🏥 MD GENERAL MEDICINE FINAL PRACTICAL — 3-DAY TOTAL BATTLE PLAN

RGUHS Format | Long Case + Short Case + Spotters + Viva

Senior Professor of Internal Medicine & Chief Examiner speaking. Listen carefully.

BEFORE ANYTHING ELSE — THE EXAMINER'S MINDSET

You are not being tested on knowledge alone. You are being assessed on whether you are safe to be an independent physician. Every examiner asks: "Would I trust this person to manage my family member?"

The 4 things that earn DISTINCTION:

Systematic, unhurried, confident examination technique
Flawless structured case presentation with clinical reasoning
Ability to defend findings with pathophysiology
Honest, intelligent handling of uncertainty

The 4 things that cause FAILURE:

Skipping steps in examination (unsafe = fail)
Presenting without findings (talking without examining)
Wrong anatomical reasoning
Panicking when questioned

DAY 1 (TODAY - MONDAY EVENING + NIGHT)

CARDIOLOGY + RESPIRATORY

MODULE 1: THE LONG CASE MASTER FRAMEWORK

This applies to EVERY long case regardless of system. Internalize this skeleton first.

THE UNIVERSAL LONG CASE BLUEPRINT

PHASE 1 — ENTERING THE ROOM (First 60 seconds — examiner is watching)

What to do:

Knock, enter, introduce yourself: "Good morning, I am Dr. [Name], a postgraduate student. I've been asked to examine you today. Is that alright?"
Wash hands / use sanitizer visibly
Adjust patient position BEFORE starting
Ensure adequate exposure with dignity maintained
Check lighting
Stand on the patient's RIGHT side throughout

What the examiner sees: Your professionalism, rapport, and whether you follow a system.

PHASE 2 — HISTORY TAKING (10-12 minutes for long case)

Use the SOCRATES + SYSTEM REVIEW framework:

Chief Complaint → Site, Onset, Character, Radiation, Associated symptoms, Timing, Exacerbating/relieving factors, Severity

Then systematically cover:

Past history (same disease, related diseases, hospitalizations, procedures)
Drug history (ALL medications including OTC, herbal, inhalers, insulin)
Allergy history
Family history (relevance to diagnosis)
Social history (smoking pack-years, alcohol units/week, occupation, TB contacts, travel)
Review of systems (screen every system)

PHASE 3 — GENERAL EXAMINATION (2 minutes — do NOT skip anything)

The RGUHS Examiner's Checklist - General Examination:

Stand back, observe the whole patient first. Then systematically:

1. Built / Nutrition / Appearance
2. Consciousness (GCS if relevant)
3. Cooperative / Oriented
4. Pallor (conjunctival pallor — pull lower eyelid)
5. Icterus (scleral icterus — lift upper eyelid)
6. Cyanosis (peripheral: nail beds/lips; central: tongue)
7. Clubbing (Grade I-IV — Schamroth's sign)
8. Lymphadenopathy (cervical, axillary, inguinal — describe: site, size, consistency, tenderness, matted/discrete, fixity)
9. Edema (pitting/non-pitting, extent — ankle/sacral/ascites)
10. JVP (right IJV, 45°, cm above sternal angle; waveforms)
11. Pulse (Rate, rhythm, volume, character, all peripheral pulses)
12. Blood pressure (both arms if aortic dissection/coarctation suspected)
13. Temperature
14. Respiratory rate
15. SPO2 if available

Examiner trap: Missing JVP in a cardiac patient = automatic mark deduction. Missing peripheral pulses in a hypertensive = dangerous omission.

PHASE 4 — SYSTEMIC EXAMINATION (system-specific, detailed below)

PHASE 5 — CASE PRESENTATION (5 minutes — this is where marks are won or lost)

Model Opening Line: "I examined Mr./Mrs. [Name], a [age]-year-old [gender], [occupation], residing in [place], who presented with [chief complaint(s)] of [duration]."

The 6-Part Presentation Structure:

Patient identification + chief complaints
Relevant history summary (2-3 sentences)
General examination findings
Systemic examination findings (positive and relevant negatives)
Summary and clinical reasoning
Provisional diagnosis + differentials + plan

Never say "I THINK." Say "On examination, I FOUND." Never say "Maybe it could be." Say "The most likely diagnosis is X, supported by findings A, B, C."

