|\ |\ |\ |\ |\




Impaired Central Perfusion - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\



✔✔Caused by inadequate cardiac output, which leads to
|\ |\ |\ |\ |\ |\ |\ |\



reduction in oxygenated blood reaching the body tissue
|\ |\ |\ |\ |\ |\ |\ |\



(systemic effect). This can lead to ischemia, cell injury or
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



death if untreated.
|\ |\




Impaired Local (Tissue) Perfusion - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\



✔✔Associated with loss of vessel patency or permeability, |\ |\ |\ |\ |\ |\ |\



or inadequate central perfusion. Results in impaired
|\ |\ |\ |\ |\ |\ |\ |\



blood flow to the body tissue (localized effect). Leads to
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



ischemia and if untreated, will lead to cell death.
|\ |\ |\ |\ |\ |\ |\ |\




Risk Factors for Perfusion - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\



✔✔Middle-aged and older adults |\ |\ |\




Men
African Americans |\




Inadequate Perfusion in Infants - CORRECT ANSWERS |\ |\ |\ |\ |\ |\ |\



✔✔Signs/Symptoms:
Poor feeding, poor weight gain, failure to thrive
|\ |\ |\ |\ |\ |\ |\

,Inadequate Perfusion in Toddlers/Children - CORRECT
|\ |\ |\ |\ |\ |\



ANSWERS ✔✔Signs/Symptoms: |\




Squatting and fatigue, and failure to reach milestones.
|\ |\ |\ |\ |\ |\ |\




Serum Lipid Levels (Perfusion) - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\



✔✔Total lipids: 400-1,000 mg/dL
|\ |\ |\




Cholesterol: <200 mg/dL |\ |\




Triglycerides: Male- 40-160 mg/dL |\ |\ |\




|\ Female- 135-145 mg/dL |\ |\




HDL: F- >55mg/dL
|\ |\




|\ M- >45 mg/dL
|\ |\




LDL: <130mg/dL
|\




Elevations of lipids indicate CAD. |\ |\ |\ |\




Platelets (Perfusion) - CORRECT ANSWERS ✔✔150,000-
|\ |\ |\ |\ |\



400,000 cells/mm3 |\




Essential for blood clotting |\ |\ |\




<100,000 tends to indicate thrombocytopenia.
|\ |\ |\ |\




>400,000 tends to indicate thrombocytosis.
|\ |\ |\ |\




Prothrombin Time - CORRECT ANSWERS ✔✔Measures |\ |\ |\ |\ |\ |\



clotting factors ability.
|\ |\




11-12.5 seconds |\

, INR - CORRECT ANSWERS ✔✔0.8-1.1
|\ |\ |\ |\ |\




International Normalized Ratio |\ |\




Coagulation blood test |\ |\




aPTT - CORRECT ANSWERS ✔✔>30-40 seconds
|\ |\ |\ |\ |\




PTT - CORRECT ANSWERS ✔✔60-70 seconds
|\ |\ |\ |\ |\




EKG - CORRECT ANSWERS ✔✔Measures heart rhythm
|\ |\ |\ |\ |\ |\ |\



wave deflections and heart rate
|\ |\ |\ |\




Cardiac Stress Test - CORRECT ANSWERS ✔✔Can use
|\ |\ |\ |\ |\ |\ |\ |\



chemical or exercise. |\ |\




Monitor heart under increased stress.
|\ |\ |\ |\




Normal findings should show no change in electrical
|\ |\ |\ |\ |\ |\ |\ |\



conduction and person should not have chest pain.
|\ |\ |\ |\ |\ |\ |\




Electrolytes (Perfusion) - CORRECT ANSWERS |\ |\ |\ |\ |\



✔✔Potassium: Profound effects on HR & contractility. |\ |\ |\ |\ |\ |\




Calcium: High levels can cause dysrythmias.
|\ |\ |\ |\ |\




Magnesium: High levels slow down cardiac conduction. |\ |\ |\ |\ |\ |\




Low levels increase cardiac irritability and arrthymias
