Developmental Milestones Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Developmental Milestones. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Developmental Milestones Indian Medical PG Question 1: A normally growing child smiles back (social smile) at around what age?
- A. 2-4 weeks
- B. 4-6 weeks
- C. 6-8 weeks (Correct Answer)
- D. 8-10 weeks
Developmental Milestones Explanation: ***6-8 weeks***
- A **social smile** is a significant developmental milestone indicating emotional and social development, typically appearing around **2 months of age** (6-8 weeks).
- It signifies the infant's ability to recognize and respond to human faces, fostering early parent-child bonding.
*2-4 weeks*
- At this age, infants typically exhibit **reflexive smiles**, which are not true social smiles as they do not respond to external stimuli.
- Their primary focus is on basic physiological needs like feeding and sleeping.
*4-6 weeks*
- While infants may show some early signs of engagement, a consistent and clear **social smile** is usually not fully established yet.
- They are more focused on tracking objects and showing early visual preferences.
*8-10 weeks*
- By this age, the **social smile** should already be well-established, as it typically appears by 6-8 weeks.
- If a social smile has not appeared by 10 weeks, developmental assessment and monitoring for other milestones would be warranted.
Developmental Milestones Indian Medical PG Question 2: A 3-year-old child with delayed speech development, prefers to play alone and is not making friends. The likely diagnosis is
- A. Autism (Correct Answer)
- B. Specific learning disability
- C. Rett's syndrome
- D. ADHD
Developmental Milestones Explanation: ***Autism***
- **Delayed speech development**, a preference for playing alone, and difficulty making friends are classic diagnostic criteria for **Autism Spectrum Disorder (ASD)**.
- ASD is characterized by persistent deficits in **social communication and social interaction** across multiple contexts, along with restricted, repetitive patterns of behavior, interests, or activities.
*Specific learning disability*
- A specific learning disability primarily affects academic skills (e.g., **reading, writing, arithmetic**) in individuals with otherwise average intelligence.
- While it can impact social interactions due to frustration or self-esteem issues, its core features are not primarily related to delayed speech or intrinsic difficulties in social engagement.
*Rett's syndrome*
- Rett's syndrome is a rare **neurodevelopmental disorder** that almost exclusively affects females and is caused by mutations in the MECP2 gene.
- It is characterized by initial normal development followed by a regression of skills, including **purposeful hand movements**, speech, and gait, often presenting with stereotypic hand-wringing.
- The clinical presentation here shows early developmental concerns without regression, making ASD more likely.
*ADHD*
- **Attention-deficit/hyperactivity disorder (ADHD)** is characterized by symptoms of **inattention, hyperactivity, and impulsivity**.
- While children with ADHD may have difficulty with social interactions due to impulsivity or inattention, delayed speech development and a consistent preference for solitary play are not primary diagnostic features.
Developmental Milestones Indian Medical PG Question 3: Absence of which of the given milestones in a 3 year old child should be called delayed development?
- A. Hopping on one leg
- B. Catching a ball reliably
- C. Drawing a square
- D. Feeding by spoon (Correct Answer)
Developmental Milestones Explanation: ***Feeding by spoon***
- The ability to **feed oneself with a spoon** is typically achieved by **15 to 18 months of age**, making its absence in a 3-year-old a sign of delayed development.
- This milestone reflects both **fine motor coordination** and **self-help skills**.
*Hopping on one leg*
- **Hopping on one leg** is a gross motor skill usually developed between **4 and 5 years of age**, so a 3-year-old not yet doing this is within the normal developmental range.
- This skill requires advanced **balance** and **coordination**.
*Catching a ball reliably*
- **Catching a ball reliably** typically emerges around **4 to 5 years of age**, as it requires good **hand-eye coordination** and **anticipation skills**.
- A 3-year-old's inability to catch a ball reliably is not considered delayed.
*Drawing a square*
- The ability to **draw a square** is usually achieved by **4 to 5 years of age**, requiring fine motor precision and visuomotor integration.
- At 3 years, children are more likely to be able to copy a **circle** or **vertical line**.