MODULE 2: CARDIOLOGY — COMPLETE BEDSIDE EXAMINATION

APPLIED ANATOMY PEARLS (Examiner-level)

Mitral valve: best heard at apex (5th ICS, MCL) — transmitted to axilla
Aortic valve: best heard at 2nd ICS, right sternal border — transmitted to carotids
Pulmonary valve: 2nd ICS, left sternal border
Tricuspid valve: 4th ICS, left sternal border — transmitted to xiphoid
Erb's point (3rd ICS, LSB): aortic regurgitation heard best here

CARDIOVASCULAR EXAMINATION — STEP BY STEP

INSPECTION (from foot of the bed):

• Dyspnea at rest? (orthopnea — how many pillows?)
• Malar flush (mitral stenosis)
• Cyanosis — central or peripheral
• Facial features: Down syndrome (ASD/VSD/AVSD), Marfan's, Turner's
• Precordial bulge (RV enlargement in children)
• Visible apex beat / precordial pulsations
• Carotid pulsations ("Corrigan's pulsation" in AR)
• Distended neck veins
• Peripheral edema
• Look at hands: clubbing, splinter hemorrhages, Osler's nodes, Janeway lesions, Quincke's sign

PULSE ASSESSMENT (DO THIS BEFORE PRECORDIAL EXAM):

Radial pulse: Rate, rhythm, volume, character
Then ALL peripheral pulses:
• Brachial (both arms), Carotid (palpate ONE side at a time — NEVER bilateral simultaneously — causes carotid sinus pressure → syncope)
• Femoral, Popliteal, Posterior tibial, Dorsalis pedis
Radio-femoral delay → coarctation of aorta
Radio-radial inequality → aortic dissection, cervical rib, Takayasu's

Pulse characters to know:

Pulse	Description	Disease
Bounding/Collapsing	Rapid upstroke, collapses quickly	AR, Thyrotoxicosis, PDA, AVM
Plateau/Parvus et tardus	Slow rising, sustained	Aortic Stenosis
Bisferiens	Double peak	HOCM + AR
Paradoxical (Pulsus paradoxus)	>10 mmHg fall on inspiration	Cardiac tamponade, severe asthma
Alternans	Alternating strong/weak	Severe LV failure
Dicrotic	Double peak (one in diastole)	Low cardiac output states

JVP ASSESSMENT:

Position: 45°
Use RIGHT IJV (more direct route to RA)
Identify: Pulsation obliterated by pressure (vs carotid which is not)
Measure: Vertical height above sternal angle (normal <4 cm = <9 cm above RA)
Waveforms:
  'a' wave = atrial contraction (absent in AF, giant in TS, tricuspid atresia)
  'c' wave = tricuspid closure (usually invisible)
  'v' wave = venous filling while TV closed (giant in TR)
  'x' descent = atrial relaxation + RV systole
  'y' descent = tricuspid opening
Kussmaul's sign: JVP RISES on inspiration → constrictive pericarditis, RV failure, cardiac tamponade

PRECORDIAL EXAMINATION:

INSPECTION:

Apex beat location (normally 5th ICS, MCL)
Visible pulsations: apical, parasternal, epigastric
Precordial bulge, scars (sternotomy, lateral thoracotomy), pacemaker/ICD bulge, implanted devices

PALPATION:

Step 1: Apex beat
  - Use flat of hand first, then fingertip
  - Localize: which ICS? MCL or lateral to it?
  - Character:
    • Normal: tapping, <2 cm, felt in 1 ICS
    • Heaving/Sustained: LV pressure overload (AS, HTN, AR chronic)
    • Hyperdynamic/Thrusting: LV volume overload (AR, MR acute)
    • Tapping: Palpable S1 = Mitral Stenosis
    • Diffuse/Displaced: Dilated cardiomyopathy
    • Double impulse: HOCM
    
Step 2: Parasternal heave (RV hypertrophy)
  - Palm at left sternal border, 3rd-5th ICS
  - Heave = RV enlargement (cor pulmonale, MS with PHT, ASD)
  
Step 3: Thrills
  - Systolic thrill at base (2nd ICS RSB) → AS
  - Systolic thrill at apex → MR
  - Diastolic thrill at apex → MS (rare)
  - Palpable P2 (2nd ICS LSB) → Pulmonary hypertension

AUSCULTATION — THE CORRECT SEQUENCE:

Always: Diaphragm for high-pitched sounds, Bell for low-pitched (S3, S4, MS rumble)

