FMGE 2019 Practice Questions

Q: Which of the following is the safety muscle of tongue?

Genioglossus. ***Genioglossus*** - The **genioglossus muscle** is considered the safety muscle of the tongue because its contraction pulls the tongue forward, preventing it from falling backward and **obstructing the airway**, especially during sleep or in an unconscious state. - Its forward action is crucial in maintaining a **patent airway** [1]. *Hyoglossus* - The **hyoglossus muscle** depresses and retracts the tongue. - Its primary action is not to prevent airway obstruction, but rather for **tongue movement** during speech and swallowing. *Styloglossus* - The **styloglossus muscle** retracts and elevates the tongue. - It helps in shaping the tongue for **swallowing and speech**, but does not have a primary role in airway patency. *Palatoglossus* - The **palatoglossus muscle** elevates the posterior part of the tongue and depresses the soft palate. - It is involved in initiating **swallowing** and separating the oral cavity from the pharynx, not in preventing airway collapse.

Q: Which bases are present in human DNA?

Adenine-guanine-cytosine-thymine. ***Adenine- guanine-cytosine-thymine*** - DNA (deoxyribonucleic acid) in humans, and most other organisms, is composed of four nitrogenous bases: **adenine (A), guanine (G), cytosine (C), and thymine (T)**. - These bases are paired specifically: **adenine with thymine (A-T)** and **guanine with cytosine (G-C)**, forming the rungs of the DNA double helix. *None of the above* - This option is incorrect because there is a definitive set of bases that make up human DNA, as described in the correct option. - The fundamental building blocks of human DNA are well-established and universally recognized in biology. *Adenine-guanine- cytosine-uracil* - This list of bases is characteristic of **RNA (ribonucleic acid)**, not DNA. - In RNA, **uracil (U)** replaces thymine (T), meaning RNA contains adenine (A), guanine (G), cytosine (C), and uracil (U). *Adenine-guanine-thiamine- uracil* - This option incorrectly includes **thiamine**, which is a **vitamin (B1)** and not a nitrogenous base found in nucleic acids. - It also incorrectly includes **uracil**, which is found in RNA, not DNA.

Q: A patient who recently got a denture fitted is found to have oral thrush that bleeds on scraping. What is the causative agent for this condition?

Candida. ***Candida*** - **Oral thrush** (candidiasis) is a common opportunistic fungal infection, especially in individuals with **dentures**, which create a warm, moist environment conducive to candidal growth. - The characteristic presentation includes **white patches** on the oral mucosa that, when scraped, reveal an **erythematous** (red) or **bleeding** surface. *Diphtheria* - Diphtheria causes a **pseudomembrane** in the throat that is tough, grayish, and hard to remove, but it's not typically associated with denture use or easy bleeding on scraping. - It is caused by the bacterium *Corynebacterium diphtheriae* and is accompanied by **severe systemic toxicity**, unlike the localized oral thrush. *Staph Aureus* - *Staphylococcus aureus* can cause various infections, but it is not typically associated with the characteristic **white, easily scrapable lesions** of oral thrush. - Oral *Staph aureus* infections might present as **impetigo** periorally or **abscesses**, neither of which fits the clinical description. *Strep Mutans* - *Streptococcus mutans* is primarily known for its role in **dental caries** (cavities) due to acid production from sugar fermentation. - It is not the causative agent for **oral thrush** or the described white, bleeding lesions on scraping.

Q: A young boy came to OPD with complaints of difficulty in breathing. On examination, bilateral polyps were found. On aspiration, bleeding was seen. What will be the initial management?

