Cardiovascular Disease Prevention Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Cardiovascular Disease Prevention. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Cardiovascular Disease Prevention Indian Medical PG Question 1: Among the following, most reliable test for screening of diabetes mellitus?
- A. Urine sugar
- B. Random sugar
- C. Fasting sugar (Correct Answer)
- D. Glucose tolerance test
Cardiovascular Disease Prevention Explanation: ***Fasting sugar***
- A **fasting plasma glucose** (FPG) test is the most common and reliable initial test for screening for **diabetes mellitus** because it measures blood glucose after an overnight fast (typically 8-12 hours), providing a baseline level unaffected by recent food intake [1].
- A fasting glucose level of **≥ 126 mg/dL** (7.0 mmol/L) on two separate occasions is diagnostic of diabetes, making it an excellent screening tool for identifying individuals with impaired glucose metabolism [1].
*Random sugar*
- A random plasma glucose test can be used to diagnose diabetes if the level is **≥ 200 mg/dL** (11.1 mmol/L) in a symptomatic individual, but it is less reliable for screening asymptomatic individuals due to its variability depending on recent food intake [1].
- Because it can be measured at any time of day without regard to the last meal, it has a **lower sensitivity** for detecting early stages of diabetes compared to fasting glucose.
*Glucose tolerance test*
- An **oral glucose tolerance test** (OGTT) is highly sensitive and specific for diagnosing diabetes and impaired glucose tolerance, but it is more cumbersome and time-consuming, involving multiple blood draws over two hours after consuming a sugary drink.
- While it is a definitive diagnostic test, its complexity makes it **less practical for routine screening** in large populations compared to simpler tests like fasting plasma glucose.
*Urine sugar*
- The presence of glucose in urine (glycosuria) indicates that blood glucose levels have exceeded the **renal threshold** (typically around 180 mg/dL), meaning the kidneys are unable to reabsorb all the glucose.
- This is a **less sensitive and specific** method for screening, as it only becomes positive once blood glucose is significantly elevated, and it does not detect milder forms of impaired glucose metabolism or early diabetes.
Cardiovascular Disease Prevention Indian Medical PG Question 2: Which of the following is a non- modifiable risk factor for CHD -
- A. Diabetes
- B. Smoking
- C. Hypertension
- D. Old age (Correct Answer)
Cardiovascular Disease Prevention Explanation: Old age
- Age is a **non-modifiable risk factor** for Coronary Heart Disease (CHD) because it is an inherent biological process that cannot be changed [3].
- The risk of developing CHD **increases with age** due to cumulative exposure to other risk factors and natural wear and tear on the cardiovascular system [3].
*Diabetes*
- Diabetes is a **modifiable risk factor** for CHD because it can be managed and controlled through lifestyle changes, medication, and regular monitoring [2].
- **Poorly controlled diabetes** significantly increases the risk of heart disease by damaging blood vessels and promoting atherosclerosis.
*Smoking*
- Smoking is a highly **modifiable risk factor** for CHD as it can be completely stopped [1], [2].
- **Cessation of smoking** significantly reduces the risk of heart attack and stroke over time [1].
*Hypertension*
- Hypertension is a **modifiable risk factor** for CHD because blood pressure can be lowered through lifestyle interventions, such as diet and exercise, and pharmacotherapy [2].
- **Uncontrolled high blood pressure** places increased stress on the heart and blood vessels, accelerating the development of atherosclerosis [1].
Cardiovascular Disease Prevention Indian Medical PG Question 3: On republic day, a camp was organized and people were screened for Hypertension by checking BP and for diabetes by checking their BMI and Blood sugar level, which level of prevention is this?
- A. Secondary (Correct Answer)
- B. Tertiary
- C. Primary
- D. Primordial
Cardiovascular Disease Prevention Explanation: ***Secondary***
- This level of prevention focuses on **early detection** and prompt treatment of a disease to halt or slow its progression.
- **Screening for hypertension and diabetes** through BP checks, BMI, and blood sugar levels aims to identify these conditions in their early stages before overt symptoms appear.
*Tertiary*
- This level of prevention involves measures to **reduce the impact** of an established disease, prevent complications, and improve quality of life.
- Examples include rehabilitation programs or medications for long-term disease management, which are not described in the scenario.
*Primary*
- This level of prevention aims to **prevent a disease from occurring** in the first place, typically by addressing risk factors.
- Examples include vaccination, health education on healthy eating, or promoting physical activity to prevent the development of hypertension or diabetes.
*Primordial*
- This is the **earliest level of prevention**, targeting the underlying social, environmental, and economic conditions that contribute to risk factors for disease.
- It involves interventions to *prevent the emergence of risk factors* in populations, such as broad public health policies or community-wide initiatives.
Cardiovascular Disease Prevention Indian Medical PG Question 4: In community health programs, a population of 1000 is typically covered by which healthcare worker?