Sequence:
1. Mitral area (apex): S1 best
2. Tricuspid area (4th ICS LSB): S1, TR
3. Pulmonary area (2nd ICS LSB): S2 (P2 component), pulmonary sounds
4. Aortic area (2nd ICS RSB): S2 (A2 component), aortic sounds
5. Erb's point (3rd ICS LSB): AR early diastolic murmur

For EACH AREA note:
• S1: loud/soft/variable
• S2: normal/split/fixed split/paradoxical split/loud P2
• Additional sounds: S3, S4, opening snap, ejection click, pericardial rub
• Murmurs: Timing, Location, Grade, Radiation, Character, Effect of maneuvers

MURMUR GRADING (Levine Scale):

Grade 1: Barely audible (only with effort, quiet room)
Grade 2: Soft but easily heard
Grade 3: Loud, NO thrill
Grade 4: Loud + THRILL
Grade 5: Very loud, stethoscope partly off chest
Grade 6: Heard without stethoscope

Always describe murmur as: "A grade [X]/6 [systolic/diastolic] murmur, best heard at [location], radiating to [site], [crescendo-decrescendo/pansystolic/etc.], [what increases/decreases it]."

DYNAMIC AUSCULTATION — EXAMINER'S FAVOURITE:

Maneuver	What it does	What it helps identify
Left lateral position	Brings apex closer, accentuates mitral sounds	MS rumble, S3, S4
Sitting forward, end expiration	Brings base closer	AR early diastolic murmur
Standing → Squatting	Increases preload (venous return)	HOCM murmur decreases; AS increases
Squatting → Standing	Decreases preload	HOCM murmur increases
Valsalva (phase II)	Decreases venous return	HOCM murmur increases; AS/MR decrease
Inspiration	Right heart sounds increase	TR/PR murmurs louder
Expiration	Left heart sounds increase	MR/MS/AR louder

HIGH-YIELD CARDIAC SHORT CASES

SHORT CASE 1: MITRAL STENOSIS

CLASSIC FINDINGS:

Malar flush (mitral facies)
Tapping apex beat (not displaced)
Parasternal heave (RV enlargement from PHT)
Palpable P2 (loud P2)
Loud S1 (mobile valve)
Opening snap (OS) — high-pitched, early diastole, apex/4th ICS LSB (earlier OS = severe MS = shorter S2-OS interval)
Mid-diastolic rumbling murmur (MDM) — low-pitched, bell at apex, left lateral position, pre-systolic accentuation in sinus rhythm
Absent pre-systolic accentuation → AF

SEVERITY IN MITRAL STENOSIS:

Severe MS:
• MVA <1.0 cm² (Echo)
• S2-OS interval <0.08 sec (shorter = more severe)
• Longer duration of MDM = more severe
• Signs of PHT: loud P2, right parasternal heave, JVP elevated
• P mitrale on ECG (bifid P in II, biphasic in V1)
• AF (long-standing)
• Radiologically: straightening of left heart border, enlarged LA, kerley B lines

PRESENTATION LINE: "This patient has features of mitral stenosis — evidenced by the malar flush, tapping non-displaced apex beat, parasternal heave, palpable P2, loud S1 with an opening snap at 0.1 seconds after S2, and a grade 3/6 mid-diastolic rumbling murmur with presystolic accentuation at the apex, best heard in the left lateral position. The signs of pulmonary hypertension suggest severe disease. The most likely etiology is rheumatic heart disease."

SHORT CASE 2: AORTIC REGURGITATION

CLASSIC FINDINGS (eponymous signs — examiner loves these):

Sign	What	How
Corrigan's pulse	Collapsing/water-hammer pulse	Raise patient's arm — feel bounding collapse
De Musset's sign	Head bobbing with each beat	Observe
Quincke's sign	Capillary pulsation	Press fingernail to blanch, release slightly
Traube's sign	Pistol-shot femorals	Auscultate over femoral
Duroziez's sign	To-and-fro femoral bruit	Compress femoral partially with stethoscope
Müller's sign	Uvular pulsations	Ask patient to open mouth
Hill's sign	Popliteal SBP > brachial SBP by >20 mmHg	Severe AR

AUSCULTATION:

High-pitched, early diastolic, decrescendo murmur (EDM)
Best at Erb's point (3rd ICS LSB), patient sitting forward, end expiration
Austin Flint murmur: functional MDM at apex (AR jet hitting anterior mitral leaflet)
Soft/absent S2 (A2)
Displaced, hyperdynamic apex beat