Developmental Milestones Indian Medical PG Question 4: A child of 4 years can do all of the following except:
- A. Copies triangle (Correct Answer)
- B. Skips
- C. Tell a story
- D. Goes down stairs one foot per step
Developmental Milestones Explanation: ***Copies triangle***
- Drawing a **triangle** typically develops around **5 to 6 years of age** as it requires more advanced fine motor and visual-motor integration skills.
- At 4 years, a child can usually copy simpler shapes like a **square** or a **cross**, but not a triangle.
*Skips*
- **Skipping** is a gross motor skill that often emerges around **4 to 5 years of age**.
- Many 4-year-olds can coordinate the reciprocal motion required to skip, even if not perfectly.
*Tell a story*
- By 4 years, children have developed sufficient language skills to **recount events** and **create simple narratives**, often with imaginative elements.
- They can use several sentences to tell a story and understand the concept of a beginning, middle, and end.
*Goes down stairs one foot per step*
- Descending stairs with one foot per step is a typical gross motor milestone achieved by most children around **3 to 4 years of age**.
- This shows improved balance and coordination compared to using both feet on each step.
Developmental Milestones Indian Medical PG Question 5: A child with pervasive developmental disorder will have all of the following except:
- A. Stereotyped behaviour
- B. Reduced social interaction
- C. Poor language skills
- D. Impaired cognition (Correct Answer)
Developmental Milestones Explanation: ***Impaired cognition***
- While some individuals with **pervasive developmental disorders (PDDs)** may have comorbid intellectual disability, **impaired cognition is not a universal or defining characteristic** of PDDs.
- Many individuals with PDDs, particularly those with **Asperger's syndrome**, have **average or above-average intelligence**.
- Intelligence quotient (IQ) varies widely across the autism spectrum, making cognitive impairment a non-essential feature.
*Stereotyped behaviour*
- **Stereotyped and repetitive behaviors** (e.g., hand flapping, rocking, rigid adherence to routines) are a **core diagnostic criterion** for PDDs, including autism spectrum disorder.
- These behaviors are part of the **restricted, repetitive patterns of behavior, interests, or activities** domain in diagnostic criteria.
*Reduced social interaction*
- Significant **deficits in social interaction and communication** are a **hallmark feature** of PDDs.
- This manifests as difficulty with reciprocal social communication, impaired ability to interpret social cues, and challenges in forming age-appropriate peer relationships.
*Poor language skills*
- **Communication impairments**, including poor language skills, are a **common feature** of PDDs, especially in classical autism.
- This can include delayed speech development, unusual language patterns (e.g., **echolalia**, pronoun reversal), or complete absence of verbal communication in severe cases.
Developmental Milestones Indian Medical PG Question 6: Which of the following statements about development milestones at 6 months of age is incorrect?
- A. Watching self in mirror
- B. Pincer grasp (Correct Answer)
- C. Sitting in tripod position
- D. Monosyllable sounds
Developmental Milestones Explanation: ***Pincer grasp***
- The **pincer grasp** (using the index finger and thumb to pick up small objects) typically develops much later, usually around **9-12 months** of age.
- At 6 months, infants are usually developing a **palmar grasp** or raking motion, not the fine motor control required for a pincer grasp.
- This milestone is **NOT expected at 6 months**, making this the incorrect statement.
*Watching self in mirror*
- By 6 months, infants typically show **interest in their own reflection** and will watch themselves in a mirror, often smiling or vocalizing at the image.
- This is a normal social-emotional milestone at this age.
*Sitting in tripod position*
- Many 6-month-old infants are able to sit with support, and often begin to sit independently for short periods, frequently using their arms for stability in a **tripod position**.
- This is a common and expected gross motor milestone at this age.
*Monosyllable sounds*
- Around 6 months, infants commonly start to produce **monosyllable sounds** like "ba-ba," "da-da," or "ma-ma," as part of their early babbling.
- This is a normal and expected language development milestone.
Developmental Milestones Indian Medical PG Question 7: A child can ride a tricycle, copies a circle, knows name and gender. The developmental age of this child is
- A. 4 years
- B. 5 years
- C. 2 years
- D. 3 years (Correct Answer)
Developmental Milestones Explanation: ***3 years***
- A child who can **ride a tricycle**, **copy a circle**, and knows their **name and gender** has achieved developmental milestones typically seen around **3 years of age**.