- A. ASHA worker (Correct Answer)
- B. ANM (Auxiliary Nurse Midwife)
- C. AWW (Anganwadi Worker)
- D. Trained dai
Cardiovascular Disease Prevention Explanation: ***ASHA worker***
- An **ASHA (Accredited Social Health Activist) worker** is the primary community health worker who covers a population of **1,000** in community health programs.
- Under the **National Health Mission (NHM)**, one ASHA is appointed for every **1,000 population** in rural areas or per village.
- Their roles include facilitating access to health services, health awareness, promoting institutional deliveries, immunization, and serving as a bridge between the community and the public health system.
*Trained dai*
- **Trained dais (Traditional Birth Attendants)** were historically used but this program has been largely discontinued.
- The focus has shifted from home deliveries by dais to **institutional deliveries** assisted by skilled birth attendants.
- While they may have covered populations in the past, they are not part of the current structured community health workforce.
*ANM (Auxiliary Nurse Midwife)*
- An **ANM** serves a **much larger population** of approximately **5,000** at the sub-center level.
- They provide primary health services including maternal and child health, family planning, immunization, and basic curative care.
- One ANM is typically posted at each sub-center.
*AWW (Anganwadi Worker)*
- An **AWW** covers a **smaller population** of approximately **400-800 in rural areas** and up to **1,000 in urban/tribal areas**.
- They primarily focus on **early childhood care and development** through Anganwadi centers under the ICDS scheme.
- Their functions include supplementary nutrition, preschool education, and health and nutrition education for women and children.
Cardiovascular Disease Prevention Indian Medical PG Question 5: Which of the following is the LEAST important step in the national TB control program?
- A. Treatment of sputum positive cases
- B. BCG vaccination (Correct Answer)
- C. Isolation of sputum positive cases
- D. Treatment of contacts
Cardiovascular Disease Prevention Explanation: ***BCG vaccination***
- While BCG vaccination offers some protection against severe forms of TB, particularly in children, it has **limited efficacy** against adult pulmonary TB, which is the primary driver of transmission.
- The national TB control program's main focus is on **interrupting transmission** by identifying and effectively treating infectious cases.
*Treatment of sputum positive cases*
- This is a cornerstone of TB control because **sputum-positive cases** are the primary source of airborne transmission.
- Effective treatment rapidly renders patients **non-infectious**, preventing further spread of the disease within the community.
*Isolation of sputum positive cases*
- **Isolation** of highly infectious individuals helps to prevent the immediate spread of *Mycobacterium tuberculosis* to others in close contact.
- This is a crucial **infection control measure**, especially in healthcare settings and within households.
*Treatment of contacts*
- Treating contacts, especially those with **latent TB infection (LTBI)** or who are at high risk of progression to active disease (e.g., immunocompromised individuals), is vital for preventing the development of new active cases.
- This strategy targets the **prevention of future active disease** in individuals already exposed to the bacterium.
Cardiovascular Disease Prevention Indian Medical PG Question 6: What is the primary method of primordial prevention for Coronary Artery Disease (CAD)?
- A. Lifestyle change (Correct Answer)
- B. Coronary bypass
- C. Treatment of CAD
- D. Screening for hypertension
Cardiovascular Disease Prevention Explanation: ***Lifestyle change***
- **Primordial prevention** aims to prevent the development of risk factors themselves, which is best achieved through promoting healthy behaviors like diet, exercise, and avoiding tobacco at the population level.
- This approach acts *before* the onset of risk factors, addressing societal and environmental determinants of health.
- Examples include promoting healthy eating habits in schools, creating walkable communities, and tobacco-free environments.
*Coronary bypass*
- **Coronary bypass surgery** is a treatment for established CAD with significant blockages, not a preventive measure.
- It falls under the category of **tertiary prevention**, aiming to reduce complications and improve quality of life in existing disease.
*Treatment of CAD*
- **Treating CAD** (e.g., medications like statins or antiplatelets, procedures like angioplasty) is a form of **secondary** or **tertiary prevention**.
- It focuses on managing existing disease or preventing its progression, rather than preventing the initial development of risk factors.
*Screening for hypertension*
- **Screening** is a form of **secondary prevention** aimed at early detection of risk factors or disease.
- While important, it occurs *after* risk factors have already developed, unlike primordial prevention which prevents risk factors from emerging.
Cardiovascular Disease Prevention Indian Medical PG Question 7: What is the primary health concern addressed by the Rashtriya Bal Swasthya Karyakram (RBSK)?
