A paediatric registrar assesses a 5-year-old boy in the emergency department with a painful, swollen right thigh. The mother states he fell off a swing 6 hours ago. X-ray shows a spiral fracture of the right femur. The child has had three previous attendances in the past year for injuries: a bruised cheek (fell into door), a burnt hand (touched radiator), and a cut lip (fell off bed). Which factor in the history is most predictive of this being non-accidental injury?
A 18-month-old girl is seen in clinic for poor weight gain. She was born at term with birthweight on the 50th centile. Her weight is now on the 2nd centile, having progressively fallen from the 25th centile at 6 months. She is walking well, says 10 words, and examination reveals no dysmorphic features. Parents report she is a 'fussy eater' but takes a varied diet. There is no vomiting or diarrhoea. What is the most appropriate initial investigation?
A school nurse is asked to review a 6-year-old girl whose teacher reports that she frequently appears tired, wears dirty clothes, and often comes to school without lunch or appropriate clothing for the weather. The child's academic performance has declined. Her growth chart shows she has been following the 25th centile consistently. What type of child maltreatment does this scenario most likely represent?
A 30-month-old child is brought to the GP for a developmental review. The mother is concerned that the child is not yet talking in sentences. The child can say approximately 20 single words, follows simple one-step commands, plays alongside other children, can build a tower of 6 cubes, and runs well. What is the most appropriate management?
A 4-year-old boy presents to the emergency department with his father, who reports the child fell down stairs 2 hours ago. Examination reveals multiple bruises of varying colours on the trunk and upper arms, a swollen right forearm with tenderness, and the child appears withdrawn and avoids eye contact. X-ray confirms a transverse fracture of the right radius. Which aspect of this presentation is most concerning for non-accidental injury?
A GP reviews a 6-month-old infant for developmental assessment. The parents report that the baby can roll from prone to supine, reaches for objects with both hands, and babbles using different consonant sounds. However, the infant does not yet have head control when pulled to sit. What is the most appropriate next step?
A paediatric junior doctor attends safeguarding training on recognising patterns of bruising in children. Which statement about bruising in children and safeguarding concerns is correct?
A practice nurse is reviewing immunisation records and notes that several children have crossed centiles on their growth charts. Which pattern of centile crossing on a growth chart is most likely to represent normal variation rather than pathology?

A 10-year-old girl is reviewed in clinic for short stature. Height is on the 0.4th centile, weight on the 9th centile. She has always been small but growth velocity has been normal. Both parents are short (father 162cm, mother 150cm). Bone age matches chronological age. She is otherwise well with normal examination findings. Thyroid function and coeliac screening are normal. Mid-parental height calculation places target centile range between 2nd and 25th centiles. Evaluating the need for further investigation, what is the most appropriate management?
Growth, Development & Safeguarding UK Medical PG Practice Questions and MCQs
Question 131: A paediatric registrar assesses a 5-year-old boy in the emergency department with a painful, swollen right thigh. The mother states he fell off a swing 6 hours ago. X-ray shows a spiral fracture of the right femur. The child has had three previous attendances in the past year for injuries: a bruised cheek (fell into door), a burnt hand (touched radiator), and a cut lip (fell off bed). Which factor in the history is most predictive of this being non-accidental injury?
