NSG 1400 Exam 3 with answers
|\ |\ |\ |\ |\
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
|\ |\ |\ |\ |\ |\
