When advising an obese patient about ways to prevent coronary artery disease (CAD),
the nurse suggests using tofu instead of chicken when making food dishes. Which
reason led the nurse to make this suggestion? Select all that apply.
Tofu has a high salt content.
Tofu has very low fiber content.
Tofu is a good source of alpha-linolenic acid.
Tofu increases the triglyceride levels in the body.
Tofu increases omega-3 fatty acid levels in the body. - correct answer Tofu is a good
source of alpha-linolenic acid.
Tofu increases omega-3 fatty acid levels in the body.
The American Heart Association recommends consuming tofu and other soybean
products because they are rich sources of alpha-linolenic acid. Alpha-linolenic acid is
converted to omega-3 fatty acids, which reduce the risk of coronary artery disease by
lowering the triglyceride levels in the body. A diet high in salt may increase blood
pressure, which could make an individual more susceptible to developing coronary
artery disease. A high-fiber diet is preferred to prevent coronary artery disease because
fiber is known to reduce total cholesterol and low-density lipoprotein levels. Increased
triglyceride levels make an individual more susceptible to atherosclerosis.

,A nurse assesses a patient whose angiogram revealed an 80% blockage of the left
circumflex artery and 70% blockage of the right coronary artery. The patient does not
show any symptoms of coronary ischemia. What is the most likely reason for this
finding?
Formation of collateral circulation
Increased production of C-reactive proteins in the liver
Pulmonary artery supplies oxygenated blood to the heart
Lowering of low-density lipoprotein (LDL) levels in the body - correct answer Formation
of collateral circulation
Collateral circulation develops as an inherited predisposition to develop new blood
vessels or in the presence of chronic ischemia. With sufficient collateral circulation, the
heart may still receive an adequate amount of blood and oxygen; therefore the patient is
asymptomatic. Lowering LDL levels does not prevent coronary ischemia in the patient
whose myocardial blood supply is already compromised. The pulmonary artery consists
of deoxygenated blood and does not supply blood to the coronary arteries unless there
is a congenital anatomic variation. C-reactive proteins are inflammatory markers that
are increased in patients with coronary artery disease. These are not associated with
reducing coronary ischemia.
p. 703
Which drug reduces triglycerides by decreasing the hepatic synthesis and secretion of
very-low-density lipoproteins (VLDL)?
Niacin
Fluvastatin
,Gemfibrozil
Cholestyramine - correct answer Gemfibrozil
decreases the hepatic synthesis and secretion of VLDLs, which reduces the levels of
triglycerides. Niacin inhibits the synthesis of VLDLs and low-density lipoproteins (LDL).
Fluvastatin blocks the synthesis of cholesterol and increases the LDL receptors in the
liver. Cholestyramine binds with the bile acids in the intestines, forming an insoluble
complex. The binding results in the removal of LDL and cholesterol.
p. 711
nurse is providing care to a patient with chronic stable angina that is scheduled for a
cardiac catheterization. What finding associated with myocardial ischemia could be
obtained by this diagnostic procedure?
ST segment depression
Cardiac enlargement
Abnormal cardiac wall motion
70% block in right coronary artery - correct answer 70% block in right coronary artery
Cardiac catheterization is an invasive diagnostic procedure to find out the location and
severity of blockages in the coronary circulation. ST segment depression is an important
diagnostic finding for the presence of myocardial ischemia, which is obtained by
electrocardiography (ECG). Cardiac enlargement is a sign of heart failure that can be
seen on an x-ray. Echocardiography is used to detect the presence of abnormal wall
motion due to myocardial ischemia.
, p. 717
A patient that takes digoxin daily is being treated for hyperlipidemia. The nurse should
question a prescription for what lipid-lowering drug that the patient is scheduled to take?
Niacin
Icosapent
Atorvastatin
Cholestyramine - correct answer Cholestyramine
Fibric acid derivatives, such as cholestyramine, interfere with the absorption of many
drugs including digoxin. Icosapent ethyl is an omega-3 fatty acid. Niacin is in the broad
category name of niacin. Atorvastatin is an HMG-CaA reductase inhibitor (statin).
p. 711
Which individuals would the nurse identify as having the highest risk for coronary artery
disease (CAD)?
A 45-year-old depressed male with a high-stress job
A 60-year-old male with below-normal homocysteine levels
A 54-year-old female vegetarian with elevated high-density lipoprotein (HDL) levels
A 62-year-old female who has a sedentary lifestyle and body mass index (BMI) of 23
kg/m 2 - correct answer A 45-year-old depressed male with a high-stress job