SHORT CASE 3: HEART FAILURE

CLINICAL SIGNS BY TYPE:

LEFT HEART FAILURE:

Dyspnea, orthopnea, PND
Bilateral crackles (basal, fine, inspiratory — don't clear with cough)
S3 gallop (ventricular gallop) — at apex, with bell, left lateral
Pulsus alternans
Displaced apex beat (DCM pattern)
Elevated JVP in combined failure

RIGHT HEART FAILURE:

Elevated JVP with v-wave
Hepatomegaly (pulsatile in TR)
Ascites
Pedal edema (bilateral, pitting, dependent)
Parasternal heave

S3 vs S4:

S3: End of rapid filling, low-pitched, at apex, EARLY diastole → volume overload (HF, MR, VSD), normal in young/pregnancy
S4: Pre-systolic, due to atrial kick into stiff LV → pressure overload (HTN, AS, HCM, ischemia); ABSENT in AF

MODULE 3: RESPIRATORY — COMPLETE BEDSIDE EXAMINATION

RESPIRATORY EXAMINATION — STEP BY STEP

INSPECTION:

General:
• Dyspnea at rest, accessory muscle use (SCM, scalenes)
• Tracheal position (look and ask patient to swallow)
• Chest shape: barrel chest, pectus excavatum/carinatum, kyphoscoliosis, Harrison's sulcus
• Chest expansion (symmetrical/asymmetrical)
• Respiratory rate, rhythm, depth
• Use of accessory muscles, intercostal recession
• Hoover's sign (inward movement of lower ribs in hyperinflation)
• Any scars, sinuses, drains

Hands:
• Clubbing (causes: fibrosis, bronchiectasis, carcinoma, abscess, mesothelioma — NOT COPD, NOT asthma)
• Peripheral cyanosis
• Nicotine staining
• Fine tremor (CO2 retention — asterixis/flap)
• Wasting (Pancoast tumor — T1 wasting of small hand muscles)

Face:
• Central cyanosis (tongue)
• Horner's syndrome (ptosis, miosis, anhidrosis — Pancoast tumor)
• Pursed-lip breathing (COPD)
• Plethoric face (SVCO, polycythemia)

PALPATION:

Sequence:
1. Trachea: 2 fingers either side, is it central?
   → Deviated TOWARDS: collapse, fibrosis
   → Deviated AWAY: effusion (massive), tension pneumothorax, large goitre
   
2. Apex beat (confirms mediastinal shift)

3. Chest expansion:
   - Upper: hands on clavicles, thumbs meet in midline
   - Lower: hands wrap around chest, thumbs meet at midline spine
   - Normal: >5 cm at lower chest, symmetrical
   - Reduced on ONE side: effusion, pneumonia, collapse, pneumothorax, fibrosis (ipsilateral)
   - Reduced bilaterally: COPD, bilateral fibrosis, bilateral effusion

4. Vocal Fremitus (tactile):
   - Ulnar border of hand, compare side to side
   - Say "99" or "1, 1, 1"
   - INCREASED: consolidation (better transmission through solid)
   - DECREASED/ABSENT: effusion (fluid blocks), pneumothorax (air blocks), collapse (blocked bronchus)

PERCUSSION:

ALWAYS compare side to side, top to bottom
Technique: Middle finger of non-dominant hand PRESSED firmly into ICS, strike MIDDLE PHALANX with middle finger of dominant hand — wrist flick, not whole arm

Notes:
• Resonant: normal lung
• Dull: consolidation, collapse, fibrosis (relative dull)
• Stony dull: pleural effusion (percuss to find fluid level — dullness below, resonant above)
• Hyper-resonant: pneumothorax, emphysema
• Cardiac/liver dullness: know normal limits

Traube's space: 6th rib superiorly, midaxillary line laterally, left costal margin — Resonant normally (gas in fundus of stomach). DULL in: splenomegaly, left pleural effusion, large left pericardial effusion

Shifting dullness / fluid thrill: Ascites (for respiratory candidate = missed if forgotten)

AUSCULTATION:

Technique: Diaphragm only for lung sounds
Go: Apices → Compare side to side → Down the back → Axillae (DON'T FORGET AXILLAE)

Normal breath sounds:
• Vesicular: soft, rustling, inspiration > expiration, no pause — normal peripheral lung
• Bronchial: tubular, harsh, equal in-out with pause, heard over trachea/larynx normally

