Geriatric Health Issues Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Geriatric Health Issues. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Geriatric Health Issues Indian Medical PG Question 1: Which of the following is a key distinguishing feature of delirium compared to dementia?
- A. Visual hallucinations
- B. Gradual memory loss
- C. Acute onset of confusion and disorientation (Correct Answer)
- D. Difficulty in recognizing familiar people
Geriatric Health Issues Explanation: ***Acute onset of confusion and disorientation***
- Delirium is characterized by a **sudden (acute) onset** of mental status changes, including fluctuations in attention, awareness, and cognition, often presenting as **confusion and disorientation**.
- Its symptoms typically develop over hours to days, contrasting sharply with the more chronic and insidious progression of dementia.
*Gradual memory loss*
- **Gradual memory loss** is a hallmark symptom of **dementia**, a neurocognitive disorder characterized by a progressive decline in cognitive function over months to years.
- While memory impairment can occur in delirium, its onset is rapid and associated with a fluctuating course, not a steady decline.
*Visual hallucinations*
- While visual hallucinations can occur in **delirium**, they are not its most unique distinguishing feature from **dementia**, as they can also be prominent in certain types of dementia, such as **Lewy body dementia**.
- The acute, fluctuating nature of **cognitive impairment** is a more defining characteristic of delirium.
*Difficulty in recognizing familiar people*
- **Prosopagnosia** or the inability to recognize familiar faces, is a symptom that can manifest in advanced stages of **dementia** due to widespread brain atrophy.
- While patients with delirium might appear confused or disoriented to the point of not recognizing familiar individuals, this is usually part of a global, acute cognitive impairment and not a primary, isolated deficit.
Geriatric Health Issues Indian Medical PG Question 2: Which of the following is not a criterion suggesting causality in non communicable diseases?
- A. Specificity of association
- B. Dose response relationship
- C. Strength of association
- D. Lack of temporal association (Correct Answer)
Geriatric Health Issues Explanation: ***Lack of temporal association***
- For an exposure to cause a non-communicable disease, the exposure must precede the disease onset; therefore, a **lack of temporal association** explicitly argues *against* causality.
- This criterion is a fundamental principle of causality, as the **cause must occur before the effect**.
*Specificity of association*
- This criterion suggests that a single exposure should lead to a single disease. However, in non-communicable diseases, a single risk factor may contribute to multiple diseases (e.g., smoking and lung cancer, heart disease, stroke), and a single disease can have **multiple causes**.
- While it was important in the original Bradford Hill criteria, its relevance is diminished in modern epidemiology due to the **multifactorial nature of chronic diseases**.
*Dose response relationship*
- This criterion implies that as the **amount or duration of exposure increases**, the **risk or severity of the disease also increases**.
- This is a strong indicator of causality because it suggests a biological gradient.
*Strength of association*
- A strong association, often measured by a **high relative risk or odds ratio**, increases the likelihood of a causal relationship.
- A weak association, while not ruling out causality, makes it less likely to be directly causal and more likely to be influenced by other factors or confounding variables.
Geriatric Health Issues Indian Medical PG Question 3: A Patient falls down often with behavioral change and enuresis. What is the condition associated with him?
- A. Normal pressure hydrocephalus (NPH) (Correct Answer)
- B. Parkinson's disease (PD)
- C. Alzheimer's disease (AD)
- D. Frontotemporal dementia (FTD)
Geriatric Health Issues Explanation: ***Normal pressure hydrocephalus (NPH)***
- NPH is characterized by the classic triad of symptoms: **gait disturbance** (leading to falls), **dementia/behavioral changes**, and **urinary incontinence** (enuresis) [1].
- These symptoms arise from the accumulation of cerebrospinal fluid (CSF) in the brain's ventricles without a corresponding increase in intracranial pressure [2].
*Parkinson's disease (PD)*
- While PD causes **gait instability** and falls, its primary symptoms include **bradykinesia**, **rigidity**, and **resting tremor**, which are not mentioned.
- Behavioral changes can occur later in the disease, but **enuresis** is not a hallmark symptom.
*Alzheimer's disease (AD)*
- AD primarily presents with **progressive memory loss** and cognitive decline, not gait disturbances or enuresis as early or prominent features.
- Falls usually occur much later due to advanced cognitive impairment and not as an initial triad component.
*Frontotemporal dementia (FTD)*
- FTD is characterized by early and prominent **behavioral and personality changes** or language difficulties.
- While falls can occur due to executive dysfunction, **gait disturbance** and **enuresis** as part of a triad are not typical presenting features.
Geriatric Health Issues Indian Medical PG Question 4: 65-year-old person with hearing loss with normal speech discrimination is suffering from?
- A. Noise induced hearing loss
- B. Presbycusis (Correct Answer)
- C. Ototoxic drug
- D. NOHL
Geriatric Health Issues Explanation: ***Presbycusis***
- **Presbycusis**, or age-related hearing loss, is characterized by a gradual, symmetrical, **sensorineural hearing loss** primarily affecting high frequencies.
