Question 131: India is a country with different cultures and diverse languages. Which steps should a physician take to address the patient for better outcomes? 1. Insist on good communication 2. Insist on communication only via an interpreter 3. Treat them regardless of their cultural perceptions 4. The physician should consider the patient's religion and cultural perception Select the correct combination:
- A. 1,4 (Correct Answer)
- B. 1,2
- C. 2,3
- D. 3,4
Explanation: ***1,4*** - **Good communication** is paramount in healthcare, especially in a diverse country like India, to ensure **patient understanding**, **adherence** to treatment plans, and overall patient satisfaction. - Considering a patient's **religion and cultural perceptions** allows the physician to tailor treatment and communication in a sensitive and **respectful manner**, fostering trust and better **health outcomes**. *1,2* - While good communication (1) is vital, **insisting solely on an interpreter** (2) may not always be feasible or necessary, particularly if the physician and patient share a common language or if the patient prefers direct communication. This can also disrupt the flow of rapport building. - **Over-reliance on interpreters** can sometimes lead to misinterpretations or loss of non-verbal cues if the interpreter is not trained in medical interpretation. *2,3* - **Insisting only on an interpreter** (2) can be restrictive and may compromise direct patient-physician rapport, as discussed above. - **Treating patients regardless of their cultural perceptions** (3) is an ethnocentric approach that can lead to mistrust, non-adherence, and ultimately **poor health outcomes** as it disregards the patient's beliefs and values regarding health and illness. *3,4* - **Treating patients regardless of their cultural perceptions** (3) can result in a lack of understanding and non-adherence if the treatment conflicts with the patient's deeply held beliefs. - While considering religion and cultural perception (4) is crucial, this option includes an incorrect approach (3) that can undermine patient care.
Question 132: Recommended HPV vaccination schedule for 9 to 14-year-olds according to WHO SAGE guidelines is:
- A. 1 or 2 doses (Correct Answer)
- B. 3 doses
- C. 3 or 4 doses
- D. 4 doses
Explanation: ***1 or 2 doses*** - The **WHO Strategic Advisory Group of Experts (SAGE)** on Immunization recommends a simplified **one- or two-dose schedule** for girls and boys aged 9–14 years. - This recommendation, updated in April 2022, is based on evidence demonstrating comparable efficacy of **single-dose HPV vaccination** to multi-dose regimens in this age group, while improving accessibility and uptake. - **Key advantage**: Reduced doses improve vaccination completion rates and reduce programmatic costs without compromising protection. *3 doses* - A **three-dose schedule** (0, 1-2, 6 months) was the original recommendation but is **no longer recommended** for the 9–14 age group. - Three doses are now reserved for **immunocompromised individuals** or those starting vaccination at older ages in some guidelines. - Maintaining a three-dose schedule would increase costs and reduce completion rates unnecessarily. *3 or 4 doses* - **Four doses** have never been part of any WHO HPV vaccination recommendation. - This option represents an excessive and unsupported schedule that would create unnecessary barriers to vaccination coverage. *4 doses* - **Four doses** are not recommended by WHO SAGE for any age group or clinical scenario. - This would represent over-vaccination without evidence of additional benefit and would significantly impair program implementation.
Question 133: Which of the following is a true statement about screening tests for genetic diseases?
- A. Screening test has better accuracy than diagnostic test
- B. It is always invasive
- C. It defines risk of transmission of disease to the child (Correct Answer)
- D. Screening requires genetic mapping
Explanation: ***Correct: It defines risk of transmission of disease to the child*** - Genetic screening aims to identify individuals or couples at risk of passing on **heritable genetic conditions** to their offspring. - This information helps in **family planning** and provides prenatal diagnostic options if the risk is high. - This is the **primary purpose** of genetic screening programs. *Incorrect: Screening test has better accuracy than diagnostic test* - **Screening tests** are designed to be broad and detect potential risks, often with lower specificity and sensitivity than diagnostic tests. - **Diagnostic tests** are typically more accurate and definitive, confirming the presence or absence of a disease after a positive screening result. *Incorrect: It is always invasive* - Many genetic screening tests, such as **non-invasive prenatal screening (NIPS)** from maternal blood or carrier screening via saliva, are non-invasive or minimally invasive. - While some diagnostic tests like **amniocentesis** or **chorionic villus sampling** are invasive, screening itself is not universally so. *Incorrect: Screening requires genetic mapping* - **Genetic mapping** refers to determining the relative positions of genes on a chromosome, which is a research tool for understanding genome organization. - Genetic screening primarily involves testing for specific mutations or chromosomal abnormalities, not creating a comprehensive genetic map of an individual.
