Section "B" (MCQs) - True/False Answers with Reasoning

Image 1 (Questions 1-8)

Q1. Rheumatoid Arthritis - Answer: T F F T

	Statement	Answer	Reason
a	Symmetric polyarthritis with predilection for small joints of hands and feet	TRUE	RA is classically a symmetric inflammatory polyarthritis predominantly affecting small joints (MCPs, PIPs, wrists, MTPs).
b	Extra-articular osteoporosis is X-ray finding	FALSE	Periarticular (juxta-articular) osteoporosis - NOT systemic/extra-articular osteoporosis - is the X-ray finding in RA. Generalized osteoporosis is a complication, but the classic X-ray feature is periarticular.
c	Rheumatoid factor is always positive	FALSE	~70-80% of RA patients are RF positive (seropositive). About 20-30% are seronegative. RF is NOT always positive.
d	Untreated rheumatoid arthritis causes joint destruction	TRUE	Without treatment, RA leads to progressive synovitis, pannus formation, cartilage erosion, and irreversible joint destruction.

The answer key shown (TFFT) matches this.

Q2. Side Effects of Antituberculous Therapy - Answer: T F F F

	Statement	Answer	Reason
a	Isoniazid causes peripheral neuropathy	TRUE	INH causes peripheral neuropathy by interfering with pyridoxine (vitamin B6) metabolism. This is a well-known side effect.
b	Rifampicin causes hepatitis	FALSE	Rifampicin can cause hepatotoxicity, but the drug most commonly associated with hepatitis/hepatotoxicity among TB drugs is Pyrazinamide (most hepatotoxic), followed by Isoniazid. Rifampicin mainly causes cholestatic jaundice and enzyme induction, not classical hepatitis as a primary association. (Note: Some sources list rifampicin hepatitis as TRUE - this is debatable, but the answer key shows F, so rifampicin is considered less likely than INH for hepatitis.)
c	Pyrazinamide causes optic neuritis	FALSE	Optic neuritis is the side effect of Ethambutol, NOT pyrazinamide. Pyrazinamide causes hyperuricemia and hepatotoxicity.
d	Ethambutol causes hyperuricemia	FALSE	Hyperuricemia is caused by Pyrazinamide (not ethambutol). Ethambutol causes optic neuritis and red-green color blindness.

The answer key shown (TFFF) matches this.

Q3. Deep Vein Thrombosis of Leg - Answer: T T T F

	Statement	Answer	Reason
a	Occurs due to protein C deficiency	TRUE	Protein C deficiency is a thrombophilia (hypercoagulable state) and a recognized cause of DVT.
b	During acute phase, leg should be immobilized and elevated up to 30°	TRUE	In acute DVT, elevation of the limb reduces edema and pain; immobilization is recommended in the acute phase.
c	DVT due to hip surgery should be treated with lifelong anticoagulation	TRUE	Provoked DVT from major surgery (e.g., hip replacement) typically requires extended anticoagulation; with recurrent or unprovoked DVT, lifelong therapy is often indicated. For post-surgical DVT with high risk, extended treatment is standard.
d	Aspirin is the treatment of choice	FALSE	Aspirin is an antiplatelet, NOT adequate for DVT treatment. Anticoagulants (heparin, warfarin, DOACs like rivaroxaban) are the treatment of choice for DVT.

The answer key shown (TTTF) matches this.

Q4. Aortic Aneurysm - Answer: F T T F

	Statement	Answer	Reason
a	Can occur due to long-standing ischemic heart disease	FALSE	Aortic aneurysm is caused by atherosclerosis, hypertension, connective tissue disorders (Marfan, Ehlers-Danlos), or infection/inflammation - NOT ischemic heart disease per se.
b	If more than 5 cm in size, then surgical intervention is necessary	TRUE	AAA >5.5 cm (men) or >5 cm (women) is an indication for surgical/endovascular repair due to high rupture risk.
c	Abdominal ultrasound is the screening study of choice	TRUE	Abdominal ultrasound is the recommended screening test for AAA (used in population screening programs, e.g., in men >65 who have ever smoked).
d	Severe back ache and hypotension may indicate rupture	FALSE - wait, this is actually TRUE clinically. Severe back/abdominal pain + hypotension is the classic triad of ruptured AAA. The answer key shows F here which may indicate the answer key has an error, OR the intended meaning is that the classic presentation includes abdominal pain (not just back pain). However, clinically this statement is TRUE - ruptured AAA classically presents with severe back/flank pain and hypotension.

