- A.
  
  Thrombus
- B.
  
  Aneurysm
- C.
  
  Embolism
Correct Answer
B. Aneurysm

Explanation
An aneurysm refers to the localized dilation or outpouching of a vessel wall or cardiac chamber. It is a condition where the wall of the blood vessel weakens and bulges, creating a balloon-like appearance. This can occur in any blood vessel in the body, but is most commonly seen in the arteries. Aneurysms can be dangerous as they have the potential to rupture, leading to severe bleeding and potentially life-threatening complications. Therefore, identifying and treating aneurysms is crucial in preventing complications and ensuring the patient's well-being.

A middle aged female comes to the doctor with complaints of a sudden painful, pulsating mass in the midline of her abdomen...upon further assessment, the presence of bruit is confirmed...which of the following conditions is consistent with the findings?
- A.
  
  Aneurysm "Circle of Willis"
- B.
  
  Abdominal aorta aneurysm
- C.
  
  Abdominal aorta thrombus
Correct Answer
B. Abdominal aorta aneurysm

Explanation
The presence of a sudden painful, pulsating mass in the midline of the abdomen, along with the confirmation of a bruit, suggests an abdominal aorta aneurysm. A bruit is a sound caused by turbulent blood flow through a narrowed or abnormal vessel, which is commonly heard in aneurysms. Abdominal aorta aneurysm refers to the abnormal dilation of the abdominal aorta, which can cause a pulsating mass and is often associated with pain. The other options, "Aneurysm Circle of Willis" and "abdominal aorta thrombus," do not fit the given symptoms and findings.

Which of the following disorders would cause signs of intracranial pressure, such as decreased levels of consciousness, bradycardia, widened pulse pressure, small, sluggish pupils?
- A.
  
  Aneurysm- Circle of Willis
- B.
  
  Aneurysm-femoral poplitieal artery
- C.
  
  Thrombus in Cerebral artery
Correct Answer
A. Aneurysm- Circle of Willis

Explanation
An aneurysm in the Circle of Willis, which is a network of blood vessels in the brain, can cause signs of increased intracranial pressure. The increased pressure can lead to decreased levels of consciousness, bradycardia (slow heart rate), widened pulse pressure (difference between systolic and diastolic blood pressure), and small, sluggish pupils. This is because the aneurysm puts pressure on the surrounding brain tissue and impairs blood flow and oxygen supply to the brain.

Aneurysms with symptoms of ischemia are probably located in which of the following areas?
- A.
  
  Abdominal Aorta
- B.
  
  Thoracic Aorta
- C.
  
  Femoral and Popliteal Artery
Correct Answer
C. Femoral and Popliteal Artery

Explanation
Aneurysms with symptoms of ischemia are probably located in the Femoral and Popliteal Artery. Ischemia refers to a lack of blood supply to a particular area, usually due to a blockage or narrowing of the blood vessels. The Femoral and Popliteal Artery are major blood vessels in the leg, responsible for supplying blood to the lower extremities. If an aneurysm occurs in these arteries, it can lead to a reduction in blood flow, causing ischemic symptoms such as pain, numbness, and weakness in the affected leg.

- A.
  
  Doppler untrasonography
- B.
  
  MRI
- C.
  
  Angiography
- D.
  
  CT
Correct Answer(s)
A. Doppler untrasonography
C. Angiography

Explanation
Doppler ultrasonography and angiography are both diagnostic tools used to confirm the presence of thrombi. Doppler ultrasonography is a non-invasive imaging technique that uses sound waves to create images of blood flow in the veins and arteries, allowing for the detection of blood clots. Angiography, on the other hand, involves the injection of a contrast dye into the blood vessels, followed by X-ray imaging, which can help visualize any blockages or clots in the blood vessels. Therefore, both Doppler ultrasonography and angiography are effective in confirming the presence of thrombi.

  Beta blockers
- C.
  
  Warfain
- D.
  
  Thrombolytics
Correct Answer(s)
A. Heparin
C. Warfain
D. Thrombolytics

Explanation
Heparin, warfarin, and thrombolytics are all used as treatments for thrombi. Heparin is an anticoagulant that prevents the formation of blood clots. Warfarin is also an anticoagulant that works by inhibiting the production of certain clotting factors. Thrombolytics, on the other hand, are medications that help dissolve existing blood clots. Therefore, all three of these treatments are effective in managing thrombi. Beta blockers, however, are not used for this purpose and do not have an impact on blood clotting.

