Question 1: At what altitude is kala azar unlikely to occur?
- A. 400 meters
- B. 500 meters
- C. 600 meters (Correct Answer)
- D. 200 meters
Explanation: ***600 meters*** - Kala-azar, or **visceral leishmaniasis**, is primarily found in **low-lying areas** and is rarely reported at altitudes above 600 meters due to the specific ecological requirements of its **sand fly vector**. - The **Phlebotomus argentipes sand fly**, the main vector in the Indian subcontinent, prefers warm, humid climates and **lower altitudes**. *400 meters* - This altitude is within the **typical endemic range** for kala-azar, especially in regions like the Indian subcontinent. - The environmental conditions at 400 meters are generally conducive for the **survival and breeding** of the sand fly vector. *500 meters* - Similar to 400 meters, 500 meters is still considered within the **favorable altitude range** for kala-azar transmission. - The **sand fly vector** can thrive in the climate often found at this elevation. *200 meters* - This altitude represents a **highly endemic zone** for kala-azar, as it provides optimal conditions for the sand fly vector. - Lower altitudes are typically associated with increased **humidity and warmth**, favoring vector density and parasite transmission.
Forensic Medicine
1 questionsWhat type of poisoning is associated with the retention of lead bullets in the body?
FMGE 2019 - Forensic Medicine FMGE Practice Questions and MCQs
Question 1: What type of poisoning is associated with the retention of lead bullets in the body?
- A. Lead (Correct Answer)
- B. Phosphorus
- C. Nitro cellulose
- D. Iron
Explanation: ***Lead*** - **Lead bullets** are primarily composed of lead, and if retained in the body, lead can leach into the bloodstream causing **lead poisoning**. - This is a well-documented risk, especially when bullets are lodged in areas rich in bodily fluids or bone. *Phosphorus* - Phosphorus poisoning is typically associated with exposure to compounds like **white phosphorus**, often found in fireworks or industrial chemicals, not lead bullets. - Symptoms include severe gastrointestinal distress, multiorgan failure, and a characteristic **garlic-like odor**. *Nitro cellulose* - **Nitrocellulose** is a component of gun propellants (gunpowder), not the bullet itself. - Exposure would primarily be from inhalation of fumes during firing or accidental ingestion of powder, not retention of the bullet. *Iron* - **Iron poisoning** usually results from acute overdose of iron supplements, particularly in children. - While bullets contain trace amounts of iron, the primary toxic component of a retained bullet is **lead**, not iron.
Internal Medicine
2 questionsWhich of these conditions is classified as a nephritic syndrome?
A 20-year-old male presented with fatigue, weakness, and jaundice. What is the most likely diagnosis?
FMGE 2019 - Internal Medicine FMGE Practice Questions and MCQs
Question 1: Which of these conditions is classified as a nephritic syndrome?
- A. Minimal Change Disease
- B. Membranous Glomerulopathy
- C. Post Infectious Glomerulonephritis (Correct Answer)
- D. Focal Segmental Glomerulosclerosis
Explanation: ***Post infectious Glomerulonephritis*** - Characterized by **hematuria, hypertension, and edema**, typically following an infection, such as streptococcal pharyngitis [2]. - Immune-mediated response leads to **decreased GFR** and signs of nephritic syndrome [1][2]. *Focal segmental glomerulosclerosis* - Primarily causes **nephrotic syndrome**, characterized by proteinuria and edema rather than hematuria [2]. - Often associated with **secondary causes** like obesity or HIV, not typically post-infectious. *Membranous Glomerulopathy* - Results in significant **proteinuria** and is classified as a **nephrotic syndrome** rather than a nephritic one [2][3]. - It presents with **edema and hypoalbuminemia**, lacking the hallmark features of hematuria. *Minimal change disease* - Predominantly causes **nephrotic syndrome** with heavy proteinuria and little to no hematuria [2]. - Young children are commonly affected, and it responds well to **corticosteroid therapy** [1].
Question 2: A 20-year-old male presented with fatigue, weakness, and jaundice. What is the most likely diagnosis?
- A. Acute lymphoblastic leukemia
- B. Chronic myeloid leukemia
- C. Chronic lymphocytic leukemia
- D. Acute myeloid leukemia (Correct Answer)
Explanation: ***Acute myeloid leukemia*** - Presents with **fatigue** and **weakness** due to bone marrow infiltration and resultant cytopenias, typical in this age group [1]. - Often shows **myeloblasts** on peripheral blood smear, confirming the diagnosis [2]. *Chronic myeloid leukemia* - Usually occurs in **older adults** and characterized by **elevated white blood cell counts** with a predominance of mature neutrophils. - Symptoms like fatigue may arise, but there are distinct **Philadelphia chromosome** findings and typically a **longer symptom duration**. *Acute lymphoblastic leukemia* - More common in **younger children** and often associated with **lymphadenopathy** and **thrombocytopenia**, rather than fatigue alone. - Characteristically shows **lymphoblasts** in the blood, which are not mentioned in this patient's presentation. *Chronic lymphocytic leukemia* - Typically presents in adults over **50 years** and is characterized by **lymphocytosis** and often asymptomatic in early stages. - Fatigue may occur but lacks the acute presentation and findings seen in **acute leukemias**. **References:** [1] Cross SS.

