Multiple choice

How many chest compressions should you give per minute during CPR?

  1. 60-80

  2. 100-120

  3. 120-150

  4. 150-180
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The recommended rate for chest compressions during CPR is 100-120 compressions per minute.

Multiple choice

Which type of heart disease is characterized by the buildup of plaque in the arteries, leading to reduced blood flow to the heart?

  1. Coronary artery disease

  2. Heart failure

  3. Arrhythmia

  4. Cardiomyopathy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coronary artery disease (CAD) is a condition in which plaque builds up inside the coronary arteries, which supply blood to the heart. This buildup can narrow the arteries and reduce blood flow to the heart, leading to chest pain, shortness of breath, and other symptoms.

Multiple choice

Which medical condition is characterized by the buildup of scar tissue in the heart muscle?

  1. Cardiomyopathy

  2. Heart failure

  3. Arrhythmia

  4. Myocarditis
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cardiomyopathy is a condition in which the heart muscle becomes enlarged, thickened, or stiff. This can lead to heart failure, arrhythmias, and other heart problems.

Multiple choice

Which medical condition is characterized by an irregular heartbeat?

  1. Arrhythmia

  2. Cardiomyopathy

  3. Heart failure

  4. Myocarditis
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Arrhythmia is a condition in which the heart beats too fast, too slow, or irregularly. This can lead to chest pain, shortness of breath, fainting, and other symptoms.

Multiple choice

What is angina?

  1. A type of chest pain caused by reduced blood flow to the heart

  2. A type of heart attack

  3. A type of arrhythmia

  4. A type of heart failure
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Angina is a type of chest pain that occurs when the blood flow to the heart is reduced. This can be caused by a number of factors, including atherosclerosis, heart valve disease, and coronary artery spasm.

Multiple choice

What is the most common type of angina?

  1. Stable angina

  2. Unstable angina

  3. Variant angina

  4. Microvascular angina
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Stable angina is the most common type of angina. It is characterized by chest pain or discomfort that occurs with exertion and goes away with rest.

Multiple choice

What is unstable angina?

  1. A type of angina that is more severe than stable angina

  2. A type of angina that is less severe than stable angina

  3. A type of angina that is caused by a heart attack

  4. A type of angina that is caused by coronary artery spasm
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Unstable angina is a type of angina that is more severe than stable angina. It is characterized by chest pain or discomfort that occurs at rest or with minimal exertion and does not go away with rest.

Multiple choice

What is variant angina?

  1. A type of angina that is caused by coronary artery spasm

  2. A type of angina that is caused by a heart attack

  3. A type of angina that is caused by atherosclerosis

  4. A type of angina that is caused by heart valve disease
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Variant angina is a type of angina that is caused by coronary artery spasm. This is a sudden tightening of the coronary arteries that can reduce blood flow to the heart.

Multiple choice

How is angina diagnosed?

  1. Physical exam

  2. Medical history

  3. Electrocardiogram (ECG)

  4. Stress test

  5. Echocardiogram

  6. Coronary angiography

  7. All of the above
Reveal answer Fill a bubble to check yourself
G Correct answer
Explanation

Angina is diagnosed based on a physical exam, medical history, electrocardiogram (ECG), stress test, echocardiogram, and coronary angiography.

Multiple choice

What is the primary cardiovascular response to the stress of shooting a competition?

  1. Increased heart rate

  2. Decreased blood pressure

  3. Increased stroke volume

  4. Decreased cardiac output
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The stress of shooting a competition typically leads to an increase in heart rate, as the body prepares for the physical and mental demands of the task.