Topical corticosteroids. ***Topical corticosteroids*** - **Topical corticosteroids** are the **first-line medical management** for **nasal polyps**, helping to reduce inflammation and shrink polyp size. - They work by reducing local inflammation and edema, improving nasal airway patency and breathing. - **Important note**: The presence of **bleeding on aspiration** suggests a **vascular lesion** (such as juvenile nasopharyngeal angiofibroma in young males), which would require **imaging (CT/MRI) before any intervention** and **no biopsy** due to hemorrhage risk. However, if these are inflammatory polyps, topical steroids remain the initial medical management. *Antihistaminic* - **Antihistamines** are not first-line treatment for nasal polyps, as polyps are primarily an **eosinophilic inflammatory condition** rather than a simple IgE-mediated allergic reaction. - While antihistamines may help with associated allergic rhinitis symptoms, they do **not shrink polyps** or address the underlying inflammatory pathology. *Septoplasty* - **Septoplasty** is a surgical procedure to correct a **deviated nasal septum**, not for treating nasal polyps. - This would not address the bilateral polyps causing difficulty in breathing. *I and D* - **Incision and drainage (I&D)** is performed for abscesses or pus collections, which is not the presentation here. - Nasal polyps are benign inflammatory masses, not infectious collections requiring drainage.

Q: Reversible dementia is seen in?

Hypothyroidism. ***Hypothyroidism*** - **Hypothyroidism** can lead to cognitive impairment, including memory loss, slowed thinking, and executive dysfunction, which are reversible with appropriate **thyroid hormone replacement therapy**. - This condition is often characterized by other systemic symptoms like fatigue, weight gain, and cold intolerance, which also improve with treatment. *Pick's disease* - **Pick's disease** is a type of **frontotemporal dementia** caused by progressive degeneration of brain cells, primarily in the frontal and temporal lobes. - It is a **neurodegenerative** disorder, meaning it is progressive and irreversible. *Alzheimer's disease* - **Alzheimer's disease** is the most common cause of dementia, characterized by the accumulation of **amyloid plaques** and **neurofibrillary tangles** in the brain [1]. - It is a **progressive and irreversible neurodegenerative disease** with no cure [2]. *Subacute demyelination of spinal cord* - **Subacute demyelination of the spinal cord** typically refers to conditions like **subacute combined degeneration** due to **vitamin B12 deficiency** [1]. - While this can cause neurological symptoms, including cognitive changes, its primary impact is on the spinal cord and peripheral nerves, and "dementia" in the classic sense is not the primary or defining feature of spinal cord demyelination itself, although B12 deficiency can cause broader cognitive issues [1].

Q: SARS is caused by novel variant of?

Coronavirus. ***Coronavirus*** - **Severe Acute Respiratory Syndrome (SARS)** is caused by a novel strain of **coronavirus**, specifically SARS-CoV. - Coronaviruses are a large family of viruses known to cause respiratory illnesses ranging from the common cold to more severe diseases. *Togavirus* - Togaviruses are a family of **RNA viruses** that include **Rubella virus** and **Alphaviruses** (e.g., Eastern equine encephalitis virus). - They are typically transmitted by **arthropod vectors** and do not cause SARS. *Lyssavirus* - Lyssaviruses belong to the family Rhabdoviridae and are the causative agents of **rabies**, a severe neurological disease. - They are transmitted through the bite of an infected animal and are not associated with SARS. *Poxvirus* - Poxviruses are a family of **DNA viruses** that include **Variola virus** (smallpox) and **Monkeypox virus**. - They are known for causing characteristic skin lesions and are not responsible for SARS.

Q: Appropriate treatment for mild congenital ptosis?

LPS Resection. ***LPS Resection*** - **LPS (levator palpebrae superioris) resection/advancement** is the most common surgical treatment for congenital ptosis, especially in mild to moderate cases. - This procedure strengthens the levator muscle, improving eyelid position and is appropriate when the **levator function is good** (typically greater than 4mm). *Frontalis sling procedure* - The **frontalis sling procedure** is generally reserved for severe congenital ptosis with poor levator function (<4mm) or in cases where the levator muscle is absent or highly dysfunctional. - It uses the frontalis muscle to lift the eyelid indirectly, which is less ideal for mild ptosis. *Antibiotics and hot compression* - **Antibiotics and hot compression** are treatments for infectious or inflammatory conditions of the eyelid, such as a **hordeolum** (stye) or **chalazion**. - They are not effective treatments for anatomical defects like congenital ptosis, which requires surgical intervention. *Wedge resection of conjunctiva* - **Wedge resection of the conjunctiva** might be used in some cases of conjunctival prolapse or for correction of specific conjunctival lesions or abnormalities. - It is not a standard or appropriate treatment for congenital ptosis.

