NEET-PG 2024 Practice Questions

Q: The Image shows the growth curve of different organs with age. Identify A in the graph.

Lymphoid Growth. ***Lymphoid Growth*** - Curve 'A' shows a rapid increase in size during **childhood**, peaking around **10-12 years of age**, and then declining to adult levels. - This pattern is characteristic of **lymphoid tissues** (e.g., thymus, lymph nodes, tonsils), which are larger relative to body size in childhood and undergo involution post-puberty. *Brain Growth* - **Neural growth** (like the brain) typically shows very rapid growth in early childhood, reaching close to adult size by about 6-7 years of age, and then leveling off. - Curve 'A' continues to grow rapidly much longer than expected for brain development and then shows a distinct decline. *Somatic Growth* - **General somatic growth** (e.g., body as a whole) shows a sigmoid curve, with rapid growth in infancy and adolescence, and a plateau in adulthood. - Curve 'A' peaks significantly above the 100% mark and then declines, which is not characteristic of overall somatic growth. *Gonadal Growth* - **Genital (gonadal) growth** remains relatively flat until puberty, after which it experiences a rapid increase. - Curve 'A' shows significant growth in early childhood and a peak before puberty, which is inconsistent with typical gonadal development. *Reproductive Growth* - **Reproductive growth** follows the same pattern as gonadal growth, remaining minimal until puberty with subsequent rapid increase. - Curve 'A' demonstrates early childhood growth and pre-pubertal peak, which does not match the reproductive growth pattern.

Q: A patient presents with features of heart failure. On examination, an irregularly irregular pulse is noted, and the patient has a loud diastolic sound. The jugular venous pressure (JVP) shows a rapid Y descent. What is the most likely diagnosis?

Mitral stenosis. ***Mitral stenosis*** - An **irregularly irregular pulse** suggests **atrial fibrillation**, a common complication of mitral stenosis due to left atrial enlargement. - A **loud diastolic sound**, also known as an **opening snap**, is characteristic of a stenotic mitral valve as it opens, occurring early in diastole. - The **rapid Y descent** on JVP can occur due to elevated right-sided pressures from pulmonary hypertension secondary to mitral stenosis. *Constrictive pericarditis* - While it can cause heart failure and an elevated JVP with a rapid Y descent (**Friedreich's sign**), the description of an "irregularly irregular pulse" and a "loud diastolic sound" (opening snap) is not typical. - The loud diastolic sound in constrictive pericarditis would be a **pericardial knock**, which is usually later than an opening snap and less distinct. *Cardiac tamponade* - Characterized by **Beck's triad** (hypotension, muffled heart sounds, elevated JVP) and often presents with **pulsus paradoxus**. - The JVP in tamponade typically shows an **absent or diminished Y descent**, due to impaired ventricular filling from external compression. *Aortic regurgitation* - Causes a **diastolic murmur**, but not a loud diastolic sound or opening snap. - The pulse is often a **collapsing pulse** or **water-hammer pulse**, and it is not typically irregularly irregular unless atrial fibrillation or another arrhythmia is co-existent. *Mitral regurgitation* - Can cause heart failure and atrial fibrillation, but the characteristic finding is a **pansystolic murmur**, not a loud diastolic sound. - There is no opening snap in mitral regurgitation; instead, there may be an **S3 gallop** in severe cases. - The rapid Y descent is less prominent compared to mitral stenosis.

Q: 274. A young athlete was found to have hypertrophic cardiomyopathy during testing for a competitive sport. Which of the following maneuvers will increase the murmur?

