Impaired Central Perfusion - correct answer ✔✔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 answer ✔✔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 answer ✔✔Middle-aged and older adults
Men
African Americans
Inadequate Perfusion in Infants - correct answer ✔✔Signs/Symptoms:
Poor feeding, poor weight gain, failure to thrive
Inadequate Perfusion in Toddlers/Children - correct answer ✔✔Signs/Symptoms:
Squatting and fatigue, and failure to reach milestones.
Serum Lipid Levels (Perfusion) - correct answer ✔✔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 answer ✔✔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 answer ✔✔Measures clotting factors ability.
11-12.5 seconds
INR - correct answer ✔✔0.8-1.1
International Normalized Ratio
Coagulation blood test
aPTT - correct answer ✔✔>30-40 seconds
PTT - correct answer ✔✔60-70 seconds
EKG - correct answer ✔✔Measures heart rhythm wave deflections and heart rate
Cardiac Stress Test - correct answer ✔✔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.
