Question 501: Which of the following substances, at the given concentration, makes water unsuitable for human consumption according to safety standards?
- A. Cadmium – 0.3 mg/L (Correct Answer)
- B. Calcium – 7 mg/L
- C. Chloride – 200 mg/L
- D. Fluoride – 0.8 mg/L
Explanation: ***Cadmium – 0.3 mg/L*** - The maximum permissible limit for **Cadmium** in drinking water is extremely low, typically around **0.003 mg/L** (WHO standard), due to its high toxicity. - A concentration of 0.3 mg/L is 100 times the safe limit and poses severe health risks, particularly **kidney damage**. *Fluoride – 0.8 mg/L* - The optimal acceptable range for **Fluoride** is generally between **0.6 and 1.5 mg/L**, a concentration that helps prevent dental caries. - A concentration of 0.8 mg/L is well within the acceptable limit and is often considered optimal for public health. *Chloride – 200 mg/L* - The acceptable limit for **Chloride** is usually **250 mg/L** (or up to 1000 mg/L as the maximum permissible limit), with higher levels primarily affecting taste and causing corrosion. - 200 mg/L is below the acceptable range and does not render the water unsuitable for drinking. *Calcium – 7 mg/L* - **Calcium** is an essential mineral, and its typical acceptable limit for drinking water is much higher, often around **75 mg/L** (or related to overall water hardness). - This concentration is extremely low and poses no health risk; it is perfectly safe for consumption.

Question 501: A man was abducted from his home, and his son subsequently claimed rights to his father’s property. As per Section 111 of the Bharatiya Sakshya Adhiniyam (BSA), until when is the son not entitled to claim inheritance?
- A. 10 years
- B. 5 years
- C. 7 years (Correct Answer)
- D. 6 years
Explanation: ***7 years*** - Section 111 of the **Bharatiya Sakshya Adhiniyam (BSA)** (previously Sec 108 of the Indian Evidence Act) establishes the presumption of death after a person has not been heard of for **seven years**. - Inheritance claims based on the father's presumed death cannot be entertained until this mandated **seven-year period** has elapsed, as the person is legally presumed alive until then. *5 years* - This period is insufficient under the BSA to raise a legal **presumption of death** necessary for transferring property rights. - The minimum statutory period required for shifting the burden of proof regarding the existence of the missing person is longer than **five years**. *6 years* - Although close, **six years** does not meet the legal threshold established by **Section 111 of the BSA** for the presumption of death. - The burden of proof remains on the party asserting the death until the full **seven-year period** is completed. *10 years* - This duration exceeds the statutory period required; the courts can legally presume death and allow inheritance claims after the mandatory **seven years**. - Waiting **10 years** is unnecessary, as the right to claim inheritance based on presumed death arises immediately after the completion of the **seven-year requirement**.

Question 501: A 39-year-old male with symptoms of stress and work-life imbalance is diagnosed with Stage 2 hypertension (blood pressure 150/95 mmHg on three separate occasions) and impaired fasting glucose (120 mg/dL). What is the most appropriate pharmacological management?
- A. Start thiazide diuretic
- B. Advise rest only, no pharmacological treatment
- C. Start glucocorticoids
- D. Start telmisartan (Correct Answer)
Explanation: Start telmisartan - **Telmisartan** is an Angiotensin II Receptor Blocker (ARB), the most appropriate first-line choice for treating **Stage 2 hypertension** (150/95 mmHg) in patients with metabolic risk factors like **impaired fasting glucose**. [1] - ARBs are **metabolically neutral or beneficial**, providing cardiovascular protection and reducing progression to diabetes in patients with prediabetes. [1] - They offer **renal protection** (nephropathy prevention), which is crucial in patients at risk for developing diabetes mellitus. [1] - ARBs and ACE inhibitors are preferred over other antihypertensives in patients with metabolic syndrome. [1] *Start glucocorticoids* - Glucocorticoids are **absolutely contraindicated** in hypertension management and would severely worsen both conditions. - They cause **iatrogenic hypertension** and **hyperglycemia**, potentially precipitating diabetes mellitus. - This option represents a dangerous treatment choice with no role in this clinical scenario. *Start thiazide diuretic* - While thiazide diuretics are effective antihypertensives and commonly used first-line agents, they have **adverse metabolic effects**. [1] - Thiazides can worsen **glucose tolerance** and precipitate diabetes in prediabetic patients. [1] - They may also cause **dyslipidemia** and worsen metabolic syndrome components. - In patients with impaired fasting glucose, ARBs/ACE inhibitors are preferred due to their superior metabolic profile. [1] *Advise rest only, no pharmacological treatment* - **Stage 2 hypertension** (≥140/90 mmHg) with confirmed multiple elevated readings requires **immediate pharmacological therapy** alongside lifestyle modifications. - While addressing stress and work-life balance through lifestyle changes is important, these measures alone are insufficient for Stage 2 hypertension. - Delaying treatment increases cardiovascular risk, including stroke, myocardial infarction, and heart failure. [1] - Current guidelines (ACC/AHA, ESC/ESH) mandate pharmacological intervention for Stage 2 hypertension at initial diagnosis. [1]
Question 502: A patient with chronic kidney disease presents with severe anemia. Laboratory tests reveal normocytic, normochromic anemia. What is the most appropriate treatment to manage this patient's anemia?