- **Riding a tricycle** demonstrates advanced gross motor skills, while **copying a circle** indicates fine motor skill development. **Knowing name and gender** points to cognitive and social-emotional understanding.
*4 years*
- By 4 years, a child can typically **hop on one foot**, **draw a square**, and **tell stories**.
- While they might refine skills acquired at 3, the listed milestones are primary for the 3-year mark.
*5 years*
- A 5-year-old usually can **skip**, **draw a triangle**, and **count 10 or more objects**.
- These milestones represent further advancements beyond those described in the question.
*2 years*
- At 2 years, a child typically starts to **kick a ball**, **draw a straight line**, and can say **two-to-four-word sentences**.
- The skills described (tricycle, circle) are generally too advanced for a 2-year-old.
Developmental Milestones Indian Medical PG Question 8: Bilateral grasp is seen at what age?
- A. 6 months
- B. 3 months
- C. 9 months
- D. 5 months (Correct Answer)
Developmental Milestones Explanation: ***5 months***
- At **5 months**, infants typically develop the ability to **reach for and grasp objects with both hands**, demonstrating improved coordination and control.
- This age marks a transition from reflexive grasping to more intentional and bilateral manipulation of objects.
*6 months*
- While fine motor skills continue to develop at 6 months, **bilateral grasp** is usually well-established by this age, having emerged earlier.
- At 6 months, infants are often progressing towards **unilateral grasp** and transferring objects between hands.
*3 months*
- At **3 months**, infants are typically still developing head control and beginning to reach, but their grasp is often still a **reflexive palmar grasp** rather than intentional bilateral grasping.
- Reaching at this age is usually more swiping or batting at objects rather than a coordinated grasp.
*9 months*
- By **9 months**, infants have developed more refined pincer grasp and are capable of complex manipulation of objects with a single hand.
- **Bilateral grasp** is a much earlier developmental milestone than the advanced skills seen at 9 months.
Developmental Milestones Indian Medical PG Question 9: At what age do most children reach a height of 100 cm?
- A. 3 years
- B. 2 years
- C. 5 years
- D. 4 years (Correct Answer)
Developmental Milestones Explanation: **4 years**
- Most children reach approximately **100 cm** in height around their fourth birthday.
- This represents a doubling of their birth length, as the average birth length is around 50 cm.
*2 years*
- A child's height at 2 years is typically around **86-89 cm**.
- While they have often doubled their birth weight by then, they haven't typically reached 100 cm in height.
*3 years*
- By 3 years of age, the average height for a child is usually between **94-96 cm**.
- This is close, but still generally less than the 100 cm mark.
*5 years*
- Children aged 5 years are generally taller than **100 cm**, typically averaging around **108-110 cm**.
- Reaching 100 cm would occur well before this age.
Developmental Milestones Indian Medical PG Question 10: At what month does a baby typically sit in the tripod position?
- A. 9 months
- B. 8 months
- C. 5 months
- D. 6 months (Correct Answer)
Developmental Milestones Explanation: **6 months**
- Around **6 months** of age, infants typically develop sufficient **head control** and **trunk strength** to sit unsupported, often using their hands for balance in a **tripod position**.
- This developmental milestone is crucial for further motor development, enabling improved visual exploration and hand use.
*5 months*
- At **5 months**, infants can usually **roll over** and support themselves on their forearms, but generally lack the **trunk stability** for unsupported sitting.
- While they might briefly sit with support, the sustained **tripod position** is typically not achieved until later.
*8 months*
- By **8 months**, most infants can sit **unsupported for extended periods** and often begin to **crawl** or pull themselves to stand.
- The tripod position is usually a precursor to fully unsupported sitting, which is well-established by this age.
*9 months*
- At **9 months**, infants are typically highly mobile, often **crawling**, **cruising** (walking while holding onto furniture), and sitting completely **independently** without needing hand support.
- The need for a tripod position for stability would indicate a **developmental delay** at this age.
