Free AMSN Cardiovascular Disorders Questions and Answers — Questions and Answers
Question 1: Which of the following is a common symptom of acute myocardial infarction (heart attack)?
- Sudden onset of chest pain radiating to the left arm (Correct answer)
- Sharp pain in the lower abdomen
- Gradual onset of leg pain
- Intermittent headaches
Correct answer: Sudden onset of chest pain radiating to the left arm
Acute myocardial infarction (AMI), commonly known as a heart attack, is characterized by the sudden blockage of blood flow to the heart muscle. The classic and most common symptom is severe chest pain, often described as pressure or tightness, which frequently radiates to the left arm. This distinct presentation is a critical indicator for prompt diagnosis and treatment.
Question 2: What is the primary goal of administering thrombolytic therapy in patients with acute coronary syndrome?
- To reduce hypertension
- To lower cholesterol levels
- To prevent arrhythmias
- To dissolve the blood clot obstructing the coronary artery (Correct answer)
Correct answer: To dissolve the blood clot obstructing the coronary artery
Thrombolytic therapy, often referred to as 'clot-busting' drugs, is administered in acute coronary syndrome to dissolve the blood clot obstructing a coronary artery. By breaking down the clot, this therapy aims to restore blood flow to the heart muscle. This crucial intervention helps limit the extent of myocardial damage and improve patient outcomes, especially when administered promptly.
Question 3: Which diagnostic test is most commonly used to confirm the presence of a myocardial infarction?
- Echocardiogram
- Electrocardiogram (ECG) (Correct answer)
- Chest X-ray
- Complete blood count (CBC)
Correct answer: Electrocardiogram (ECG)
An electrocardiogram (ECG or EKG) is the most commonly used and initial diagnostic test to confirm the presence of a myocardial infarction. It records the electrical activity of the heart and can reveal characteristic changes, such as ST-segment elevation or T-wave inversions, indicative of heart muscle damage or ischemia. The ECG provides immediate, vital information for guiding treatment decisions.
Question 4: What is the recommended lifestyle modification for a patient with hypertension to reduce cardiovascular risk?
- Increasing salt intake
- Engaging in regular physical activity (Correct answer)
- Consuming a high-fat diet
- Reducing water intake
Correct answer: Engaging in regular physical activity
Engaging in regular physical activity is a cornerstone of lifestyle modification for managing hypertension and reducing overall cardiovascular risk. Exercise helps lower blood pressure, improve cholesterol levels, manage weight, and enhance cardiovascular health. This intervention is highly effective in preventing and controlling cardiovascular diseases.
Question 5: Which medication is commonly prescribed to manage chronic heart failure by reducing fluid overload?
- Beta-blockers
- ACE inhibitors
- Diuretics (Correct answer)
- Statins
Correct answer: Diuretics
Diuretics are commonly prescribed medications for patients with chronic heart failure because they help reduce fluid overload. These drugs promote the elimination of excess fluid and sodium through increased urine output, thereby decreasing congestion and symptoms like swelling and shortness of breath. This action helps to reduce the workload on the failing heart.
