INI-CET 2022 Practice Questions

Q: In all the following places, hand rub can be used according to standard hand hygiene protocol, except...

If the hands are visibly soiled. ***If the hands are visibly soiled*** - **Hand rub (alcohol-based hand rub)** is ineffective at removing gross contamination and organic matter from visibly soiled hands. - In such cases, **hand washing with soap and water** is mandatory to physically remove dirt, debris, and microorganisms. *While moving from a contaminated site to a clean site during patient care* - **Hand rub** is appropriate in this scenario to prevent the transfer of microorganisms from a potentially contaminated body site or object to another, cleaner area of the patient. - This is part of the "5 Moments for Hand Hygiene" to ensure **patient safety** and prevent **cross-contamination**. *During direct patient contact* - **Hand rub** can be used before and after direct patient contact if hands are not visibly soiled, as it provides rapid and effective decontamination. - This practice is crucial for minimizing the transmission of **healthcare-associated infections**. *Before donning gloves* - **Hand rub** should be performed before donning gloves, especially when performing procedures that involve contact with mucous membranes, non-intact skin, or sterile sites. - This ensures that hands are clean underneath the gloves, providing an additional layer of **infection prevention**.

Q: Kassowitz rule is related to:

Congenital syphilis. ***Congenital syphilis*** - The **Kassowitz rule** specifically describes the high rate of perinatal mortality (abortion, stillbirth, or death shortly after birth) in cases of untreated maternal syphilis, especially during early stages of infection. - It highlights that the risk is highest when the mother acquires syphilis shortly before or during pregnancy, leading to severe fetal disease. *Primary syphilis* - This stage is characterized by a **chancre** at the site of infection and is the initial presentation in the infected individual, not directly related to fetal outcomes. - While primary syphilis in the mother can lead to congenital syphilis, the Kassowitz rule itself describes the outcome of congenital infection, not the primary infection in the mother. *Latent syphilis* - **Latent syphilis** refers to a stage where the infection is present but asymptomatic, potentially for years. - While it can be transmitted vertically and lead to congenital syphilis, the Kassowitz rule specifically quantifies the mortality risk of congenital syphilis, not the mother's latent infection itself. *Secondary syphilis* - This stage involves a systemic rash and other widespread symptoms in the infected individual, appearing weeks to months after the chancre. - Though highly infectious and a significant risk for vertical transmission, the rule focuses on the severe consequences *for the fetus* when congenital syphilis occurs, not the symptoms of secondary syphilis in the mother.

Q: Identify the injury pattern given in the image.

Ligature mark. ***Ligature mark*** - A **ligature mark** is a depression or furrow left on the skin, typically around the neck, caused by a cord, rope, or other constricting material. - This type of mark is indicative of strangulation or hanging, where the pressure of the ligature leaves a distinct impression on the skin. *Graze abrasion* - A **graze abrasion** involves superficial scraping of the outer layers of the skin due to tangential force. - It often appears as a broad, irregular area of denuded skin, unlike the linear, defined mark seen in the image. *Imprint abrasion* - An **imprint abrasion** occurs when a patterned object presses against the skin, leaving a distinctive impression of its surface. - While it involves a pattern, it is typically a broader contact area rather than a narrow, constricting line. *Pressure abrasion* - A **pressure abrasion** results from sustained pressure on a small area of skin, often over a bony prominence. - While it involves pressure, it usually leads to localized skin damage (e.g., decubitus ulcer formation) rather than the circumferential marking of a ligature.

