NEET-PG 2013 Practice Questions

Q: Which of the following nerves transmits impulses originating from the vestibular apparatus?

Cranial nerve VIII. ***Cranial nerve VIII*** - The **vestibulocochlear nerve (CN VIII)** is responsible for transmitting both auditory (cochlear branch) and balance (vestibular branch) information to the brain [1], [2]. - The **vestibular apparatus** in the inner ear detects head movements and position, and its impulses are carried by the vestibular part of CN VIII [2]. *Cranial nerve XI* - **Cranial nerve XI (Accessory nerve)** primarily controls the **sternocleidomastoid** and **trapezius muscles**, involved in head and shoulder movement. - It has no role in transmitting sensory information from the vestibular apparatus or the inner ear. *Cranial nerve VII* - **Cranial nerve VII (Facial nerve)** innervates the **muscles of facial expression**, carries taste sensation from the anterior two-thirds of the tongue, and supplies several glands. - It is not involved in transmitting impulses related to balance from the vestibular apparatus. *Cranial nerve II* - **Cranial nerve II (Optic nerve)** is responsible for **vision**, transmitting visual information from the retina to the brain. - It has no function related to the vestibular system or balance.

Q: Objectives of National Mental Health programme are all except -

Provide free antipsychotic drugs to all. ***Provide free antipsychotic drugs to all*** - While ensuring access to essential medicines is important, the National Mental Health Programme (NMHP) does not explicitly guarantee **free antipsychotic drugs to all** individuals, as the scope of provision can depend on various factors like specific conditions, and availability of resources. - The primary objectives are broader and focus on overall mental health care delivery and promotion, rather than a universal provision of specific medications, especially when the need for such drugs may not apply to "all" individuals in the population. *Provide accessibility of mental health care* - A core objective of the NMHP is to make **mental health care accessible** to all individuals, particularly in rural and underserved areas. - This involves establishing services at primary, secondary, and tertiary care levels. *Promote community participation* - The NMHP aims to foster **community involvement** in mental health awareness, destigmatization, and support for individuals with mental illness. - This includes engaging communities in prevention, promotion, and rehabilitation efforts. *Promote application of mental health knowledge* - A key goal is to enhance the **understanding and application of mental health knowledge** among healthcare professionals, policymakers, and the general public. - This objective supports evidence-based practices and informed decision-making in mental health care.

Q: A child is obese if he/she has weight-for-height according to growth chart standards -

2 SD from median weight for height. ***2 SD from median weight for height*** - According to **WHO growth chart standards**, a child is considered **obese** if their weight-for-height measurement is **≥ +2 standard deviations (SD)** above the median. - This cutoff (weight-for-height Z-score ≥ +2 SD) signifies a high degree of adiposity relative to height, indicating significant risk of obesity-related health issues. - Alternatively, **BMI-for-age ≥ +2 SD** can also be used to define childhood obesity. *1 SD from median weight for height* - A weight-for-height between **+1 SD and +2 SD** above the median typically indicates **overweight** (at risk of obesity), but not yet obesity, according to WHO growth standards. - While concerning and requiring monitoring, it does not meet the criteria for obesity. *3 SD from median weight for height* - A weight-for-height of **≥ +3 SD** above the median is classified as **severe obesity** or **severe acute malnutrition** (if severely underweight). - This represents an even more extreme level of adiposity than the standard definition of obesity. *None of the options* - This option is incorrect because **≥ +2 SD from the median weight for height** is the internationally recognized WHO threshold for classifying obesity in children based on growth charts.