- Importantly, **speech discrimination** is typically preserved in the early and moderate stages of presbycusis, which aligns with the normal speech discrimination in a 65-year-old.
*Noise induced hearing loss*
- **Noise-induced hearing loss** is caused by exposure to loud noise and often presents with a characteristic **4 kHz notch** in the audiogram.
- While it can cause sensorineural hearing loss, it's not exclusively defined by the age-related onset and might involve more significant **speech discrimination difficulties** depending on the severity and frequency range affected.
*Ototoxic drug*
- Hearing loss due to **ototoxic drugs** (e.g., aminoglycosides, cisplatin) typically manifests as a **bilateral, high-frequency sensorineural hearing loss** that can progress rapidly.
- The history of **drug exposure** would be a key differentiating factor, and while speech discrimination can be affected, the lack of other specific details makes this less likely without further information.
*NOHL*
- **NOHL** is not a standard, recognized medical acronym for a specific type of hearing loss.
- This option is likely a distractor and does not represent a known diagnosis fitting the described clinical picture.
Geriatric Health Issues Indian Medical PG Question 5: The Confusion Assessment Method (CAM) is used for which of the following?
- A. Schizophrenia
- B. Delirium (Correct Answer)
- C. Dementia
- D. Depression
Geriatric Health Issues Explanation: ***Delirium***
- The Confusion Assessment Method (CAM) is a widely used and highly sensitive and specific tool for the rapid identification of **delirium**.
- It assesses for acute onset and fluctuating course, inattention, disorganized thinking, and altered level of consciousness.
*Schizophrenia*
- Schizophrenia is a chronic mental health disorder primarily characterized by **psychosis**, including hallucinations, delusions, and disorganized thought.
- While patients with schizophrenia can experience cognitive difficulties, specialized scales like the Positive and Negative Syndrome Scale (PANSS) are used, not the CAM.
*Dementia*
- Dementia is a gradual and progressive decline in cognitive function, including memory, thinking, and reasoning, severe enough to interfere with daily life.
- Tools like the mini-mental state examination (MMSE) or Montreal Cognitive Assessment (MoCA) are used for screening and assessing dementia, not the CAM.
*Depression*
- Depression is a mood disorder characterized by persistent sadness, loss of interest, and other emotional and physical symptoms.
- Assessment tools like the Hamilton Depression Rating Scale (HDRS) or Patient Health Questionnaire-9 (PHQ-9) are used for depression.
Geriatric Health Issues Indian Medical PG Question 6: Which of the following statements about Alzheimer's disease is false?
- A. Alzheimer's disease is curable. (Correct Answer)
- B. Alzheimer’s disease causes dementia.
- C. Alzheimer’s disease is a leading cause of cognitive decline.
- D. One in 10 people age 65 and older has Alzheimer’s disease
Geriatric Health Issues Explanation: ***Alzheimer’s disease is curable***
- Alzheimer's disease is currently **incurable**, and treatments primarily focus on managing symptoms and slowing disease progression.
- Research is ongoing to find more effective treatments, but there is no known cure yet.
*Alzheimer’s disease is a leading cause of cognitive decline.*
- Alzheimer's disease is the **most common cause of dementia**, accounting for 60-80% of cases, making it a primary driver of cognitive decline in older adults.
- The disease progressively damages brain cells, leading to a decline in memory, thinking, and reasoning abilities.
*Alzheimer’s disease causes dementia.*
- **Dementia** is the clinical syndrome characterized by significant cognitive decline, and Alzheimer's disease is the most common underlying cause.
- The characteristic pathological changes in Alzheimer's (amyloid plaques and neurofibrillary tangles) lead to neuronal damage and the resulting dementia symptoms.
*One in 10 people age 65 and older has Alzheimer’s disease*
- This statement accurately reflects the prevalence of Alzheimer's disease, as approximately 11.3% of people aged 65 and older in the United States have Alzheimer's dementia.
- The risk of developing Alzheimer's disease **increases with age**, making it more common in the older population.
Geriatric Health Issues Indian Medical PG Question 7: Which of the following is TRUE about bone healing in elderly patients?
- A. Enhanced Angiogenesis
- B. Better Callus Formation
- C. Faster Healing Rate
- D. Delayed Union is More Common (Correct Answer)
Geriatric Health Issues Explanation: ***Delayed Union is More Common***
- **Aging** is associated with a decrease in the number and activity of **osteoblasts** and stem cells, leading to a slower bone remodeling process.
- Reduced **blood supply** to the fracture site and the presence of comorbidities in elderly patients contribute to delayed healing and an increased risk of complications like non-union.
*Enhanced Angiogenesis*
- **Angiogenesis**, the formation of new blood vessels, tends to be reduced in elderly patients due to age-related changes in growth factor production and endothelial cell function.