Question 134: Which of the following is the true statement regarding measures to prevent typhoid transmission in the community?
- A. Typhoid vaccine administration is the best method of preventing transmission.
- B. Person-to-person transmission is the primary mode of spread.
- C. Drug resistance in typhoid is not as big a problem as in TB.
- D. Hygiene practice and clean sanitation control are more important than the typhoid vaccine. (Correct Answer)
Explanation: ***Hygiene practice and clean sanitation control is more important than the typhoid vaccine.*** - **Improved sanitation**, safe water supplies, and adequate hygiene practices are fundamental in controlling the spread of **typhoid fever**, as the disease is primarily transmitted through the **oral-fecal route**. - While vaccines are an important tool, they offer only partial protection and must be combined with **robust public health infrastructure** and **sanitation measures** for effective prevention. *Typhoid vaccine administration is the best method of preventing transmission.* - Typhoid vaccines offer protection, but their effectiveness is not 100%, and they typically require **booster doses** - **Vaccination campaigns** are most effective when implemented alongside improvements in **water and sanitation infrastructure**, as vaccines alone cannot fully prevent transmission in areas with poor hygiene. *Person-to-person transmission is the primary mode of spread.* - While person-to-person transmission can occur, especially in settings with poor hygiene, the primary mode of spread for typhoid is through the **ingestion of food or water contaminated** with the feces of an infected person or carrier. - This emphasizes the crucial role of **water and food safety** rather than just focusing on direct person-to-person contact. *Drug resistance in typhoid is not as big a problem as in TB.* - **Antimicrobial resistance (AMR)** in typhoid fever, particularly to fluoroquinolones and extended-spectrum beta-lactamase (ESBL) producing strains, is a **significant and growing global health concern**, complicating treatment. - While TB also faces serious drug resistance issues, the escalating problem of **extensively drug-resistant (XDR)** and **multi-drug resistant (MDR)** typhoid strains makes it a substantial threat, impacting treatment options and increasing morbidity and mortality.
Question 135: A multivariate analysis was conducted to examine the relationship between risk of developing blindness and age. The results are shown in the table below. Which of the following is true?
- A. 60-69 y age group shows statistically significant association with blindness
- B. <50 y age group serves as the reference category
- C. >80 y age group has the strongest association with blindness risk (Correct Answer)
- D. 50-59 y age group has the highest odds ratio for blindness risk
Explanation: ***>80 y age group has the strongest association with blindness risk*** - The odds ratio for the **>80 years** age group is **2.1**, which is the highest among all age groups listed in the table, indicating the strongest association with blindness risk. - A higher odds ratio means a greater likelihood of the outcome (blindness) compared to the reference category. - All age groups shown have **p-values <0.001**, confirming statistical significance. *60-69 y age group shows statistically significant association with blindness* - While the 60-69 y age group has an odds ratio of **1.5** with **p<0.001**, indicating statistical significance, it does not have the strongest association compared to the **>80 y** age group (OR 2.1). - Statistical significance confirms the association is real, but effect size (OR) determines strength of association. *<50 y age group serves as the reference category* - The table shows an **Odds Ratio (OR) of 1.1** for the **<50 y** age group, indicating it is also being compared to a reference (which would have OR = 1.0). - The reference category is not explicitly shown in the table but would typically be an even younger age group or overall population baseline. *50-59 y age group has the highest odds ratio for blindness risk* - The odds ratio for the **50-59 y** age group is **1.2**, which is lower than the **>80 y** age group (OR 2.1), the **70-79 y** age group (OR 1.6), and the **60-69 y** age group (OR 1.5). - This statement is incorrect as the **>80 y** age group clearly has the highest odds ratio for blindness risk.

Question 131: A 37-year-old unmarried nulliparous woman, having regular intercourse, is on oral contraceptive pills. Her mother was diagnosed with carcinoma breast at 60 years of age, and her elder sister was diagnosed with carcinoma ovary at 40 years of age. What is the next line of management?
