Interactive Cardiology MCQs 36: Clinical Examination II - All About Cardiovascular System and Disorders

Q1

During the physical examination of a patient with Hypertrophic Obstructive Cardiomyopathy (HOCM), a premature ventricular contraction (PVC) occurs. Which of the following describes the classic Brockenbrough-Braunwald-Morrow sign observed in the post-extrasystolic beat?

Q2

A patient with long-standing mitral stenosis develops severe hoarseness over several weeks. A chest radiograph reveals a massively enlarged left atrium. What is the clinical eponym for this syndrome, and what is its anatomical basis?

Q3

A ‘wide physiological split’ of the second heart sound (S2) means the split is abnormally wide during expiration and widens even further during inspiration. Which of the following conditions classically causes this by producing a prematurely early A2?

Q4

A patient with uremia presents with pleuritic chest pain. Auscultation reveals a classic triphasic pericardial friction rub. What specific cardiac cycle events correspond to the three distinct components of this classic rub?

Q5

During bedside dynamic auscultation, inhalation of Amyl Nitrite is utilized. How does this pharmacological maneuver primarily alter hemodynamics, and what is its effect on the murmur of left-sided regurgitant lesions (e.g., Mitral Regurgitation, Aortic Regurgitation)?

Q6

A 45-year-old male develops acute, severe Aortic Regurgitation (AR) secondary to endocarditis. Which of the following physical examination profiles distinctly differentiates ACUTE severe AR from CHRONIC severe AR?

Q7

Palpation of the carotid pulse reveals a “spike and dome” contour (Pulsus Bisferiens) characterized by two distinct palpable systolic peaks. Which of the following combinations of lesions is this finding most classically associated with?

Q8

The Levine Grading System is universally used to grade the intensity of heart murmurs on a scale of 1 to 6. What specific clinical finding distinguishes a Grade 4 murmur from a Grade 3 murmur?

Q9

A continuous, low-pitched murmur is auscultated at the base of the neck in a young adult. It is loudest during diastole and completely disappears when light pressure is applied to the jugular vein or when the patient turns their head. What is the diagnosis?

Q10

A patient presenting with an acute inferior ST-elevation myocardial infarction develops sudden, severe hypotension. Physical examination reveals an elevated Jugular Venous Pulse (JVP) with a prominent ‘y’ descent and Kussmaul’s sign, but auscultation of the lungs is completely clear. What is the most likely diagnosis?

Q11

In a patient with known Rheumatic Mitral Stenosis, the severity of the obstruction can often be estimated clinically. Which of the following physical findings suggests that the mitral valve has become severely calcified and functionally immobile?

Q12

When evaluating a patient with Aortic Stenosis, the absolute loudness (Grade) of the systolic murmur correlates poorly with the hemodynamic severity of the obstruction. Which clinical auscultatory feature provides a much more reliable indicator of severe stenosis?

Q13

In severe chronic Mitral Regurgitation (MR), the left ventricle and left atrium undergo significant volume overload. Which combination of auscultatory findings confirms hemodynamically severe MR with a massive regurgitant volume?

Q14

During examination of the Jugular Venous Pulse (JVP), Kussmaul’s sign is identified. What is the fundamental pathophysiological mechanism underlying this sign?

Q15

A 25-year-old female is evaluated for palpitations. Auscultation reveals a mid-systolic click and a late systolic murmur. When the patient is asked to suddenly transition from a standing position to a rapid squat, how do the auscultatory findings change?

Q16

Fundoscopic examination of a patient with bounding pulses reveals visible pulsations of the retinal arterioles. What is the name of this specific eponymous sign of severe Aortic Regurgitation?

Q17

A neonate is found to have a harsh, extremely loud (Grade 5/6) holosystolic murmur with a prominent parasternal thrill. Echocardiography reveals a small, restrictive Ventricular Septal Defect (VSD) with entirely normal right heart pressures. What is the historical name for this specific clinical presentation?

Q18

A patient presents with tachycardia (120 bpm) and signs of decompensated heart failure. Auscultation reveals a single, loud mid-diastolic extra heart sound producing a ‘gallop’ cadence. What causes this specific ‘summation gallop’?

Q19

Palpation of the apical impulse (PMI) provides critical clues to ventricular pathology. How does a ‘heaving’ (sustained) apex beat hemodynamically differ from a ‘thrusting’ (hyperdynamic) apex beat?

Q20

In a normal Jugular Venous Pulse (JVP) waveform, the ‘v’ wave occurs in late systole. What physiological event does the normal ‘v’ wave represent?

Q21

During bedside evaluation of the Jugular Venous Pulse, the examining physician completely fails to observe any ‘a’ waves, noting only ‘c-v’ waves and a ‘y’ descent. Which arrhythmia is invariably present?

Q22

Pulsus Paradoxus is classically defined as a drop in systolic blood pressure greater than 10 mmHg during inspiration. What is the fundamental hemodynamic mechanism driving this in Cardiac Tamponade?

Q23

Echocardiographic Doppler of mitral inflow velocities provides a critical non-invasive way to differentiate Constrictive Pericarditis from Restrictive Cardiomyopathy. What specific respiratory variation pattern strongly favors Constrictive Pericarditis?

Q24

The Graham Steell murmur is auscultated in a patient with severe, long-standing pulmonary hypertension. What are the acoustic characteristics and anatomical origin of this murmur?

Q25

Carotid Sinus Massage is applied during a narrow-complex tachycardia at 150 bpm. The ventricular rate abruptly slows, unmasking underlying regular ‘sawtooth’ baseline waves, but the tachycardia does not terminate and resumes its 150 bpm rate when massage is stopped. What is the diagnosis?
