NURS 6501 MODULES 1-4 EXAM
Questions and Answers (Verified Answers)
1. Why is HDL considered good cholesterol?
Answer It's able to remove cholesterol from artery plaques and
recycle it back to the liver.
2. 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.
3. 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
4. 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.
5. 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.
6. 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.
,7. 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.
8. Explain how a positive strep test has caused the patient's symptoms
Answer In- flammation causes scarring of the valve tissue.
Inflammation usually affects the endocardium which contains the
valves. Endocardial inflammation causes swelling of leaflets in the
valves.
9. 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.
10. 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.
11.Explain why large pulmonary embolus interferes with oxygenation
Answer The embolus lodges somewhere in the pulmonary circulation
and causes a ventila- tion/perfusion mismatch V/Q. Ventilation
perfusion mismatch or V/Q defects are defects in total long
ventilation perfusion ratio.

Answer It is