Valsalva maneuver. **Valsalva maneuver** - The **Valsalva maneuver** reduces **preload** by decreasing venous return to the heart. - A decrease in preload reduces the left ventricular chamber size, which in turn exacerbates the **left ventricular outflow tract (LVOT) obstruction** characteristic of hypertrophic cardiomyopathy (HCM), thereby **increasing the intensity of the murmur**. *Handgrip* - **Handgrip** is an isometric exercise that leads to an increase in **afterload** and **peripheral vascular resistance**. - Increased afterload causes the left ventricle to eject blood against higher pressure, which **enlarges the left ventricular chamber** and **reduces the LVOT obstruction**, thus **decreasing the intensity of the murmur** in HCM. *Squatting* - **Squatting** increases both **preload** (due to increased venous return) and **afterload** (due to increased peripheral vascular resistance). - The increased preload and afterload lead to an **increased left ventricular volume**, which **reduces the LVOT obstruction** and therefore **decreases the intensity of the murmur** in HCM. *Passive leg raise* - **Passive leg raise** increases **preload** by increasing venous return to the heart from the lower extremities. - The increased preload leads to an **increased left ventricular chamber size**, which **reduces the LVOT obstruction** and therefore **decreases the intensity of the murmur** in HCM. *Leaning forward* - Leaning forward during auscultation is typically used to better hear **aortic regurgitation murmurs**, as it brings the aorta closer to the chest wall. - This maneuver does not significantly alter **cardiac preload or afterload** in a way that would consistently increase the murmur of hypertrophic cardiomyopathy.

Q: Match the following A. Atrial fibrillation B. Atrial flutter C. PSVT D. Ventricular tachycardia

A-2, B-1, C-3, D-4. ***A-2, B-1, C-3, D-4*** - Image 2 shows irregularly irregular QRS complexes with no discernible P waves, which is characteristic of **atrial fibrillation**. - Image 1 shows a "sawtooth" pattern of atrial activity, indicative of **atrial flutter**. - Image 3 displays a narrow complex tachycardia with a very regular rhythm, consistent with **PSVT**. - Image 4 demonstrates wide, regular QRS complexes without clear P waves, which is the hallmark of **ventricular tachycardia**. *A-1, B-2, C-3, D-4* - This option incorrectly matches atrial fibrillation with the "sawtooth" pattern (image 1) and atrial flutter with the irregularly irregular rhythm (image 2). - Atrial fibrillation is characterized by the absence of discrete P waves and irregular ventricular response (image 2), while atrial flutter shows organized atrial activity with a "sawtooth" pattern (image 1). *A-1, B-2, C-4, D-3* - This option misidentifies image 1 as atrial fibrillation and image 2 as atrial flutter, which are reversed. - It also incorrectly matches PSVT with image 4 (ventricular tachycardia) and ventricular tachycardia with image 3 (PSVT). *A-2, B-1, C-4, D-3* - This option correctly identifies atrial fibrillation (A-2) and atrial flutter (B-1), but incorrectly swaps the ventricular and supraventricular tachycardias. - Image 3 shows narrow complex tachycardia (PSVT), not the wide complex pattern of ventricular tachycardia seen in image 4. *A-4, B-3, C-2, D-1* - This option incorrectly matches all the rhythms to the wrong images, demonstrating a fundamental misunderstanding of their characteristic ECG features. - For example, it matches atrial fibrillation to image 4 (ventricular tachycardia) and ventricular tachycardia to image 1 (atrial flutter).

Q: A 45-year-old male presents to the emergency department following a motor vehicle accident. He complains of severe chest pain and difficulty breathing. On examination, he appears distressed, with a respiratory rate of 28 breaths per minute. His oxygen saturation is 88% on room air. There is visible bruising on the chest, X-ray is done which is shown below. Which of the following is seen in this patient?

Bronchial breathing. ***Bronchial breathing*** - The provided image is a chest X-ray. The question describes a patient with severe chest pain, difficulty breathing, hypoxemia, and visible chest bruising after a motor vehicle accident, which suggests **pulmonary contusion** or **pneumonia**. - In such conditions, **bronchial breathing** might be heard on auscultation due to consolidation or compression of lung tissue. The X-ray shows diffuse infiltrates or opacities indicative of lung injury, making bronchial breathing a plausible physical exam finding. *Kussmaul breathing* - This is a pattern of **deep and labored breathing** associated with severe **metabolic acidosis**, particularly diabetic ketoacidosis. - While the patient is in distress, the chest X-ray and accident history point to acute respiratory injury rather than metabolic acidosis as the primary cause. *Paradisical breathing* - This term is **not a recognized medical breathing pattern**. It appears to be a distracter. - Medical terminology for breathing patterns includes terms like Kussmaul, Cheyne-Stokes, Biot's, etc. *Apneustic breathing* - Characterized by **prolonged inspiratory pauses** followed by short exhalations, indicating severe damage to the **pons (brainstem)**. - This breathing pattern is typically seen with neurological insults like stroke or severe head injury, which is not directly indicated by the information given, although a head injury could theoretically occur in a MVC, it's not the primary finding for the presented complaints and X-ray.