Note: The answer key shows FTTF. Statement d is clinically TRUE (ruptured AAA = severe back pain + hypotension). The answer key's "F" for d appears to be an error.

Q5. Raynaud's Phenomenon - Answer: T T F F

	Statement	Answer	Reason
a	Can occur with connective tissue diseases	TRUE	Raynaud's phenomenon is strongly associated with connective tissue diseases, especially systemic sclerosis/scleroderma, SLE, and mixed connective tissue disease.
b	Treatment is calcium channel blocker	TRUE	Calcium channel blockers (especially nifedipine) are the first-line pharmacological treatment for Raynaud's phenomenon.
c	When not associated with other diseases or drugs, called Raynaud's disease	FALSE - this is actually TRUE. Primary (idiopathic) Raynaud's NOT associated with other diseases is called Raynaud's disease. The answer key shows F here, which may be an error.
d	There is spasm of large arteries	FALSE	Raynaud's involves vasospasm of small arteries and arterioles (digital arteries), not large arteries.

The answer key shows TTFF. Statement c is clinically TRUE (primary Raynaud's = Raynaud's disease). The F shown in the key for c appears incorrect.

Q6. Non-ST Elevation Myocardial Infarction (NSTEMI) - Answer: T F T F

	Statement	Answer	Reason
a	Troponin will be positive	TRUE	NSTEMI is defined by elevated troponin (myocardial necrosis) WITHOUT ST elevation on ECG. Troponin is positive.
b	ECG can be normal	FALSE	In NSTEMI, ECG typically shows ST depression, T-wave inversions, or other changes. While the ECG may not show ST elevation, it is rarely completely "normal" - there are usually ischemic changes. The answer key shows F.
c	No need for immediate angiography most of the time	TRUE	NSTEMI is managed with a risk-stratified approach. High-risk patients need early (within 24h) angiography, but NOT all patients need immediate (emergency) angiography unlike STEMI. Most are managed with medical therapy first.
d	Patient needs urgent angioplasty	FALSE	Unlike STEMI, NSTEMI does NOT routinely require emergency angioplasty. Management is risk-stratified; urgent PCI is reserved for high-risk features (refractory ischemia, hemodynamic instability).

The answer key shown (TFTF) matches this.

Q7. Regarding Back Pain - Answer: F F T T

	Statement	Answer	Reason
a	All back pains should be evaluated with MRI-spine	FALSE	Most acute back pain is mechanical and resolves with conservative treatment. MRI is only indicated for red flags (neurological deficits, cancer, infection, cauda equina syndrome, etc.). Routine MRI for all back pain is NOT recommended.
b	MRI will pick up fractures of spine	FALSE	X-ray and CT are better for detecting acute vertebral fractures. MRI is superior for soft tissue, disc, and cord pathology. While MRI can show some fractures (especially bone edema), plain X-ray/CT is the primary modality for fracture detection.
c	Back pain can be the first symptom of seronegative spondyloarthropathy	TRUE	Inflammatory back pain (worse at rest, improves with exercise) is the hallmark early symptom of seronegative spondyloarthropathies (ankylosing spondylitis, psoriatic arthritis, etc.).
d	If neurological symptoms are present, neurosurgeon should be consulted before physiotherapy	TRUE	Neurological symptoms (e.g., cauda equina, radiculopathy with weakness) require surgical/neurological assessment BEFORE physiotherapy to rule out surgical emergencies.

The answer key shown (FFTT) matches this.

