UPSC-CMS 2022 Practice Questions

Q: Of the following amino acids required by the human body, which one falls under the category of 'essential' amino acid?

Threonine. ***Threonine*** - **Threonine** is one of the nine **essential amino acids** that the human body cannot synthesize on its own. - It must be obtained through the **diet** to support protein synthesis and other vital bodily functions. *Arginine* - **Arginine** is generally considered a **conditionally essential** or **semi-essential amino acid**. - While the body can synthesize it, requirements may increase during periods of rapid growth, illness, or stress, making dietary intake important in those situations. *Proline* - **Proline** is a **non-essential amino acid**, meaning the human body can synthesize it from other precursors. - It plays a crucial role in the structure of **collagen** and connective tissue. *Serine* - **Serine** is also a **non-essential amino acid** that can be synthesized by the human body. - It is involved in the metabolism of fats, fatty acids, and the synthesis of various other biomolecules.

Q: Consider the following measures for making unlined katcha wells sanitary: 1. Deepening the bottom 2. Filling the well with clay up to the water level and with coarse sand above that level 3. Installing a hand pump with screen 4. Constructing a platform and drainage once the material used for filling is completely consolidated Which of the above measures are effective in making unlined katcha wells sanitary?

1, 2, 3 and 4. ***1, 2, 3 and 4*** - All four measures are crucial for improving the **sanitary conditions** of unlined 'katcha' wells and preventing contamination. - These steps collectively address issues like surface water intrusion, subsurface filtration, and safe water extraction. *2 and 3 only* - This option is incomplete as it misses other vital steps like **deepening the bottom** to access cleaner water strata and **constructing a proper platform and drainage** to prevent surface contamination. - Focusing solely on filling and pump installation is insufficient for comprehensive well sanitation. *1 and 2 only* - This option overlooks the importance of installing a **hand pump with a screen** for hygienic water extraction and constructing a **platform with drainage** to prevent surface water runoff into the well. - Simply deepening and filling does not guarantee safe water delivery or protect against surface pollutants. *1, 3 and 4 only* - This option omits the critical step of **filling the well with clay and coarse sand**, which acts as a natural filter to remove impurities from the water as it seeps into the well. - Without proper filtration, deepening and surface protection alone may not ensure safe water quality.

Q: As per the definition of the World Health Organization, 'late maternal death' is defined as the death of a woman from direct or indirect obstetric causes, after more than X days but less than one year after termination of pregnancy. Which one among the following is the correct value of X?

42. ***Correct: 42*** - According to the **World Health Organization (WHO)**, **late maternal death** is defined as the death of a woman from direct or indirect obstetric causes occurring **more than 42 days** but less than one year after termination of pregnancy. - This definition helps in categorizing and understanding the timeframe and causes of maternal mortality beyond the immediate postpartum period. - The **42-day threshold** distinguishes between direct maternal deaths (within 42 days) and late maternal deaths (42 days to 1 year). *Incorrect: 21* - This value is not used in the WHO definition for the onset of late maternal death. - The **42-day mark** is the internationally recognized threshold for distinguishing between the immediate postpartum period and late maternal complications. *Incorrect: 7* - Seven days is too short a period for a death to be classified as **"late maternal death"**; deaths within this timeframe fall under **direct maternal deaths** in the immediate postpartum period. - This period is often associated with immediate postpartum complications such as **postpartum hemorrhage**, **eclampsia**, or **early-onset puerperal sepsis**. *Incorrect: 84* - While 84 days (12 weeks) is a significant period in postpartum recovery for some physiological changes, it is not the specific threshold used by the **WHO** to define the beginning of **late maternal death**. - The international standard remains **42 days** (6 weeks) as the transition point between direct and late maternal deaths.

Q: The following table shows some of the pneumoconioses diseases along with the most implicated causative chemical agents. Which among the following represent the correct combinations of diseases and causative chemical agents? Select the correct answer using the code given below.

1 and 2. ***Correct: 1 and 2*** - **Statement 1 (Anthracosis - Coal dust)** is correct. Anthracosis, also known as **coal worker's pneumoconiosis**, is caused by chronic inhalation of coal dust particles [1]. - **Statement 2 (Byssinosis - Cotton dust)** is correct. Byssinosis is an occupational lung disease affecting **textile workers** exposed to cotton, flax, or hemp dust, causing airway obstruction. *Incorrect: 2 and 4* - Statement 4 is incorrect. **Siderosis** is caused by inhalation of **iron dust** (common in welders and miners), not asbestos [1]. Asbestos exposure causes **asbestosis** [1]. *Incorrect: 2 and 3* - Statement 3 is incorrect. **Bagassosis** is caused by inhalation of **sugarcane bagasse dust** (a hypersensitivity pneumonitis), not silica dust [1]. Silica causes **silicosis** [1]. *Incorrect: 1 and 3* - While statement 1 is correct (Anthracosis - Coal dust), statement 3 is incorrect as explained above (Bagassosis is caused by sugarcane bagasse dust, not silica dust) [1]. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. The Lung, p. 695.

Q: In a newborn, the Apgar score has been recorded at 1 minute of birth. Which one of the following best reflects the Apgar score of this newborn infant on a scale of 0 to 10?

3. ***3*** - The Apgar score is calculated based on five criteria: **Appearance**, **Pulse**, **Grimace**, **Activity**, and **Respiration** (APGAR). Each criterion is scored 0, 1, or 2. - Based on the given findings: - **Heart rate (Pulse)**: 92/min scores **1** (below 100/min). - **Respiratory effort (Respiration)**: Slow, irregular scores **1**. - **Muscle tone (Activity)**: Flaccid scores **0**. - **Reflex response (Grimace)**: No response scores **0**. - **Colour (Appearance)**: Body pink, extremities blue (acrocyanosis) scores **1**. - Summing these scores (1 + 1 + 0 + 0 + 1) gives a total Apgar score of **3**. *2* - This score would mean that the newborn has a **more severe depression** in vital signs compared to the actual findings. - A score of 2 would require at least one of the 1-point criteria to be a 0-point criterion or combination of a 0-point criterion become 1. *0* - An Apgar score of 0 would indicate that the infant has **no vital signs** (no heart rate, no respiratory effort, no muscle tone, no reflex response, and completely blue/pale). - This is not consistent with a heart rate of 92/min, slow/irregular respirations, and body pink color. *5* - An Apgar score of 5 would imply a **much healthier** newborn with better scores in most categories. - This would require findings such as a heart rate over 100 bpm, good crying, some flexion of extremities, or an all-pink appearance, which are not present here.
