  • Therapy= pericardiocentesis (aspirator pericardial fluid)
  • Complications= cardiac tamponade Ch. 35 Peripheral Vascular Diseases*
  • PAD= lower extremities inadequate flow of blood, caused by atherosclerosis o Risks= htn, hyperlipidemia, dm, smoking, obesity, sedentary o Findings= burning, cramping, pain in the legs during exercise (intermittent claudication), pain that’s relieved by placing legs at rest in dependent position, decreased cap refill, decreased pulse, loss of hair on lower calf, dry scaly mottle skin, thick toenails, pallor of extremity with elevation, dependent rubor, ulcers and gangrene of toes o Care= exercise to build up, walk to point of pain stop and rest and then walk a little farther, provide warm environment and wear insulated socks, avoid stress, caffeine, nicotine, avoid crossing legs, refrain from wearing restrictive garments o Meds § Antiplatelet= clopidogrel, aspirin, reduce blood viscosity, increase blood flow o Procedure= balloon and stent to open and help maintain patency of vessel, laser assisted angioplasty, vaporize atherosclerotic plaque and open artery, bypass graft to reroute circulation around arterial occlusion § Monitor vitals, peripheral pulse, cap refill, keep on bed rest with limb straight for 2-6hr b/f ambulation § Mark location of pedal and dorsalis pulse, monitor bp, hypotension can result in increased risk of clotting or graft collapse, htn increases risk of bleeding o Complications § Graft occlusion= absent or reduced pedal pulses, increased pain or change in extremity color or temp § Compartment syndrome= tingling, numbness, worse pain, edema, pain on passive movement
  • PVD o VTE= blood clot form as result of venous stasis § Risks= Virchow triad (hypercoagulability, impaired blood flow, damage to blood vessels), hip surgery, total knee replacement, heart failure, immobility, pregnancy, ocp § Findings= calf or groin pain, tender, sudden onset of edema, warmth, induration and hardness over involved blood vessel, SOB and chest pain (PE) § Diagnostic= venous duplex ultrasonography

§ Care= elevation of extremity above level of heart but avoid using knee gatch or pillow, warm moist compress, do NOT massage, thigh high compression or antiembolism stocking § Meds

  • Heparin= prevent formation of other clots and enlargement of existing clots (monitor aptt and platelet count, have protamine (antidote)
  • Low molecular wt heparin
  • Warfarin= therapeutic effect takes 3-4 days to develop, monitor pt and inr, have vitamin k (antidote), do NOT fluctuate in diet of green leafy vegetables
  • Thrombolytic therapy= dissolve clots, use electric instead of blade razor and brush teeth with soft toothbrush o Venous insufficiency= incompetent valves in deep veins of lower extremities, venous stasis ulcers § Risks= sitting or standing in one position for long period of time, obesity, pregnancy § Finding= brown discoloration of ankles, edema, stasis ulcers around ankles § Care= elevate leg above heart when in bed, wear stockings after legs have been elevated o Varicose veins= enlarged, twisted superficial veins § Risk=female, older than 30, prolonged standing, pregnant, obesity, family history § Finding= superficial veins § Lab test= Trendelenburg test (supine position with legs elevate) § Therapy= sclerotherapyàchemical solution is injection into varicose vein, vein strippingà removal of large varicose veins that can’t be treated o Lab tests= d dimer test is positive indicate thrombus formation o Findings= aching pain, heaviness Ch. 36 Hypertension*
  • BP >140/90, poorly controlled bp affects heart, brain, eyes, kidneys
  • Risk factors o Primary= family hist, excess na, physical inactivity, obesity, alcohol, black, smoking, hyperlipidemia, stress o Secondary= kidney disease, cushing, pheochromocytoma
  • Findings= asymptomatic, headaches, dizzy, visual disturbances
  • Meds o Diuretics= increase k excretion or k sparing (spironolactone) o Ccb= verapamil, amlodipine, diltiazem; hypotension, constipation, avoid grapefruit o Acei= cough, angioedema o Arb= cause hyperk, angioedema or hf, avoid foods high in k o Aldosterone receptor antagonist= cause hypertriglyceridemia, hypona, hyperk, NO salt substitutes o BB= metoprolol, hypoglycemia, sex dysfunction, fatigue, weakness o Central alpha agonist= clonidine, cause sedation, orthostatic hypotension