- A. Prophylactic surgery
- B. Stop taking oral contraceptive pills
- C. Routine mammography
- D. Genetic counseling and screening for BRCA (Correct Answer)
Explanation: ***Genetic counseling and screening for BRCA*** - The patient's family history is highly suggestive of a **hereditary breast and ovarian cancer (HBOC) syndrome**, specifically a BRCA gene mutation. - **Sister with ovarian cancer at age 40** is a major red flag—ovarian cancer at ≤50 years in a first-degree relative is a specific criterion for BRCA testing according to NCCN guidelines. - Additionally, the mother's breast cancer (even at 60) combined with the sister's early ovarian cancer creates a **two first-degree relatives with breast/ovarian cancer pattern** that further strengthens the indication for genetic testing. - **Genetic counseling** is essential to assess risk, discuss testing options, interpret results, and plan appropriate risk-reduction strategies. - BRCA1/2 mutations confer a **40-60% lifetime risk of ovarian cancer** and **70-80% lifetime risk of breast cancer**. *Prophylactic surgery* - **Risk-reducing bilateral salpingo-oophorectomy (RRSO)** and possibly bilateral mastectomy are important options for BRCA mutation carriers, but should only be considered **after** genetic counseling and confirmed identification of a pathogenic mutation. - Proceeding directly to surgery without genetic confirmation would be premature and potentially unnecessary. *Stop taking oral contraceptive pills* - **OCPs actually reduce ovarian cancer risk** by approximately 50% with long-term use, which is protective even in BRCA carriers. - While OCPs may have a minimal impact on breast cancer risk, the ovarian cancer risk reduction benefit generally outweighs this concern. - Stopping OCPs without further genetic risk assessment is not the appropriate next step. *Routine mammography* - Standard mammography screening is insufficient for high-risk individuals with likely BRCA mutations. - If BRCA mutation is confirmed, enhanced screening protocols are recommended: **annual MRI plus mammography starting at age 30**, or 10 years before the earliest breast cancer in the family. - The priority is genetic assessment first to determine if intensified screening is warranted.

INI-CET 2022 - Surgery INI-CET Practice Questions and MCQs
Question 131: All the following are true about acute cholecystitis, except
- A. Gall bladder thickness >3 mm on USG
- B. Murphy's sign positive
- C. Preferential visualization of gall bladder in HIDA scan (Correct Answer)
- D. Leukocytosis
Explanation: ***Preferential visualization of gall bladder in HIDA scan*** - In acute cholecystitis, the **cystic duct** becomes obstructed, preventing bile flow into the gallbladder. - A **HIDA scan** (hepatobiliary iminodiacetic acid scan) would show **non-visualization of the gallbladder** due to this obstruction, not preferential visualization. *Gall bladder thickness >3 mm on USG* - An **ultrasound (USG)** finding of gallbladder wall thickening **greater than 3 mm** is a common indicator of inflammation in acute cholecystitis. - This thickening is due to **edema** and inflammation of the gallbladder wall. *Murphy's sign positive* - A **positive Murphy's sign** involves tenderness and an inspiratory arrest upon palpation of the right upper quadrant, specifically over the gallbladder. - This clinical sign is a **classic indicator** of acute cholecystitis. *Leukocytosis* - **Leukocytosis**, an elevated white blood cell count, is a common systemic inflammatory response seen in acute cholecystitis. - It reflects the body's reaction to the **inflammation and possible infection** within the gallbladder.
Question 132: Which of the following is not a relative contraindication for breast conservative surgery?