A diabetic patient comes to the doctor complaining about sever pain in his legs brought on by ambulation. The nurse suspects which of the following conditions?
- A.
  
  Atherosclerosis
- B.
  
  Peripheral Artery Disease
- C.
  
  Arteriosclerosis
Correct Answer
B. Peripheral Artery Disease

Explanation
The nurse suspects that the diabetic patient is experiencing Peripheral Artery Disease (PAD) due to the severe pain in his legs brought on by ambulation. PAD is a condition where the arteries that supply blood to the legs become narrowed or blocked, leading to reduced blood flow. This can cause pain, cramping, and weakness in the legs, especially during physical activity. Diabetic patients are at a higher risk for developing PAD due to the damage that high blood sugar levels can cause to blood vessels. Atherosclerosis and arteriosclerosis are both conditions that can contribute to the development of PAD.

Which of the following is a condition in which the blood supply to the heart musecles is completely or partially blocked due to atherosclerosis that develpos in the arteries that encircle the heart, narrowing the arteries, and blocking blood flow?
- A.
  
  Peripheral Artery Disease
- B.
  
  Myocardial Ischemia
- C.
  
  Coronary Artery Disease
Correct Answer
C. Coronary Artery Disease

Explanation
Coronary Artery Disease is the correct answer because it accurately describes a condition where the blood supply to the heart muscles is partially or completely blocked due to atherosclerosis in the arteries surrounding the heart. This leads to the narrowing of the arteries and a subsequent blockage of blood flow. Peripheral Artery Disease refers to a condition where there is a blockage in the arteries outside of the heart, while Myocardial Ischemia refers to a lack of blood flow and oxygen to the heart muscles, which can be a result of coronary artery disease.

- A.
  
  Coronary Artery Disease
- B.
  
  Myocardial Ischemia
- C.
  
  Myocardial Infarction
Correct Answer
B. Myocardial Ischemia

Explanation
Myocardial ischemia refers to the imbalance between coronary blood supply and myocardial demand. This condition occurs when the blood flow to the heart muscle is reduced, usually due to narrowed or blocked coronary arteries. As a result, the heart muscle does not receive enough oxygen and nutrients, leading to chest pain or discomfort known as angina. If the blood flow is severely restricted or completely blocked, it can result in a heart attack, known as myocardial infarction. Coronary artery disease is a broader term that encompasses the narrowing or blockage of the coronary arteries, which can lead to myocardial ischemia and myocardial infarction.

Which of the following is the most common reason for myocardial ischemia?
- A.
  
  Coronary Spasms
- B.
  
  Hypotension
- C.
  
  Atherosclerotic plaques
Correct Answer
C. Atherosclerotic plaques

Explanation
Atherosclerotic plaques are the most common reason for myocardial ischemia. These plaques are formed by the buildup of fatty deposits, cholesterol, and other substances in the walls of the coronary arteries. Over time, these plaques can narrow the arteries and restrict blood flow to the heart muscle. This reduced blood flow can lead to myocardial ischemia, which is a condition where the heart muscle does not receive enough oxygen and nutrients. This can cause chest pain, known as angina, and in severe cases, can lead to a heart attack.

- D.
  
  Anemia
- E.
  
  Arrhythmias
Correct Answer(s)
A. Coronary spasm
C. Hypotension
D. Anemia
E. Arrhythmias

Explanation
Myocardial infarction, commonly known as a heart attack, can be caused by various conditions. Coronary spasm is a condition where the coronary arteries, which supply blood to the heart, suddenly constrict, leading to reduced blood flow and potentially causing a heart attack. Hypotension, or low blood pressure, can also lead to inadequate blood supply to the heart and result in a heart attack. Anemia, a condition characterized by a decrease in red blood cells or hemoglobin, can cause a lack of oxygen delivery to the heart, increasing the risk of myocardial infarction. Arrhythmias, abnormal heart rhythms, can disrupt the heart's blood supply and trigger a heart attack.

- A.
  
  Stable Angina
- B.
  
  Silent Ischemia
- C.
  
  Prinzmental Angina
Correct Answer
B. Silent Ischemia

Explanation
The findings of left ventricular gallop and S3 are consistent with Silent Ischemia. Silent ischemia refers to a condition where there is inadequate blood flow to the heart muscle, leading to symptoms such as fatigue, dyspnea, and unease, but without the typical chest pain associated with angina. The presence of left ventricular gallop and S3 on assessment suggests impaired heart function, which can occur in silent ischemia due to reduced blood supply to the heart.