- A. Vitamin B12 injection
- B. Folic acid supplementation
- C. Darbepoetin alfa (Correct Answer)
- D. Iron chelation therapy
Explanation: ***Darbepoetin alfa*** - Anemia in **Chronic Kidney Disease (CKD)** is predominantly caused by decreased production of **erythropoietin** by the failing kidneys, resulting in normocytic, normochromic anemia [1] - **Darbepoetin alfa** is a long-acting **Erythropoiesis-Stimulating Agent (ESA)** that replaces the deficient hormone, directly correcting the underlying cause of anemia in CKD - This is the **standard of care** for managing anemia in CKD patients with normocytic, normochromic presentation *Folic acid supplementation* - Indicated for **megaloblastic anemia** due to **folate deficiency**, which presents as macrocytic anemia (high MCV) [2] - Does not stimulate red blood cell production directly and is ineffective against the primary defect of **erythropoietin deficiency** in CKD - The patient's normocytic anemia excludes folate deficiency [2] *Vitamin B12 injection* - Standard treatment for Vitamin B12 deficiency (e.g., **pernicious anemia**), which causes macrocytic, megaloblastic anemia [2] - The patient presents with **normocytic** anemia, indicating the deficiency is not related to B12 or folate metabolism - No indication for B12 supplementation in this clinical scenario *Iron chelation therapy* - **Iron chelation** is used to treat severe **iron overload** (hemochromatosis) or toxicity, not to treat anemia - Patients with CKD-related anemia often require supplemental **iron** to enhance their response to ESAs like Darbepoetin alfa - Using chelation would be counterproductive and worsen the anemia

2 questionsBernard-Soulier syndrome is caused by a defect in which of the following platelet glycoproteins?
A patient with renal disease undergoes a biopsy. On Congo red staining, the deposits show apple-green birefringence under polarised light. What is the most likely diagnosis?
FMGE 2025 - Pathology FMGE Practice Questions and MCQs
Question 501: Bernard-Soulier syndrome is caused by a defect in which of the following platelet glycoproteins?
- A. GpIb/IX complex (Correct Answer)
- B. GpIV
- C. GpIa/IIa
- D. GpIIb/IIIa
Explanation: ***GpIb/IX complex***- Bernard-Soulier syndrome (BSS) is a rare, autosomal recessive bleeding disorder caused by a quantitative or qualitative defect in the **platelet GpIb/IX/V complex** [1].- This complex acts as the essential high-affinity receptor for **von Willebrand factor (vWF)**, mediating initial **platelet adhesion** to the injured vessel wall, which is impaired in BSS [1], [2].*GpIIb/IIIa*- A defect in **GpIIb/IIIa** (integrin $\alpha_{IIb}\beta_3$) causes **Glanzmann thrombasthenia**, which presents with impaired **platelet aggregation**, not adhesion [1].- GpIIb/IIIa is the receptor for **fibrinogen**, which is necessary to link aggregating platelets [1], [2].*GpIa/IIa*- **GpIa/IIa** (integrin $\alpha_2\beta_1$) is primarily a receptor for **collagen** on the platelet surface, mediating adhesion in parallel with GpIb/vWF.- While important for hemostasis, defects in this receptor generally cause only mild bleeding and not the characteristic **giant platelets** or severe adhesion defect seen in BSS.*GpIV*- **GpIV** (also known as CD36) is a scavenger receptor that binds to **thrombospondin** and sometimes collagen.- Platelet defects related to GpIV are rare and usually involve mild aggregation defects, distinct from the severe adhesion failure defined by BSS. **References:** [1] Kumar V, Abbas AK, et al..