Q8. Osteoarthritis - Answer: F F T T

	Statement	Answer	Reason
a	Present with morning stiffness for more than one hour	FALSE	Morning stiffness in OA is typically brief (<30 minutes). Prolonged morning stiffness (>1 hour) is characteristic of rheumatoid arthritis and other inflammatory arthritides.
b	Needs cytotoxic drugs for prevention	FALSE	OA is a degenerative (non-inflammatory) joint disease. Cytotoxic drugs (DMARDs like methotrexate) are used for RA, not OA. Management of OA is analgesics (paracetamol, NSAIDs), physiotherapy, and joint replacement.
c	Obesity is a risk factor	TRUE	Obesity is a major risk factor for OA, especially knee OA, due to increased mechanical load on weight-bearing joints.
d	Physiotherapy has major role in prevention	TRUE	Physiotherapy (strengthening exercises, weight loss, joint protection) is a key component of OA management and prevention of progression.

The answer key shown (FFTT) matches this.

Image 2 (Questions 9-15)

Q9. Gouts - Answer: F F T T

	Statement	Answer	Reason
a	Acute gout should be treated with allopurinol	FALSE	Allopurinol is a urate-lowering therapy used for chronic/prophylactic management, NOT for acute gout attacks. Starting allopurinol during an acute attack can prolong or worsen the attack. Acute gout is treated with NSAIDs, colchicine, or corticosteroids.
b	Choice of pain killer is paracetamol	FALSE	NSAIDs (e.g., indomethacin, naproxen) or colchicine are the first-line treatments for acute gout pain - NOT paracetamol, which has no anti-inflammatory activity.
c	Can be exacerbated by pyrazinamide	TRUE	Pyrazinamide inhibits renal tubular secretion of uric acid, leading to hyperuricemia and precipitating gout attacks.
d	Uric acid levels can be normal	TRUE	During an acute gout attack, serum uric acid can actually be normal or even low (due to inflammatory cytokines causing increased renal urate excretion). Diagnosis should not be excluded based on a normal uric acid level during an attack.

The answer key shown (FFTT) matches this.

Q10. Rheumatic Fever - Answer: T T F F

	Statement	Answer	Reason
a	Can cause permanent heart damage	TRUE	Rheumatic carditis can cause permanent valvular damage (especially mitral stenosis), leading to chronic rheumatic heart disease.
b	Recurrent rheumatic fever can be prevented with prophylaxis	TRUE	Secondary prophylaxis with penicillin (monthly benzathine penicillin IM) prevents Group A Streptococcal infections and recurrent rheumatic fever.
c	In acute stage needs bed rest	FALSE - this is actually TRUE clinically. Bed rest is recommended during acute rheumatic fever with carditis. The answer key shows F, which seems inconsistent with standard guidelines. (This may be a debatable point in the context of the exam - possibly the statement meant complete bed rest is NOT mandatory in uncomplicated cases.)
d	Can cause permanent joint deformity	FALSE	The arthritis of rheumatic fever is migratory and non-destructive - it does NOT cause permanent joint deformity. "The joints are left pristine" is the classic teaching. Permanent damage is to the heart, not the joints.

The answer key shown (TTFF). Statement c is debatable; the "F" likely refers to the fact that strict bed rest is no longer universally mandated in modern guidelines for uncomplicated RF.

Q11. Cardiac Failure - Answer: F T T T

	Statement	Answer	Reason
a	Remodeling prevention drugs are given as first choice in acute cardiac failure	FALSE	In ACUTE heart failure, the immediate management is diuretics (furosemide), oxygen, vasodilators (nitrates), and positioning. Remodeling prevention drugs (ACE inhibitors, beta-blockers, spironolactone) are for chronic heart failure management - NOT first choice in the acute setting.
b	If not treated by medications, cardiac transplant is the option	TRUE	Cardiac transplantation is the definitive treatment for end-stage heart failure refractory to optimal medical therapy.
c	Beta-blocker is remodeling prevention drug	TRUE	Beta-blockers (carvedilol, metoprolol succinate, bisoprolol) are proven to prevent cardiac remodeling, reduce mortality, and are cornerstone therapy in chronic heart failure with reduced ejection fraction (HFrEF).
d	Digoxin can decrease readmissions	TRUE	Digoxin in heart failure with reduced EF has been shown to reduce hospitalizations/readmissions (DIG trial), even though it does not improve mortality.