FMGE 2019 - Microbiology FMGE Practice Questions and MCQs
Question 1: A bacterium that can thrive at temperatures around 60-70 degrees Celsius is classified as
- A. Thermophilic (Correct Answer)
- B. Mesophilic
- C. Cryophilic
- D. Halophilic
Explanation: ***Thermophilic*** - **Thermophilic** bacteria are heat-loving organisms that thrive at high temperatures, typically in the range of **45°C to 80°C**, with optimal growth around 50-70°C - These organisms are commonly found in hot springs, compost heaps, and industrial processes - **Note**: Extreme thermophiles (hyperthermophiles) can grow at temperatures exceeding 80-100°C, found in hydrothermal vents and geothermal environments *Mesophilic* - **Mesophilic** bacteria grow best at moderate temperatures, typically between **20°C and 45°C** - This includes most human pathogens and bacteria found in normal body temperature environments - These organisms cannot survive the high temperatures characteristic of thermophiles *Cryophilic* - **Cryophilic** (or psychrophilic) bacteria are cold-loving organisms that thrive at low temperatures, typically **below 20°C** - These organisms are adapted to cold environments like polar regions, deep oceans, and refrigerated foods - They would be rapidly killed at thermophilic temperature ranges *Halophilic* - **Halophilic** bacteria require high concentrations of salt (NaCl) for growth - This classification is based on **salt tolerance**, not temperature preference - Halophiles can be mesophilic, thermophilic, or psychrophilic depending on their temperature requirements

FMGE 2019 - Obstetrics and Gynecology FMGE Practice Questions and MCQs
Question 1: A 32-year-old pregnant woman presents with mild bleeding and pain. On examination, the uterus is tender, and fetal heart sounds are absent. What is the most likely diagnosis?
- A. Abruptio placenta (Correct Answer)
- B. Uterine rupture
- C. Ectopic pregnancy
- D. Placenta previa
Explanation: ***Abruptio placenta*** - This condition involves the **premature detachment of the placenta** from the uterine wall, leading to bleeding and severe abdominal pain due to uterine contractions and irritation. - The **tender uterus** is a characteristic finding, often described as a "woody hard" uterus in severe cases. - The absence of fetal heart sounds suggests **fetal demise**, which is a common and severe complication of placental abruption due to oxygen deprivation. *Uterine rupture* - **Uterine rupture** can present with abdominal pain, vaginal bleeding, and loss of fetal heart tones, making it an important differential. - However, it typically occurs during **active labor**, especially in women with previous cesarean sections or uterine surgery. - The presentation usually includes **sudden severe pain**, loss of uterine contractions, and the fetus may be palpable abdominally if completely extruded. *Ectopic pregnancy* - This occurs when the **fertilized egg implants outside the uterus**, most commonly in the fallopian tube. - Symptoms typically appear much earlier in pregnancy **(first trimester)** and the pain is usually localized, often presenting with a smaller, non-tender uterus. - Not consistent with the clinical picture of an obviously pregnant uterus. *Placenta previa* - **Placenta previa** is characterized by the placenta covering the cervical opening, leading to **painless vaginal bleeding**, often bright red. - The uterus is typically **soft and non-tender**, in contrast to the tender uterus described in the case. - This is the key differentiating feature from placental abruption.
Question 2: What is the dose of mifepristone in medical abortion?
- A. 400 mg
- B. 100 mg
- C. 200 mg (Correct Answer)
- D. 600 mg
Explanation: ***200 mg*** - The standard dose of **mifepristone** for **medical abortion** in various protocols, including those up to 10 weeks of gestation, is **200 mg orally**. - This dose effectively blocks **progesterone receptors**, leading to endometrial breakdown and sensitization of the uterus to prostaglandins. - **WHO-recommended dose** with optimal efficacy and safety profile. *400 mg* - **400 mg is not a standard or recommended dose** for medical abortion in any established protocol. - The evidence-based regimens use either **200 mg** (current standard) or 600 mg (older protocol), but not 400 mg. - No clinical advantage has been demonstrated for this intermediate dose. *100 mg* - A dose of **100 mg of mifepristone is considered suboptimal** and less effective for inducing medical abortion compared to the standard 200 mg dose. - It may not sufficiently block progesterone receptors, potentially leading to **incomplete abortion** or treatment failure. - Not recommended in any standard medical abortion protocol. *600 mg* - Although **600 mg was an older protocol** for medical abortion, it has largely been replaced by the **200 mg dose**. - Research has demonstrated that **200 mg is equally effective** while resulting in a better side effect profile and lower cost. - The dose reduction from 600 mg to 200 mg represents evidence-based protocol optimization.