Q: Most common cause of facial nerve palsy:

Idiopathic Bell's palsy. ***Idiopathic Bell's palsy*** - **Bell's palsy** is the most common cause of **facial nerve palsy**, accounting for approximately 60-75% of cases. - It is an **idiopathic** condition, meaning its exact cause is unknown, although it is often linked to viral infections (e.g., herpes simplex virus). [1] *Mastoid surgery* - **Iatrogenic facial nerve injury** during mastoidectomy is a known complication, but it is a relatively rare cause of facial nerve palsy. - While it can cause significant palsy, the incidence is low compared to Bell's palsy. *Herpes zoster oticus* - This condition, also known as **Ramsay Hunt syndrome**, is a cause of facial nerve palsy associated with a **vesicular rash** (zoster) in the ear canal or on the face. - While it is a significant cause of viral-induced facial palsy, it is less common than idiopathic Bell's palsy. *Chronic suppurative Otitis media* - **Chronic otitis media** can, in rare cases, lead to facial nerve palsy due to persistent inflammation spreading to the facial nerve. [2] - This is a less common etiology than Bell's palsy and would typically present with a history of recurrent ear discharge and hearing loss.

Q: In medico-legal cases, a Class I judicial magistrate has the power to give a maximum punishment of:

3 yr, Rs. 10000. **3 yr, Rs. 10000** - A **Class I Judicial Magistrate** is empowered to award a maximum imprisonment of **3 years** and/or a fine of up to **Rs. 10,000**. - This is stipulated under **Section 29(2) of the Code of Criminal Procedure (CrPC), 1973**, which defines the sentencing powers of different judicial magistrates. *5 yr, Rs. 3000* - This option incorrectly states both the maximum imprisonment and the maximum fine for a Class I Judicial Magistrate. - The maximum imprisonment for a Class I Judicial Magistrate is **3 years**, not 5, and the maximum fine is **Rs. 10,000**, not Rs. 3,000. *5 yr, Rs. 5000* - This option indicates an imprisonment period of **5 years**, which is incorrect for a Class I Judicial Magistrate. - While the fine amount is closer to the correct value than in some other incorrect options, the imprisonment period remains inaccurate. *3 yr, Rs. 3000* - While the imprisonment period of **3 years** is correct for a Class I Judicial Magistrate, the maximum fine mentioned – Rs. 3,000 – is incorrect. - The correct maximum fine that can be imposed is **Rs. 10,000**.

Q: Kveim test (historical) is used for diagnosis of

None of the options. ***None of the options.*** - While the Kveim test was historically used to diagnose **sarcoidosis**, it is now obsolete. - The Kveim test involved injecting a sarcoid tissue extract and observing for a reaction, but it is no longer used due to concerns about **specificity**, **standardization**, and **transmission of infectious agents**. *Wegeners granulomatosis* - This condition is now known as **Granulomatosis with Polyangiitis (GPA)**. - Diagnosis relies on clinical features, imaging, **biopsy showing granulomatous inflammation and vasculitis**, and **antineutrophil cytoplasmic antibodies (ANCAs)**, particularly **c-ANCA**. *Graves disease* - This is an **autoimmune hyperthyroid condition** diagnosed by specific thyroid hormone levels (low TSH, high free T3/T4) [2]. - The presence of **TSH receptor antibodies (TRAb)** or thyroid-stimulating immunoglobulins (TSI) are key diagnostic markers. *Sarcoidosis* - The Kveim test was indeed historically associated with sarcoidosis, but it is **no longer a current diagnostic tool**. - Current diagnosis involves clinical presentation, **imaging (chest X-ray/CT)** showing bilateral hilar lymphadenopathy, and **biopsy** demonstrating non-caseating granulomas [1].

Q: When should semen analysis be done?