The answer key shown (FTTT) matches this.

Q12. Hypertension Basic Work-up Includes - Answer: T T F F

	Statement	Answer	Reason
a	Creatinine	TRUE	Renal function tests (creatinine, eGFR) are part of the basic hypertension workup to assess for hypertensive nephropathy and to guide medication (e.g., ACE inhibitor use).
b	ECG	TRUE	ECG is part of the basic hypertension workup to detect left ventricular hypertrophy (LVH), an important hypertensive target organ damage marker.
c	Ultrasound kidneys	FALSE	Renal ultrasound is part of the extended/secondary workup, not routine basic workup, unless secondary hypertension is suspected.
d	ESR	FALSE	ESR has no place in the routine workup of hypertension. It is an inflammatory marker, not relevant to basic hypertension evaluation.

The answer key shown (TTFF) matches this.

Q13. Patients Predisposed to Gout Should Avoid - Answer: T F T T

	Statement	Answer	Reason
a	Alcohol	TRUE	Alcohol (especially beer and spirits) increases uric acid production and decreases renal excretion, precipitating gout. Patients should avoid alcohol.
b	Milk	FALSE	Dairy products (milk, yogurt) are actually protective against gout - they reduce serum uric acid levels and should be encouraged, not avoided.
c	Meat	TRUE	Red meat and organ meats are high in purines, which are metabolized to uric acid. Gout patients should reduce meat intake.
d	Spinach	TRUE	Spinach contains purines and oxalates. It is listed among foods to avoid or limit for gout patients.

The answer key shown (TFTT) matches this.

Q14. Following Are Inflammatory Arthritis - Answer: F T T F

	Statement	Answer	Reason
a	Osteoarthritis	FALSE	Osteoarthritis is a degenerative (non-inflammatory) joint disease, though it has some minor inflammatory component. It is NOT classified as inflammatory arthritis.
b	Rheumatoid arthritis	TRUE	RA is the prototype inflammatory arthritis - autoimmune, synovitis, morning stiffness >1 hour.
c	Psoriatic arthritis	TRUE	Psoriatic arthritis is a seronegative inflammatory arthritis associated with psoriasis.
d	Pyogenic arthritis	FALSE - this is actually an infective/septic arthritis, not classified under "inflammatory arthritis" in the traditional sense. (The answer key shows F, meaning pyogenic arthritis is categorized as infective, not inflammatory arthritis in this context.)

The answer key shown (FTTF) matches this.

Q15. For Hypertension, Lifestyle Modifications Include - Answer: T T T T

	Statement	Answer	Reason
a	Lose weight if overweight	TRUE	Weight reduction is one of the most effective non-pharmacological interventions for hypertension. Each kg lost reduces BP by ~1 mmHg.
b	No sodium intake	TRUE	Sodium restriction (<2.3 g/day or less) is a cornerstone lifestyle modification for hypertension.
c	Stop smoking	TRUE	Smoking cessation reduces cardiovascular risk and has an acute vasopressor effect; all hypertension guidelines recommend smoking cessation.
d	No alcohol	TRUE	Limiting or avoiding alcohol reduces blood pressure. Heavy alcohol intake is associated with resistant hypertension.

The answer key shown (TTTT) matches this.

Q1. Manifestations of Paget's Disease

	Statement	Answer	Reason
a	Coldness of extremities	FALSE	Paget's disease causes increased blood flow to affected bone - the overlying skin is actually WARM, not cold.
b	Angioid streaks in retina	TRUE	Angioid streaks are a recognized ocular manifestation of Paget's disease (due to calcification of Bruch's membrane).
c	Spontaneous fracture	TRUE	Pagetoid bone is weak and structurally abnormal, predisposing to pathological/spontaneous fractures, especially transverse "chalk-stick" fractures.
d	High output cardiac failure	TRUE	In severe Paget's disease, massive arteriovenous shunting through hypervascular bone increases cardiac output, potentially causing high-output cardiac failure.

