Pediatric Trauma Indian Medical PG Practice Questions and MCQs
Question 1: In splenic injury, conservative management is done in which of the following?
- A. Extreme pallor and hypotension
- B. Young patient (Correct Answer)
- C. Shattered spleen
- D. Hemodynamically unstable
Explanation: ***Young patient*** - **Conservative management** of splenic injury is often favored in **younger patients** due to their greater capacity for healing and the desire to preserve splenic function. - The risk of **overwhelming post-splenectomy infection (OPSI)** is higher in children, making splenic preservation a priority. *Extreme pallor and hypotension* - **Extreme pallor** and **hypotension** are signs of significant blood loss and **hemodynamic instability**, which typically necessitate surgical intervention. - **Conservative management** is usually contraindicated in such cases as the patient is actively bleeding. *Shattered spleen* - A **shattered spleen** indicates a severe, often **grade IV or V** splenic injury, where the spleen is extensively fragmented. - This level of injury is associated with uncontrollable bleeding and almost always requires **splenectomy**. *Hemodynamically unstable* - **Hemodynamic instability**, characterized by persistent hypotension, tachycardia, or inadequate organ perfusion, is a **contraindication** to conservative management. - Patients who are **hemodynamically unstable** need immediate surgical exploration to control bleeding.
Question 2: Which of the following is a characteristic feature of Battered Baby Syndrome (Non-Accidental Injury)?
- A. Stab injury
- B. Firearm injury
- C. Bruises of varying ages (Correct Answer)
- D. None of the options
Explanation: ***Bruises of varying ages*** - The presence of bruises at **different stages of healing** is a hallmark indicator of **non-accidental trauma** or Battered Baby Syndrome, as it suggests repeated injuries occurring over time rather than a single incident. - **Forensic significance**: Fresh bruises (red/purple) alongside older bruises (yellow/green/brown) indicate multiple episodes of trauma, which is inconsistent with the caregiver's explanation of a single accidental event. - Other classic features include fractures (especially metaphyseal/corner fractures, rib fractures), subdural hematomas, retinal hemorrhages, and injuries in protected body areas. *Stab injury* - While a stab injury represents severe trauma requiring forensic investigation, it is **not characteristic** of the typical presentation pattern of Battered Baby Syndrome. - Stab wounds indicate a specific violent act rather than the pattern of **repeated blunt force trauma** that defines the syndrome. - Battered Baby Syndrome classically involves injuries from shaking, hitting, or blunt trauma rather than penetrating injuries. *Firearm injury* - A firearm injury is a distinct acute traumatic event that does not represent the **chronic, repetitive abuse pattern** seen in Battered Baby Syndrome. - Such injuries are typically isolated incidents rather than part of ongoing physical abuse with varied injury ages. - The syndrome is characterized by multiple injuries at different healing stages from repeated episodes, not single penetrating trauma. *None of the options* - This option is incorrect because "bruises of varying ages" is a **well-established forensic indicator** for diagnosing Battered Baby Syndrome in medical literature and practice. - The presence of injuries at multiple stages of healing is one of the most important diagnostic features that raises suspicion for non-accidental injury in pediatric forensic medicine.
Question 3: A traumatic injury to an 8-year-old child, with marking of a rickshaw tyre found on the body, is an example of -
- A. Pattern bruises (Correct Answer)
- B. Imprint abrasion
- C. Percolated bruise
- D. Contusion
Explanation: ***Pattern bruises*** - This scenario describes **pattern bruising**, where the **shape of the injuring object** (rickshaw tyre) is clearly visible on the body. - Pattern bruises are indicative of severe trauma and provide crucial **forensic evidence** about the **weapon or mechanism of injury**. - This is the **specific forensic medicine term** for bruises that retain the characteristic pattern of the causative object. *Imprint abrasion* - An imprint abrasion occurs when the **surface features of an object are scraped onto the skin**, leaving a superficial injury with disruption of the epidermis. - This typically involves **scraping or rubbing** of the skin surface, whereas the question describes **marking** on the body, which in forensic context refers to a bruise (subcutaneous hemorrhage) rather than a superficial abrasion. *Percolated bruise* - A percolated bruise refers to a bruise where the **blood has spread extensively** through the tissue planes, often making its initial impact site difficult to discern. - The pattern becomes **diffuse and indistinct**, which is the opposite of the clear tyre marking described in the question. *Contusion* - A contusion is the **general medical term** for a bruise - any blunt force injury causing damaged capillaries and blood vessels with subcutaneous bleeding. - While the injury IS technically a contusion, **"pattern bruise" is the more specific and correct forensic medicine terminology** that describes a contusion with the distinctive shape of the causative object. - In forensic medicine, specificity matters - we use "pattern bruise" to immediately convey that the injury has evidential value showing the weapon's characteristics.
