Global Health Technology Solutions Indian Medical PG Practice Questions and MCQs
Question 1: Which intervention has shown the highest return on investment in national STI control programs?
- A. Mobile testing units
- B. Online partner notification
- C. Integration with HIV services (Correct Answer)
- D. Mass media campaigns
Explanation: ***Integration with HIV services*** - This approach offers the **highest return on investment** for national STI control programs as it leverages existing infrastructure and funding for HIV services, maximizing resource utilization. - **Syndromic management of STIs integrated with HIV care** allows for efficient screening, diagnosis, and treatment of both conditions simultaneously, reaching high-risk populations effectively. - **India's National AIDS Control Programme (NACP)** successfully demonstrates this model, with STI/RTI services integrated into HIV testing and counseling centers, reducing duplication and operational costs. - **WHO guidelines strongly recommend** this integration strategy as the most cost-effective approach for national STI control programs, particularly in resource-limited settings. *Mobile testing units* - While helpful for reaching underserved populations, **mobile units have high operational costs** including staffing, vehicle maintenance, and equipment, which significantly limit their overall return on investment. - Their effectiveness is often localized and may not provide broad, sustainable impact across an entire national program compared to integrated services. *Online partner notification* - This method's reach is limited by **digital literacy and access barriers**, potentially excluding high-risk groups without internet access, particularly relevant in the Indian context. - While it can improve partner tracing in certain populations, the initial setup costs and limited universal applicability reduce its overall cost-effectiveness compared to integrated clinical services. *Mass media campaigns* - These campaigns require **significant financial investment** for broadcast time and creative development, with outcomes that are difficult to quantify in terms of direct STI reduction. - While effective for raising general awareness, they generate less measurable return on investment for direct STI control services compared to targeted clinical interventions like integrated service delivery.
Question 2: A resource-limited setting shows high rates of congenital syphilis despite antenatal screening programs. Lab records show stock-outs and delayed results. Which integrated approach is most cost-effective?
- A. Implementation of point-of-care testing with same-day treatment (Correct Answer)
- B. Enhanced partner notification only
- C. Universal prophylactic treatment
- D. Increased lab capacity with result tracking system
Explanation: ***Implementation of point-of-care testing with same-day treatment*** - This approach directly addresses **stock-outs** and **delayed results** by providing immediate diagnosis and treatment, significantly reducing the window for mother-to-child transmission. - **Point-of-care testing (POCT)** eliminates the need for complex lab infrastructure and transport, making it highly cost-effective and efficient in resource-limited settings. *Enhanced partner notification only* - While important for controlling syphilis spread, **partner notification alone** does not solve the fundamental issues of delayed diagnosis and treatment for the pregnant woman. - It would not prevent congenital syphilis in cases where the mother's infection is already established and untreated due to diagnostic delays. *Universal prophylactic treatment* - Administering **universal prophylactic treatment** without a confirmed diagnosis is not cost-effective due to unnecessary drug use, potential for antibiotic resistance, and wastage of resources. - It would also not address the underlying systemic issues of screening program failures, only providing a broad, untargeted intervention. *Increased lab capacity with result tracking system* - This option addresses **delayed results** and **stock-outs** but requires significant financial investment in infrastructure, equipment, and personnel, which may not be feasible or as rapid in implementation as POCT. - Even with increased capacity, transport of samples and results can still introduce delays, and the cost-benefit might be lower compared to immediate POCT.
Question 3: The web-based IT system for case-based surveillance under National Tuberculosis Elimination Programme (NTEP, formerly RNTCP) is
- A. NIKSHAY (Correct Answer)
- B. E-TB Tracker
- C. SURAKSHA
- D. SAFETY-NET
Explanation: ***NIKSHAY*** - **NIKSHAY** is the official web-based IT system used by the National Tuberculosis Elimination Programme (NTEP, formerly RNTCP) in India for **case-based surveillance** and monitoring of TB cases. - Launched in 2012, it facilitates **real-time data entry**, tracking of patient outcomes, drug logistics management, and program monitoring, significantly improving the efficiency of TB control efforts. - It enables **notification of all TB cases**, both from public and private sectors, ensuring comprehensive surveillance. *E-TB Tracker* - **E-TB Tracker** is not the designated IT system for TB surveillance under NTEP in India. - This term may refer to other electronic tracking systems used in different contexts, but NIKSHAY remains the official platform for India's TB programme. *SURAKSHA* - **SURAKSHA** means safety or protection in Hindi and is not associated with any specific web-based IT system for TB surveillance under NTEP. - This is not a recognized TB surveillance platform in the Indian context. *SAFETY-NET* - **SAFETY-NET** is a generic term referring to social protection programs or health support systems. - There is no specific NTEP initiative for TB surveillance identified by this name.