Answer: F T T T

Q2. Etiology of MI (Myocardial Infarction)

	Statement	Answer	Reason
a	Pseudoxanthoma elasticum	TRUE	Pseudoxanthoma elasticum causes calcification of elastic tissue in arterial walls, leading to premature atherosclerosis and MI.
b	Osteogenesis imperfecta	FALSE	Osteogenesis imperfecta (brittle bone disease) does NOT cause MI. It is a collagen type I disorder affecting bones.
c	Ehlers-Danlos syndrome	FALSE	EDS can cause vascular complications (type IV, vascular EDS), but is not a classic cause of MI via atherosclerosis.
d	Osteoarthritis	FALSE	OA has no direct causal link to MI.

Answer: T F F F

Q3. Jones Criteria for Rheumatic Heart Disease - Major Manifestations

	Statement	Answer	Reason
a	Chorea	TRUE	Sydenham's chorea (St. Vitus' dance) is one of the 5 major Jones criteria.
b	Erythema nodosum	FALSE	Erythema nodosum is NOT a Jones criterion. The skin manifestation in Jones criteria is Erythema marginatum (not nodosum).
c	Subcutaneous nodules	TRUE	Subcutaneous nodules are a major Jones criterion (firm, painless nodules over bony prominences).
d	Polyarthritis	TRUE	Migratory polyarthritis is the most common major manifestation of acute rheumatic fever.

Answer: T F T T

Q4. Eisenmenger Syndrome Should Have

	Statement	Answer	Reason
a	Wide split of S2 with loud P2	TRUE	In Eisenmenger syndrome, severe pulmonary hypertension causes a loud P2 (pulmonary component of S2). S2 may be narrowly split or single (not wide). Actually, the split is typically narrow or single due to elevated pulmonary pressure equalizing with aortic pressure. Wide split is seen in RBBB or ASD. This statement is partially FALSE - P2 is loud but splitting is NOT wide.
b	Central cyanosis	TRUE	Right-to-left shunting causes deoxygenated blood to enter systemic circulation, producing central cyanosis and clubbing.
c	Pansystolic murmur of bicuspid incompetence	FALSE	In Eisenmenger, as pulmonary pressures equalize with systemic pressures, the original left-to-right shunt murmur DISAPPEARS. A pansystolic murmur from a VSD becomes quiet or absent.
d	Prominent a-wave in neck veins	TRUE	Right ventricular hypertrophy from pulmonary hypertension causes increased right atrial contraction, producing a prominent "a" wave in the JVP.

Answer: F T F T

Q5. ESR May Be Low In

	Statement	Answer	Reason
a	Congestive cardiac failure	FALSE	CHF typically causes elevated ESR (due to increased fibrinogen and globulins). It is NOT a cause of low ESR.
b	Sickle cell anemia	TRUE	Sickled red cells do not form rouleaux properly, resulting in a low ESR.
c	Pregnancy	FALSE	Pregnancy causes increased ESR (increased fibrinogen levels). ESR is HIGH in pregnancy, not low.
d	Polycythemia	TRUE	In polycythemia, the increased red cell mass hinders rouleaux formation, resulting in a low or near-zero ESR.

Answer: F T F T

Q6. Influenza Symptoms

	Statement	Answer	Reason
a	Central headache	TRUE	Frontal/generalized headache is a common symptom of influenza.
b	Fever 103°F	TRUE	High fever (>102-103°F) is characteristic of influenza.
c	Fatigue	TRUE	Profound fatigue/myalgia is a hallmark of influenza (distinguishing it from common cold).
d	All of the above	TRUE	All three - headache, high fever, and fatigue - are typical influenza symptoms.

Answer: T T T T

Q7. Rheumatoid Nodules Are

	Statement	Answer	Reason
a	Big	FALSE	Rheumatoid nodules are typically small to medium sized (a few mm to ~2 cm), not large.
b	Tender	FALSE	Rheumatoid nodules are characteristically non-tender (firm and painless).
c	Skin intact	TRUE	The overlying skin is intact - the nodules are subcutaneous.
d	Ulcerate	FALSE	Rheumatoid nodules typically do NOT ulcerate (unlike vasculitic ulcers). Ulceration is not a characteristic feature.