Q: Identify the maneuver shown in the image:

Mauriceau-Smellie-Veit. ***Mauriceau-Smellie-Veit*** - This maneuver is used for **head delivery in a breech presentation**, where the fetus's body is supported while pressure is applied to the maxilla or mandible to flex the head. - The image typically shows the operator's hand supporting the fetus's body and fingers placed on the fetal jaw to facilitate head flexion and delivery. *Burn Marshall* - The Burn Marshall maneuver involves **delivering the fetal head by applying suprapubic pressure** to the maternal abdomen while the fetal body is gently swept upwards over the maternal abdomen. - This maneuver is generally used for a **spontaneous breech delivery** if the head does not deliver easily after the body. *Lovset* - The Lovset maneuver is employed to **deliver the fetal shoulders** in a breech presentation by rotating the fetal trunk to bring the anterior shoulder under the pubic arch and then the posterior shoulder. - This maneuver aims to extract the shoulders sequentially, which might be necessary if they are impacted. *None of the options* - The visual representation aligns with the steps of the Mauriceau-Smellie-Veit maneuver, making this option incorrect. - This maneuver is clearly depicted by the hand placement and objective of aiding head delivery in breech.

Q: A patient presents with an umbilical mass, which was previously reducible but has now become irreducible with discharge coming out, as shown in the image. What is the most appropriate management?

Umbilical excision with mesh hernioplasty. ***Umbilical excision with mesh hernioplasty*** - The presence of an **irreducible umbilical mass with discharge** indicates a complicated umbilical hernia, likely with **incarceration, strangulation, or infection**. - Management requires **excision of compromised tissue** (umbilicus and surrounding necrotic/infected skin) followed by **hernia defect repair**. - **Mesh hernioplasty** provides strong, durable reinforcement and prevents recurrence. - **Note:** In heavily contaminated fields, primary tissue repair or biologic mesh may be preferred over synthetic mesh, or staged repair may be considered. However, if contamination is minimal after debridement, mesh repair can be performed in the same setting. *Umbilical excision* - While **excision of the compromised umbilical skin and necrotic tissue** is necessary due to the discharge (suggesting infection or necrosis), **excision alone does not address the underlying hernia defect**. - Simply excising the umbilicus without repairing the hernia would lead to **persistent hernia or recurrence**. *Mesh hernioplasty* - A mesh hernioplasty alone is appropriate for **uncomplicated, reducible umbilical hernias** to reinforce the abdominal wall. - However, it **does not account for the irreducibility and skin changes/discharge**, which necessitate **excision of potentially infected or necrotic tissue** first. - Placing mesh without addressing the compromised tissue would risk ongoing infection and mesh complications. *Conservative* - **Conservative management** is reserved for **asymptomatic, reducible umbilical hernias** in adults (especially if small) or for infants where spontaneous closure can occur. - An **irreducible mass with discharge** signifies an **acute surgical emergency** (incarceration, strangulation, or infection) requiring **urgent surgical intervention**, not observation.

Q: What type of ulcer is shown below?

Arterial ulcer. ***Arterial ulcer*** - The image depicts an ulcer with a **punched-out appearance**, often found on the toes, heels, or shin, indicative of **arterial insufficiency**. - The surrounding skin appears **pale** and might show signs of **trophic changes** (e.g., hair loss, shiny skin), consistent with poor arterial blood supply. *Venous ulcer* - Venous ulcers typically occur around the **medial malleolus**, are superficial, and have irregular borders with a **"gaiter" appearance** (brawny edema and hyperpigmentation). - The ulcer bed is usually ruddy red with **exudate** and the surrounding skin often shows signs of **venous stasis changes**. *Trophic ulcer* - "Trophic ulcer" is a broad term for an ulcer caused by **poor nutrition** or nerve supply, and can encompass arterial or neuropathic ulcers. - This term is less specific than identifying the underlying vascular etiology shown in the image. *Diabetic foot* - Diabetic foot ulcers often occur on **pressure points** of the foot, such as the plantar surface or the heel, and can be neuropathic or neuro-ischemic. - While this image could potentially be associated with diabetes due to microvascular complications, the **punched-out, ischemic appearance** more strongly points to an arterial origin which can occur independently of diabetes.
