Comprehensive Geriatric Assessment Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Comprehensive Geriatric Assessment. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Comprehensive Geriatric Assessment Indian Medical PG Question 1: Based on healthcare utility values and life expectancy, which of the following measures can be calculated? Consider a scenario where the average life expectancy for a woman in Japan is 87 years, and there is an increase in life expectancy due to healthcare advancements.
- A. HALE
- B. DALY
- C. DFLE
- D. QALY (Correct Answer)
Comprehensive Geriatric Assessment Explanation: ***QALY***
- **Quality-Adjusted Life Years (QALYs)** combine the length of life with the **quality of life** lived, taking into account healthcare utility values (e.g., from 0 for dead to 1 for perfect health).
- An increase in life expectancy due to healthcare advancements, coupled with assumed utility values, directly enables the calculation of QALYs gained or lost.
*HALE*
- **Health-Adjusted Life Expectancy (HALE)** is a measure of the average number of years that a person can expect to live in "**full health**" by adjusting for years lived in less than full health due to disease or injury.
- While it incorporates health status, it specifically focuses on time lived in full health rather than the utility-weighted quality of life over the entire lifespan as QALYs do.
*DALY*
- **Disability-Adjusted Life Years (DALYs)** measure the total number of healthy years lost due to disease, disability, or premature death.
- DALYs are a measure of disease burden, quantifying years lost, whereas QALYs are a measure of health gains or health states.
*DFLE*
- **Disability-Free Life Expectancy (DFLE)** measures the expected number of years an individual will live without disability.
- While it considers the absence of disability, it does not incorporate the concept of "utility values" or varying degrees of health-related quality of life beyond a binary disabled/non-disabled state, as QALYs do.
Comprehensive Geriatric Assessment Indian Medical PG Question 2: Which one of the following statements is false regarding chronic granulomatous disease?
- A. It is an autosomal dominant disease (Correct Answer)
- B. Recurrent staphylococcal infections are usual in this disease
- C. Nitro blue tetrazolium test is useful for screening
- D. It is characterized by abnormal bacterial phagocytosis
Comprehensive Geriatric Assessment Explanation: ### It is an autosomal dominant disease
- The most common and severe form of chronic granulomatous disease (CGD) is inherited as an **X-linked recessive disorder**.
- There are also autosomal recessive forms, but **never autosomal dominant inheritance**.
*Recurrent staphylococcal infections are usual in this disease*
- Patients with CGD are particularly susceptible to infections with **catalase-positive organisms** like *Staphylococcus aureus* because their phagocytes cannot effectively kill these microbes.
- This is due to a defect in the **NADPH oxidase enzyme**, which impairs the production of reactive oxygen species essential for bacterial killing [1].
*Nitro blue tetrazolium test is useful for screening*
- The **nitroblue tetrazolium (NBT) test** is a traditional screening method for CGD, as it detects the ability of phagocytes to produce a **respiratory burst** and reduce NBT dye [1].
- In CGD, the NBT dye remains yellow (unreduced) due to the absence or deficiency of NADPH oxidase activity.
*It is characterized by abnormal bacterial phagocytosis*
- CGD is characterized by **defective intracellular killing of phagocytosed bacteria and fungi**, not abnormal phagocytosis itself.
- Phagocytes (neutrophils, macrophages) can engulf microbes normally, but they fail to produce the **oxidative burst** necessary to destroy them [1].
Comprehensive Geriatric Assessment Indian Medical PG Question 3: The Confusion Assessment Method (CAM) is used for which of the following?
- A. Schizophrenia
- B. Delirium (Correct Answer)
- C. Dementia
- D. Depression
Comprehensive Geriatric Assessment 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.
Comprehensive Geriatric Assessment Indian Medical PG Question 4: The most comprehensive indicator of cost-effectiveness analysis is
- A. Number of heart attacks avoided
- B. Cost per life year gained
- C. Number of life years gained
- D. QALYs gained (Correct Answer)
Comprehensive Geriatric Assessment Explanation: ***QALYs gained***
- **Quality-Adjusted Life Years (QALYs)** is the most comprehensive measure in cost-effectiveness analysis as it accounts for both the quantity and quality of life
- Combines years of life added with a utility score reflecting health-related quality of life during those years
- Provides a holistic view that captures both mortality and morbidity benefits of interventions
*Number of heart attacks avoided*
- Specific to a single clinical outcome and does not account for other health benefits or adverse effects
- While important for cardiovascular interventions, it is too narrow to serve as a comprehensive cost-effectiveness indicator
- Does not capture broader impact on overall health, quality of life, or longevity
*Cost per life year gained*
- Focuses on the quantity (length) of life gained but does not consider the quality of those gained years
- An intervention might add years of life that are of poor quality, which this measure cannot differentiate
- Less comprehensive than QALYs as it misses the health status dimension
*Number of life years gained*
- Only considers the extension of life without incorporating health status or quality of life during additional years
- Provides an incomplete picture as it treats all life years equally regardless of health state
- A longer life with significant disability would be valued the same as healthy years
Comprehensive Geriatric Assessment Indian Medical PG Question 5: All of the following are components of the mental status examination EXCEPT:
- A. Insight
- B. Delirium (Correct Answer)
- C. Affect
- D. Judgment
Comprehensive Geriatric Assessment Explanation: **Delirium**
- **Delirium** itself is an **acute neuropsychiatric syndrome** characterized by a disturbance in attention and awareness, and it is a *diagnosis* or a *syndrome* that might be suggested by findings on a mental status examination, rather than a component *of* the examination.