Question 4: What is the correct sequence of management in a patient who presents to the casualty with an RTA? 1. Cervical spine stabilization 2. Intubation 3. IV cannulation 4. CECT
- A. 2,1,4,3
- B. 1,3,2,4
- C. 2,1,3,4
- D. 1,2,3,4 (Correct Answer)
Explanation: ***1,2,3,4*** - This sequence follows the **ATLS (Advanced Trauma Life Support)** protocol, prioritizing immediate life threats in order. - **Cervical spine stabilization** is the **first action upon patient contact** to prevent secondary neurological injury in any trauma patient. - **Airway management (intubation)** is then performed **with maintained in-line c-spine stabilization** - these occur nearly simultaneously but c-spine protection is instituted first. - **IV cannulation (circulation)** follows to establish vascular access for resuscitation and medications. - **CECT (imaging)** is performed last, once the patient is stabilized after addressing immediate life threats. - This follows the **ATLS Primary Survey: Airway (with c-spine protection) → Breathing → Circulation → Disability → Exposure**. *2,1,4,3* - This incorrectly places intubation **before** cervical spine stabilization is initiated. - In ATLS, **c-spine protection must be applied immediately upon patient contact** before any airway manipulation. - Delaying IV cannulation until after CECT is inappropriate as circulatory access is critical for early resuscitation. *1,3,2,4* - While this correctly starts with cervical spine stabilization, it incorrectly places **IV cannulation before intubation**. - In the ATLS primary survey, **Airway comes before Circulation** - securing the airway takes priority over establishing IV access. - This sequence could delay critical airway management in a patient with respiratory compromise. *2,1,3,4* - This sequence places **intubation before cervical spine stabilization**, which violates ATLS principles. - **C-spine stabilization must be the first action** upon approaching any trauma patient to prevent secondary spinal cord injury. - While intubation with in-line stabilization is possible, the c-spine protection must be instituted first, not after beginning airway manipulation.
Question 5: In a radiograph of suspected non-accidental injury, which of the following fractures is LEAST specific for child abuse?
- A. Metaphysis corner fracture
- B. Costochondral & rib junction fracture
- C. Parietal bone fracture (Correct Answer)
- D. Sternal fracture
Explanation: ***Parietal bone fracture*** - While **parietal bone fractures** are commonly seen in both accidental and non-accidental pediatric head trauma, they are **less specific for child abuse** compared to the classic skeletal injuries listed below. - Isolated skull fractures, particularly **simple linear parietal fractures**, can result from accidental falls and require additional clinical context (age, mechanism, associated injuries) to determine if abuse is suspected. - Complex, multiple, or depressed skull fractures are more concerning, but a simple parietal fracture alone is less diagnostic than the pathognomonic fractures of NAI. *Metaphyseal corner fracture* - Also known as **"bucket handle"** or **"corner" fractures**, these are **highly specific and virtually pathognomonic** for **non-accidental injury** in infants and young children. - They result from violent **shaking, twisting, or pulling forces** applied to the extremities, causing avulsion at the metaphyseal-epiphyseal junction. - These fractures are rarely seen in accidental trauma. *Costochondral & rib junction fracture* - **Posterior rib fractures** and **costochondral junction fractures** are **highly specific for NAI** in infants. - They result from **anteroposterior chest compression** during forceful squeezing or gripping of the thorax. - Accidental rib fractures in children are rare due to chest wall elasticity, making these fractures particularly suspicious. *Sternal fracture* - **Sternal fractures** are extremely rare in children due to the **flexibility of the pediatric sternum** and chest wall. - Their presence, especially without a history of **severe high-impact trauma** (e.g., motor vehicle collision), is **highly suspicious for non-accidental injury**. - Often result from direct forceful blows or severe compression injuries.
