Question 81: Iron absorption is decreased in which of the following?
- A. Amla
- B. Lemon
- C. Tea (Correct Answer)
- D. Sprouting
Explanation: ***Tea*** - Contains **tannins and polyphenols** that bind to non-heme iron in the gastrointestinal tract - Forms **insoluble iron complexes** that cannot be absorbed - Can reduce iron absorption by **60-70%** when consumed with meals - Most significant dietary inhibitor of iron absorption *Incorrect: Amla* - Indian gooseberry is rich in **vitamin C (ascorbic acid)** - Vitamin C **enhances iron absorption** by reducing ferric (Fe³⁺) to ferrous (Fe²⁺) form - Also prevents formation of insoluble iron compounds *Incorrect: Lemon* - Rich in **vitamin C and citric acid** - Both compounds **enhance iron absorption** significantly - Citric acid chelates iron, keeping it soluble and bioavailable *Incorrect: Sprouting* - **Reduces phytate content** in grains and legumes - Phytates are iron absorption inhibitors - Sprouting therefore **enhances iron bioavailability**

Question 81: Rukmini is attending the village health nutrition and sanitation program day. How frequently is this conducted?
- A. Every month (Correct Answer)
- B. Every 3 months
- C. Every 14 days
- D. Every week
Explanation: ***Every month***- The **Village Health, Nutrition, and Sanitation (VHNS) Day** is a pivotal platform under the **National Health Mission (NHM)** and is officially required to be conducted **monthly** in every village. - This monthly meeting, often held at the Anganwadi Centre, integrates services such as **immunization**, antenatal and postnatal care, growth monitoring, and sanitation awareness, typically involving the **AWW**, **ANM**, and **ASHA**.*Every week*- Weekly scheduling would place an undue burden on field staff like the **ANM** and Medical Officer, who are responsible for covering multiple Sub-centres and villages.- While specific services or training sessions might occur weekly, the full, integrated delivery of the authorized VHNS program interventions is reserved for the designated **monthly VHNS Day**.*Every 14 days*- The established guidelines for the VHNS Day specify a **monthly** event, ensuring regular but feasible service delivery without overwhelming the rural health structure.- Bi-weekly (every 14 days) is not the prescribed national norm for organizing this comprehensive community mobilization and service delivery day.*Every 3 months*- A quarterly (every 3 months) schedule would be considered inadequate for effective monitoring of children's growth, timely completion of the **immunization schedule**, and addressing immediate maternal health needs.- The high-frequency nature of certain health interventions like nutritional supplementation and growth charting necessitates the established **monthly** meeting to track progress and intervene promptly.
Question 82: Arrange the order of the Disaster management cycle
- A. Impact-response-rehabilitation-mitigation (Correct Answer)
- B. Rehabilitation-response-impact-mitigation
- C. Impact-mitigation-response-rehabilitation
- D. Response-disaster-rehabilitation-mitigation
Explanation: ***Impact-response-rehabilitation-mitigation***- The disaster management cycle logically follows the progression from the event itself (**Impact**), immediately followed by addressing the crisis (**Response**), then rebuilding and restoring (**Rehabilitation**), and finally, taking long-term steps to reduce future vulnerability (**Mitigation**).- This sequence captures the critical flow from crisis stabilization (Response) to long-term recovery (Rehabilitation) and future risk reduction (Mitigation).*Rehabilitation-response-impact-mitigation*- This order is incorrect because **rehabilitation** (the recovery phase) must follow the **impact** (the disaster event) and the immediate relief **response**. - The cycle must begin with the occurrence of the event itself (**impact**), which triggers all subsequent management phases.*Response-disaster-rehabilitation-mitigation*- The sequence is flawed because the **response** actions are initiated *after* the **disaster** (or impact) has occurred.- Immediate actions must follow the event, meaning **disaster/impact** must precede the **response** phase.*Impact-mitigation-response-rehabilitation*- This sequence fails because **mitigation** is a long-term strategy for preventing future disasters, which typically occurs before or after the immediate response and recovery, not immediately following the initial **impact**. - The crucial immediate medical and safety interventions (**Response**) must follow the disaster **impact**, before the longer-term **rehabilitation** begins.
Question 83: The needle with the syringe is disposed of in which container?
- A. Red
- B. Blue
- C. Yellow
- D. White (Correct Answer)
Explanation: ***White***- This container is designated specifically for **sharp waste**, including hypodermic needles, fixed-needle syringes, blades, and scalpels, to prevent **needle-stick injuries**.- These containers are required to be **puncture-proof** and tamper-proof to ensure the safe handling of hazardous sharps.*Yellow*- *Yellow* containers are used for **infectious waste**, such as anatomical waste, soiled cotton, dressings, and waste contaminated heavily with blood or body fluids.- Sharps are strictly excluded from yellow bags, which are not designed to withstand **puncture**.*Red*- *Red* containers are designated for **recyclable plastic waste**, including non-sharp items like catheters, tubing, and syringes *without* the needle attached.- If a syringe barrel were being disposed of separately from a detached needle, it would go into the red container, but the combined unit is classified as **sharp waste**.*Blue*- *Blue* containers are designated primarily for **discarded glass items** (like broken bottles or ampules) or sometimes metallic implants.- Although needles are metallic, their primary hazard classification as a 'sharp' mandates disposal in the **puncture-proof White** container.