- The mental status examination *assesses for signs* of delirium (e.g., inattention, disorganized thinking), but "delirium" is not a specific domain assessed like affect or insight.
*Insight*
- **Insight** is a key component of the mental status examination, referring to the patient's **understanding of their own mental illness** or situation.
- It assesses their awareness of symptoms, the belief in the need for treatment, and the recognition of the illness's impact.
*Affect*
- **Affect** is a component of the mental status examination that describes the **observable expression of emotion**, such as facial expressions, tone of voice, and body language.
- It is distinct from mood, which is the patient's subjective emotional state, and helps in evaluating emotional regulation.
*Judgment*
- **Judgment** is a component of the mental status examination that assesses the patient's ability to make **sound decisions** and understand the likely consequences of their behavior.
- This is often evaluated through hypothetical scenarios or by observing their real-life choices.
Comprehensive Geriatric Assessment Indian Medical PG Question 6: All of the following are part of Glasgow Coma Scale except
- A. Motor response
- B. Eye opening
- C. Verbal response
- D. Deep tendon reflexes (Correct Answer)
Comprehensive Geriatric Assessment Explanation: The **Glasgow Coma Scale (GCS)** assesses neurological function based on **eye opening**, **verbal response**, and **motor response** [1]. **Deep tendon reflexes** are part of a general neurological exam [2] but are not included in the GCS.
*Motor response*
- This is one of the three components of the **GCS** [1], assessing the patient's ability to move in response to commands or pain.
- It evaluates responses ranging from obeying commands to no motor response.
*Eye opening*
- This is a key component of the **GCS** [1], assessing the patient's level of consciousness based on their spontaneous or stimulated eye opening.
- Scores range from spontaneous eye opening to no eye opening.
*Verbal response*
- This is one of the three components of the **GCS** [1], evaluating the patient's ability to communicate verbally.
- It assesses responses from oriented conversation to no verbal response.
Comprehensive Geriatric Assessment Indian Medical PG Question 7: Anterior Drawer Test is used to diagnose tear of
- A. Medial meniscus
- B. Lateral meniscus
- C. Anterior Cruciate Ligament (Correct Answer)
- D. Posterior Cruciate Ligament
Comprehensive Geriatric Assessment Explanation: ***Anterior Cruciate Ligament***
- The **Anterior Drawer Test** assesses the integrity of the **Anterior Cruciate Ligament (ACL)** by evaluating anterior translation of the tibia relative to the femur.
- A positive test (excessive anterior movement) indicates a tear or injury to the **ACL**, which is a common knee injury often seen in athletes.
*Medial meniscus*
- Tears of the **medial meniscus** are typically diagnosed using tests like the **McMurray test** or **Apley grind test**, which stress the meniscus.
- While meniscal tears can cause knee pain and instability, they do not directly manifest as excessive anterior tibial translation in the **Anterior Drawer Test**.
*Lateral meniscus*
- Similar to the medial meniscus, tears of the **lateral meniscus** are evaluated with tests such as the **McMurray test** (internal rotation) or **Apley grind test**.
- The **Anterior Drawer Test** is specific for ligamentous instability and is not a primary diagnostic tool for meniscal injuries.
*Posterior Cruciate Ligament*
- The integrity of the **Posterior Cruciate Ligament (PCL)** is assessed by the **Posterior Drawer Test**, which checks for posterior translation of the tibia.
- A positive **Posterior Drawer Test** indicates a PCL tear, whereas the **Anterior Drawer Test** specifically evaluates the **ACL**.