- A. The spiral pattern of the femoral fracture
- B. The delay of 6 hours before seeking medical attention
- C. The pattern of repeated presentations with injuries (Correct Answer)
- D. The mechanism of falling off a swing
- E. The child's age of 5 years
Explanation: ***The pattern of repeated presentations with injuries***- A history of **multiple presentations** for different, often vague, injuries (bruises, burns, cuts) over a short period (within a year) is a significant **red flag** for non-accidental injury or neglect.- The **cumulative nature** and variety of these unexplained or poorly explained injuries, rather than any single event, are highly suggestive of an underlying pattern of abuse.*The spiral pattern of the femoral fracture*- While **spiral fractures** can be indicative of torsion forces often seen in abuse, they can also occur accidentally, particularly in active children from significant falls or twisting mechanisms.- The isolated finding of a spiral fracture, without other concerning factors, is not as predictive of abuse as the overall **pattern of injury presentations**.*The delay of 6 hours before seeking medical attention*- A **delay in seeking medical attention** for a significant injury is a concerning sign in potential non-accidental injury cases, as it may suggest reluctance to present the child or an attempt to conceal the injury's origin.- However, for an initial fall, a 6-hour delay might sometimes be attributed to parents monitoring the child or difficulty accessing care, making it less specific than a pattern of prior injuries.*The mechanism of falling off a swing*- Falling off a swing is a common and **plausible accidental mechanism** for injuries in children, including long bone fractures, due to the potential for significant force upon impact.- Because it provides an innocent explanation, this specific mechanism itself does not directly suggest non-accidental injury; rather, it's the discrepancy between the story and the injury, or other factors, that would raise suspicion.*The child's age of 5 years*- Children aged five are typically very active and mobile, making them naturally prone to **accidental injuries** as they explore their environment and engage in physical play.- While very young, non-ambulatory infants have a higher statistical risk for non-accidental injury with certain fractures, being five years old is not inherently a predictive factor for non-accidental injury.
Question 132: A 18-month-old girl is seen in clinic for poor weight gain. She was born at term with birthweight on the 50th centile. Her weight is now on the 2nd centile, having progressively fallen from the 25th centile at 6 months. She is walking well, says 10 words, and examination reveals no dysmorphic features. Parents report she is a 'fussy eater' but takes a varied diet. There is no vomiting or diarrhoea. What is the most appropriate initial investigation?
- A. Coeliac serology (anti-TTG antibodies)
- B. Sweat test for cystic fibrosis
- C. Thyroid function tests
- D. Full blood count and ferritin
- E. Three-day food diary (Correct Answer)
Explanation: ***Three-day food diary*** - In a child with **faltering growth** (failure to thrive) and no organic symptoms like vomiting or diarrhea, assessing **nutritional intake** is the primary first step. - A **three-day food diary** provides an objective evaluation of calorie consumption and feeding behaviors in a child described as a **'fussy eater'**. *Coeliac serology (anti-TTG antibodies)* - **Coeliac disease** is a potential cause of growth failure after the introduction of gluten, but it typically presents with **gastrointestinal symptoms** like abdominal pain or bloating. - It should be considered if nutritional assessment is normal or if **malabsorption** is suspected. *Sweat test for cystic fibrosis* - **Cystic fibrosis** usually presents with **respiratory symptoms** or **steatorrhea** (foul-smelling, oily stools) due to pancreatic insufficiency. - This is not the most appropriate initial step in a child and is usually screened for during the **newborn blood spot** test. *Thyroid function tests* - While **hypothyroidism** can cause poor growth, it is more commonly associated with a decline in **height velocity** rather than isolated weight faltering. - Developmental delay or **constipation** would also typically be present in a child with untreated hypothyroidism. *Full blood count and ferritin* - This is useful for identifying **anaemia**, which can be a consequence of poor intake or malabsorption, but doesn't identify the cause of growth failure itself. - It should be part of a second-line screen if **nutritional counseling** and dietary assessment fail to resolve the issue.
Question 133: A school nurse is asked to review a 6-year-old girl whose teacher reports that she frequently appears tired, wears dirty clothes, and often comes to school without lunch or appropriate clothing for the weather. The child's academic performance has declined. Her growth chart shows she has been following the 25th centile consistently. What type of child maltreatment does this scenario most likely represent?