Question 4: The commonly used theory to predict individual's behaviour regarding preventive health care is:
- A. Salutogenic model
- B. Transtheoretical model
- C. Social cognitive theory
- D. Health belief model (Correct Answer)
Explanation: ***Health belief model*** - This model is widely used for **predicting preventative health behaviors**, as it focuses on an individual's perceptions of threat and benefits. - It considers factors like **perceived susceptibility, perceived severity, perceived benefits, perceived barriers**, cues to action, and self-efficacy in motivating health actions. *Salutogenic model* - The salutogenic model emphasizes factors that **promote health and well-being**, rather than focusing on disease or risk factors. - It centers around an individual's **sense of coherence**, which is their capacity to comprehend, manage, and find meaning in life's challenges. *Transtheoretical model* - This model describes **stages of change** that individuals go through when modifying a health behavior, such as precontemplation, contemplation, preparation, action, and maintenance. - While useful for understanding behavior change, it is more about the **process of change** rather than predicting initial engagement in preventative care. *Social cognitive theory* - Social cognitive theory emphasizes the role of **observational learning, social experiences, and self-efficacy** in the development of personality and health behaviors. - While it explains how individuals learn and perform health actions, it is not as directly focused on the **cognitive factors influencing preventative care decisions** as the Health Belief Model.
Question 5: Which of the following is NOT a side effect of digitalis?
- A. Nausea and vomiting
- B. Ventricular Bigeminy
- C. Vasodilatation (Correct Answer)
- D. Ventricular tachycardia
Explanation: **Vasodilatation** - **Digitalis**, primarily digoxin, is known for its **positive inotropic effect**, increasing myocardial contractility, and for its **vasoconstrictive properties** at higher doses due to sympathetic activation and direct smooth muscle effects, not vasodilatation. - While it can indirectly improve cardiac output and thus tissue perfusion, its direct vascular effects do not typically include widespread vasodilatation. *Ventricular tachycardia* - **Digitalis toxicity** can lead to various arrhythmias, including **ventricular tachycardia**, which is a potentially life-threatening side effect. - This occurs due to increased automaticity and delayed afterdepolarizations in ventricular myocytes. *Nausea and vomiting* - **Gastrointestinal symptoms** such as **nausea and vomiting** are common early signs of digitalis toxicity. - These effects are thought to be mediated by the drug's action on the chemoreceptor trigger zone in the brainstem. *Ventricular Bigeminy* - **Ventricular bigeminy**, characterized by alternating normal and premature ventricular beats, is another classic manifestation of **digitalis toxicity**. - This arrhythmia results from enhanced automaticity and altered conduction properties in the ventricles.
Question 6: According to Sustainable Development Goal 3 (SDG 3) - 'Ensure healthy lives and promote well-being for all at all ages', what is the target for reducing the global maternal mortality ratio by 2030?
- A. 100
- B. 50
- C. 70 (Correct Answer)
- D. 90
Explanation: ***70*** - SDG 3 aims to reduce the **global maternal mortality ratio** to less than **70 per 100,000 live births** by 2030. - This target emphasizes improving maternal health outcomes worldwide and preventing deaths related to pregnancy and childbirth. *100* - While a reduction is sought, a target of 100 per 100,000 live births is **not ambitious enough** to meet the specific goal set by SDG 3. - The established global target is lower, reflecting a greater commitment to maternal health. *50* - A target of 50 per 100,000 live births would be **more ambitious** than the SDG 3 goal. - While desirable, it is not the specific, agreed-upon target for the global average under SDG 3. *90* - A target of 90 per 100,000 live births is **higher** than the established SDG 3 goal. - This value does not align with the specific global maternal mortality ratio target set for 2030.
Question 7: Based on the provided image, which of the following is the correct diagnosis?
- A. Uterus didelphys
- B. Bicornuate Uterus
- C. Unicornuate Uterus (Correct Answer)
- D. Septate uterus
Explanation: ***Unicornuate Uterus*** - The image distinctly shows **only one fallopian tube and one rudimentary uterine horn** on the right side, indicating a unicornuate uterus. - This malformation results from the **incomplete development of one Müllerian duct**, leading to a single, banana-shaped uterine cavity. *Uterus didelphys* - This condition involves **two completely separate uteri**, each with its own cervix and vagina. - The image does not show evidence of two distinct uterine bodies or cervices. *Bicornuate Uterus* - A bicornuate uterus is characterized by **two uterine horns that fuse caudally**, creating a heart-shaped appearance with a shared cervix. - The image clearly lacks the characteristic heart shape and shows only one functional horn. *Septate uterus* - A septate uterus has a **fibrous or muscular septum** dividing the uterine cavity, while the external uterine contour remains normal. - The image does not show a septum or a normal external uterine contour with an internal division; instead, it presents with a single underdeveloped horn.
