Free Cardiographic Technician MCQ Questions And Answers — Questions and Answers
Question 1: A procedure that doesn't require entering the body cavity or puncturing or cutting the skin is:
- non-invasive (Correct answer)
- arthroscopy
- invasive
- physical therapy
Correct answer: non-invasive
Non-invasive procedures are diagnostic approaches that don't require skin punctures, incisions, or the insertion of foreign objects or materials into the body.
Question 2: A patient who is undergoing an exercise stress test is instructed to:
- Oxygen level
- physical appearance
- Heart rate
- all of the above (Correct answer)
Correct answer: all of the above
The patient should keep an eye on his or her heart rate, oxygen level, and physical appearance throughout the exercise stress test.
Question 3: The formula to determine cardiac output, often known as CO, Q, or Qc, is as follows:
- SV / HR = CO
- SV x HR = CO (Correct answer)
- SV - HR =CO
- SV + HR = CO
Correct answer: SV x HR = CO
Heart rate (HR) and stroke volume (SV), the amount of blood the heart expels with each beat, are combined to form carbon dioxide (CO).
Question 4: The term for the narrowing of the arteries supplying blood to the heart muscle is:
- atherosclerosis
- arterioscerosis
- coronary artery disease (Correct answer)
- peripheral vascular disease
Correct answer: coronary artery disease
cardiovascular disease. Plaque accumulation in the coronary arteries—the arteries that carry blood to the heart—causes coronary artery disease. Deposits of cholesterol make form plaque. Over time, plaque formation causes the interior of the arteries to narrow.
Question 5: What kind of substance is administered intravenously during a stress test in order to image blood flow?
- a nuclear isotope (Correct answer)
- a genetic marker
- flourescent serum
- C-12 atoms
Correct answer: a nuclear isotope
Nuclear imaging and nuclear medicine diagnosis. The use of radioisotopes in diagnostic techniques in medicine is crucial. They can be used in conjunction with imaging tools that record the gamma rays emitted from within to image the dynamic processes occurring in various bodily areas.
Question 6: What happens when Persantine (dipyridamole) is tested under Persantine-thallium stress?
- It lowers blood pressure
- It removes blockages in the heart
- It opens heart valves
- It stimulates the heart to work harder, the way it would during exercise (Correct answer)
Correct answer: It stimulates the heart to work harder, the way it would during exercise
Patients unable to exercise conventionally, as on a treadmill, can analyze blood flow to their hearts thanks to the use of persantine.
Question 7: When the ventricles are full, the amount of stretch on the heart muscles is referred to as:
- aortic pressure
- preload (Correct answer)
- venous pressure
- afterload
Correct answer: preload
Preload, which is referred to most usually as the volume in a ventricle right before the beginning of systole, is defined as the stretch of myocardium or end-diastolic volume of the ventricles.