Optic nerve glioma is seen in?
FMGE 2024 - Ophthalmology FMGE Practice Questions and MCQs
Question 81: A 32-year-old patient presents with blurred vision, photophobia, and mild ocular pain. Examination reveals aqueous flares and keratic precipitates in the anterior chamber. What is the likely diagnosis?
- A. D. Iridocyclitis (Correct Answer)
- B. A. Intermediate uveitis
- C. B. Posterior uveitis
- D. C. Toxoplasma uveitis
Explanation: ***D. Iridocyclitis***- **Iridocyclitis** is the preferred term for **anterior uveitis**, which involves inflammation of the iris and ciliary body.- The hallmark signs of **aqueous flares** (protein and cells in the anterior chamber) and **keratic precipitates** (inflammatory cell deposits on the corneal endothelium) confirm that the inflammation is localized to the **anterior chamber**.*A. Intermediate uveitis*- Characterized by inflammation primarily in the **vitreous** and **pars plana**, often referred to as *vitritis*.- While it causes blurred vision and floaters, the anterior chamber signs like *aqueous flares* and *keratic precipitates* are not the dominant features; fundoscopy may reveal **snowbanking**.*B. Posterior uveitis*- Involves inflammation of the **retina** and/or **choroid** (e.g., retinitis or choroiditis), often causing significant central vision loss and scotomas.- The primary findings are located in the posterior segment (fundus lesions), and the anterior chamber is often **quiet** or shows only mild reaction.*C. Toxoplasma uveitis*- This is a specific cause of **posterior uveitis**, typically presenting as a focus of **necrotizing retinitis** adjacent to an old, pigmented scar.- Although it can cause a *secondary* anterior chamber reaction, the primary diagnostic feature is the specific retinal lesion, which is not mentioned in this presentation.
Question 82: Optic nerve glioma is seen in?
- A. A. NF-1 (Correct Answer)
- B. B. Tuberous sclerosis
- C. C. NF-2
- D. D. Schwannoma
Explanation: ***NF-1***- **Optic pathway gliomas (OPGs)** are hallmark features of **Neurofibromatosis type 1 (NF-1)**, an autosomal dominant disorder caused by a mutation in the *NF1* gene on chromosome 17.- OPGs are typically low-grade **pilocytic astrocytomas** and commonly present in children under 6 years of age. *Tuberous sclerosis*- The most characteristic CNS tumor in patients with **Tuberous Sclerosis Complex (TSC)** is the **subependymal giant cell astrocytoma (SEGA)**, usually near the foramen of Monro.- TSC is associated with **retinal astrocytic hamartomas** (phakomas), not primary optic nerve gliomas. *NF-2*- **Neurofibromatosis type 2 (NF-2)** is characterized by **bilateral vestibular schwannomas** (acoustic neuromas), which is the diagnostic criterion.- Other common tumors in NF-2 include meningiomas, ependymomas, and other cranial or spinal schwannomas, but rarely **optic nerve gliomas**. *Schwannoma*- A **schwannoma** is a tumor arising from Schwann cells, often seen on peripheral nerves or cranial nerves (like CN VIII in NF-2).- The optic nerve is considered part of the CNS (a tract of the diencephalon) and is myelinated by oligodendrocytes, meaning **schwannomas** are not primary tumors of the optic nerve itself.