General transient ST segment depression and T wave inversion are characteristic signs of which of the following?
- A.
  
  Atheroscerotic plaque
- B.
  
  Angina
- C.
  
  Ischemia
Correct Answer
C. Ischemia

Explanation
General transient ST segment depression and T wave inversion are characteristic signs of ischemia. Ischemia refers to a lack of blood flow to a specific area of the body, often due to a narrowing or blockage of blood vessels. In the context of the heart, ischemia can result from atherosclerotic plaque buildup, which can lead to angina (chest pain) and potentially a heart attack. The ST segment depression and T wave inversion seen in ischemia are indicative of abnormal electrical activity in the heart, suggesting a lack of oxygen and nutrients reaching the cardiac muscle.

  Nitrates
- C.
  
  Antilipemics
Correct Answer
B. Nitrates

Explanation
Nitrates are medications that dilate both arteries and veins, leading to a reduction in myocardial oxygen demands. By dilating the blood vessels, nitrates increase blood flow and oxygen supply to the heart, while also reducing the workload on the heart. This can help relieve symptoms of angina, a condition characterized by chest pain or discomfort caused by a reduced blood flow to the heart. Therefore, nitrates are commonly used to treat angina and reduce myocardial oxygen demands.

Which of the following terms results from prolonged ischemia that causes irreversible damage to the heart muscle?
- A.
  
  Myocardial Infarction
- B.
  
  Unstable Angina
- C.
  
  Coronary Artery Disease
Correct Answer
A. Myocardial Infarction

Explanation
Prolonged ischemia refers to a reduced blood supply to the heart muscle, which can lead to irreversible damage. This condition is known as myocardial infarction, commonly referred to as a heart attack. During a heart attack, the blood flow to a specific area of the heart is blocked, causing the heart muscle tissue to die due to lack of oxygen and nutrients. Unstable angina, on the other hand, refers to chest pain caused by reduced blood flow to the heart, but it does not result in irreversible damage. Coronary artery disease is a broader term that encompasses various conditions that narrow or block the blood vessels supplying the heart, leading to decreased blood flow and potential heart muscle damage.

Which of the following terms describes the tissue in the entire thickness of a portion of the cardiac wall dying?
- A.
  
  Subendocardial infarction
- B.
  
  Transmural infarction
- C.
  
  Myocardial Infarction
Correct Answer
B. Transmural infarction

Explanation
Transmural infarction is the correct answer because it refers to the death of tissue in the entire thickness of a portion of the cardiac wall. This means that the tissue damage extends from the innermost layer (endocardium) to the outermost layer (epicardium) of the heart. Subendocardial infarction, on the other hand, refers to tissue death limited to the innermost layer of the cardiac wall, while myocardial infarction is a broader term that encompasses both subendocardial and transmural infarctions.

Which of the following presents as new-onset angina, at rest, or occuring in increasing severity or frequency, important to recognize because it means that atherosclerotic plaque has become complicated and infarction is likely to occur.
- A.
  
  Stable angina
- B.
  
  Prinzmental Angina
- C.
  
  Unstable Angina
Correct Answer
C. Unstable Angina

Explanation
Unstable angina presents as new-onset angina that occurs at rest or increases in severity or frequency. It is important to recognize because it indicates that atherosclerotic plaque has become complicated and there is a high risk of myocardial infarction (heart attack) occurring. Unlike stable angina, which is predictable and occurs with exertion or stress, unstable angina is unpredictable and can occur even at rest. Prompt medical attention is necessary for unstable angina to prevent further complications.

Which of the following of MONA, for treatment of myocardial infarction is given to inhibit platelet aggregation
- A.
  
  Aspirin
- B.
  
  Nitroglycerin
- C.
  
  Oxygen
Correct Answer
A. Aspirin

Explanation
Aspirin is given to inhibit platelet aggregation in the treatment of myocardial infarction. It works by inhibiting the production of prostaglandins, which are responsible for promoting platelet aggregation. By preventing platelets from clumping together, aspirin helps to prevent the formation of blood clots that can further block blood flow to the heart. This reduces the risk of complications and further damage to the heart muscle during a myocardial infarction. Nitroglycerin is used to relieve chest pain and improve blood flow to the heart, while oxygen is given to increase oxygen supply to the heart muscle.