Breath sounds - what they mean:
• Bronchial breathing over lung parenchyma → consolidation (CAP, TB) / at upper border of effusion (rare)
• Reduced/absent → effusion, pneumothorax, collapse, obesity, COPD
• Amphoric breathing → large cavity (TB cavity, lung abscess)

Additional sounds:
• Fine crackles (crepitations): ILD (Velcro crackles), pulmonary edema, pneumonia (don't clear with cough)
• Coarse crackles: Bronchiectasis, secretions (clear with cough)
• Wheeze: Asthma, COPD, foreign body, cardiac (cardiac asthma = wheeze from pulmonary edema)
• Pleural rub: Dry pleurisy — leathery, end-inspiratory + early-expiratory, localized, doesn't clear with cough, cough accentuates

Vocal resonance (spoken "99"):
• Increased: consolidation
• Decreased: effusion, pneumothorax
• Whispering pectoriloquy: whispered "99" clearly heard → consolidation (highly specific)
• Aegophony (E→A change): at upper border of effusion

THE THREE MOST COMMON RESPIRATORY SHORT CASES

SHORT CASE 1: PLEURAL EFFUSION

Signs:

Trachea: deviated AWAY from effusion (large) or central (small-moderate)
Expansion: reduced on affected side
Tactile fremitus: ABSENT/reduced
Percussion: STONY DULL (most specific sign) — with horizontal upper border
Auscultation: Absent breath sounds, aegophony at upper border

Investigation first line: CXR (blunting of costophrenic angle >200-300 mL), US chest (most sensitive)

LIGHT'S CRITERIA (Transudates vs Exudates):

Exudate if ANY ONE of:

Pleural protein/Serum protein > 0.5
Pleural LDH/Serum LDH > 0.6
Pleural LDH > 2/3 upper limit of normal serum LDH

Transudate causes: Heart failure (bilateral), cirrhosis, nephrotic syndrome, hypothyroidism, Meigs' syndrome Exudate causes: Parapneumonic, malignancy, TB, PE, rheumatoid, SLE

Examiner question: "What is the commonest cause of bilateral pleural effusion?" → Heart failure

SHORT CASE 2: COPD/EMPHYSEMA

Classic Signs:

Barrel chest (AP = transverse diameter), Harrison's sulcus
Pursed lip breathing, accessory muscle use
Trachea: central or slightly elevated (emphysema - hyperinflated lungs push trachea up)
Expansion: reduced bilaterally
Percussion: bilateral hyper-resonance, obliterated cardiac + liver dullness
Breath sounds: vesicular but REDUCED
Prolonged expiration + expiratory wheeze
Coarse crackles if infection
JVP elevated + cor pulmonale signs if advanced

ABG in COPD exacerbation:

Type II respiratory failure: PaO2 <60, PaCO2 >45, pH <7.35 (compensated if pH normal with elevated HCO3)
Target SpO2 in COPD: 88-92% (not 95-100% — removes hypoxic drive)

SHORT CASE 3: CONSOLIDATION (Lobar Pneumonia)

Signs:

Trachea: central (or slightly towards if large area)
Expansion: reduced IPSILATERAL
Tactile fremitus: INCREASED
Percussion: DULL (not stony — contrast with effusion)
Auscultation: BRONCHIAL BREATHING + coarse crackles
Vocal resonance: INCREASED, whispering pectoriloquy present

SIGN DIFFERENTIATION TABLE — EXAMINER FAVOURITE

Sign	Effusion	Consolidation	Pneumothorax	Collapse	COPD
Trachea	Away (large)	Central	Away	Towards	Central
Expansion	Reduced	Reduced	Reduced	Reduced	↓ bilateral
Tactile fremitus	Absent	Increased	Absent	Absent	Reduced
Percussion	Stony dull	Dull	Hyper-resonant	Dull	Hyper-resonant
Breath sounds	Absent	Bronchial	Absent	Absent	Vesicular ↓
Vocal resonance	Absent	Increased	Absent	Absent	Reduced

Memorize this table. Examiners test it every year.

MODULE 4: ECG SPOTTERS — RAPID FIRE

The 10 ECGs you MUST be able to read in 60 seconds:

ECG READING SYSTEM (Never deviate):

"I will read this ECG systematically."