- A. Adult chronic diseases
- B. Elderly health
- C. Non-communicable diseases in the youth
- D. Comprehensive healthcare for children from birth to 18 years (Correct Answer)
Cardiovascular Disease Prevention Explanation: **Comprehensive healthcare for children from birth to 18 years**
- The **Rashtriya Bal Swasthya Karyakram (RBSK)** is a national program explicitly designed to provide comprehensive health screening and early intervention for 0-18 year-olds
- Its focus is on detecting and managing the **4 D's**: Defects at birth, Deficiencies, Diseases, and Developmental delays
- The program provides regular health check-ups, early detection of health conditions, referral for treatment, and promotes healthy development across this critical age group
*Adult chronic diseases*
- While public health initiatives address adult chronic diseases, they are not the primary focus of the **RBSK** program, which targets a younger demographic
- Programs like the **National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases & Stroke (NPCDCS)** are more aligned with adult chronic disease management
*Elderly health*
- **RBSK** is specifically focused on the health of children and adolescents, not the elderly population
- **National Programme for Healthcare of the Elderly (NPHCE)** is a dedicated initiative for elderly health
*Non-communicable diseases in the youth*
- While **RBSK** does address some non-communicable diseases (NCDs) through early detection and management, its scope is much broader, encompassing all 4 D's
- RBSK aims for **holistic child health** rather than exclusively targeting NCDs in youth, which is a subset of its overall mandate
Cardiovascular Disease Prevention Indian Medical PG Question 8: True about Cardiovascular disease (CVD)
- A. Coronary heart disease causes 25% of total deaths
- B. Urban and rural areas have equal incidence
- C. Primordial prevention is best strategy (Correct Answer)
- D. RHD is the most common cause of CVD
Cardiovascular Disease Prevention Explanation: ***Primordial prevention is best strategy***
- **Primordial prevention** aims to prevent the development of risk factors for CVD in the first place, often starting in childhood.
- This strategy targets entire populations with public health initiatives to promote healthy lifestyles and environments, making it the most effective long-term approach to reduce CVD burden.
*Coronary heart disease causes 25% of total deaths*
- **Coronary heart disease (CHD)** accounts for approximately 16-17% of all deaths globally, not 25%.
- While CHD is a leading cause of death, stating it causes 25% of total deaths is an overestimation.
*RHD is the most common cause of CVD*
- **Rheumatic Heart Disease (RHD)** is an important cause of cardiovascular disease in developing countries including India.
- However, **ischemic heart disease** (coronary artery disease) and **hypertension** are the most common causes of CVD globally and in India, not RHD.
*Urban and rural areas have equal incidence*
- The incidence of cardiovascular disease differs significantly between **urban and rural areas**.
- Urban areas typically have higher CVD incidence due to lifestyle factors (sedentary behavior, unhealthy diet, stress), though rural rates are increasing due to epidemiological transition.
Cardiovascular Disease Prevention Indian Medical PG Question 9: Which of the following is primordial prevention for non-communicable diseases?
- A. Salt restriction in high NCD area
- B. Smoking cessation in high NCD area
- C. Preservation of traditional diet in low NCD area (Correct Answer)
- D. Early diagnosis & Treatment
Cardiovascular Disease Prevention Explanation: ***Preservation of traditional diet in low NCD area***
- **Primordial prevention** targets the underlying causes of disease before risk factors are established, often at a population level.
- Preserving a **healthy traditional diet** in an area with low rates of non-communicable diseases (NCDs) prevents the emergence of shared risk factors like processed food consumption and sedentary lifestyles.
*Salt restriction in high NCD area*
- This is an example of **primary prevention**, as it aims to reduce a specific risk factor (high salt intake) in a population susceptible to NCDs like hypertension.
- It intervenes when risk factors are already present or emerging, unlike primordial prevention which aims to prevent their development.
*Smoking cessation in high NCD area*
- Also a form of **primary prevention**, as it targets an existing modifiable risk factor (smoking) to prevent the onset of NCDs.
- It focuses on individuals or groups already exposed to a risk factor rather than preventing the societal conditions that lead to its emergence.
*Early diagnosis & Treatment*
- This falls under **secondary prevention**, which aims to detect and treat diseases early to halt their progression and prevent complications.
- It occurs after the disease has already begun but before significant symptoms or irreversible damage have occurred.
Cardiovascular Disease Prevention Indian Medical PG Question 10: The preferred public health approach to control non-communicable disease is -
- A. Focus on high risk individuals for reduction of risk
- B. Early diagnosis and treatment of identified cases
- C. Shift to the population-based approach (Correct Answer)
- D. Individual disease-based vertical programs
Cardiovascular Disease Prevention Explanation: ***Shift to the population-based approach***
- A **population-based approach** aims to reduce the average risk across the entire population, leading to a larger overall reduction in NCD burden.
- This strategy focuses on broad interventions like health promotion, policy changes, and environmental modifications that benefit everyone.
*Focus on high risk individuals for reduction of risk*
- This approach, while important, only targets a smaller subset of the population and may miss individuals who are at moderate risk but contribute significantly to the overall disease burden.
- It relies on identifying and intervening with specific individuals, which can be resource-intensive and may not achieve widespread impact.
*Early diagnosis and treatment of identified cases*
- This is a crucial component of secondary prevention but primarily addresses **existing disease** rather than preventing its occurrence in the first place across the population.
- While it improves outcomes for affected individuals, it does not tackle the root causes of NCDs at a population level.
*Individual disease-based vertical programs*
- **Vertical programs** are highly focused on a single disease, which can lead to fragmentation of services and inefficient use of resources.
- They often fail to address the common risk factors and determinants that contribute to multiple NCDs, hindering a holistic public health response.