  Pericardial Effusion
Correct Answer
A. Pericarditis

Explanation
Pericarditis refers to inflammation of the sac surrounding the heart, causing it to become roughened and scarred. This condition can be caused by various factors such as infections, autoimmune disorders, or heart attacks. Symptoms of pericarditis may include chest pain, fever, and a friction rub sound heard during a physical examination. Treatment typically involves addressing the underlying cause and managing symptoms with medication, rest, and sometimes, drainage of excess fluid from the pericardial sac.

Which of the following enzymes are most important in identifying Myocardial infarction
- A.
  
  Troponin I
- B.
  
  Tropinase I
- C.
  
  Troponin T
- D.
  
  Troponin 3
Correct Answer(s)
A. Troponin I
C. Troponin T

Explanation
Troponin I and Troponin T are the most important enzymes in identifying myocardial infarction. Troponin I is a protein found in cardiac muscle cells and is released into the bloodstream when there is damage to the heart muscle. Troponin T is another protein found in cardiac muscle cells and is also released into the bloodstream during a heart attack. These enzymes are specific to the heart and their elevated levels in the blood indicate myocardial infarction. Tropinase I and Troponin 3 are not enzymes related to myocardial infarction.

A patient complains of sudden onset severe retrosternal chest pain that worsens with respiratory effort, primarily inspiration. The patient says that the pain decreases when he leans forward and also says he has difficulty swallowing. Which of the following conditions is consistent with the findings?
- A.
  
  Cardiomyapathy
- B.
  
  Pericarditis
- C.
  
  Myocardial Infarction
Correct Answer
B. Pericarditis

Explanation
The patient's symptoms of sudden onset severe retrosternal chest pain that worsens with respiratory effort, primarily inspiration, along with relief of pain when leaning forward and difficulty swallowing, are consistent with pericarditis. Pericarditis is inflammation of the pericardium, the sac surrounding the heart. The pain is typically sharp and pleuritic, meaning it worsens with deep breathing or coughing. Leaning forward can relieve the pain by reducing pressure on the inflamed pericardium. Difficulty swallowing may occur due to compression of the esophagus by an enlarged pericardium. Cardiomyopathy and myocardial infarction would present with different symptoms and findings.

- A.
  
  Pericarditis
- B.
  
  Pericardial Effusion
- C.
  
  Pericardial Rub
Correct Answer
B. Pericardial Effusion

Explanation
Pericardial effusion refers to the accumulation of fluid in the pericardial cavity, which is the space between the layers of the pericardium, the sac that surrounds the heart. This condition can occur due to various reasons, such as inflammation, infection, trauma, or cancer. It can lead to symptoms like chest pain, shortness of breath, and a feeling of heaviness in the chest. Treatment for pericardial effusion depends on the underlying cause and may involve medication, drainage of the fluid, or surgery. Pericarditis refers to inflammation of the pericardium, while pericardial rub is a specific sound heard during a physical examination of the heart.

- A.
  
  Pleural effusion
- B.
  
  Pericardial Effusion
- C.
  
  Tamponede
Correct Answer
C. Tamponede

Explanation
The correct answer is "Tamponade." Tamponade refers to the rapid accumulation of fluid in the pericardial cavity, which leads to compression of the heart. This can result in impaired cardiac function and potentially life-threatening consequences. Pleural effusion refers to the accumulation of fluid in the pleural cavity, while pericardial effusion specifically refers to the accumulation of fluid in the pericardial cavity.

Pericardial Effusion, may cause which of the following conditions?
- A.
  
  Left-sided heart failure
- B.
  
  Right-sided heart failure
- C.
  
  Coronary Artery dieaese
Correct Answer
B. Right-sided heart failure

Explanation
Pericardial effusion refers to the accumulation of fluid in the pericardial sac, which surrounds the heart. This excess fluid can put pressure on the heart, leading to impaired filling and function of the right side of the heart. As a result, right-sided heart failure can occur, characterized by symptoms such as fluid retention, swelling in the legs and abdomen, and impaired blood flow to the lungs. Therefore, pericardial effusion may cause right-sided heart failure.

Which of the following condition s is a Cardiomypathy where the ventricles are stiff and cannot fill properly?
- A.
  
  Restrictive
- B.
  
  Hypertrophic
- C.
  
