ECG Quiz: Trivia Questions! Test

1.

The purpose of an ECG is to look for abnormalities of the heart?
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
An ECG, or electrocardiogram, is a diagnostic test that measures the electrical activity of the heart. By examining the electrical patterns and rhythms recorded by the ECG, healthcare professionals can detect any abnormalities in the heart's functioning. This makes it a valuable tool in diagnosing various heart conditions, such as arrhythmias, heart attacks, and heart defects. Therefore, the statement that the purpose of an ECG is to look for abnormalities of the heart is true.

An ECG does not use the heart's electrical impulses/signals to determine whether a heart pattern is normal or abnormal?
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
An ECG (electrocardiogram) does use the heart's electrical impulses/signals to determine whether a heart pattern is normal or abnormal. It measures the electrical activity of the heart and displays it as a graph, allowing healthcare professionals to analyze the heart's rhythm and identify any abnormalities. Therefore, the statement that an ECG does not use the heart's electrical impulses/signals to determine whether a heart pattern is normal or abnormal is false.

Two of the heart's major functions include transportation of oxygen and nutrients throughout the body.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The heart plays a crucial role in transporting oxygen and nutrients throughout the body. It does this by pumping oxygen-rich blood from the lungs to the rest of the body's tissues and organs. The oxygen and nutrients are carried by the blood to provide energy and nourishment to the cells. Therefore, it is correct to say that one of the heart's major functions is the transportation of oxygen and nutrients throughout the body.

The ventricles are the shipping stations of the heart.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The heart's ventricles function as dispatch centers. The right ventricle sends deoxygenated blood to the lungs via the pulmonary artery, while the left ventricle propels oxygenated blood throughout the body using the aorta, the body's largest artery.

5.

The right atrium receives oxygen-rich blood.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The right atrium actually receives oxygen-poor blood from the body. It receives blood from the superior and inferior vena cava, which carry deoxygenated blood back to the heart. The oxygen-rich blood is received by the left atrium from the lungs. Therefore, the statement that the right atrium receives oxygen-rich blood is incorrect.

Which of the following is a symptom of a potential heart problem?
- A.
  
  Shortness of breath
- B.
  
  All of the above
- C.
  
  Fatigue
- D.
  
  Chest pain
- E.
  
  Heart palpitations
Correct Answer
B. All of the above

Explanation
All of the listed symptoms - fatigue, chest pain, heart palpitations, and shortness of breath - are potential symptoms of a heart problem. Therefore, "all of the above" is a correct answer.

Which of the following is NOT one of the waves of the heart used by an ECG machine?
- A.
  
  P
- B.
  
  V
- C.
  
  Q
- D.
  
  T
Correct Answer
B. V

Explanation
The waves of the heart used by an ECG machine are P, Q, and T. The V wave is not one of the waves used by an ECG machine.

The Leads of an ECG is divided into:
- A.
  
  6 limb Leads and 6 leg Leads
- B.
  
  6 chest leads and 6 back Leads
- C.
  
  6 limb Leads and 6 chest Leads
Correct Answer
C. 6 limb Leads and 6 chest Leads

Explanation
An ECG (electrocardiogram) measures the electrical activity of the heart. The leads are the electrodes placed on the body to record this activity. The correct answer is "6 limb Leads and 6 chest Leads". Limb leads are placed on the arms and legs to record the electrical signals in the frontal plane, while chest leads are placed on the chest to record signals in the horizontal plane. This combination of leads allows for a comprehensive assessment of the heart's electrical activity from different angles.

What is a risk factor for heart disease?
- A.
  
  Obesity
- B.
  
  Hypertension
- C.
  
  Smoking
- D.
  
  Diabetes
- E.
  
  All of the above
Correct Answer
E. All of the above

Explanation
All of the options listed (obesity, hypertension, smoking, and diabetes) are known risk factors for heart disease. Obesity puts extra strain on the heart and can lead to high blood pressure and diabetes, both of which increase the risk of heart disease. Hypertension, or high blood pressure, forces the heart to work harder and can damage blood vessels. Smoking damages blood vessels and increases the risk of plaque buildup in the arteries. Diabetes affects the body's ability to regulate blood sugar levels, which can damage blood vessels and increase the risk of heart disease. Therefore, all of these factors contribute to the risk of developing heart disease.

What are the main components to administer an ECG?
- A.
  
  ECG machine, lead wires and electrodes
- B.
  
  ECG machine, sterile wipes, electrodes and lead wires
- C.
  
  ECG machine, monitor strips, electrodes, lead wires, gel
- D.
  
  ECG machine, monitor strips, electrodes, lead wires, sterile wipes
Correct Answer
D. ECG machine, monitor strips, electrodes, lead wires, sterile wipes

Explanation
The main components to administer an ECG include an ECG machine, monitor strips, electrodes, lead wires, and sterile wipes. The ECG machine is necessary to record the electrical activity of the heart, while the monitor strips are used to display the ECG waveform. The electrodes are attached to the patient's skin to detect the electrical signals, and the lead wires connect the electrodes to the ECG machine. Sterile wipes are used to clean the patient's skin before attaching the electrodes, ensuring proper hygiene during the procedure.

In a normal ECG, the heart should beat:
- A.
  
  50-100 times per minute
- B.
  
  60-100 times per minute
- C.
  
  80-100 times per minute
Correct Answer
B. 60-100 times per minute

Explanation
The correct answer is 60-100 times per minute. This range is considered normal for a healthy adult heart rate. A heart rate below 60 beats per minute is called bradycardia, which may indicate a problem with the electrical system of the heart. On the other hand, a heart rate above 100 beats per minute is called tachycardia and can also be a sign of an underlying health issue. Therefore, a heart rate between 60-100 beats per minute is considered within the normal range for an ECG.