- A. Physical abuse
- B. Emotional abuse
- C. Sexual abuse
- D. Neglect (Correct Answer)
- E. Fabricated or induced illness
Explanation: ***Neglect*** - **Neglect** is defined as the persistent failure to meet a child's **basic physical and psychological needs**, including food, clothing, and hygiene. - Key indicators in this case include **dirty clothes**, lack of **school lunch**, and inappropriate attire for the weather, which impact the child's academic performance and energy levels. *Physical abuse* - This involves **non-accidental physical injury** or harm, such as bruises, fractures, or burns, which are not described in this scenario. - There is no mention of visible **trauma** or unexplained injuries during the school nurse's review. *Emotional abuse* - Characterized by the persistent **emotional maltreatment** of a child, such as belittling, bullying, or terrorizing, leading to severe adverse effects on emotional development. - While neglect often has an emotional component, the primary findings here are physical manifestations of **unmet basic needs**. *Sexual abuse* - Involves forcing or enticing a child to take part in **sexual activities**, often presenting with behavioral changes, STIs, or genital trauma. - No signs of **age-inappropriate sexual knowledge** or physical symptoms related to sexual harm are mentioned. *Fabricated or induced illness* - Also known as **Munchausen syndrome by proxy**, where a caregiver fakes or causes symptoms in a child to seek medical attention. - This scenario shows **neglect of basic care** rather than the active fabrication of medical conditions or excessive healthcare seeking.
Question 134: A 30-month-old child is brought to the GP for a developmental review. The mother is concerned that the child is not yet talking in sentences. The child can say approximately 20 single words, follows simple one-step commands, plays alongside other children, can build a tower of 6 cubes, and runs well. What is the most appropriate management?
- A. Refer to speech and language therapy for assessment
- B. Reassure the mother that this is normal development and review at 3 years
- C. Request audiology assessment for hearing test (Correct Answer)
- D. Refer to community paediatrics for autism spectrum disorder assessment
- E. Advise waiting until age 3 years as boys develop language later
Explanation: ***Request audiology assessment for hearing test***- In any child presenting with **isolated language delay**, the first and most critical investigation is to **rule out hearing impairment**.- By **30 months**, a child should typically have 50+ words and use simple **two-word phrases**; since this child only has 20 words and no sentences, a formal audiological evaluation is the mandatory first step.*Reassure the mother that this is normal development and review at 3 years*- This management is inappropriate because the child is significantly behind the **developmental milestone** of joining words by age 2.- Delaying assessment risks missing the **critical window** for language acquisition and early intervention.*Refer to speech and language therapy for assessment*- While a referral to **Speech and Language Therapy (SLT)** will likely be necessary, it should ideally happen alongside or after **audiology**.- SLT cannot provide an accurate assessment of expressive or receptive language potential without knowing the child's **hearing status**.*Refer to community paediatrics for autism spectrum disorder assessment*- This referral is not yet indicated as the child shows age-appropriate **social play** (playing alongside others) and **gross/fine motor skills**.- **Autism spectrum disorder (ASD)** involves deficits in social communication and restricted interests, which are not described in this child’s profile.*Advise waiting until age 3 years as boys develop language later*- This is based on a **misconception**; while some variation exists, all children must meet minimum safety milestones for language development regardless of gender.- Waiting another 6 months before investigating an obvious **language delay** can lead to poorer educational and social outcomes.
Question 135: A 4-year-old boy presents to the emergency department with his father, who reports the child fell down stairs 2 hours ago. Examination reveals multiple bruises of varying colours on the trunk and upper arms, a swollen right forearm with tenderness, and the child appears withdrawn and avoids eye contact. X-ray confirms a transverse fracture of the right radius. Which aspect of this presentation is most concerning for non-accidental injury?