Question 81: A patient experienced a fall onto an outstretched hand, and an X-ray revealed a fracture of the base of the first metacarpal with accompanying subluxation at the carpometacarpal (CMC) joint. Define this type of fracture.
- A. B. Scaphoid fracture
- B. C. Reverse Colle’s fracture
- C. A. Bennett’s fracture (Correct Answer)
- D. D. Colle’s fracture
Explanation: ***Bennett’s fracture***- This is a characteristic **intra-articular fracture** at the base of the **first metacarpal**, which extends into the carpometacarpal (CMC) joint.- The main metacarpal shaft is typically pulled proximally and radially by the **Abductor Pollicis Longus** tendon, leading to the obligatory **subluxation** described.*Scaphoid fracture*- This injury involves one of the **carpal bones** (the scaphoid) in the wrist, not the metacarpal bases or MCP/CMC joints.- Although commonly caused by a fall onto an outstretched hand (FOOSH), its primary presentation is tenderness in the **anatomical snuffbox**.*Reverse Colle’s fracture*- This fracture, also known as **Smith’s fracture**, affects the **distal radius** in the forearm.- It is defined by the **volar** (palmar) displacement of the distal radial fragment, opposite to the displacement seen in a typical Colle's fracture.*Colle’s fracture*- This common FOOSH injury affects the **distal radius** bones in the forearm, not the hand joints.- It is defined by the characteristic **dorsal** (posterior) displacement of the distal radial fragment, often creating a 'dinner fork' deformity.
Question 82: Identify the type of fracture in a patient who sustained a road traffic accident resulting in fractures of both the tibia and fibula.
- A. Depressed skull fracture
- B. Patella sleeve fracture
- C. Bumper Fracture (Correct Answer)
- D. Cervical fracture
Explanation: ***Bumper Fracture*** - A **bumper fracture** refers to fractures of the **tibia and fibula** sustained when a pedestrian is struck by a vehicle bumper during a **road traffic accident**. - The term typically describes **mid-shaft or proximal shaft fractures** of both bones caused by direct lateral impact from a car bumper. - This matches the clinical scenario of **both tibia and fibula fractures** following RTA, making it the correct answer. - Note: The term can also refer specifically to lateral tibial plateau fractures, but in the context of "both bones" being fractured, it refers to the shaft fracture pattern. *Patella sleeve fracture* - This is a rare **avulsion fracture** seen almost exclusively in **children and adolescents**, involving the superior or inferior pole of the patella. - It results from forceful contraction of the **quadriceps** or sudden loading, causing avulsion of the cartilaginous sleeve. - This does not involve both tibia and fibula, making it incorrect for this scenario. *Depressed skull fracture* - This fracture involves the **calvarium (skull)** where bone fragments are pushed inward toward the brain. - While RTAs can cause head injuries, the question specifically describes fractures of the **tibia and fibula** (lower limb bones), not skull injury. *Cervical fracture* - Refers to fractures involving the **cervical vertebrae** in the neck region. - Although cervical spine injuries occur in RTAs, this does not match the clinical scenario of **lower limb long bone fractures** (tibia and fibula).

2 questionsWhich of the following is the investigation of choice for CML?
A 5-year-old child presents with a lesion in the right eye. Histopathology reveals the presence of Flexner-Wintersteiner rosettes. What is the likely diagnosis?
FMGE 2024 - Pathology FMGE Practice Questions and MCQs
Question 81: Which of the following is the investigation of choice for CML?
- A. LAP score
- B. FISH
- C. Molecular testing (BCR-ABL PCR)
- D. Karyotyping (Correct Answer)
Explanation: ***Karyotyping (Conventional Cytogenetics)*** - **Gold standard** and investigation of choice for CML diagnosis - Detects the **Philadelphia chromosome t(9;22)** present in 95% of CML cases [2] - WHO diagnostic criterion for CML - Can identify additional chromosomal abnormalities with prognostic significance - Provides complete chromosomal analysis *FISH (Fluorescence In Situ Hybridization)* - Used as **complementary technique** when karyotyping fails or metaphases are inadequate - More sensitive than karyotyping but NOT the first-line investigation [2] - Useful for monitoring minimal residual disease - Cannot detect additional chromosomal abnormalities *Molecular testing (BCR-ABL PCR)* - Used for **monitoring treatment response** and detecting minimal residual disease [1] - Highly sensitive and quantitative [1] - Not the initial investigation of choice for diagnosis *LAP score (Leukocyte Alkaline Phosphatase)* - Used to differentiate CML from leukemoid reaction - Low in CML, high in leukemoid reaction - Older diagnostic tool, now largely replaced by molecular methods - Not the investigation of choice **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Genetic Disorders, pp. 185-187. [2] Cross SS. Underwood's Pathology: A Clinical Approach. 6th ed.

Question 82: A 5-year-old child presents with a lesion in the right eye. Histopathology reveals the presence of Flexner-Wintersteiner rosettes. What is the likely diagnosis?
- A. Optic nerve glioma
- B. Rhabdomyosarcoma
- C. Retinoblastoma (Correct Answer)
- D. Ocular melanoma
Explanation: ***Retinoblastoma*** - The presence of **Flexner-Wintersteiner rosettes**, which are characteristic arrangements of columnar cells around a central lumen, is the pathognomonic histological feature of well-differentiated **retinoblastoma** [1].- This tumor is the most common **intraocular malignancy** of childhood, typically presenting as **leukocoria** (white pupillary reflex) in children under the age of 5. *Optic nerve glioma*- These tumors are typically low-grade astrocytomas, most frequently **pilocytic astrocytomas**, characterized by glial cells, not neuronal-like rosettes.- They involve the **optic nerve** itself and are strongly associated with **Neurofibromatosis type 1 (NF1)**. *Rhabdomyosarcoma*- This is the most common **pediatric orbital malignancy** (outside the globe), typically presenting with rapid onset of **proptosis** (exophthalmos) and eyelid swelling.- Histologically, it is a small round blue cell tumor derived from mesenchymal cells, showing **rhabdomyoblasts**, and does not form Flexner-Wintersteiner rosettes. *Ocular melanoma*- This malignancy is extremely rare in the pediatric population and is overwhelmingly a disease of **adults**.- Histopathology shows malignant cells derived from **melanocytes** (spindle or epithelioid cells) containing melanin, lacking photoreceptor differentiation structures like rosettes. **References:** [1] Kumar V, Abbas AK, et al..
