(Increased BP = Bleeding = not good) ○ antiplatelet (aspirin), use of fibrinolytic (to break clot) ○ Without immediate intervention, ischemia and necrosis will result within hours. The nurse should first wrap the leg to maintain warmth and protect it from further injury. The leg should not be elevated above heart level because doing so would worsen the tissue ischemia. The nurse should quickly notify the physician after taking an action that will benefit the client’s status. Passive range of motion will increase ischemia by increasing tissue demand for oxygen. -If pt comes in with pulselessness and pain, start heparin and monitor PTT Exam 2 Review-finished. GRADED A 27) Assessment for peripheral arterial occlusion S/S = 6 P’s i) pain (w/activity and rest)⇒ paresthesia (numb and cold)-early s/s ii) pallor (pale skin)⇒ poikilothermy (coolness) (1) poikilocythemia (irregular shaped RBC, abnormal variance in shape) iii) pulselessness ⇒paralysis -Intermittent claudication : caused by too little blood flow, usually during exercise ○ Surgical treatment called thrombectomy or embolectomy under local anesthesia to remove occlusion via catheter and possible patch graft. ○ PAD-Avoid tight stockings – constrict veins, lower affected extremity ○ PVD – encourage tight stockings, and elevate to allow blood flow to the heart -Define: arteries of the lower extremities and is characterized by inadequate flow of blood resulting from atherosclerosis (thickening of the intima and media of the arteries causing narrowing) - Assessment: - Burning, cramping, pain, numbness in legs when exercising, in bed, or in dependent position - bruit over femoral and aortic arteries, decreased capillary refill, decreased palpable pulses,dry skin, thick toenails, cold extremities, pallor extremities when elevated, dependent rubor (redness), muscle atrophy, ulcers, gangrene -Patient teaching - No crossing of the legs, no raising legs above heart, wear loose clothes, discourage smoking, no cold temperatures, educate about foot care (keep them clean, dry, wear good fitting shoes, never go barefoot, cut toenails across, or go to the podiatrist), teach relaxation techniques because stress increases vasoconstriction 28) Treatment for bleeding w/coumadin and w/heparin ○ treatment for bleeding with coumadin is vitamin K ○ heparin: protamine sulfate is the heparin antagonist used for excessive bleeding i) - 1-1.5 mg per 100U of heparin, do not exceed 50 mg within 60-90 minutes of heparin administration 29) Risk factors for varicose veins (incompetent valves leads to venous congestion and decreased venous blood return) ○ standing for long periods of time, genetics, hormonal changes, increase blood volume. ○ hereditary, pregnancy ○ avoid strenuous physical activity, avoid constrictive clothing, and increase in exercise (walking and swimming), weight reduction plan for obese, don’t cross legs, use compression stockings no occlusive stockings-impedes blood flow) Hypertension Exam 2 Review-finished. GRADED A 30) Teaching for HTN ○ lifelong management, how to check blood pressure at home, diet teaching, exercise. ○ will always have the diagnosis 31) Know what smoking does in relation to HTN ○ smoking thins vessels and causes vasoconstriction. This causes blood pressure to increase, increases heart rate, narrows the blood vessels, decreases elasticity. ○ 32) HTN manifestations ○ headaches (especially in morning), , flushing, ask if the pt. is a smoker, fatigue, chest pain, difficulty breathing. ○ usually asymptomatic, may cause HA particularly in the AM, dizziness, blurred vision, fainting, retinal changes, visual disturbances, nocturia. Most patients with prolonged high BP will have c/o of HA nurse should assess this while gathering information from the client. ○ 33) HTN stages and what the values of BP are ○ JNC7: Normal <120/<80, ○ Prehypertension: at risk, 120-139/80-89, ○ Stage 1 Hypertension 140-159/90-99, ○ Stage 2 Hypertension >159/>99 ** for exam, focus on preHTN stage, answer is 130-140 34) Exercise and HTN ○ exercise can lower blood pressure by 5-10 mmHg ○ Regular exercise makes the heart stronger, allowing it to pump blood with less effort, which reduces the force exerted on the artery walls and helps with weight loss. In addition to helping control blood pressure, regular exercise reduces the risk of MI, cerebrovascular accident (stroke), high cholesterol, diabetes, osteoporosis, and some cancers. 35) Modifiable and nonmodifiable risk factors for primary HTN ○ Non-modifiable risk factors: family history, gender men > women, age, race, genetics. ○ Modifiable risk factors: stress, obesity, high dietary intake of sodium or saturated fats, excessive caffeine, alcohol, or cigarette smoking. And oral contraceptives use use (Estrogen and progesterone – combo pills). ○ Secondary HTN: Renal Vascular diseases, Coarctation of aorta, primary hyperaldosteronism, hyperthyroidism, meds such as estrogens, and antidepressants, NSAIDs, and steroids. Interventions: · DASH diet = low fat & cholesterol - high grains, fruits & vegetables is rich in grains, fruits, vegetables, and low-fat dairy products, fiber, potassium, calcium, and magnesium - limits fat, saturated fat, and cholesterol. Reduction in blood pressure of 8–14 mm Hg in patients with hypertension who follow the DASH diet. · Avoid high sodium = canned foods, animal products (Keep sodium under 2400 mg)
