Why is HDL considered good cholesterol? - (answer)It's able to remove
cholesterol from artery plaques and recycle it back to the liver.
Why is HDL consider good cholesterol - (answer)HDL is considered good
cholesterol because it collects excess cholesterol in the body cells and
transports it to the liver where it is excreted. HDL carries 20 to 25% of total
plasma cholesterol.
Explain the role inflammation has in the development of atherosclerosis -
(answer)Inflammation in the heart muscle caused by chronic inflammatory
processes leads to mitochondrial damage that results in an increased free
radical production that further activates the chronic inflammatory vicious cycle
Explain the role inflammation has in the development of atherosclerosis -
(answer)Activated mast cells recruit inflammatory cells that provoke plaque
formation and lead to atherosclerosis. Chronic inflammatory infiltrates occupy
layers of arteries were stable plaques are formed and associated with
atherosclerosis.
Explain the role inflammation has in the development of atherosclerosis -
(answer)Additionally active inflammation involves a thinning at the fibrous Of
atherosclerotic plaque which predisposes vulnerable plaque to rupture.
Why does the APRN recognize as the result of the pleural friction rub? -
(answer)The inflammation of the pericardium due to either the underlying
autoimmune disease or a post viral syndrome causes roughening of the
pericardium. This causes the classic rug which can be best heard at the Apex of
the heart and left sternal border.

Explain how a positive strep test has caused the patient's symptoms -
(answer)Rheumatic heart disease RHD only develops after a pharyngeal
infection with group a beta hemolytic streptococcus. It is an abnormal
response to humoral and cell mediated response to M proteins. Inflammation
causes proliferative and exudative lesions in connective tissue.
Explain how a positive strep test has caused the patient's symptoms -
(answer)Inflammation causes scarring of the valve tissue. Inflammation usually
affects the endocardium which contains the valves. Endocardial inflammation
causes swelling of leaflets in the valves.
Describe the factors that could have contributed to the development of a DVT
in this patient and explain how each of the factors could cause DVT -
(answer)Virchow's Triad caused damage to the walls of the vessels. Injury to
the intimal layer of the vessel, antiplatelet substances such as nitric oxide and
prostacyclin, along with the expression of collagen on the vessel wall, causes
adherence to the platelets to the vessel wall.
Describe the factors that could have contributed to the development of a DVT
in this patient and explain how each of the factors could cause DVT -
(answer)Platelets become activated, then aggregate, forming clots. Venous
stasis is a result of obesity, patients advanced age, and inability to perform
physical therapy therapy.
Explain why large pulmonary embolus interferes with oxygenation -
(answer)The embolus lodges somewhere in the pulmonary circulation and
causes a ventilation/perfusion mismatch V/Q. Ventilation perfusion mismatch
or V/Q defects are defects in total long ventilation perfusion ratio.
Explain why large pulmonary embolus interferes with oxygenation - (answer)It
is a condition in which one or more areas of the lung receive oxygen but no
blood flow, or they receive blood flow but no oxygen due to obstruction
, 3
somewhere in the pulmonary circulation. This causes a decreased area for
oxygen exchange.
Explain why a large pulmonary embolism causes right ventricular strain -
(answer)The V/Q mismatch causes release of neurohumeral substances and
inflammatory mediators that cause vasoconstriction of the pulmonary
vasculature further impeding oxygenation.
Explain why a large pulmonary embolism causes right ventricular strain -
(answer)Hemodynamically this vasoconstriction results in pulmonary
hypertension, making it difficult for the right ventricle to pump blood.
Explain why a large pulmonary embolism causes right ventricular strain -
(answer)The V/Q mismatch also creates decreased production of surfactant
causing atelectasis that further decreases surface area available for oxygen
exchange.
Explain early asthmatic responses in the cells responsible for the responses -
(answer)When there is an initial airway exposure to an antigen, an innate and
adaptive immune response is initiated.
Explain early asthmatic responses in the cells responsible for the responses -
(answer)Cells that can initiate the inflammation of the bronchial mucosa and
hyperresonance of the airways include Dedrick cells, T-helper 2 cells,
lymphocytes, B lymphocytes, mast cells, neutrophils, eosinophils, and
basophils.
Explain early asthmatic responses in the cells responsible for the responses -
(answer)Early asthmatic response is a phase of bronchospasm that peaks at
about 30 minutes and usually resolves after about 3 hours.