- A. The transverse nature of the radius fracture
- B. The 2-hour delay in seeking medical attention
- C. The presence of bruises of different ages in protected areas (Correct Answer)
- D. The child's withdrawn behaviour and poor eye contact
- E. The mechanism of injury being a fall down stairs
Explanation: ***The presence of bruises of different ages in protected areas*** - Multiple bruises of **varying colors** indicate injuries sustained at different times, which is highly suggestive of **recurrent trauma** or physical abuse. - Bruising on **protected soft-tissue areas** like the **trunk** and **upper arms** is a significant red flag, as accidental bruises in children usually occur over **bony prominences** such as the shins or forehead. *The transverse nature of the radius fracture* - A **transverse fracture** is common in accidental injuries, such as a direct blow or a fall, and is less specific for abuse than **metaphyseal corner fractures** or **spiral fractures**. - While any fracture in a young child requires scrutiny, the orientation of this specific fracture is not the most definitive sign of **non-accidental injury (NAI)**. *The 2-hour delay in seeking medical attention* - A **2-hour delay** is relatively short and may be logically explained by the time taken to assess the injury or arrange transport, making it a weaker indicator of NAI. - Significant delays (e.g., waiting until the next day for a major injury) are more concerning for **neglect** or an attempt to hide the mechanism of injury. *The child's withdrawn behaviour and poor eye contact* - **Withdrawn behavior** can be a non-specific response to **pain**, **fear** of the hospital environment, or a natural personality trait in a 4-year-old. - While behavioral changes can be associated with chronic abuse, they are considered secondary signs compared to the physical evidence of **multi-stage bruising**. *The mechanism of injury being a fall down stairs* - A **fall down stairs** is a common and plausible explanation for a limb fracture in a preschool-aged child. - This mechanism only becomes concerning if the **clinical findings** (like specific bruise patterns) are inconsistent with the force or trajectory described by the caregiver.
Question 136: A GP reviews a 6-month-old infant for developmental assessment. The parents report that the baby can roll from prone to supine, reaches for objects with both hands, and babbles using different consonant sounds. However, the infant does not yet have head control when pulled to sit. What is the most appropriate next step?
- A. Request urgent MRI brain scan
- B. Reassure parents this is normal development and review at 9 months
- C. Refer urgently to paediatrics for neurological assessment (Correct Answer)
- D. Advise physiotherapy exercises and review in 2 weeks
- E. Screen for developmental dysplasia of the hip
Explanation: ***Refer urgently to paediatrics for neurological assessment***- **Head control** when pulled to sit is a gross motor milestone expected by **4 to 5 months**; its absence at 6 months is a significant **developmental red flag**.- This specific **gross motor delay**, despite age-appropriate fine motor and communication skills, necessitates urgent specialist evaluation to investigate potential underlying conditions like **cerebral palsy** or **neuromuscular disorders**.*Request urgent MRI brain scan*- An **MRI brain scan** is an advanced diagnostic tool that should be ordered by a **paediatric specialist** after a thorough clinical and neurological examination.- It is not the initial step for a general practitioner; a clinical **neurological assessment** is required first to establish the indication for imaging.*Reassure parents this is normal development and review at 9 months*- The absence of **head control** by 6 months is **not normal development** and represents a significant delay that requires immediate attention.- Reassurance and delayed review are inappropriate, as they could delay early intervention for potentially serious **neurological pathologies**.*Advise physiotherapy exercises and review in 2 weeks*- While **physiotherapy** might be part of a management plan, it cannot replace a definitive **diagnostic assessment** to identify the cause of the delay.- A 2-week review is insufficient for evaluating a significant **neurological milestone failure** that has progressed beyond the expected age.*Screen for developmental dysplasia of the hip*- **Developmental dysplasia of the hip (DDH)** is characterized by hip instability or malformation, typically presenting with limited hip abduction or leg length discrepancy.- This condition is unrelated to the infant's lack of **head control**, which points towards a **neuromotor issue** rather than a skeletal one.
Question 137: A paediatric junior doctor attends safeguarding training on recognising patterns of bruising in children. Which statement about bruising in children and safeguarding concerns is correct?