Q: Hooch tragedy is related to:

Methanol. ***Methanol*** - **Hooch tragedy** refers to incidents of mass poisoning caused by the consumption of adulterated alcoholic beverages, most commonly with **methanol**. - **Methanol poisoning** leads to severe metabolic acidosis, visual disturbances, and organ damage, often resulting in death or permanent disability. *Mercury* - **Mercury poisoning** is typically associated with exposure to elemental mercury, inorganic mercury salts, or organic mercury compounds, leading to neurological and renal symptoms. - It is not directly related to the "hooch tragedy" involving adulterated alcohol. *Ethanol* - **Ethanol** is the type of alcohol consumed in alcoholic beverages and is not typically associated with the "hooch tragedy" unless consumed excessively or in combination with other substances. - While excessive ethanol consumption can lead to **alcohol poisoning**, it does not cause the specific toxic reactions seen in hooch tragedies. *Phosphorus* - **Phosphorus poisoning** can occur from exposure to white phosphorus or ingestion of various phosphorus-containing compounds, affecting multiple organ systems including the liver and cardiovascular system. - It is not a common adulterant in alcoholic beverages and is unrelated to hooch tragedies.

Q: Seminal vesicles and vas deferens would be bilaterally absent congenitally in which of the following conditions?

Cystic fibrosis. ***Cystic fibrosis*** - **Congenital bilateral absence of the vas deferens (CBAVD)** is found in over 95% of males with cystic fibrosis, often leading to infertility. - This condition results from mutations in the **CFTR gene**, which is responsible for chloride transport, causing thick, viscous secretions that block or prevent the development of these structures. *Kartagener syndrome* - This syndrome is a subgroup of **primary ciliary dyskinesia**, characterized by a triad of *situs inversus*, chronic sinusitis, and bronchiectasis. - While it causes **infertility due to immotile sperm**, the male reproductive tract organs like the vas deferens and seminal vesicles are typically present. *Klinefelter syndrome* - Individuals with Klinefelter syndrome have a **47,XXY karyotype** and typically present with small testes, azoospermia, and hypogonadism [1]. - However, the **vas deferens and seminal vesicles are usually present**, though they may be underdeveloped or dysfunctional. *Kallmann syndrome* - This is a form of **hypogonadotropic hypogonadism** associated with anosmia or hyposmia (impaired sense of smell). - It results from a failure of GnRH-producing neurons to migrate to the hypothalamus, affecting hormone production, but the **anatomical structures of the vas deferens and seminal vesicles are usually intact**.

Q: All the following are criteria for SIRS, except

Systolic blood pressure 90/min* - An elevated **heart rate** (tachycardia) is a common physiological response to systemic stress and inflammation. - This criterion fulfills one of the four clinical parameters to diagnose **SIRS**. *Respiratory rate >20 bpm* - An increased **respiratory rate** (tachypnea) reflects the body's attempt to compensate for metabolic acidosis or increased oxygen demand during a systemic inflammatory response. - This criterion is one of the four clinical parameters used to diagnose **SIRS**. *Temperature >38 degree Celsius or 38°C) and **hypothermia** (<36°C) are indicators of a systemic inflammatory response, as the body's thermoregulation is affected [1]. - This criterion is one of the four principal parameters used to diagnose **SIRS** [1].

Q: Which hormone is secreted by the placenta?

hCG. ***hCG*** - **Human Chorionic Gonadotropin (hCG)** is produced by the **syncytiotrophoblast** of the placenta shortly after implantation. - Its primary role is to maintain the **corpus luteum**, ensuring continued production of **progesterone** to support the pregnancy. *GnRH* - **Gonadotropin-releasing hormone (GnRH)** is secreted by the **hypothalamus** in the brain, not the placenta. - It stimulates the pituitary gland to release FSH and LH. *FSH* - **Follicle-stimulating hormone (FSH)** is produced by the **anterior pituitary gland**. - It plays a crucial role in ovarian follicular development in females and spermatogenesis in males. *LH* - **Luteinizing hormone (LH)** is also secreted by the **anterior pituitary gland**. - Its functions include triggering ovulation in females and stimulating testosterone production in males.

