FMGE 2019 Practice Questions

Q: Testicular artery is a branch of -

Abdominal aorta. ***Abdominal aorta*** - The **testicular arteries**, also known as **gonadal arteries**, originate directly from the anterior aspect of the **abdominal aorta**. - They typically arise just inferior to the **renal arteries** at the level of the second lumbar vertebra (L2) and descend to supply the testes. *Common iliac artery* - The common iliac artery is a terminal branch of the **abdominal aorta**, but it gives rise to the internal and external iliac arteries, not directly the testicular artery. [2] - It bifurcates at the level of the sacroiliac joint. [3] *External iliac artery* - The external iliac artery primarily supplies the **lower limb** and gives off the inferior epigastric and deep circumflex iliac arteries. [1] - It does not directly provide branches to the testes. *Internal iliac artery* - The internal iliac artery primarily supplies the **pelvic organs**, gluteal region, and perineum. - While it has numerous branches, none of them are the main gonadal arteries; it contributes to the blood supply of the reproductive organs through other smaller branches. [3]

Q: Trigone of bladder is derived from?

Distal part of Mesonephric duct. Distal part of Mesonephric duct - The **trigone of the bladder** develops from the **caudal (distal) ends of the mesonephric ducts**, which are absorbed into the posterior wall of the forming bladder. - The mesonephric duct origin contributes to the **smooth muscle** of the trigone, giving it distinct structural characteristics compared to the rest of the bladder wall. - The trigone appears as a smooth triangular area bounded by the two ureteric orifices and the internal urethral orifice [1]. *Ventral part of Urogenital sinus* - The **ventral part of the urogenital sinus** primarily forms the **fundus and body of the urinary bladder**, but not the trigone. - This region undergoes differentiation to form the majority of the bladder's wall and provides the epithelial lining for the entire bladder including the trigone. *Distal part of Paramesonephric duct* - The **paramesonephric ducts (Müllerian ducts)** are primarily involved in the development of the female reproductive tract, forming the **fallopian tubes, uterus, and upper vagina**. - They do not contribute to the formation of the urinary bladder or its trigone. *Ventral part of Mesonephric duct* - While the mesonephric ducts are crucial, it is specifically the **distal (caudal) ends** that are incorporated into the bladder to form the trigone, not merely the general ventral part. - The more proximal parts of the mesonephric ducts in males develop into structures like the **epididymis, v\as deferens, seminal vesicles, and ejaculatory ducts**.

Q: The contraceptive which is contraindicated in DVT is?

OCP. ***OCP*** - **Oral contraceptive pills (OCPs)**, especially those containing estrogen, increase the risk of **venous thromboembolism (VTE)**, including deep vein thrombosis (DVT). - Estrogen promotes a **hypercoagulable state** by increasing clotting factors and decreasing natural anticoagulants. *Barrier method* - **Barrier methods** like condoms or diaphragms are non-hormonal and act physically to prevent sperm from reaching the egg. - They have **no systemic effects** on coagulation and are safe for individuals with DVT. *Non hormonal IUCD* - **Non-hormonal intrauterine contraceptive devices (IUCDs)**, such as copper IUCDs, prevent conception primarily by causing a local inflammatory reaction in the uterus. - They do not release hormones and therefore **do not affect coagulation** or increase DVT risk. *Billing's method* - The **Billing's ovulation method** (cervical mucus method) is a natural family planning technique based on observing changes in cervical mucus. - It involves no medications or devices and thus has **no impact on DVT risk**.

Q: For severe acute malnutrition in children (6-59 months), MAC will be less than

11.5 cm. ***11.5 cm*** - A **Mid-Upper Arm circumference (MUAC) below 11.5 cm** is a key diagnostic criterion for **severe acute malnutrition (SAM)** in children aged 6-59 months. - This measurement is a simple and effective screening tool in resource-limited settings to identify children at high risk of mortality due to malnutrition [1]. *13.5 cm* - A MUAC of 13.5 cm or greater is generally considered **nutritionally healthy** for children in this age group, indicating adequate muscle and fat reserves. - This measurement would typically rule out severe acute malnutrition and often even moderate malnutrition. *12.5 cm* - A MUAC between 11.5 cm and 12.5 cm is typically indicative of **moderate acute malnutrition (MAM)**, not severe acute malnutrition. - While concerning, it suggests a less critical nutritional status compared to a MUAC below 11.5 cm. *14.5 cm* - A MUAC of 14.5 cm or greater is well within the healthy range for children aged 6-59 months, indicating **good nutritional status**. - This measurement would suggest no signs of acute malnutrition.

Q: Which of the following drug causes postural hypotension commonly?