- A. Bruising over bony prominences in a 3-year-old is highly specific for non-accidental injury
- B. Bruising in a non-mobile infant should always raise safeguarding concerns (Correct Answer)
- C. Mongolian blue spots are a form of bruising and indicate previous trauma
- D. Petechiae distributed over the whole body are typical of accidental injury
- E. Yellow bruises indicate acute trauma within the last 24 hours
Explanation: ***Bruising in a non-mobile infant should always raise safeguarding concerns***- Bruising in infants who are not yet **cruising** or walking (non-mobile) is extremely rare and highly suggestive of **non-accidental injury (NAI)**.- The medical mantra "**those who don't cruise rarely bruise**" highlights the clinical necessity of investigating any bruise in a young infant as a potential safeguarding issue.*Bruising over bony prominences in a 3-year-old is highly specific for non-accidental injury*- Bruising over **bony prominences** such as the shins, knees, and forehead is very common in active, mobile children and is usually **accidental**.- Non-accidental injuries are more likely to be found in **protected areas** like the ears, neck, torso, or upper arms.*Mongolian blue spots are a form of bruising and indicate previous trauma*- These are **congenital dermal melanocytosis**, which are flat, pigmented birthmarks commonly found on the lower back or buttocks of infants with darker skin tones.- They are present from **birth** and do not represent trauma; misidentifying them as bruises can lead to unnecessary safeguarding investigations.*Petechiae distributed over the whole body are typical of accidental injury*- Widespread **petechiae** are not typical of accidental injury and may indicate serious medical conditions like **meningococcal sepsis** or haematological disorders.- In a safeguarding context, localised petechiae (e.g., on the face or neck) can specifically indicate **suffocation** or **strangulation**.*Yellow bruises indicate acute trauma within the last 24 hours*- **Yellowing** of a bruise typically occurs during the later stages of resolution, usually appearing after **7 to 10 days** as haemoglobin breaks down.- Research indicates that **visual dating** of bruises based on colour is often inaccurate and should not be relied upon as a sole clinical indicator of timing.
Question 138: A practice nurse is reviewing immunisation records and notes that several children have crossed centiles on their growth charts. Which pattern of centile crossing on a growth chart is most likely to represent normal variation rather than pathology?
- A. A 6-month-old infant who has dropped from the 75th to the 25th centile for weight over 4 months
- B. A 2-year-old child whose height has risen from the 9th to the 75th centile over 12 months
- C. A 3-week-old breastfed infant who has dropped from the 50th to the 25th centile for weight (Correct Answer)
- D. A 4-year-old child whose weight has risen from the 50th to the 98th centile over 6 months
- E. A 7-year-old child whose height has dropped from the 50th to the 9th centile over 18 months
Explanation: ***A 3-week-old breastfed infant who has dropped from the 50th to the 25th centile for weight*** - In the first few weeks of life, infants often adjust their growth curve from their birth centile (which reflects the uterine environment) to one reflecting their **genetic potential**. This is particularly true for **breastfed infants** who may have an initial weight drop or slower gain. - A drop of one major centile space (e.g., from 50th to 25th) in the **first few weeks** is a common and usually **normal physiological variation**, especially as feeding patterns establish. *A 6-month-old infant who has dropped from the 75th to the 25th centile for weight over 4 months* - A drop of **two or more major centile spaces** (e.g., 75th to 25th) after the initial neonatal period (typically after 2-3 months) is a significant concern for **faltering growth** or **failure to thrive**. - This pattern warrants urgent investigation for underlying medical conditions such as **malabsorption**, **inadequate caloric intake**, or chronic disease. *A 2-year-old child whose height has risen from the 9th to the 75th centile over 12 months* - A rapid upward crossing of **height centiles** (e.g., from 9th to 75th) at this age is concerning for **accelerated growth** and is typically not a normal variation. - This pattern may indicate conditions such as **precocious puberty**, **growth hormone excess**, or certain genetic syndromes, requiring further endocrine evaluation. *A 4-year-old child whose weight has risen from the 50th to the 98th centile over 6 months* - A rapid increase in **weight centiles** to the **obesity range** (above 91st or 98th centile) in a short period suggests **excessive caloric intake** relative to energy expenditure, indicating **childhood obesity**. - This is a significant deviation from normal growth and increases the risk of metabolic and cardiovascular issues, requiring intervention. *A 7-year-old child whose height has dropped from the 50th to the 9th centile over 18 months* - A significant downward crossing of **height centiles** (e.g., 50th to 9th), especially after infancy, indicates **growth faltering** and is rarely a normal variation. - This pattern could suggest underlying conditions such as **growth hormone deficiency**, **hypothyroidism**, **chronic systemic illness** (e.g., inflammatory bowel disease), or nutritional deficiencies, warranting thorough investigation.