Q: The most common pattern of involvement in Pott's spine is

Paradiscal. ***Paradiscal*** - In **Pott's spine (tuberculous spondylitis)**, the infection typically starts in the anterior inferior aspect of the vertebral body and spreads to the adjacent disc space, making the **paradiscal** area the most common site of involvement. - This pattern is due to the rich **paradiscal vascular supply**, which facilitates the hematogenous spread of *Mycobacterium tuberculosis* to these regions. *Central* - **Central involvement** refers to the lesion being primarily located within the center of the vertebral body, which is less common in Pott's spine as the bacteria typically target the highly vascularized anterior and inferior margins. - While central lesions can occur, they are not the predominant pattern seen in initial stages of tuberculous spondylitis. *Posterior* - **Posterior involvement** usually refers to involvement of the posterior vertebral elements such as the neural arch, laminae, or spinous processes. - This type of involvement is **rare** in Pott's spine and is generally seen in very advanced or disseminated disease. *Anterior* - While the infection often begins in the anterior part of the vertebral body, the term **anterior** alone is less specific than "paradiscal" and doesn't fully capture the predominant involvement of the adjacent disc space. - The disease's characteristic spread across the disc space to an adjacent vertebra is a key feature of the paradiscal pattern, leading to **kyphosis** and vertebral collapse.

Q: Which of these is the most life-threatening injury that can be identified by assessing the breathing component of the patient?

Tension pneumothorax. ***Tension pneumothorax*** - A tension pneumothorax is a **life-threatening condition** identified during the breathing assessment, as it severely impairs ventilation and causes **hemodynamic instability** by compressing major vessels. - Key signs include absent breath sounds on the affected side, **tracheal deviation**, and **hypotension** due to mediastinal shift. *Blunt cardiac injury* - While serious, blunt cardiac injury is typically identified during the **circulation assessment**, with signs like arrhythmias, hypotension, or cardiac tamponade. - Its direct impact on breathing is less immediate compared to a tension pneumothorax. *Cervical spine injury* - A cervical spine injury can affect breathing if it involves the **phrenic nerve** (C3-C5), leading to respiratory paralysis, but this is assessed during the **disability component** or secondary survey for neurological deficits. - It does not directly cause an acute, life-threatening compromise of lung function discernible primarily through a breathing assessment like a tension pneumothorax. *Laryngotracheal injury* - A laryngotracheal injury primarily affects the **airway component** (A in ABCDE), leading to immediate obstruction or stridor. - While critical, it is distinct from problems with the lungs' ability to expand or perform gas exchange, which are assessed under breathing.

Q: A 32-year-old female patient with Graves' disease with eye signs and enlarged thyroid planned for a total thyroidectomy. What can be given in the preoperative period to reduce intraoperative bleeding in the patient?

Potassium iodide. ***Potassium iodide*** - **Potassium iodide** (e.g., Lugol's solution) is given preoperatively to patients with Graves' disease undergoing thyroidectomy because it **decreases the vascularity** of the thyroid gland, thereby reducing intraoperative bleeding. - It also helps to **block the release of thyroid hormones** from the thyroid gland, stabilizing the patient's thyroid function. *Propylthiouracil* - **Propylthiouracil (PTU)** is an **antithyroid drug** that prevents the synthesis of thyroid hormones by inhibiting the organification of iodine and the coupling of iodotyrosines. - Although it helps to achieve a **euthyroid state** before surgery, it does not directly reduce the vascularity of the thyroid gland to decrease intraoperative bleeding. *Betamethasone* - **Betamethasone** is a corticosteroid used for its **anti-inflammatory** and immunosuppressive effects. - It is not typically used preoperatively in Graves' disease to reduce thyroid vascularity or bleeding; its primary role might be in managing severe **ophthalmopathy** or thyroid storm, not surgical bleeding. *Propranolol* - **Propranolol** is a **beta-blocker** used to control the adrenergic symptoms of hyperthyroidism, such as **tachycardia**, palpitations, and tremors. - While it helps to achieve a more stable cardiac state for surgery, it does not directly impact the **vascularity** of the thyroid gland or reduce surgical bleeding.