Question 8: In a village, despite health education for oral cancer, people don't follow instructions even after referral. Despite persuasive reminders, people are still reluctant. This best fits under which model:
- A. Health belief model
- B. Public health model
- C. Social compliance
- D. Trans-theoretical model (Correct Answer)
Explanation: ***Trans-theoretical model*** - This model emphasizes that individuals move through distinct stages (precontemplation, contemplation, preparation, action, maintenance) when adopting a new behavior. The villagers' reluctance to follow instructions, despite education and reminders, suggests they are likely in the **precontemplation** or **contemplation** stages, where they are either unaware of the problem or are not yet ready to take action. - The model accounts for the **difficulty in behavior change** even with external efforts, as readiness to change is internal and stages are progressive. *Health belief model* - This model focuses on an individual's perception of the **threat of a health problem** and the **pros and cons of taking action**. While education might address perceived susceptibility and severity, the model doesn't fully explain why people remain reluctant even after persuasive reminders, suggesting other factors beyond belief are at play. - It primarily explains *why* individuals might *consider* changing their behavior but not necessarily *how* they progress through the actual change process. *Public health model* - The public health model is a broad framework used to understand and address health issues at a population level, often focusing on **prevention, promotion, and interventions**. While addressing oral cancer in a village fits within this model's scope, it doesn't specifically explain the *individual psychological barriers* to behavioral change, like reluctance despite education and reminders. - This model is more about **strategies and policies** for population health rather than individual behavior change. *Social compliance* - Social compliance refers to individuals conforming to rules or requests from authority figures or social norms. The scenario explicitly states that despite "persuasive reminders," people are "reluctant," indicating a **lack of compliance** rather than an explanation for the behavior itself. - This term describes the *outcome* of behavior in a social context, not the *underlying psychological process* of behavior change over time.
Question 9: Which statement best describes the concept of web of causation in disease?
- A. Applicable primarily to common diseases.
- B. Focuses on epidemiological ratios.
- C. Aids in interrupting the transmission of diseases.
- D. Considers all relevant factors associated with disease causation. (Correct Answer)
Explanation: ***Considers all relevant factors associated with disease causation.*** - The **web of causation** model acknowledges that diseases often arise from a complex interplay of multiple interconnected factors, rather than a single cause. - It emphasizes that **no single factor is sufficient or necessary** for disease occurrence, but rather a combination of factors increases susceptibility or triggers the disease process. *Applicable primarily to common diseases.* - The web of causation model is a **universal concept** in epidemiology, applicable to both common and rare diseases. - Its utility lies in explaining the complex etiology of diseases regardless of their prevalence. *Focuses on epidemiological ratios.* - While epidemiological ratios (e.g., odds ratios, relative risk) measure associations between factors and disease, the **web of causation** provides a conceptual framework for understanding the *nature* of these associations. - It describes the **interconnections and causal pathways**, not just the statistical strength of association. *Aids in interrupting the transmission of diseases.* - This statement is more descriptive of **public health interventions** based on understanding disease transmission dynamics. - While insights from the **web of causation** can inform interventions, the model itself describes the *etiology* rather than directly outlining methods for interrupting transmission.
Question 10: Improving Quality of Labour room is covered under which program?
- A. Ayushman Bharat Scheme
- B. LaQshya (Correct Answer)
- C. JSSK
- D. Improving care of newborn
Explanation: ***LaQshya*** - **LaQshya (Labour Room Quality Improvement Initiative)** is specifically designed to improve the quality of care in labour rooms and maternity OTs. - Its goal is to reduce preventable maternal and newborn mortality, morbidity, and stillbirths associated with childbirth by implementing **quality improvement interventions**. *Ayushman Bharat Scheme* - This is a national health protection scheme aimed at providing **health insurance coverage** and access to comprehensive primary healthcare services. - While it aims to improve overall health outcomes, it is not a direct program focused solely on **labour room quality improvement**. *JSSK* - **Janani Shishu Suraksha Karyakram (JSSK)** provides **cashless services** to pregnant women and sick infants in public health institutions. - Its focus is on providing financial protection and free services, not on the specific **quality improvement of the physical labour room infrastructure or processes**. *Improving care of newborn* - This is a general objective or a component of broader maternal and child health programs. - It does not refer to a specific, named program focused on **labour room quality improvement** in the way LaQshya does.