- A. Multicentric disease
- B. Previous radiation to breast
- C. Large tumor size
- D. Small tumor size (<3cm) (Correct Answer)
Explanation: ***Small tumor size (<3cm)*** ✓ - A small tumor size is **NOT a contraindication** for breast-conserving surgery; it is actually a **favorable condition** and an indication for breast conservation. - Small tumors allow for complete tumor removal with good cosmetic outcomes and adequate margins. - This is the **correct answer** as it is the only option that is NOT a relative contraindication. *Multicentric disease* - **Multicentric disease** refers to the presence of multiple tumor foci in **different quadrants** of the breast, making complete surgical removal challenging with breast-conserving surgery. - This is a **relative contraindication** as it increases the risk of **positive margins** and local recurrence, making mastectomy often a more appropriate option. *Previous radiation to breast* - Prior radiation therapy to the breast is a **contraindication** (often considered absolute) for subsequent breast radiation, which is an essential component of breast-conserving therapy. - Re-irradiation carries a high risk of severe **skin and tissue toxicity**, making further breast conservation unfeasible. *Large tumor size* - A large tumor size is a **relative contraindication** as it can make it difficult to achieve **clear surgical margins** while maintaining an acceptable cosmetic result. - However, **neoadjuvant chemotherapy** may downstage large tumors to make them suitable for breast-conserving surgery. - Without tumor reduction, it often requires **mastectomy**.
Question 133: Which of the following is not a perineal approach for the condition shown in the image?
- A. Ripstein's procedure (Correct Answer)
- B. Delorme's procedure
- C. Altemeier's procedure
- D. Thiersch's procedure
Explanation: ***Ripstein's procedure*** - The Ripstein procedure is an **abdominal approach** used for performing a rectopexy to treat rectal prolapse, which is clearly visible in the image. - It involves **fixing the rectum to the sacrum** through an abdominal incision using a synthetic mesh sling. - This is the **only non-perineal approach** among the options listed. *Delorme's procedure* - This is a **perineal approach** for rectal prolapse. - Involves **mucosal stripping** and plication of the rectal muscle wall through the anus. - Suitable for patients unfit for abdominal surgery or with short segment prolapse. *Altemeier's procedure* - This is a **perineal rectosigmoidectomy** (perineal approach). - Involves **resection of the prolapsed rectum and sigmoid colon** through the perineum. - Often combined with levatoroplasty for better results. *Thiersch's procedure* - This is a **perineal encirclement procedure**. - Involves placing a **wire, suture, or synthetic material** around the anus to narrow the anal opening. - Simple perineal approach but has high recurrence rates; rarely used as definitive treatment.
Question 134: A 50-year-old alcoholic patient presents with a history of waxing and waning jaundice for the past 2 months. His CT examination reveals dilatation of the common bile duct and pancreatic duct. What is the most probable diagnosis in the patient?
- A. Common bile duct stone
- B. Head of the pancreas carcinoma
- C. Cholangiocarcinoma
- D. Periampullary carcinoma (Correct Answer)
Explanation: ***Periampullary carcinoma*** - **Waxing and waning jaundice** is the **most characteristic feature** of periampullary tumors, as the tumor may intermittently obstruct and then temporarily release the **ampulla of Vater** (due to tumor friability, inflammation, or necrosis allowing temporary drainage). - The combination of **dilated common bile duct (CBD)** and **pancreatic duct (double duct sign)** indicates obstruction at the level of the ampulla. - The **intermittent nature of jaundice** is the key distinguishing feature that makes periampullary carcinoma more likely than pancreatic head carcinoma in this case. *Head of the pancreas carcinoma* - A **carcinoma of the head of the pancreas** also causes the **double duct sign** and can present with obstructive jaundice. - However, pancreatic head tumors typically cause **progressive, persistent, and painless jaundice** rather than waxing and waning jaundice, as the tumor causes constant external compression of both ducts. - This is a close differential, but the **fluctuating jaundice** favors a periampullary lesion. *Common bile duct stone* - While a **CBD stone** can cause waxing and waning jaundice due to intermittent obstruction (stone moving in and out of ampulla), it is **less likely to cause isolated dilatation of both the pancreatic duct and CBD** (double duct sign). - Stones typically cause **biliary colic, cholangitis, or pancreatitis** rather than isolated double duct dilatation. - The **double duct sign** without inflammatory features points more strongly to malignancy at the ampulla. *Cholangiocarcinoma* - **Cholangiocarcinoma** can cause biliary obstruction and jaundice, but it typically arises within the bile ducts themselves (intrahepatic or hilar). - **Distal cholangiocarcinoma** near the ampulla can mimic periampullary carcinoma, but it is less common for it to cause the degree of **pancreatic duct dilatation** seen in the double duct sign. - Cholangiocarcinoma usually causes **progressive rather than fluctuating jaundice**.