After liquefaction with thorough mixing. ***After liquefaction with thorough mixing*** - Semen analysis should be performed **after complete liquefaction** (typically within 20-30 minutes, maximum 60 minutes) followed by **thorough mixing**. - According to **WHO guidelines (2010, 2021)**, the sample must first liquefy completely at room temperature, then be mixed well before microscopic examination. - This ensures accurate assessment of **sperm concentration, motility, and morphology** without artifacts from viscous semen. - The standard practice is to examine within **60 minutes of collection** but only after liquefaction is complete. *After 30-60 mins irrespective of liquefaction* - The phrase "irrespective of liquefaction" is **incorrect** as analysis before complete liquefaction leads to inaccurate results. - Performing analysis on a non-liquefied sample can cause **underestimation of sperm motility** and difficulty in proper microscopic assessment. - Liquefaction status must be assessed before proceeding with analysis. *As early as possible* - Analyzing too early before **liquefaction** (which typically takes 20-30 minutes) will yield inaccurate results. - A viscous, non-liquefied sample impairs proper **sperm movement assessment** and mixing. *After 15-30 mins irrespective of liquefaction* - While 30 minutes may be sufficient for many samples to liquefy, the phrase "irrespective of liquefaction" makes this incorrect. - Some samples may require up to **60 minutes** to liquefy completely, and analysis should not proceed until liquefaction is confirmed.

Q: Most common cause of post-measles death?

Pneumonia. ***Pneumonia*** - **Pneumonia**, particularly secondary bacterial pneumonia, is the **most common cause of death** in children following a measles infection. - Measles causes **immune suppression** and damage to the respiratory epithelium, making individuals vulnerable to severe respiratory infections. *SSPE* - **Subacute sclerosing panencephalitis (SSPE)** is a rare, fatal, late complication of measles, occurring years after the initial infection. - While always fatal, its rarity means it is not the most common cause of overall measles-related mortality. *Myocarditis* - **Myocarditis**, inflammation of the heart muscle, can be a rare complication of measles, but it is not the leading cause of death. - Cardiac complications are less frequently observed as the primary cause of death compared to respiratory infections. *Diarrhea* - **Diarrhea** is a common complication of measles, especially in malnourished children, and can contribute to mortality due to **dehydration** and electrolyte imbalances. - However, severe respiratory complications like pneumonia are still responsible for a higher proportion of measles-related deaths.

Q: True about delirium is all Except:

Preserved attention. ***Preserved attention*** - A key feature of **delirium** is a **disturbance in attention**, making it difficult to focus, sustain, or shift attention. - Therefore, **preserved attention** is inconsistent with a diagnosis of delirium. *Hallucination* - **Hallucinations**, particularly visual, are common in delirium and often contribute to the patient's distress and altered perception of reality. - They tend to be vivid, fleeting, and can be frightening. *Disturbed sleep* - **Sleep-wake cycle disturbances** are a hallmark of delirium, often manifesting as insomnia, daytime sleepiness, or a disrupted, fragmented sleep pattern. - This disturbance is part of the global alteration in brain activity. *Disorientation* - **Disorientation**, especially to time, place, and sometimes person, is a frequent symptom of delirium, reflecting the patient's impaired cognitive function. - It indicates a significant impairment in awareness of one's surroundings.

Q: All are true about delirium tremens, except:

Normal sleep-wake cycle. ***Normal sleep wake cycle*** - Delirium tremens is characterized by a **disrupted sleep-wake cycle**, often with **insomnia** and **nocturnal exacerbation** of symptoms, making a normal sleep-wake cycle an incorrect statement. - The brain's regulatory mechanisms for sleep are significantly impaired due to the withdrawal of alcohol's suppressive effects. *Clouding of consciousness* - **Clouding of consciousness** is a hallmark feature of delirium tremens, representing a reduced awareness of the environment and impaired attention. - Patients often present with **disorientation** regarding time, place, and person. *Visual hallucinations* - **Visual hallucinations** are very common in delirium tremens, often described as vivid, frightening, and involving small animals or insects. - These hallucinations contribute to the patient's **agitation** and fear. *Coarse tremors* - **Coarse tremors**, particularly of the hands and face, are a classic physical sign of alcohol withdrawal and an integral part of delirium tremens. - These tremors are due to the **overactivity of the sympathetic nervous system** as the inhibitory effects of alcohol wear off.