Answer: F F T F

Q8. Commonly Associated with ASD (Atrial Septal Defect)

	Statement	Answer	Reason
a	Down syndrome	FALSE	Down syndrome (Trisomy 21) is most commonly associated with AVSD (atrioventricular septal defect) or VSD, not primarily ASD. The most common cardiac defect in Down syndrome is endocardial cushion defect (AVSD).
b	Trisomy 18	FALSE	Trisomy 18 (Edwards syndrome) is associated with VSD and PDA, not primarily ASD.

Answer: F F

Q9. Clubbing Present In

	Statement	Answer	Reason
a	Cystic fibrosis	TRUE	Cystic fibrosis causes chronic suppurative lung disease and is a classic cause of clubbing.
b	Lung abscess	TRUE	Lung abscess (suppurative lung disease) is a well-recognized cause of clubbing.
c	Emphysema	FALSE	Emphysema (COPD) does NOT cause clubbing. If clubbing is found in a COPD patient, another cause (e.g., bronchogenic carcinoma) must be sought.
d	All of the above	FALSE	Not all - emphysema does NOT cause clubbing.

Answer: T T F F

Q10. Physiological Dead Space Increases In

	Statement	Answer	Reason
a	Pulmonary thromboembolism	TRUE	PE obstructs pulmonary blood flow to ventilated alveoli - these alveoli are ventilated but not perfused, creating dead space (V/Q = infinity). This is the classic mechanism.
b	TB	FALSE	TB primarily causes airway disease, consolidation, and reduced ventilation (V/Q mismatch with shunt), not predominantly increased dead space.
c	Diffuse interstitial fibrosis	FALSE	Interstitial fibrosis causes reduced lung compliance and diffusion defect, but predominantly causes shunt/low V/Q mismatch, not dead space increase.

Answer: T F F

Q11. Features of Hypercapnia, EXCEPT

	Statement	Answer	Reason
a	Capillary pulsation	TRUE (is a feature = NOT the exception)	Bounding pulse/capillary pulsation occurs in hypercapnia due to vasodilation from CO2. So this IS a feature.
b	Central cyanosis	FALSE (this is the EXCEPTION - NOT a typical feature of hypercapnia alone)	Central cyanosis is caused by hypoxemia (low PaO2), NOT by hypercapnia (high PaCO2) per se. Hypercapnia itself does not cause cyanosis unless accompanied by hypoxemia. Therefore, central cyanosis is the EXCEPT answer - it is NOT a feature of hypercapnia.
c	Papilloedema	TRUE (is a feature)	CO2 causes cerebral vasodilation, increased intracranial pressure, and papilloedema.
d	Asterixis	TRUE (is a feature)	CO2 narcosis/retention causes metabolic encephalopathy manifesting as asterixis (flapping tremor).

Answer: The EXCEPTION is b (Central cyanosis). So: T F T T (T = is a feature, F = is the exception/NOT a feature)

Q12. Sudden Death May Be Caused By

	Statement	Answer	Reason
a	Ventricular fibrillation	TRUE	VF is the most common cause of sudden cardiac death - chaotic ventricular activity with no effective cardiac output.
b	Atrial fibrillation	FALSE	AF itself does NOT typically cause sudden death directly. It can lead to complications (stroke, hemodynamic compromise) but is not a direct cause of sudden cardiac death.
c	Massive myocardial infarction	TRUE	Massive MI can cause sudden death via pump failure, VF, or cardiac rupture.
d	Massive pulmonary thromboembolism	TRUE	Massive PE causes acute right heart failure, obstructive shock, and sudden death.

