  1. Hyperuricemia
    Gout is a kind of arthritis that occurs when uric acid builds up in the joints.Acute gout is a painful condition that typically affects one joint.Chronic gout is repeated episodes of pain and inflammation, which may involve more than one joint.
  2. Elevation Pallor
    pallor or blanching of the foot in response to leg elevation
  3. Dependent Rubor
    reactive hyperemia (redness) is observed when limb is hung in a dependent position
  4. Ticlid
    antiplatelet agent; inhibits platelet activation
  5. Trental
    drug for intermittent claudication; increases red blood cell flexibility and reduces blood viscosity which helps blood flow to ischemic muscle
  6. Percutaneous Transluminal Ballon Angioplasty
    involves catheter inserted into femoral artery; advanced to narrowed artery and balloon is inflated; blood vessel dilates and cracks the confining atherosclerotic intimal shell which also stretches the underlying media

    high rate of stenosis; up to 50% at 1 year
  7. Endarterectomy
    opening the artery and removing the obstructing plaque; common with carotid artery
  8. Patch Graft Angioplasty
    opening the artery, removing the plaque and sewing a patch to the opening to widen the lumen
  9. Fem-pop bypass postop
    assess Q15min initially then hourly for changes in color and temp, capillary refill, presence of peripheral pulses distal to operative site, and sensation and movement of the extremity

    Loss of palpable pulses, dramatic increase in pain, extermity pallor or cyanosis, decreasing ABI, numbness or tingling, or cold extremity temp necessitate immediate notification of surgeon
  10. Poikilothermia
    adaptation of the ischemic limb to environmental temperature, most often cool
  11. Buerger's Disease
    rare, nonatherosclerotic, segmental inflamatory disorder of medium-sized veins, arteries and nerves of the upper and lower extermities

    highly cellular and inflammatory thrombus forms inside vessel causing tissue ischemia

    begins with distal vessels progressing to more proximal vessels

    strong relationship between tobacco use and illness; only occurs in smokers; when smoking stops, disease improves

    avoid nicotine replacement products; same vasodilating effects
  12. Raynaud's Phenomenon
    episodic vasospastic disorder of the small cutaneous arteries most frequently involving the fingers and toes

    causes color changes of the fingers, toes, ears and nose (white, blue, and red); decreased perfusion due to arteriole vasospasm results in pallor (white; then digits appear cyanotic (blue) and followed by rubor (red) caused by hyperemic response that occurs when perfusion restored

    client c/o coldness and numbness followed by throbbing, aching pain, tingling and swelling; may last minutes to hours

    brought on by cold, emotional upset, caffeine, tobacco use or vibratory tools

    recommend use of gloves when cold or handle cold objects; avoid temperature extremes; stop smoking; avoid caffeine

    calcium channel blockers (e.g. Procardia, Cardizem) relax smooth muscles of arterioles and reduce the number of vasospastic attacks; side effects: tachycardia, headache, flushing, dizziness, and peripheral edema

  28. Muscle Strength Scale

    • Grade 5: Muscle contracts normally against full resistance.
    • Grade 4: Muscle strength is reduced but muscle contraction can still move joint against resistance.
    • Grade 3: Muscle strength is further reduced such that the joint can be moved only against gravity with the examiner's resistance completely removed. As an example, the elbow can be moved from full extension to full flexion starting with the arm hanging down at the side.
    • Grade 2: Muscle can move only if the resistance of gravity is removed. As an example, the elbow can be fully flexed only if the arm is maintained in a horizontal plane.
    • Grade 1: Only a trace or flicker of movement is seen or felt in the muscle or fasciculations are observed in the muscle.
    • Grade 0: No movement is observed.
