Sample Question Section by Topic
Cardiac Anatomy and Physiology
Understanding cardiac anatomy and physiology is foundational for success in the RDCS exam. Here are some sample questions to test your knowledge.
Sample Question 1
Question: What is the primary function of the left atrium?
Answer Choices:
- a) Pumps oxygenated blood to the body
- b) Receives deoxygenated blood from the body
- c) Receives oxygenated blood from the lungs
- d) Pumps deoxygenated blood to the lungs
Correct Answer: c) Receives oxygenated blood from the lungs
Explanation: The left atrium’s primary function is to receive oxygenated blood from the pulmonary veins and then pass it to the left ventricle, which pumps it to the rest of the body.
Sample Question 2
Question: Which structure electrically connects the atria to the ventricles?
Answer Choices:
- a) Sinus node
- b) Atrioventricular (AV) node
- c) Purkinje fibers
- d) Bundle of His
Correct Answer: d) Bundle of His
Explanation: The Bundle of His is part of the electrical conduction system of the heart that transmits impulses from the AV node to the ventricles.
Cardiac Pathology
Identifying and understanding cardiac pathology is crucial for accurate diagnosis and treatment. Let’s review some example questions to test your proficiency in this area.
Sample Question 1
Question: Which of the following conditions is characterized by a thickened interventricular septum?
Answer Choices:
- a) Dilated Cardiomyopathy
- b) Hypertrophic Cardiomyopathy
- c) Restrictive Cardiomyopathy
- d) Pericarditis
Correct Answer: b) Hypertrophic Cardiomyopathy
Explanation: Hypertrophic Cardiomyopathy is a condition where the interventricular septum thickens, potentially leading to obstructed blood flow out of the heart.
Sample Question 2
Question: What is a common echocardiographic finding in patients with mitral valve prolapse?
Answer Choices:
- a) Thickened aortic valve
- b) Posterior displacement of the mitral valve leaflets during systole
- c) Enlarged left ventricular cavity
- d) Reduced ejection fraction
Correct Answer: b) Posterior displacement of the mitral valve leaflets during systole
Explanation: Mitral valve prolapse is characterized by the abnormal bulging of one or both of the mitral valve leaflets into the left atrium during systole.
Diagnostic Techniques and Interpretation
Proficiency in diagnostic techniques and their interpretation is essential for accurate sonographic analysis. Test your understanding with the following questions.
Sample Question 1
Question: Which Doppler technique is most useful for assessing blood flow through a stenotic valve?
Answer Choices:
- a) Continuous Wave Doppler
- b) Pulsed Wave Doppler
- c) Color Flow Doppler
- d) M-mode
Correct Answer: a) Continuous Wave Doppler
Explanation: Continuous Wave Doppler is used for measuring high-velocity blood flow, making it suitable for assessing flow through stenotic valves, where velocities can exceed the capabilities of Pulsed Wave Doppler.
Sample Question 2
Question: When performing an echocardiogram, what does a “flattened” interventricular septum indicate in the parasternal short-axis view at the level of the ventricles?
Answer Choices:
- a) Normal finding during inspiration
- b) Left ventricular volume overload
- c) Right ventricular pressure overload
- d) Pericardial effusion
Correct Answer: c) Right ventricular pressure overload
Explanation: A “flattened” interventricular septum seen in the parasternal short-axis view indicates that the right ventricular pressure exceeds the left, often due to conditions like pulmonary hypertension or right ventricular outflow tract obstruction.
Clinical Scenarios and Case Studies
Clinical scenarios and case studies require you to apply your theoretical knowledge and diagnostic skills in practical situations. Here are some sample questions based on clinical case studies.
Sample Question 1
Clinical Scenario: A 64-year-old male presents with dyspnea and chest pain. Echo findings show an ejection fraction of 35% and hypokinesia of the anterior wall.
Question: What is the most likely diagnosis?
Answer Choices:
- a) Hypertrophic Cardiomyopathy
- b) Dilated Cardiomyopathy
- c) Myocardial Infarction
- d) Constrictive Pericarditis
Correct Answer: c) Myocardial Infarction
Explanation: The combination of low ejection fraction and localized wall motion abnormality (hypokinesia) in the anterior wall suggests myocardial infarction, often caused by blockage in the coronary artery supplying this area.
Sample Question 2
Clinical Scenario: During a routine echo, a 45-year-old woman is noted to have a large pericardial effusion with evidence of diastolic collapse of the right atrium.
Question: What is the most appropriate next step?
Answer Choices:
- a) Observation and follow-up in a week
- b) Start anti-inflammatory medications
- c) Immediate pericardiocentesis
- d) Referral for cardiac surgery
Correct Answer: c) Immediate pericardiocentesis
Explanation: The presence of diastolic collapse of the right atrium is an echocardiographic sign of cardiac tamponade, necessitating urgent intervention such as pericardiocentesis to relieve the pressure on the heart.