Rate (300/large squares between R-R)
Rhythm (regular? P before every QRS? PR interval constant?)
Axis (Lead I and aVF — normal: both positive)
P wave (present, morphology, duration <0.12s)
PR interval (0.12-0.20s)
QRS (duration <0.12s, morphology, any Q waves)
ST segment (elevation/depression — which leads)
T wave (upright/inverted, symmetric/asymmetric)
QTc interval
Overall diagnosis

STEMI patterns:

Inferior (II, III, aVF) → RCA
Anterior (V1-V4) → LAD
Lateral (I, aVL, V5-V6) → LCx
Posterior (tall R + ST depression in V1-V2, ST elevation in V7-V9) → RCA/LCx
RV infarct (ST elevation in V4R) → Check right-sided leads in every inferior MI

Examiner question: "Inferior STEMI — what else must you always look for?" → RV infarction (ST elevation in V4R). Management implication: avoid nitrates and diuretics (preload-dependent RV).

Other High-Yield ECGs:

AF: Absent P waves, irregularly irregular, fibrillatory baseline, variable QRS
SVT: Narrow complex, rate 150-250, P waves hidden or retrograde
VT: Broad complex (>0.12s), tachycardia, AV dissociation, fusion/capture beats, Brugada/Josephson criteria
LBBB: Broad QRS, M pattern V5-V6, W pattern V1 (WiLLiaM), ST changes discordant
RBBB: rSR' in V1, S wave in I and V6 (MaRRoW)
LVH: Sokolov-Lyon: SV1 + RV5 >35 mm; Cornell: RaVL + SV3 >28 mm (men)
Digoxin toxicity: Sagging ST ("reverse tick"), bradycardia, AV blocks, bidirectional VT
Hyperkalaemia: peaked T waves → PR prolongation → QRS widening → sine wave → VF
PE: S1Q3T3 (SI, QIII, T-inversion III) — RV strain, RBBB, sinus tachycardia

MODULE 5: CXR SPOTTERS — SYSTEMATIC READING

NEVER say "this CXR shows..." without first reading it systematically.

CXR READING SYSTEM (10 steps):

Patient details (name, date, position)
Technical quality (AP/PA, rotation — spinous process equidistant from clavicular heads, penetration — disc spaces visible, inspiration — 5-6 anterior ribs visible)
Airway (trachea central? carina angle? ET tube position?)
Bones (ribs — fractures, notching; spine; clavicles; shoulder)
Cardiac (size — CTR <0.5 in PA; shape; borders)
Diaphragm (right higher than left, normally; costophrenic angles clear; air under diaphragm?)
Effusion/Pleura (blunting of angles, pleural thickening, calcification)
Fields (zones — upper/middle/lower; infiltrates, masses, cavities)
Hilar shadows (density, size, bilateral enlargement)
Soft tissues (breast shadows, surgical emphysema, mastectomy, implants)

High-Yield CXR Patterns:

Pattern	Appearance	Diagnoses
Cardiomegaly + pulmonary edema	CTR >0.5, upper lobe diversion, bat-wing shadowing, Kerley B lines	Acute LVF/decompensated HF
Bilateral hilar lymphadenopathy	Bilateral symmetric hilar enlargement	Sarcoidosis (commonest), lymphoma, TB
Cavitation	Ring shadow with wall	TB (upper zone), abscess, Wegener's (now GPA), squamous cell CA, hydatid
Miliary pattern	Tiny 1-2 mm nodules throughout	Miliary TB (commonest), miliary malignancy, sarcoidosis
Honeycombing	Subpleural basal stacked cysts	UIP pattern (IPF)
Pleural effusion	Blunted costophrenic angle, meniscus sign, opacification
Consolidation	Homogeneous opacity, air bronchogram	Pneumonia, infarct
Pneumothorax	Absent lung markings, visible lung edge, collapsed lung

MODULE 6: VIVA QUESTIONS — CARDIOLOGY & RESPIRATORY

PROGRESSIVE VIVA — ANSWER BEFORE READING THE IDEAL ANSWER

Question 1 (Basic): "What is the significance of a collapsing pulse?"

→ Ideal Answer: "A collapsing or water-hammer pulse indicates increased pulse pressure due to either increased stroke volume or decreased peripheral vascular resistance. The most important causes at MD level are aortic regurgitation, where backflow into the LV during diastole causes the pressure to fall rapidly, and other high-output states such as thyrotoxicosis, anemia, PDA, AVM, and severe fever. Clinically, it is best detected by raising the patient's arm above the head while feeling the radial pulse with the flat of your hand — this accentuates the collapse. It indicates significant AR requiring assessment of severity by echocardiography."

Question 2 (Intermediate): "Your patient has a mid-diastolic murmur. How do you differentiate mitral stenosis from Austin Flint murmur?"