Question 139: A 12-month-old infant is reviewed at a routine health surveillance visit. The health visitor asks about developmental milestones. Which of the following gross motor skills would be expected to be achieved by a typically developing child at this age?
- A. Standing independently without holding on (Correct Answer)
- B. Running with good coordination
- C. Hopping on one foot
- D. Climbing stairs with alternating feet
- E. Walking independently without support
Explanation: ***Standing independently without holding on*** - By **12 months**, an infant typically achieves the ability to **stand alone** momentarily or for several seconds without support. - This milestone follows **cruising** and is a critical precursor to the development of stable, independent walking. *Running with good coordination* - This is an advanced gross motor skill that typically emerges between **18 to 24 months** of age. - A 12-month-old is still developing the **balance and muscle strength** required for basic gait, let alone coordinated running. *Hopping on one foot* - **Hopping on one foot** is a complex balance milestone usually attained around **4 years** of age. - It requires significant **vestibular maturation** and unilateral muscle strength far beyond the capability of a 1-year-old. *Climbing stairs with alternating feet* - A child usually starts to **climb stairs with alternating feet** at approximately **3 years** of age. - At 12 months, a child may only be able to **crawl up stairs**, as placing one foot per step requires advanced **bilateral coordination**. *Walking independently without support* - While many children begin to walk around their first birthday, the average range for **independent walking** is **12 to 15 months**. - Since not all typically developing children walk by exactly 12 months, **standing independently** is the more reliable expected milestone for this specific age.
Question 140: A 10-year-old girl is reviewed in clinic for short stature. Height is on the 0.4th centile, weight on the 9th centile. She has always been small but growth velocity has been normal. Both parents are short (father 162cm, mother 150cm). Bone age matches chronological age. She is otherwise well with normal examination findings. Thyroid function and coeliac screening are normal. Mid-parental height calculation places target centile range between 2nd and 25th centiles. Evaluating the need for further investigation, what is the most appropriate management?
- A. Commence growth hormone therapy as height is below the 2nd centile
- B. Arrange referral to paediatric endocrinology for growth hormone stimulation testing
- C. Request chromosomal analysis including karyotype to exclude Turner syndrome
- D. Provide reassurance, explain the diagnosis of familial short stature, and arrange annual growth monitoring (Correct Answer)
- E. Perform MRI pituitary to exclude structural causes of growth hormone deficiency
Explanation: ***Provide reassurance, explain the diagnosis of familial short stature, and arrange annual growth monitoring*** - The diagnosis is **familial short stature (FSS)** because the child’s height is consistent with her short parents, and she maintains a **normal growth velocity** despite being on the 0.4th centile. - A **bone age matching chronological age** is a hallmark of FSS, distinguishing it from constitutional delay where bone age would be significantly delayed. *Commence growth hormone therapy as height is below the 2nd centile* - **Growth hormone therapy** is not indicated for variants of normal growth like FSS when the **growth velocity** is normal and there is no biochemical deficiency. - Management is focused on **monitoring and reassurance** rather than medical intervention for genetically determined height centiles. *Arrange referral to paediatric endocrinology for growth hormone stimulation testing* - **GH stimulation testing** is unnecessary as the child has a **normal growth velocity**, which is the most sensitive clinical indicator of GH sufficiency. - Testing is reserved for children with **decelerating growth** or those significantly crossing centiles downwards, which is not the case here. *Request chromosomal analysis including karyotype to exclude Turner syndrome* - While Turner syndrome is a cause of short stature in girls, it typically presents with a **decline in growth velocity** and often other physical stigmata not seen in this healthy child. - The fact that the height centile is entirely explained by the **mid-parental height** makes a chromosomal abnormality highly unlikely. *Perform MRI pituitary to exclude structural causes of growth hormone deficiency* - **MRI of the pituitary** is only performed after biochemical tests confirm **growth hormone deficiency** to look for structural anomalies. - There are no symptoms of **midline defects** or neurological signs that would justify neuroimaging in a child with normal development and physiology.