Ophthalmology
1 questionsA person with a visual acuity of 6/60 in the right eye and 3/60 in the left eye would be categorized into which type of blindness?
FMGE 2019 - Ophthalmology FMGE Practice Questions and MCQs
Question 1: A person with a visual acuity of 6/60 in the right eye and 3/60 in the left eye would be categorized into which type of blindness?
- A. Moderate visual impairment (Correct Answer)
- B. Legal blindness
- C. Normal vision
- D. Low vision
Explanation: ***Moderate visual impairment*** - According to the **WHO International Classification of Diseases (ICD-11)**, moderate visual impairment is defined as visual acuity **< 6/18 to ≥ 6/60** in the better eye with best possible correction. - This patient's better eye (right eye) has a visual acuity of **6/60**, which falls at the **upper limit** of the moderate visual impairment category. - This is the standard classification used in Indian medical examinations and follows WHO guidelines. *Legal blindness* - **Legal blindness** is a **US administrative/legal term**, not a WHO classification category. It is defined as visual acuity **< 6/60 (or 20/200)** in the better eye, or visual field < 20 degrees. - Since this patient has exactly **6/60** (not less than 6/60), they do **not** meet the strict criteria for legal blindness. - This term is less commonly used in Indian medical literature, where WHO classifications are standard. *Low vision* - **Low vision** is a broad umbrella term that includes all categories of visual impairment from mild to severe, but it is not a specific classification category. - While this patient does have low vision, the more specific and appropriate classification is moderate visual impairment. *Normal vision* - **Normal vision** is defined as visual acuity of **6/6 to 6/12** in the better eye. - This patient's visual acuity of **6/60** represents significant visual impairment, far below the normal range.
Pathology
1 questionsWhich type of necrosis is seen in the brain?
FMGE 2019 - Pathology FMGE Practice Questions and MCQs
Question 1: Which type of necrosis is seen in the brain?
- A. Coagulative
- B. Liquefactive (Correct Answer)
- C. Fat
- D. Fibrinoid
Explanation: ***Liquefactive*** - Liquefactive necrosis is characterized by the transformation of tissue into a **liquid viscous mass**, commonly seen in the brain after **ischemic injury**. - Often associated with brain **infarcts** or **abscess formation**, where cell death results in the accumulation of **neutrophils and pus**. [1] *Fibrinoid* - Fibrinoid necrosis is typically associated with **immune-mediated vascular damage**, not commonly seen in the brain. - This type of necrosis occurs in conditions like **polyarteritis nodosa** or **lupus**, where **fibrin-like protein** deposits are found in vessel walls. *Coagulative* - Coagulative necrosis usually occurs in **myocardial infarction** and is characterized by the preservation of cell outlines due to **denaturation of proteins**. - It is not typical in brain tissue, which undergoes liquefactive necrosis in cases of cell death. *Fat* - Fat necrosis is primarily associated with **enzymatic destruction of adipose tissue**, often related to pancreatic damage or trauma. - It is not relevant to brain necrosis, which does not characteristically present with fat necrosis. **References:** [1] Kumar V, Abbas AK, et al..

Surgery
1 questionsWhich finding is assigned 2 points in the Alvarado scoring system for appendicitis assessment?
FMGE 2019 - Surgery FMGE Practice Questions and MCQs
Question 1: Which finding is assigned 2 points in the Alvarado scoring system for appendicitis assessment?
- A. Low-grade fever
- B. Leukocytosis (Correct Answer)
- C. Nausea and vomiting
- D. Rebound tenderness
Explanation: **Leukocytosis** - An elevated **white blood cell count** (typically greater than 10,000 cells/mm³) is a significant indicator of inflammation, assigned **2 points** in the Alvarado score. - This finding reflects the body's systemic response to the infection and inflammation associated with **appendicitis**. *Low-grade fever* - A low-grade fever (oral temperature of 37.3-38.0°C) is assigned **1 point** in the Alvarado score. - While indicative of inflammation, it is less specific and less weighted than leukocytosis. *Nausea and vomiting* - These gastrointestinal symptoms are common in appendicitis and are assigned **1 point** in the Alvarado score. - They are non-specific and can be present in many other abdominal conditions. *Rebound tenderness* - This clinical sign, indicating **peritoneal irritation**, is assigned **1 point** in the Alvarado score. - It is a physical exam finding, not a laboratory finding, and suggests localized inflammation.