Comprehensive Geriatric Assessment Indian Medical PG Question 8: Glasgow coma scale includes all except
- A. Swallowing reflex (Correct Answer)
- B. Motor response
- C. Eye opening
- D. Verbal response
Comprehensive Geriatric Assessment Explanation: ***Swallowing reflex***
- The **Glasgow Coma Scale (GCS)** assesses **neurological function** through **eye opening**, **verbal response**, and **motor response**. [1]
- The swallowing reflex is an **involuntary brainstem reflex** used to assess a patient's ability to protect their airway but is not a component of the GCS. [2]
*Motor response*
- This component evaluates a patient's ability to **obey commands**, localize pain, withdraw from pain, or exhibit abnormal flexion/extension.
- It is one of the three main categories used to score a patient's consciousness level in the GCS. [1]
*Eye opening*
- This component assesses a patient's **spontaneous eye-opening** or opening in response to speech or pain.
- It provides an indication of **arousal** and a patient's level of consciousness within the GCS. [1]
*Verbal response*
- This component evaluates a patient's ability to speak, assessing whether they are **oriented**, confused, or making inappropriate sounds.
- It is crucial for understanding a patient's **cognitive function** and is one of the three parameters in the GCS. [1]
Comprehensive Geriatric Assessment Indian Medical PG Question 9: Which of the following is the most common cause of reversible dementia in the geriatric population?
- A. Depression (Correct Answer)
- B. Normal Pressure Hydrocephalus
- C. Hypothyroidism
- D. Vitamin B12 deficiency
Comprehensive Geriatric Assessment Explanation: The correct answer is **Depression**. In the geriatric population, depression often presents with cognitive impairment, memory loss, and poor concentration, a clinical entity known as **Pseudodementia**. It is the most common cause of reversible cognitive decline [1]. Unlike true dementia (e.g., Alzheimer’s), patients with pseudodementia typically provide "I don't know" answers during testing, appear distressed by their deficits, and show significant improvement with antidepressant therapy or ECT. Analysis of Incorrect Options: **Normal Pressure Hydrocephalus (NPH):** Characterized by the triad of gait ataxia, urinary incontinence, and dementia ("Wet, Wobbly, and Wacky"). While reversible via a ventriculoperitoneal shunt, it is statistically less common than depression [1]. **Hypothyroidism:** Can cause cognitive slowing and "myxedema madness." While a standard part of the dementia workup (checking TSH), it is a less frequent cause of isolated reversible dementia compared to psychiatric illness. **Vitamin B12 Deficiency:** Leads to Subacute Combined Degeneration of the spinal cord and cognitive changes. While common in the elderly due to atrophic gastritis, it ranks below depression in prevalence as a primary cause of reversible cognitive impairment [1].
Comprehensive Geriatric Assessment Indian Medical PG Question 10: Which of the following does not change in old age?
- A. GFR
- B. Glucose tolerance
- C. Haematocrit (Correct Answer)
- D. Blood pressure
Comprehensive Geriatric Assessment Explanation: In geriatric medicine, distinguishing between normal physiological aging and pathological changes is crucial for the NEET-PG exam.
### **Explanation of the Correct Answer**
**C. Haematocrit:** Under normal conditions, **Haematocrit (and Hemoglobin levels) does not significantly change with age.** While the bone marrow becomes more fatty and its "reserve" capacity to respond to stress (like acute hemorrhage) decreases, the baseline production of red blood cells remains stable. If an elderly patient presents with anemia, it should always be investigated as a pathological process (e.g., iron deficiency, occult GI bleed, or chronic disease) rather than being dismissed as "normal aging."
### **Analysis of Incorrect Options**
* **A. GFR (Glomerular Filtration Rate):** GFR decreases progressively after the age of 30-40 at a rate of approximately **0.75–1 mL/min/year**. This is due to nephrosclerosis and a reduction in the number of functional nephrons. [1]
* **B. Glucose Tolerance:** Peripheral insulin resistance increases and pancreatic beta-cell sensitivity decreases with age. [1] This leads to a decline in glucose tolerance, often resulting in higher postprandial blood glucose levels in the elderly.
* **C. Blood Pressure:** Both systolic blood pressure and pulse pressure typically **increase** with age due to the loss of arterial elasticity and increased stiffness of large conduit arteries (arteriosclerosis). [1]
### **High-Yield Clinical Pearls for NEET-PG**
* **Unchanged Parameters:** Along with Haematocrit, other parameters that remain relatively stable include **Blood Volume, Serum Electrolytes, and Liver Function Tests (LFTs)**.
* **Creatinine Paradox:** Serum Creatinine may remain in the "normal range" in the elderly despite a decreased GFR because of a concurrent decrease in muscle mass (sarcopenia).
* **Vital Capacity:** While Total Lung Capacity remains constant, **Vital Capacity decreases** and **Residual Volume increases** due to loss of elastic recoil. [1]