→ Ideal Answer: "Both are mid-diastolic rumbling murmurs at the apex. The differentiating features are:

In MS: loud S1, opening snap present, parasternal heave and signs of right heart involvement from pulmonary hypertension
In Austin Flint: S1 is soft, NO opening snap, and you will find the signs of AR — collapsing pulse, Erb's point early diastolic murmur, displaced hyperdynamic apex
On echo: MS shows thickened calcified mitral valve with doming; Austin Flint shows normal valve with AR jet on Doppler
Austin Flint occurs because the AR jet from the aorta impinges on the anterior mitral leaflet, preventing its full opening, creating a functional stenosis"

Question 3 (Difficult): "How would you manage a patient with severe MS who is in AF and develops acute pulmonary edema?"

→ Ideal Answer: "This is a cardiology emergency. My approach:

Immediate: Sit patient up, high-flow oxygen, IV access, monitoring
Rate control is the PRIORITY — the tachycardia of AF is especially dangerous in MS because it reduces diastolic filling time, dramatically increasing transvalvular gradient and pulmonary pressures. Use IV metoprolol or diltiazem. Digoxin is slower but appropriate.
Diuretics: IV furosemide to reduce preload
Anticoagulation: If new AF, therapeutic anticoagulation (heparin bridge to warfarin, or DOAC — though DOACs are not preferred in MS with AF per current guidelines — warfarin target INR 2-3 or 2.5-3.5 if mitral prosthesis)
Cardioversion: If AF is new (<48 hours), cardioversion after ruling out thrombus or after adequate anticoagulation
Definitive: Balloon mitral valvuloplasty (PTMC) if suitable valve anatomy (Wilkins score ≤8), or surgical MVR if unsuitable
Monitor for deterioration requiring ICU transfer"

Question 4 (Examiner-level): "A 60-year-old man is admitted with sudden-onset severe chest pain radiating to the back, BP 180/100 in right arm and 140/90 in left arm. What is your diagnosis and immediate management?"

→ Ideal Answer: "This presentation is classical for aortic dissection — specifically Type A (involving ascending aorta) until proven otherwise, given the blood pressure differential between arms indicating involvement of a subclavian artery origin. My immediate approach:

Do NOT perform thrombolysis — this is the critical mistake that kills patients when aortic dissection is mistaken for MI
Pain control: IV morphine or fentanyl
Target HR <60 bpm and SBP 100-120 mmHg: IV labetalol (drug of choice — simultaneous beta + alpha blockade reduces aortic wall stress). If pure beta-blocker first, add nitroprusside after — never nitroprusside alone (reflex tachycardia worsens shear stress)
Investigations: CT aortography (gold standard), CXR (widened mediastinum >8 cm, irregular aortic knuckle), bedside echo (AR, tamponade, LV wall motion)
Type A dissection → Emergency surgery (mortality 1-2% per hour without surgery)
Type B dissection (descending only) → Medical management unless complicated (malperfusion, rupture, uncontrolled pain)
Stanford Classification: A = ascending ± descending; B = descending only
Call cardiothoracic surgery IMMEDIATELY for Type A"

TONIGHT'S MISSION — CARDIOLOGY + RESPIRATORY SELF-ASSESSMENT CHECKLIST

Before you sleep tonight, verify you can do ALL of the following without hesitation:

CARDIOLOGY:

Assess JVP correctly, describe waveforms, state clinical meaning
Differentiate collapsing vs plateau vs bisferiens pulse
Describe the COMPLETE cardiac examination sequence
Grade a murmur correctly (Levine scale)
State all Levine criteria for MS severity
Distinguish MS vs AR vs MR vs AS by examination
Perform and interpret dynamic auscultation
Read any of the 10 high-yield ECGs in 60 seconds
Manage acute pulmonary edema and aortic dissection

RESPIRATORY:

Differentiate effusion / consolidation / pneumothorax / collapse / COPD by examination
Use Light's criteria correctly
Interpret an ABG (especially Type I vs Type II RF)
Read a CXR systematically
Manage COPD exacerbation (including target SpO2 88-92%)

DAY 2 PREVIEW: NEUROLOGY + GASTROENTEROLOGY/HEPATOLOGY

Tomorrow we will cover:

Complete neurological examination (cranial nerves, motor, sensory, cerebellar)
UMN vs LMN differentiation (exam favourite)
Coma examination
Cirrhosis/portal hypertension examination
Ascites (shifting dullness, fluid thrill, causes, SBP)
Jaundice (pre-hepatic/hepatic/post-hepatic)
Hepatosplenomegaly examination
Viva: Hepatic encephalopathy management, SBP, Wilson's disease, hepatorenal syndrome

DAY 3 PREVIEW: ENDOCRINE + RHEUMATOLOGY + RENAL + FULL MOCK EXAM

Thyroid examination (toxic goitre, hypothyroidism, solitary nodule)
Diabetes complications examination
Cushing's vs Addison's
Rheumatoid arthritis vs OA vs SLE hands
Chronic kidney disease examination
Full mock practical with marks and feedback

HIGH-YIELD MNEMONICS FOR TODAY

CAUSES OF CLUBBING: CLUBBING

Cancer (bronchogenic, mesothelioma)
Lung abscess, empyema
Ulcers (IBD — Crohn's, UC)
Bronchiectasis, cystic fibrosis
Biliary cirrhosis, liver disease
Infective endocarditis
Not COPD, NOT asthma (very common exam trap!)
Growth (congenital cyanotic heart disease)

CAUSES OF STONY DULL PERCUSSION: "FFF - Fluid, Fibrosis, Fat" — Actually only FLUID gives stony dull (classic teaching). Fibrosis and consolidation give ordinary dullness.

MURMUR RADIATION:

MS → axilla (no, that's MR!)
MR → LEFT AXILLA
AS → CAROTIDS
AR → Erb's point (base of heart)
TR → Right sternal border, increases with inspiration

COMMUNICATION PEARLS — WHEN EXAMINER CORRECTS YOU

Never say: "No, I think I'm right..."

ALWAYS say:

"Thank you, sir/ma'am. Could you please clarify — I may have missed that finding."
"I stand corrected. On reflection, the finding of [X] more likely indicates [Y] because..."
If genuinely uncertain: "Sir, I am not entirely certain about this aspect. Based on my understanding, it could be [X], but I would appreciate your guidance."

This response earns MORE marks than a wrong confident answer.

KEY TAKE-HOME MESSAGES FOR DAY 1

Every examination must follow a system — examiners fail those who skip steps
JVP is the single most-missed finding in cardiac cases — always assess it
Stony dull = pleural effusion — the most specific percussion note in medicine
Never give O2 above 92% in COPD without close monitoring
Type A aortic dissection = surgical emergency — do NOT thrombolyse
HOCM murmur behaves opposite to AS — increases on standing, decreases on squatting
Inferior MI → always check for RV involvement → avoid nitrates
Dynamic auscultation separates good candidates from distinction candidates
Present with confidence — even a wrong diagnosis presented well earns more marks than the right diagnosis presented poorly
Light's criteria — memorize the three conditions, any ONE makes it an exudate

We start Day 2 whenever you are ready. Send me a message saying "Day 2" and we will begin Neurology and GI/Hepatology.

OR — if you want to practice a viva on anything from today, ask me any question and I will examine you exactly as your real examiner will.

Practice a full cardiac long case presentation from start to finish

🏥 FULL CARDIAC LONG CASE — LIVE SIMULATION

I am now your MD Examiner. This is your RGUHS Final Practical Examination.

📋 PATIENT SCENARIO

You walk into the examination hall. The examiner points to Bed 4 and says:

"Dr. [Your Name] — please examine this patient completely and present your findings. You have 45 minutes for history and examination. Then present to me."

THE PATIENT

You approach the bed and see:

A middle-aged woman, approximately 38 years old, sitting propped up on 3 pillows. She appears mildly breathless at rest. She has a pinkish-purple discoloration over both cheeks. She looks thin but not cachectic. An IV line is in-situ in the left arm.

⏱️ YOUR 45-MINUTE CLOCK STARTS NOW

I will play the patient AND the examiner.

Work through this exactly as you would in the real exam:

Enter, introduce, obtain consent
Take a focused history — ask me questions, I will answer as the patient
Describe your examination findings — tell me what you are doing and what you find
Present the case — full consultant-level presentation
I will then viva you

🎭 START HERE

The examiner is watching. Walk up to the bed.

What is the FIRST thing you say and do?

(Type exactly what you would say to the patient and describe your first actions. Be specific — the examiner is watching every move.)

I will respond as the patient with appropriate history, and as the examiner with real-time feedback on your technique, language, and sequence. Every mistake will be corrected immediately.

Go ahead — begin.
