A patient with atherosclerosis asks the nurse to describe the events leading to the development of the
atherosclerosis. In which order does the nurse describe the pathophysiological events? - correct answer
✔✔1. "Chronic injury led to the damage of your endothelium, or cells lining your blood vessels."
2. "Lipids were able to access and accumulate in the smooth muscle cells of the blood vessels."
3. "The blood vessel narrowed due to accumulation of fibrous protein."
4. "A build-up of collagen resulted in a partial or total blockage of your blood vessels."
Chronic endothelial injury results in damage to the endothelium. This leads to a buildup of lipids in the
smooth muscle cells, or a fatty streak. Collagen covers the fatty streak, leading to a partial occlusion of
the blood vessels. A rupture of the fibrous plaque results in a thrombus, and potentially, total occlusion
of the vessel.
The nurse would use which statement to describe to the patient with coronary artery disease (CAD) how
fatty streaks are formed?
"Damaged arteries allow platelets to form a thrombus."
"Damaged arteries allow lipids to be deposited in the intima."
"Infections cause bacteria to move inside the artery wall."
"Increased cholesterol intake directly causes plaque formation." - correct answer ✔✔"Damaged arteries
allow lipids to be deposited in the intima."
Damaged arteries allow lipids to be deposited in the inside of the artery to form fatty streaks, beginning
the process of atherosclerosis.
, The formation of a thrombus is not due directly to damaged arteries, but occurs after a plaque has
established and ruptured. Although bacterial infections are one of the processes that irritate the
endothelial lining, bacteria do not move inside the artery wall. Plaque formation occurs after the walls of
the artery are damaged and lipids are deposited in the lining, not as a direct result of increased
cholesterol intake.
Which process would result in the development of myocardial ischemia in a patient with coronary artery
disease (CAD)?
An increase in serum lipids
An increase in collagen fibrils
A decreased oxygen demand or an increased oxygen supply
An increased demand for oxygen or a decreased supply of oxygen - correct answer ✔✔An increased
demand for oxygen or a decreased supply of oxygen
When the demand for myocardial oxygen exceeds the ability of the coronary arteries to supply the heart
with oxygen, myocardial ischemia occurs.
Although lipid deposits may contribute to the development of atherosclerosis, an increase in serum
lipids does not promote the development of myocardial ischemia in a patient with CAD.Although
deposition of collagen may contribute to the development of atherosclerosis, an increase in collagen
fibrils does not promote the development of myocardial ischemia in a patient with CAD.A decreased
oxygen demand or an increased oxygen supply would not cause a lack of oxygen to the coronary arteries
and would not cause myocardial ischemia.
The health care team is caring for a patient with coronary artery disease (CAD) who has hepatitis C. The
patient's triglyceride level is 658 mg/dL. Which drug would the best choice to administer to this patient
initially?
Nitrates
Diuretics
Omega-3 fatty acid
3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) - correct answer
✔✔Omega-3 fatty acid