Q: Which of the following is a feature of Vit B12 deficiency anemia?

All of the options. **All of the options** - **Vitamin B12 deficiency anemia** is a type of **megaloblastic anemia** characterized by impaired DNA synthesis, leading to large, immature red blood cells and neutrophils [1]. - The presence of **macro-ovalocytes** and **hypersegmented neutrophils** are classic hematological features seen on a peripheral blood smear [1]. *Macro-ovalocytes* - **Macro-ovalocytes** are abnormally large, oval-shaped red blood cells, which result from arrested maturation due to the deficiency. - While a hallmark of B12 deficiency, it is not the sole identifying feature, as other megaloblastic anemias can also present with them [2]. *Megaloblastic anemia* - **Megaloblastic anemia** is a broad category of anemia characterized by large, immature, and dysfunctional red blood cells, which is the primary classification for B12 deficiency [2]. - While accurate, it doesn't encompass the specific morphological findings seen in the blood smear of B12 deficiency, unlike the other options. *Hypersegmented neutrophils* - **Hypersegmented neutrophils** are neutrophils with five or more nuclear lobes, a characteristic sign of impaired DNA synthesis affecting granulopoiesis [1]. - This feature is highly specific to **megaloblastic anemias**, distinguishing them from other causes of macrocytosis.

Q: Koplik spots are seen in?

Measles. ***Measles*** - **Koplik spots** are pathognomonic rash that appears as small, white spots with a bluish-white center on an erythematous base on the **buccal mucosa** opposite the second molars. - They typically appear 2-3 days before the onset of the characteristic maculopapular rash, during the **prodromal phase** of measles (rubeola). *Rubella* - Rubella, or **German measles**, presents with a milder rash, **lymphadenopathy**, and mild fever. - It does not cause Koplik spots; instead, **Forchheimer spots** (petechiae on the soft palate) may be seen, but these are less specific. *Mumps* - Mumps is characterized primarily by **parotitis** (swelling of the salivary glands), fever, and headache. - It does not present with Koplik spots or any characteristic oral mucosal lesions. *Varicella* - Varicella, or **chickenpox**, is characterized by a **vesicular rash** that progresses from macules to papules to vesicles to crusts, appearing in crops. - It does not involve Koplik spots; the rash is typically generalized and pruritic.

Q: Which of the following is best assessed by FAST USG?

Pericardium. ***Pericardium*** - FAST USG is **most clinically significant** for detecting **pericardial effusions** and **cardiac tamponade** in trauma patients. - The **subxiphoid view** provides **excellent direct visualization** of the heart and pericardial space with minimal interference. - **Small volumes** of pericardial fluid (as little as 50-100 mL) are **clinically significant** and potentially life-threatening, requiring immediate intervention. - Cardiac tamponade is an **immediately reversible cause of shock** that demands urgent diagnosis and pericardiocentesis. - **Sensitivity >90%** for clinically significant pericardial effusions in the trauma setting. *Liver* - FAST assesses the **hepatorenal space (Morison's pouch)** for free fluid, not the liver parenchyma itself. - Requires **larger volumes of free fluid** (>200-500 mL) to be reliably detected in the peritoneal cavity. - Detailed assessment of actual liver injury requires **contrast-enhanced CT imaging**. *Spleen* - FAST evaluates the **splenorenal recess** for free fluid surrounding the spleen, not splenic parenchymal injury. - Detection depends on adequate volume of free fluid being present. - **CT scanning** is superior for defining splenic lacerations, hematomas, and grading injury severity. *Pleural cavity* - While Extended FAST (eFAST) can assess **pleural spaces** for effusion or pneumothorax, this is an **extension** of the standard 4-view FAST protocol. - Standard FAST focuses on the **four primary windows**: pericardial, perihepatic, perisplenic, and pelvic. - **Chest X-ray** and **CT** remain primary modalities for comprehensive thoracic assessment.