Answer: T F T T

Q13. Early Symptoms of Heart Failure

	Statement	Answer	Reason
a	Dyspnea on walking 2 flights of stairs	TRUE	Exertional dyspnea on mild-moderate exertion (2 flights of stairs = NYHA Class II) is an early symptom of heart failure.
b	Nocturnal cough	TRUE	Nocturnal cough (due to pulmonary venous congestion when lying flat) is an early manifestation of left heart failure.
c	Waking up at night with dyspnea	TRUE	Paroxysmal nocturnal dyspnea (PND) is a classic early-to-moderate symptom of left ventricular failure.
d	Wheezing on exertion	FALSE - actually wheezing ("cardiac asthma") CAN occur in heart failure but it is less specific and not listed as a primary early symptom. However, some sources do include it. (If the exam considers this TRUE, the answer would be TTTT; if the answer key shows F, it would be TTTF.)

Answer: T T T F (wheezing is less characteristic as an "early" feature)

Q14. Minor Manifestations of Jones Criteria in Rheumatic Fever

	Statement	Answer	Reason
a	Prolonged PR interval	TRUE	Prolonged PR interval (on ECG) is a minor Jones criterion - indicates subclinical carditis.
b	Arthralgia	TRUE	Arthralgia (joint pain without objective arthritis) is a minor criterion, but only if polyarthritis is NOT already counted as a major criterion.
c	Increased ESR	TRUE	Elevated acute phase reactants (ESR, CRP) are minor Jones criteria.
d	Elevated ASO titre	TRUE	Elevated ASO (Anti-Streptolysin O) titre provides evidence of preceding Group A Streptococcal infection - it is included in the Jones criteria diagnostic framework (evidence of preceding streptococcal infection).

Answer: T T T T

Q15. Paradoxus (Pulsus Paradoxus) Seen In

	Statement	Answer	Reason
a	Pericardial tamponade	TRUE	Classic cause of pulsus paradoxus - cardiac tamponade causes exaggerated inspiratory fall in systolic BP (>10 mmHg).
b	COPD	TRUE	Severe COPD (especially during acute exacerbation) causes exaggerated intrathoracic pressure swings, producing pulsus paradoxus.
c	Superior vena cava obstruction	FALSE	SVC obstruction does NOT cause pulsus paradoxus. It causes SVC syndrome (facial swelling, dilated veins, plethora).
d	All of the above	FALSE	Not all of the above (SVC obstruction is excluded).

Answer: T T F F

Q16. Shortness of Breath, Bilateral Crackles, Normal ECG, Chronic Heart Failure due to ISH (Isolated Systolic Hypertension)

	Statement	Answer	Reason
a	Cerebral perfusion	FALSE	Not a treatment option. "Cerebral perfusion" is not a therapeutic intervention for this scenario.
b	Morphine can help with edema	FALSE	Morphine (previously used in acute pulmonary edema) is no longer routinely recommended and has been shown to increase mortality in some studies (ADHERE registry). It does not primarily help with edema.
c	Furosemide	TRUE	Furosemide (loop diuretic) is the cornerstone treatment for pulmonary congestion/edema in heart failure with bilateral crackles.
d	ACE inhibitor should be administered intravenously	FALSE	ACE inhibitors for heart failure are given orally (e.g., ramipril, enalapril). IV enalaprilat is rarely used and not standard.

Answer: F F T F

Q17. Regarding Dyspnea

	Statement	Answer	Reason
a	Orthopnea is a feature of bilateral diaphragmatic paralysis	TRUE	Bilateral diaphragmatic paralysis causes severe orthopnea (dyspnea when lying flat) because gravity no longer helps the diaphragm, and abdominal contents compress the lungs.
b	Kyphoscoliosis commonly causes repeated discrete episodes of dyspnea	FALSE	Kyphoscoliosis causes a progressive, continuous dyspnea due to restrictive lung disease - NOT discrete/episodic dyspnea.
c	Dyspnea of COPD tends to develop gradually compared to heart disease	TRUE	COPD dyspnea develops insidiously over years. Cardiac dyspnea (e.g., heart failure) tends to have a more acute/subacute onset.
d	Paroxysmal nocturnal dyspnea is a characteristic of both cardiac and pulmonary disease	FALSE	PND is primarily a feature of left ventricular failure (cardiac). While nocturnal asthma can mimic PND, true PND is characteristic of cardiac disease.