Question 502: A patient with renal disease undergoes a biopsy. On Congo red staining, the deposits show apple-green birefringence under polarised light. What is the most likely diagnosis?
- A. Diabetic nephropathy
- B. Amyloidosis (Correct Answer)
- C. Membranous nephropathy
- D. Minimal change disease
Explanation: ***Amyloidosis***- This feature is the **pathognomonic microscopic manifestation** of amyloid deposition, where the Congo red stain binds specifically to the parallel **cross-beta sheet** configuration of amyloid fibrils [1].- When viewed under **polarized light**, this interaction results in the classic **apple-green birefringence** due to the ordering of the deposited protein [1], [2]. *Minimal change disease*- The diagnosis of minimal change disease relies primarily on **electron microscopy**, which shows **effacement of podocyte foot processes**.- On **light microscopy**, the glomeruli appear virtually normal, and there are no deposits present that would stain positively with Congo red. *Diabetic nephropathy*- Characteristic findings on light microscopy include **diffuse mesangial expansion** and the formation of **Kimmelstiel-Wilson nodules** (nodular glomerulosclerosis).- The thickening of the glomerular basement membrane and mesangial expansion are due to hyperglycemia and associated metabolic changes, not amyloid deposition. *Membranous nephropathy*- This nephropathy is defined by the presence of **subepithelial immune complex deposits** that result in a uniformly thickened glomerular basement membrane (GBM).- Silver stains often reveal a classic **"spike and dome"** pattern on the GBM, which is distinct from amyloid fibrils. **References:** [1] Kumar V, Abbas AK, et al..

FMGE 2025 - Pediatrics FMGE Practice Questions and MCQs
Question 501: A child presents with abdominal distension and an enlarged liver by 8cm below the costal margin. The liver is smooth on palpation. Which of the following is the most likely diagnosis?
- A. Glycogen Storage Disease (GSD) (Correct Answer)
- B. Autoimmune Hepatitis
- C. Hepatocellular Carcinoma (HCC)
- D. Lysosomal Storage Disease (LSD)
Explanation: ***Glycogen Storage Disease (GSD)***- GSDs, particularly Type I (**Von Gierke Disease**), cause massive, **smooth hepatomegaly** due to the accumulation of normal or abnormal glycogen within hepatocytes.- The presentation in childhood with severe abdominal distension and an enlarged, non-tender, **smooth liver** is highly characteristic of these metabolic disorders.*Lysosomal Storage Disease (LSD)*- While LSDs (e.g., Gaucher, Niemann-Pick) can cause hepatomegaly, they often involve the **Reticuloendothelial system**, leading to prominent **splenomegaly** as well, which is not mentioned here.- Clinical features usually include severe **neurological impairment** or **skeletal abnormalities**, differentiating them from GSDs which primarily affect the liver and glucose metabolism initially.*Hepatocellular Carcinoma (HCC)*- HCC usually results in a **firm, nodular, or irregular** liver surface on palpation, reflecting tumor growth, rather than a uniformly smooth enlargement.- Although rare in children, when it occurs, it is typically associated with rapidly worsening symptoms, weight loss, and often underlying conditions like **cirrhosis** or **hepatitis**.*Autoimmune Hepatitis*- This condition involves chronic **inflammation and destruction of hepatocytes**, often leading to symptoms of liver failure (jaundice) and elevated **transaminases**.- Long-standing autoimmune hepatitis progresses to cirrhosis, resulting in a **fibrotic or nodular** liver, rarely presenting as primary, massive, smooth hepatomegaly in a child.

Question 501: A 12-year-old child presents with palpitations, tremors, dry mouth, heart rate 130 bpm, respiratory rate 34/min. Which of the following substances is most likely responsible?