Alpha blocker. ***Alpha blocker*** - **Alpha-1 adrenergic blockers** cause common postural hypotension by blocking **alpha-1 receptors** on vascular smooth muscle, leading to vasodilation and reduced peripheral vascular resistance. - This vasodilation, especially in the upright position, can cause blood to pool in the lower extremities, decreasing venous return to the heart and thus lowering blood pressure. *Angiotensin receptor blockers* - These drugs block the effects of **angiotensin II**, leading to vasodilation and decreased aldosterone secretion, typically causing a more gradual and less pronounced drop in blood pressure. - While they can cause hypotension, **postural hypotension** is less common and usually less severe compared to alpha blockers due to their different mechanism of action and less abrupt vasodilation. *Beta blocker* - **Beta-blockers** primarily reduce heart rate and myocardial contractility, thereby decreasing cardiac output, which can contribute to generalized hypotension. - They do not directly cause significant **vasodilation** in the same manner as alpha-blockers, making postural hypotension less common unless there are other contributing factors. *ACE inhibitor* - **ACE inhibitors** prevent the conversion of angiotensin I to **angiotensin II**, leading to vasodilation and reduced aldosterone. - They can cause hypotension, especially with the first dose or in volume-depleted patients, but **postural hypotension** is typically less frequent and severe than with alpha-blockers.

Q: Testosterone is secreted by:

Leydig cell. ***Leydig cell*** - **Leydig cells** are located in the **interstitial tissue** of the testes and are responsible for producing **testosterone** in response to **luteinizing hormone (LH)** stimulation. - They are the primary source of androgens in males, crucial for the development of male secondary sexual characteristics and spermatogenesis. *Granulosa cell* - **Granulosa cells** are found in the **ovarian follicles** and are primarily involved in the production of **estrogen** and **progesterone** in females. - They surround the oocyte and convert androgens (produced by theca cells) into estrogens. *Theca cells* - **Theca cells** are found in the **ovarian follicles** and produce **androgens** (mainly androstenedione) in response to **LH** stimulation. - These androgens are then converted to estrogens by the adjacent granulosa cells through aromatization. - While they produce androgens, they are not the primary source of testosterone in the body. *Sertoli cell* - **Sertoli cells** are located in the **seminiferous tubules** of the testes and provide structural and metabolic support for **spermatogenesis**. - They produce substances like **androgen-binding protein**, inhibin, and Müllerian inhibiting factor, but they do not secrete testosterone.

Q: Which of the following is not a formal thought disorder?

Delusion. ***Delusion*** - A **delusion** is a **fixed, false belief** that is firmly held despite clear evidence to the contrary and is not consistent with the person's cultural or religious background. It is a **disorder of thought content**, not thought form or process. - While delusions are a hallmark symptom of many psychotic disorders, they represent what a person thinks, rather than how they think. *Neologism* - **Neologism** refers to the **creation of new, nonsensical words or phrases** that are intelligible only to the person coining them. - This is a formal thought disorder because it reflects a break in the conventional structure and coherence of language. *Derailment* - **Derailment**, also known as **loose associations**, is a thought disorder where the person's thoughts shift from one topic to another in a way that is loosely connected or completely unrelated. - This represents a disruption in the logical flow and organization of ideas, making it a formal thought disorder. *Tangentiality* - **Tangentiality** is a thought disorder where the person **strays from the main topic** and never returns to the original point or answers the question asked. - It reflects an inability to maintain focused thought and is a formal thought disorder related to the process of thinking.

Q: Comment on the diagnosis of the CT chest image shown below.

Aortic dissection. ***Aortic dissection*** - The image shows a **flap-like linear structure** within the aortic lumen, which represents an **intimal flap** separating the true and false lumens, characteristic of an aortic dissection. - This condition involves a tear in the **aortic intima**, allowing blood to flow between the layers of the aortic wall, a serious and life-threatening event. *Aortic aneurysm* - An aortic aneurysm would present as a **focal dilation** of the aorta, exceeding its normal diameter, without evidence of an intimal flap or separate lumens. - While it can be a precursor to dissection, an aneurysm itself does not show the distinct internal flap seen in dissection. *Pulmonary embolism* - Pulmonary embolism involves a **filling defect** within the pulmonary arteries, typically caused by a blood clot, and would be located in the pulmonary vasculature, not the aorta. - The image clearly depicts an issue with the aorta, not the pulmonary arteries. *Cardiac myxoma* - A cardiac myxoma is a **benign tumor** typically found in the atria of the heart, most commonly the left atrium. - It would appear as an intracardiac mass and not as an intimal flap within the aortic lumen.

Q: In which location is a transplanted kidney typically placed?

Iliac fossa. ***Iliac fossa*** - The **iliac fossa** is the standard site for kidney transplantation due to its accessibility and the proximity of suitable blood vessels (iliac artery and vein) for anastomosis. [1] - Placing the kidney here allows for easier access for potential biopsies and monitoring. *Retroperitoneal space* - The patient's native kidneys are located in the **retroperitoneal space**, but a transplanted kidney is typically placed in a more accessible anterior location. - Transplanting a kidney into the retroperitoneal space would be a more complex and invasive procedure due to the depth and surrounding structures. *Hypogastric region* - While the iliac fossa is part of the broader hypogastric region, the term **hypogastric region** is less specific for the precise anatomical location of kidney transplantation. - The iliac fossa specifically refers to the concave surface of the ilium, which provides a suitable bed for the donated kidney. *Kidney fossa* - **Kidney fossa** is not a formally recognized anatomical term for a specific site of kidney transplantation. - The term "fossa" describes a depression or hollow, but in the context of transplantation, the iliac fossa is the correct anatomical landmark used.