  Dilated (congestive)
Correct Answer
A. Restrictive

Explanation
Restrictive cardiomyopathy is a condition where the ventricles of the heart become stiff and lose their ability to relax and fill properly. This results in decreased blood flow to the rest of the body. Hypertrophic cardiomyopathy, on the other hand, is characterized by thickening of the heart muscle, while dilated cardiomyopathy refers to a condition where the heart chambers become enlarged and weakened. Therefore, the correct answer is restrictive cardiomyopathy.

Which of the following cardiomypathies are where the walls of of the ventricles thicken and become stiff?
- A.
  
  Restrictive
- B.
  
  Hypertrophic
- C.
  
  Dilated (congestive)
Correct Answer
B. Hypertrophic

Explanation
Hypertrophic cardiomyopathy is a type of cardiomyopathy where the walls of the ventricles (usually the left ventricle) thicken and become stiff. This thickening can interfere with the heart's ability to pump blood effectively, leading to symptoms such as chest pain, shortness of breath, and fainting. It is a genetic condition and can be inherited from a parent. Treatment options for hypertrophic cardiomyopathy include medications to manage symptoms, surgical procedures, and lifestyle changes.

- C.
  
  Dilated (congestive)
Correct Answer
C. Dilated (congestive)

Explanation
Dilated (congestive) cardiomyopathy is a condition where the ventricles of the heart become enlarged and weakened, leading to a decreased ability to pump enough blood to meet the body's needs. This can result in symptoms such as fatigue, shortness of breath, and fluid retention. Restrictive cardiomyopathy is characterized by the stiffening of the ventricles, while hypertrophic cardiomyopathy involves the thickening of the heart muscle.

Mutliple myeloma and amyloidosis are example of which cardiomypathy?
- A.
  
  Restrictive
- B.
  
  Hypertrophic
- C.
  
  Dialted (congestive)
Correct Answer
A. Restrictive

Explanation
Multiple myeloma and amyloidosis are examples of diseases that can lead to restrictive cardiomyopathy. In restrictive cardiomyopathy, the heart muscle becomes stiff and less compliant, which impairs its ability to relax and fill with blood properly. This can result in symptoms such as fatigue, shortness of breath, and fluid retention. Both multiple myeloma and amyloidosis can cause the deposition of abnormal proteins in the heart muscle, leading to the development of restrictive cardiomyopathy.

Which of the following cardiomypathies is uncontrollien HTN causing ventricles and septum to come hypertrophic, shrinking the heart chambers and decreasing blood volume that leaves the heart, Decreasing Cardiac Outoput and responsible for deaths in competitive athletes?
- A.
  
  Restricted
- B.
  
  Hypertrophic
- C.
  
  Congested
Correct Answer
B. Hypertrophic

Explanation
Hypertrophic cardiomyopathy is the correct answer. This condition is characterized by the thickening of the ventricles and septum of the heart, leading to a decrease in the volume of blood that can be pumped out of the heart. This decrease in cardiac output can result in symptoms such as shortness of breath, chest pain, and fainting. In some cases, hypertrophic cardiomyopathy can be caused by uncontrolled hypertension, and it has been known to be a cause of sudden cardiac death in competitive athletes.

- A.
  
  Valvular Dysfunction
- B.
  
  Valvular Stenosis
- C.
  
  Valvular Insufficiency
Correct Answer
A. Valvular Dysfunction

Explanation
Disorders of the endocardium can lead to damage in the heart valves, which are composed of endocardial tissue. This damage can result in various abnormalities in the functioning of the valves, including stenosis (narrowing) or insufficiency (leakage). Therefore, the term "Valvular Dysfunction" encompasses both valvular stenosis and valvular insufficiency, making it the correct answer.

Which of the following conditions occurs when blood cannot flow forward due to the orifice being constricted and narrowed, causing the pressure in the chamber to rise and the myocardium to work harder and eventually hypertrophy?
- A.
  
  Valvular Dysfunction
- B.
  
  Valvular Stenosis
- C.
  
  Valvular Regurgitation
Correct Answer
B. Valvular Stenosis

Explanation
Valvular stenosis occurs when the orifice of a heart valve is constricted and narrowed, preventing blood from flowing forward. This constriction causes an increase in pressure within the chamber, forcing the myocardium to work harder to pump blood through the narrowed valve. Over time, this increased workload can lead to hypertrophy of the myocardium. Valvular dysfunction and valvular regurgitation refer to other types of valve abnormalities, but they do not specifically involve the narrowing of the valve orifice as seen in valvular stenosis.
