UPSC-CMS 2013 - Pediatrics PYQs Practice Questions

Q: Most common cause of intestinal obstruction in childhood is:

Intussusception. ***Intussusception*** - **Intussusception** is the most common cause of intestinal obstruction in children between **3 months and 6 years** of age, particularly in infants. - It involves the telescoping of one segment of the intestine into an adjacent segment, leading to obstruction and potentially **ischemia**. *Mucoviscidosis* - **Mucoviscidosis**, or **cystic fibrosis**, can cause intestinal obstruction in newborns due to **meconium ileus**, but it is less common across the entire childhood period than intussusception. - While it is a significant cause of intestinal issues, its prevalence as the *most common overall cause* of obstruction in childhood is lower. *Hirschsprung's disease* - **Hirschsprung's disease** is a congenital absence of **ganglion cells** in the distal bowel, leading to functional obstruction, primarily in **neonates** and infants. - While an important cause of obstruction in early life, its overall incidence is less than intussusception, especially when considering the broader childhood age range. *Volvulus* - **Volvulus** is the twisting of a section of the intestine around its mesentery, which can occur at any age but is less frequent than intussusception in childhood. - It often presents as an acute surgical emergency with severe symptoms, but it is not the *most common* cause of obstruction across childhood.

Q: Apgar score is used in:

Newborn assessment. ***Newborn assessment*** - The **Apgar score** is a standardized clinical assessment tool used to evaluate the **physical condition of newborn infants** immediately after birth. - Developed by Dr. Virginia Apgar in 1952, it assesses five parameters at **1 minute and 5 minutes** after delivery (extended to 10, 15, and 20 minutes if needed). - The five components assessed are: - **A**ppearance (skin color): 0-2 points - **P**ulse (heart rate): 0-2 points - **G**rimace (reflex irritability): 0-2 points - **A**ctivity (muscle tone): 0-2 points - **R**espiration (breathing effort): 0-2 points - **Total score ranges from 0-10**, with scores of 7-10 considered normal, 4-6 indicating moderate distress, and 0-3 indicating severe distress requiring immediate resuscitation. - It helps **identify neonates requiring immediate medical intervention** and provides a standardized method for documenting the newborn's transition to extrauterine life. *Maternal health assessment* - Maternal health is assessed using different tools such as **antenatal risk scoring systems**, blood pressure monitoring, and laboratory investigations. - The Apgar score is specifically designed for **neonates, not mothers**. *Nutritional status evaluation* - Nutritional status is assessed using anthropometric measurements like **weight-for-height, BMI, MUAC** (mid-upper arm circumference), and biochemical markers. - The Apgar score does not evaluate nutritional parameters. *Infectious disease severity grading* - Infectious disease severity uses specific scoring systems like **APACHE II, SOFA score, or disease-specific criteria** (e.g., WHO classification for dengue severity). - The Apgar score is a **neonatal assessment tool**, not used for infectious disease evaluation.

Q: Child starts speaking short sentences by the age of :

24 months. ***24 months*** - By **24 months (2 years old)**, children typically begin to combine two or more words into **short sentences** and use about 50 words or more. - They also start to follow simple instructions and point to named objects and pictures. *15 months* - At **15 months**, children usually say a few words and can point to show what they want, but **short sentences** are not yet typical. They might use gestures more often. - Their vocabulary is still developing and usually consists of single words like "mama" or "dada." *12 months* - At **12 months (1 year old)**, most children are just starting to say their first words and are primarily communicating through gestures and sounds. - They are generally not forming combinations of words into sentences at this stage. *36 months* - By **36 months (3 years old)**, children have more advanced language skills, using **3-4 word sentences**, understanding most of what they hear, and having a vocabulary of several hundred words. - This age represents a more mature stage of language development than the initial formation of short sentences.
