |
| chronic episodic | occurs sporadically over an extended period of time |

| symptoms of chronic pain | fatigue, insomnia, mood changes - irritable, anger/frustration/depression, |
| pain tolerance | the level of pain a person is willing to accept |
| pain management | systematic (regular intervals to keep the pain at manageable levels) |

| A postoperative patient with a PCA | evaluate effectiveness by comparing current assessment with baseline pain |
| monitoring patients using pain medication | check for depressed CNS (over sedation, respiratory depression) |
| activation of large-diameter A fibers | closes gate, inhibits transmission to the brain (TENS, massage, ...) |
| activation of small C fibers | opens the gate and allows the perception of pain |
| PCA by proxy | someone other than the patient pushes the pump |
| adjuvant drugs | NSAIDS, antidepressants, anticonvulsants, corticosteroids (amitriptyline, Gabapentin) |
| opioid - adverse effects | euphoria, CNS depression, nausea/vomiting, urinary retention, diaphoresis and flushing, pupil constriction (miosis), constipation, itching |

| I & O | example: IV = 3000mL in the bag. 1800mL has flowed through tube into pt. 1500mL has been voided. 1800 (in) - 1500 (out) = 300 mL = amount of urine over a 10 hour shift. |
| digestive track | mouth, esophagus, stomach, small intestine, large intestine, anus |
| common bowel problems | constipation, impaction, diarrhea, incontinence, flatulence, hemorrhoids |

| OA indicators | one side (1 knee replaced),weight bearing exercises help, lack of calcium, vertebrae cracks, smoking makes it worse |
| RA indicators | starts at any age, both sides of the body |
| sign of compartment syndrome | lack of a pulse |
| bucks traction | pre-surgical |
| What does hot & cold due? | hot = vasodilation cold = decrease inflammation |
| monitor pt's on PCA and opiods for | change in LOC and decreased respiration. Stop meds and call doc |
| acute pain is | protective, has a cause, short duration, limited tissue damage, emotional response |
| neuropathic pain | treatment usually includes adjuvant analgesics |