Question 6: An unconscious child is brought to the casualty. What is the correct sequence of the management?
- A. Circulation, Airway, Breathing
- B. Breathing, Circulation, Airway
- C. Circulation, Breathing, Airway
- D. Airway, Breathing, Circulation (Correct Answer)
Explanation: ***Airway, Breathing, Circulation*** - The **ABC sequence** is the cornerstone of pediatric resuscitation as per **PALS (Pediatric Advanced Life Support) guidelines** - In an unconscious child, a patent **airway** is the absolute first priority - without this, no oxygen can reach the lungs regardless of breathing effort - Once airway patency is ensured, **breathing** must be assessed and supported to provide adequate ventilation and oxygenation - Only after securing airway and breathing should **circulation** be addressed, as effective circulation without oxygenation is futile - This sequence prevents **hypoxic brain injury**, which can occur within 4-6 minutes of oxygen deprivation *Circulation, Airway, Breathing* - This violates the fundamental **ABC principle** of emergency management - Prioritizing **circulation** before establishing a patent **airway** means attempting to circulate deoxygenated blood - Without airway patency, any circulatory support will fail to deliver oxygen to vital organs, leading to **irreversible hypoxic damage** - In pediatric emergencies, respiratory failure is more common than primary cardiac arrest, making airway management even more critical *Breathing, Circulation, Airway* - Attempting to support **breathing** before securing the **airway** is physiologically ineffective - An obstructed airway prevents air entry despite breathing efforts or bag-mask ventilation attempts - This sequence can lead to **gastric distension, aspiration**, and worsening hypoxia - Delays in airway management increase the risk of **cardiac arrest** from prolonged hypoxemia *Circulation, Breathing, Airway* - This sequence dangerously delays **airway management**, the most time-critical intervention - In an unconscious child, airway obstruction from tongue falling back or secretions is common and immediately life-threatening - Without a patent airway, neither breathing support nor circulatory measures can prevent **brain death** from anoxia - Following this sequence contradicts all **international resuscitation guidelines** (PALS, AHA, ERC)
Question 7: What is the maintenance fluid requirement in a 6 kg child ?
- A. 240 ml/day
- B. 600 ml/day (Correct Answer)
- C. 300 ml/day
- D. 1200 ml/day
Explanation: **600 ml/day** - The **Holliday-Segar formula** is used to calculate maintenance fluid requirements. For the first 10 kg of body weight, the requirement is 100 ml/kg/day. - For a 6 kg child, the calculation is 6 kg * 100 ml/kg/day = **600 ml/day**. *240 ml/day* - This value is significantly **lower** than the recommended maintenance fluid for a 6 kg child, which would lead to **dehydration**. - It does not align with the standard Holliday-Segar formula for this weight. *300 ml/day* - This amount is **insufficient** for a 6 kg child's daily maintenance fluid needs and would risk **hypovolemia**. - It represents roughly half of the calculated requirement based on standard pediatric guidelines. *1200 ml/day* - This volume is significantly **higher** than the maintenance fluid requirement for a 6 kg child and could lead to **fluid overload** and hyponatremia. - This calculation might be appropriate for a much heavier child or in situations of increased fluid loss.
Question 8: According to the Lund and Browder chart, what percentage of total body surface area (TBSA) does the head and face represent in a 1-year-old child?
