NSG 1400 Exam 3 Questions and Answers| New Update with 100% Correct Answers
Impaired Central Perfusion 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 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 Middle-aged and older adults
Men
African Americans
Inadequate Perfusion in Infants Signs/Symptoms:
Poor feeding, poor weight gain, failure to thrive
Inadequate Perfusion in Toddlers/Children Signs/Symptoms:
Squatting and fatigue, and failure to reach milestones.
Serum Lipid Levels (Perfusion) 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) 150,000-400,000 cells/mm3
Essential for blood clotting
<100,000 tends to indicate thrombocytopenia.
>400,000 tends to indicate thrombocytosis.
Prothrombin Time Measures clotting factors ability.
11-12.5 seconds
INR 0.8-1.1
International Normalized Ratio
Coagulation blood test
aPTT >30-40 seconds
PTT 60-70 seconds
EKG Measures heart rhythm wave deflections and heart rate
Cardiac Stress Test 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) 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