- A. TCA (tricyclic antidepressant) (Correct Answer)
- B. Opioid
- C. Propranolol
- D. Lithium
Explanation: ***TCA (tricyclic antidepressant)***- The constellation of tachycardia (palpitations, HR 130 bpm), tremors, and dry mouth suggests a severe mixed toxidrome, highly characteristic of a TCA overdose.- TCAs exhibit potent **anticholinergic effects** (dry mouth, tachycardia) combined with severe **sodium channel blockade** (contributing to CNS symptoms like tremors and cardiovascular instability) resulting in this critical presentation [1].*Lithium*- Lithium toxicity primarily presents with progressive **neurological symptoms** like ataxia, coarse tremors, lethargy, and seizures.- While tremor is present, the severe **tachycardia** and pronounced **dry mouth** are not typical primary features of the lithium toxidrome.*Opioid*- Opioid toxicity is defined by the classic triad of **miosis** (pinpoint pupils), **respiratory depression** (bradypnea), and altered consciousness.- The patient is profoundly **tachycardic** (130 bpm) and **tachypneic** (34/min), which directly contradicts the expected findings of an opioid overdose.*Propranolol*- Propranolol is a **beta-blocker**, and its overdose typically causes **bradycardia**, hypotension, and potential non-cardiogenic pulmonary edema.- The patient's presentation of significant **tachycardia** (130 bpm) rules out poisoning by a beta-blocking agent.
Question 502: A 75 kg person is administered a drug with a half-life of 3 hours. What is the approximate clearance of the drug?
- A. 6770 mL/min
- B. 1670 mL/min
- C. 23 mL/min (Correct Answer)
- D. 210 mL/min
Explanation: ⚠️ **Note:** This question cannot be solved using standard pharmacokinetic formulas without the volume of distribution (Vd). The answer relies on estimation principles rather than exact calculation. ***23 mL/min*** - This represents a **low to moderate clearance** value, typical for drugs that undergo hepatic metabolism with low-to-intermediate extraction ratios - For context: Normal **creatinine clearance** (marker of GFR) is approximately 90-120 mL/min in adults [1], so 23 mL/min represents roughly 20-25% of renal clearance capacity - This is a plausible value for drugs with **predominantly hepatic metabolism** with low hepatic extraction ratio - Using the relationship $Cl = \frac{0.693 \times Vd}{t_{1/2}}$, this would correspond to a Vd of approximately 6 liters (if t½ = 3 hours) [2] *210 mL/min* - This represents **moderate to high clearance**, suggesting efficient elimination - Comparable to **renal plasma flow** (approximately 600-700 mL/min × filtration fraction) - Would require a Vd of approximately 54 liters with the given half-life - Typical for drugs with good renal excretion or intermediate hepatic extraction *1670 mL/min* - This is extremely high clearance, approaching **total hepatic blood flow** (1500 mL/min) - Would require Vd of approximately 433 liters, which exceeds total body water (42L in a 70kg person) - Only seen with high extraction ratio drugs (>0.7) with extensive first-pass metabolism - Physiologically implausible for most drugs *6770 mL/min* - This clearance is **physiologically impossible** as it exceeds cardiac output (5-6 L/min = 5000-6000 mL/min) [3] - Clearance cannot exceed the blood flow to the eliminating organ [3] - Clearly a distracter option with no pharmacokinetic validity
Question 503: Which medication can be administered to reduce the frequency of future headache episodes in a 26-year-old female patient who experiences one-sided pulsating headaches accompanied by nausea, vomiting, and sensitivity to light and finds relief in a dimly lit environment?
- A. Diazepam
- B. Propranolol (Correct Answer)
- C. Fluoxetine
- D. Alprazolam
Explanation: ***Propranolol***- This is a non-selective **beta-blocker** and is considered a first-line prophylactic agent for the reduction of frequency and severity in patients with **episodic migraine** [1].- The patient's symptoms (unilateral, pulsating headache, **nausea, vomiting, and photophobia**) [2] are classic features of migraine, making **Propranolol** an appropriate choice for maintenance therapy [3].*Alprazolam*- This medication is a **short-acting benzodiazepine** primarily indicated for the acute management of anxiety and panic disorders [3].- It has **no established role** in the long-term prophylactic management of migraine and carries risks of sedation and dependence.*Diazepam*- This is a **long-acting benzodiazepine** commonly used as a muscle relaxant, anxiolytic, and for acute seizure management.- Similar to Alprazolam, it is **not recommended** for headache prophylaxis due to lack of efficacy and significant abuse potential [3].*Fluoxetine*- This drug is a selective serotonin reuptake inhibitor (**SSRI**) primarily used to treat **major depressive disorder** and anxiety [3].- While some antidepressants (like TCAs) are used for migraine prophylaxis, **Fluoxetine** is generally not considered a standard or preferred first-line agent for preventing migraine attacks.