- A. 16%
- B. 10%
- C. 19% (Correct Answer)
- D. 13%
Explanation: ***19%*** - The **Lund and Browder chart** accounts for age-related variations in body proportions, assigning a larger percentage of **total body surface area (TBSA)** to the head in infants and young children. - For a **1-year-old child**, the head and face are estimated to represent approximately **19% TBSA**, which decreases with age as the body proportions change. *16%* - While 16% is a value sometimes associated with the head, it is not the accurate percentage for a **1-year-old child** according to the **Lund and Browder chart**. - This percentage is typically closer to that of an **older child** or adult's head, as body proportions change over time. *10%* - **10% TBSA** is far too low for the head and face of a **1-year-old child** as per the Lund and Browder chart. - This value is usually associated with areas like the **arms** in children or the head of an **adult** in some simpler TBSA estimation methods. *13%* - **13% TBSA** is an underestimation for the head and face of a **1-year-old child** when using the **Lund and Browder chart**. - The large relative size of an infant's head means it contributes a significantly higher percentage to their **total body surface area**.
Question 9: Which of the following statements about the ABCDE approach in pediatric Advanced Life Support (PALS) is incorrect?
- A. Dehydration is a component of the ABCDE approach. (Correct Answer)
- B. Airway management is essential in PALS.
- C. Breathing assessment is part of the ABCDE approach.
- D. Circulation is a critical component of the ABCDE approach.
Explanation: ***Dehydration is a component of the ABCDE approach.*** - The **ABCDE approach** in PALS focuses on **Airway, Breathing, Circulation, Disability, and Exposure**, which are immediate life threats. - While dehydration is a crucial clinical concern in children, it's a **diagnostic consideration** and management target, not a primary component of the initial rapid assessment categories (A, B, C, D, E) themselves. - Dehydration may affect circulation (C) but is not itself a separate component of the ABCDE framework. *Airway management is essential in PALS.* - **Airway** is the first step in the ABCDE approach, focusing on ensuring a **patent and protected airway** to allow for effective ventilation. - **Airway management** is critical in pediatric resuscitation to prevent respiratory arrest and optimize oxygen delivery. *Breathing assessment is part of the ABCDE approach.* - **Breathing** is the second step, involving the assessment of **respiratory rate, effort, breath sounds, and oxygen saturation**. - Effective breathing is vital for adequate **oxygenation and ventilation**, and addressing breathing problems is a key part of PALS. *Circulation is a critical component of the ABCDE approach.* - **Circulation** is the third step, involving the assessment of **heart rate, blood pressure, capillary refill time, and peripheral perfusion**. - **Circulatory assessment** helps identify shock or cardiac arrest, which require immediate intervention. - The complete ABCDE also includes **Disability** (neurological status assessment using AVPU or GCS) and **Exposure** (full examination while preventing hypothermia).
Question 10: At what rate should dopamine be administered for inotropic support in a severely dehydrated child?
- A. 0.1-0.5 microgram/kg/min
- B. 1-5 microgram/kg/min (Correct Answer)
- C. 1-5 mg/kg/min
- D. 10-15 mg/kg/min
Explanation: ***1-5 microgram/kg/min*** - This dosage range of **dopamine** primarily targets **beta-1 adrenergic receptors**, leading to **increased myocardial contractility** (inotropic effect) and improved cardiac output. - It is appropriate for managing **hypotension** and poor perfusion in a severely dehydrated child after initial **fluid resuscitation** has been attempted but was insufficient. *0.1-0.5 microgram/kg/min* - This very low dose range of dopamine primarily stimulates **dopaminergic receptors** in the renal and mesenteric vascular beds. - Its main effect is **vasodilation** in these areas, which increases blood flow to the kidneys and gut, but it provides minimal to no **inotropic support**. *1-5 mg/kg/min* - This dosage is significantly too high, as it is in milligrams rather than micrograms. - Administering dopamine at this rate would lead to severe **toxicity**, including profound **tachycardia**, ventricular arrhythmias, and extreme **vasoconstriction**. *10-15 mg/kg/min* - This dopamine dosage is also excessively high, again due to being in milligrams per minute rather than micrograms per minute. - Such a dose would be **lethal**, causing catastrophic cardiovascular collapse due to overwhelming **alpha-adrenergic stimulation** and severe arrhythmias.