- A compromised blood supply to the fracture site negatively impacts the delivery of essential nutrients and cells required for bone repair.
*Better Callus Formation*
- **Callus formation**, a crucial step in secondary bone healing, is often impaired in elderly individuals.
- This impairment is due to decreased cellular activity, reduced growth factor production, and a less robust inflammatory response.
*Faster Healing Rate*
- Bone healing is generally **slower** in elderly patients compared to younger individuals.
- This diminished healing rate is attributed to a decline in osteogenic potential, reduced vascularity, and frequently, poorer overall health status.
Geriatric Health Issues Indian Medical PG Question 8: Which of the following is not a component of the Goldman Revised Cardiac Risk Index?
- A. History of preoperative treatment with insulin
- B. History of preoperative serum creatinine >2.0 mg/dL
- C. Age > 80 yrs (Correct Answer)
- D. History of ischemic heart disease
Geriatric Health Issues Explanation: ***Age > 80 yrs***
- **Age** is not a parameter included in the Goldman Revised Cardiac Risk Index for predicting postoperative cardiac complications.
- The index focuses on specific medical conditions and surgical risk factors.
*History of preoperative treatment with insulin*
- This is a component of the **Goldman Revised Cardiac Risk Index**, indicating **insulin-dependent diabetes mellitus**.
- Diabetes requiring insulin treatment is a significant risk factor for cardiac complications during surgery.
*History of preoperative serum creatinine >2.0 mg/dL*
- An elevated **serum creatinine** (>2.0 mg/dL) is a recognized component of the index, reflecting **renal insufficiency**.
- **Renal impairment** is associated with increased cardiac risk in the perioperative period.
*History of ischemic heart disease*
- This is a key component of the Goldman Revised Cardiac Risk Index, as a history of **ischemic heart disease** (e.g., prior myocardial infarction, angina) significantly increases perioperative cardiac risk.
- Patients with existing heart disease are more susceptible to cardiac events during and after surgery.
Geriatric Health Issues Indian Medical PG Question 9: Which of the following best describes the concept of 'Years of Potential Life Lost' (YPLL)?
- A. Years lost due to illness or morbidity
- B. Years lost due to premature mortality (Correct Answer)
- C. Years lost due to disability
- D. Years lost due to poor health quality
Geriatric Health Issues Explanation: ***Correct Answer: Years lost due to premature mortality***
- **Years of Potential Life Lost (YPLL)** is a measure of premature mortality, calculated by subtracting the age at death from a predetermined standard age (e.g., 75 or 65 years)
- It quantifies the **societal and economic impact** of deaths occurring before a statistically expected lifespan, giving more weight to deaths at younger ages
- YPLL emphasizes the burden of **early deaths** on society, making it particularly useful for prioritizing public health interventions
*Incorrect: Years lost due to illness or morbidity*
- This concept describes the **burden of living with illness**, not necessarily dying prematurely
- While related to health outcomes, it is distinct from YPLL, which specifically focuses on the impact of **death**
*Incorrect: Years lost due to disability*
- This is a component of **Disability-Adjusted Life Years (DALYs)**, specifically the **Years Lived with Disability (YLD)** component
- It does not directly account for **mortality**, but rather the impact of non-fatal health outcomes
- YLD measures the burden of living with health conditions, not years lost to premature death
*Incorrect: Years lost due to poor health quality*
- This is a broad term that can encompass various aspects of health
- While related to the overall societal health burden, it is not a specific, standardized metric like YPLL
- YPLL has a precise definition and calculation method focused exclusively on **premature death**
Geriatric Health Issues Indian Medical PG Question 10: WHO global target for prevention and control of non communicable diseases by 2025 is to decrease the prevalence of raised blood pressure (hypertension) by
- A. 75%
- B. 25% (Correct Answer)
- C. 90%
- D. 55%
Geriatric Health Issues Explanation: ***25%***
- The World Health Organization (WHO) set a **global target** to achieve a **25% relative reduction** in the prevalence of **raised blood pressure (hypertension)** by 2025 (compared to 2010 baseline).
- This target is part of the **WHO Global Action Plan for NCDs** and the Global Monitoring Framework to combat **non-communicable diseases (NCDs)**.
*75%*
- A 75% reduction in hypertension prevalence is an **unrealistically ambitious** target given current global health challenges and interventions.
- While significant reductions are desired, the evidence-based target set by WHO is a more achievable 25% reduction.
*90%*
- A 90% reduction is not one of the specifically stated **WHO global targets** for hypertension by 2025.
- Such a drastic reduction would require unprecedented public health interventions and is not supported by current evidence.
*55%*
- 55% is not a recognized **WHO target** for the prevention and control of hypertension by 2025.
- The established global target from the WHO NCD Global Monitoring Framework specifically focuses on a **25% relative reduction**.
