- D.
In hypotensive patients BP should always be determined by Korotkoff sounds
- E.
Simultaneous Palpation of radial artery prevents underestimation of BP
Correct Answer
D. In hypotensive patients BP should always be determined by Korotkoff soundsExplanation
In hypotensive patients, determining blood pressure solely based on Korotkoff sounds may not be accurate. Hypotensive patients have low blood pressure, and in some cases, the Korotkoff sounds may not be audible or may be very faint. In such situations, alternative methods such as invasive blood pressure monitoring or Doppler ultrasound may be necessary to accurately measure blood pressure.Rate this question:

In Pre-excited AF , treatment of choice is
- A.
Beta blockers
- B.
Calcium blockers
- C.
Adenosine
- D.
Amiodarone
- E.
None of the above
Correct Answer
E. None of the aboveExplanation
In Pre-excited AF, the treatment of choice is not any of the options provided. Pre-excited AF refers to atrial fibrillation that occurs in individuals with a pre-existing accessory pathway, such as Wolff-Parkinson-White syndrome. In these cases, the use of medications like beta blockers, calcium blockers, adenosine, or amiodarone may actually worsen the condition or lead to more rapid ventricular response. The treatment approach for pre-excited AF typically involves electrical cardioversion or catheter ablation to eliminate the accessory pathway and restore normal heart rhythm.Rate this question:

- A.
Non STEMI
- B.
Significant hypertension at initial evaluation
- C.
Pregnancy
- D.
Major surgery within 3 weeks
- E.
Ischemic stroke > 3 months
Correct Answer
A. Non STEMIExplanation
The correct answer is "Non STEMI" because thrombolysis is not indicated in non-ST segment elevation myocardial infarction (non-STEMI) cases. Thrombolysis is primarily used in ST segment elevation myocardial infarction (STEMI) cases where there is evidence of complete occlusion of a coronary artery. Non-STEMI cases involve partial occlusion or blockage of the coronary artery, and other treatment options such as medications or invasive procedures may be more appropriate.Rate this question:

All of the following are true in HCM except
- A.
Amiodarone is useful in for primary prevention of SCD in high risk patient.
- B.
Beta blockers have been useful to relieve symptoms of HF
- C.
Verapamil has the capacity to improve exercise capacity
- D.
None of the above
Correct Answer
A. Amiodarone is useful in for primary prevention of SCD in high risk patient.Explanation
Amiodarone is not useful for primary prevention of sudden cardiac death (SCD) in high-risk patients. Amiodarone is primarily used for the treatment of arrhythmias, including ventricular arrhythmias, but it is not recommended as a first-line therapy for primary prevention of SCD. Other interventions such as implantable cardioverter-defibrillators (ICDs) are more effective in reducing the risk of SCD in high-risk patients. Therefore, the statement that Amiodarone is useful for primary prevention of SCD in high-risk patients is not true.Rate this question:

First choice of drug to be given in acute myocardial infarction
- A.
Clopidogrel
- B.
Aspirin (Disprin)
- C.
Statin
- D.
Nitrates(Sorbitrate)
Correct Answer
B. Aspirin (Disprin)Explanation
Aspirin (Disprin) is the first choice of drug to be given in acute myocardial infarction. This is because aspirin is an antiplatelet medication that helps to prevent blood clots from forming in the arteries, which is crucial in the management of a heart attack. By inhibiting platelet aggregation, aspirin reduces the risk of further clot formation and helps to restore blood flow to the heart muscle. It is a widely used and effective medication in the acute treatment of myocardial infarction.Rate this question:

Drugs/Class of drugs contraindicated in ischemic VT
- A.
Lignocaine
- B.
Amiodarone
- C.
Beta blocker
- D.
Calcium channel blockers
Correct Answer
D. Calcium channel blockersExplanation
Calcium channel blockers are contraindicated in ischemic ventricular tachycardia (VT) because they can further depress myocardial contractility and worsen ischemia. These drugs work by blocking the entry of calcium into the myocardial cells, which reduces the contractility of the heart muscle. In ischemic VT, there is already a reduced blood supply to the heart, and the heart muscle is not receiving enough oxygen. Calcium channel blockers can exacerbate this condition by further reducing the contractility of the heart, leading to potentially life-threatening consequences. Therefore, they should be avoided in the treatment of ischemic VT.Rate this question:

Antihypertensive agent contraindicated in accelerated HTN complicating in acute myocardial infarction
- A.
Metoprolol
- B.
Sublingual Nifedipine
- C.
Nitrates
- D.
Torsemide
Correct Answer
D. TorsemideExplanation
Torsemide is a loop diuretic that is commonly used to treat fluid retention and high blood pressure. However, in the context of accelerated hypertension complicating acute myocardial infarction (AMI), it is contraindicated. This is because Torsemide can cause excessive fluid loss and decrease blood volume, which can worsen the already compromised cardiac function in AMI. Therefore, it is important to avoid Torsemide in this specific scenario to prevent further complications.Rate this question:

First line of antihypertensive for primary hypertension in patients <50 years
- A.
ACEI/ARB
- B.
Beta blockers
- C.
Diuretics
- D.
Calcium channel blockers
Correct Answer
A. ACEI/ARBExplanation
ACEI/ARB (Angiotensin Converting Enzyme Inhibitors/Angiotensin Receptor Blockers) are the first-line antihypertensive medications recommended for patients under 50 years of age with primary hypertension. These drugs work by blocking the effects of angiotensin, a hormone that constricts blood vessels, thereby reducing blood pressure. They are effective in treating hypertension and have shown additional benefits in preventing cardiovascular diseases. Beta blockers, diuretics, and calcium channel blockers are also commonly used antihypertensive medications, but ACEI/ARB are generally preferred as the initial treatment option for this specific patient population.Rate this question:

Cardiac syncope is likely in all except
- A.
Elderly
- B.
Structural heart disease
- C.
Frequent recurrence and prolonged history
- D.
Syncope in supine position
Correct Answer
C. Frequent recurrence and prolonged historyExplanation
Cardiac syncope refers to fainting episodes caused by a problem with the heart. Elderly individuals and those with structural heart disease are more likely to experience cardiac syncope due to age-related changes in the cardiovascular system and underlying heart conditions. Syncope in the supine position is also suggestive of cardiac syncope as it may be caused by a decrease in blood flow to the brain. However, frequent recurrence and prolonged history are not typically associated with cardiac syncope. Instead, these symptoms may indicate other causes such as vasovagal syncope or neurological conditions.Rate this question:

34 years old male patient with recent history fracture hip had sudden onset of breathlessness and presyncope. ECG is showing sinus tachycardia. Probable diagnosis is
- A.
Myocardial infarction
- B.
Pneumonia
- C.
Pulmonary thromboembolism
- D.
None of the above
Correct Answer
C. Pulmonary thromboembolismExplanation
The sudden onset of breathlessness and presyncope in a patient with a recent history of hip fracture suggests a possible pulmonary thromboembolism. Pulmonary thromboembolism occurs when a blood clot, usually from the lower extremities, travels to the lungs, causing a blockage in the pulmonary arteries. This can lead to symptoms such as shortness of breath, chest pain, and a rapid heart rate (sinus tachycardia). Given the patient's clinical presentation and ECG findings, pulmonary thromboembolism is the most likely diagnosis.Rate this question:

Prophylaxis for prevention of endocarditis is suggested in all except:
- A.
Annuloplasty rings and chords used for valve repair
- B.
Repaired CHD with residual shunts or valvular regurgitation at the site adjacent to prosthetic patch
- C.
Valvular regurgitation due to structurally abnormal valve
- D.
Repaired CHD with occlusion device during first six months after procedure
- E.
None of the above
Correct Answer
C. Valvular regurgitation due to structurally abnormal valveExplanation
Prophylaxis for prevention of endocarditis is suggested in patients with certain conditions that increase the risk of developing infective endocarditis. These conditions include prosthetic heart valves, repaired congenital heart defects (CHD) with residual shunts or valvular regurgitation at the site adjacent to a prosthetic patch, and repaired CHD with an occlusion device during the first six months after the procedure. Valvular regurgitation due to a structurally abnormal valve is not specifically mentioned as a condition requiring prophylaxis for endocarditis. Therefore, the correct answer is "Valvular regurgitation due to structurally abnormal valve."Rate this question:

Antibiotic prophylaxis is indicated in all except
- A.
Tooth extraction
- B.
Tonsillectomy
- C.
Skin or soft tissue surgery
- D.
Vaginal or caesarean delivery
Correct Answer
D. Vaginal or caesarean deliveryExplanation
Antibiotic prophylaxis is the administration of antibiotics to prevent infection in certain high-risk procedures. Tooth extraction, tonsillectomy, and skin or soft tissue surgery are all invasive procedures that can introduce bacteria into the bloodstream. Antibiotic prophylaxis is recommended in these cases to prevent the development of infections. However, vaginal or caesarean delivery is a natural process that does not involve the same level of invasiveness as the other procedures listed. Therefore, antibiotic prophylaxis is not indicated in vaginal or caesarean delivery.Rate this question:

Combination of antihypertensive drugs to be avoided
- A.
ACEI and ARB
- B.
ACEI and Diuretics
- C.
CCB and ACEI
- D.
Beta blocker and diuretic
- E.
Beta blocker and CCB
Correct Answer
A. ACEI and ARBExplanation
Combining ACE inhibitors (ACEI) and angiotensin receptor blockers (ARB) should be avoided because both medications work on the same pathway to lower blood pressure. ACE inhibitors block the enzyme that converts angiotensin I to angiotensin II, while ARBs block the receptor for angiotensin II. Using both medications together can lead to an excessive decrease in blood pressure, potentially causing dizziness, fainting, or other adverse effects. Therefore, it is recommended to avoid the combination of ACE inhibitors and ARBs.Rate this question:

Miss F is 18 years old presented with breathlessness on exertion since 5 years and has admission for heart failure twice. ECG showed sinus rhythm and left atrial enlargement. 2D Echo was suggestive of severe mitral stenosis and no LA clots (Wilkinson’s score- 6). Treatment of choice is
- A.
Balloon mitral valvotomy
- B.
Open Mitral valvotomy
- C.
Closed mitral valvotomy
- D.
Mitral valve replacement
Correct Answer
A. Balloon mitral valvotomyExplanation
The patient is a young individual with severe mitral stenosis, left atrial enlargement, and a low risk of left atrial clots (Wilkinson's score-6). Balloon mitral valvotomy is the treatment of choice in this case. It is a minimally invasive procedure that involves inflating a balloon in the narrowed mitral valve to widen it and improve blood flow. This procedure is preferred over open mitral valvotomy or mitral valve replacement because it is less invasive and has a lower risk of complications.Rate this question:
