Question 51: A 6-year-old girl with known asthma on beclometasone 200 micrograms twice daily presents to the emergency department with acute breathlessness following exposure to a cat at a friend's house. She is speaking in words only, has a respiratory rate of 40 breaths per minute, heart rate of 135 beats per minute, and oxygen saturation of 90% on room air. There is widespread wheeze with good air entry. She has received 3 doses of back-to-back nebulised salbutamol with ipratropium bromide, high-flow oxygen, and oral prednisolone 30 mg. After 1 hour, her oxygen saturation has improved to 95% on 6 litres oxygen, respiratory rate is 32, and she can speak in short sentences. What is the most appropriate next management step?
A. Discharge home with increased inhaled corticosteroid dose
B. Continue hourly nebulised salbutamol and reassess
C. Admit for observation with regular inhaled bronchodilators (Correct Answer)
D. Administer intravenous magnesium sulphate
E. Arrange urgent PICU review
Explanation: ***Admit for observation with regular inhaled bronchodilators***
- The patient initially presented with **severe acute asthma** (SpO2 90% on room air, speaking in words only) and, while improving, still requires **supplemental oxygen** (95% on 6L O2) and remains symptomatic (RR 32, speaking in short sentences), necessitating inpatient monitoring.
- BTS/SIGN guidelines for acute asthma in children suggest admission for those who require **oxygen therapy** to maintain saturation or fail to achieve a sustained response to initial emergency department treatment, or have significant ongoing symptoms.
*Discharge home with increased inhaled corticosteroid dose*
- Discharge is inappropriate as the patient still requires **supplemental oxygen** (6L O2) and has not achieved stability (e.g., SpO2 ">="94% on room air) and resolution of significant symptoms.
- A child should only be considered for discharge once they are stable on **4-hourly inhaled bronchodilators**, have no clinical signs of respiratory distress, and are maintaining adequate oxygen saturation on **room air**.
*Continue hourly nebulised salbutamol and reassess*
- While the patient showed initial improvement with back-to-back nebulizers, continuing hourly nebulised salbutamol without a structured inpatient plan indicates ongoing severe disease and is not a definitive next step for a patient showing partial improvement.
- For a patient who has partially improved but still requires oxygen and has persistent symptoms, the focus shifts to a period of observation with **regular (e.g., 4-hourly) bronchodilators** rather than just repeating hourly doses indefinitely in the ED.
*Administer intravenous magnesium sulphate*
- **Intravenous magnesium sulphate** is typically reserved for children with **life-threatening asthma** or those with **severe acute asthma** who show an inadequate response to initial bronchodilator and steroid therapy.
- This patient is showing significant clinical improvement (SpO2 95% on 6L O2, speaking in sentences, reduced RR), so advancing to **IV magnesium** is not currently indicated.
*Arrange urgent PICU review*
- **PICU review** is indicated for patients with **life-threatening features** (e.g., silent chest, exhaustion, hypotension, rapidly deteriorating despite maximal therapy) or those who are unresponsive to treatment.
- This child is clinically improving, and while not fully recovered, her current status does not meet the criteria for **life-threatening asthma** requiring intensive care at this stage.
Question 52: A 14-month-old child presents with a 24-hour history of fever to 38.7°C and increasing irritability. The parents report the child has been pulling at their right ear. On examination, the child is alert but distressed. Temperature is 38.5°C, heart rate is 135 beats per minute, respiratory rate is 32 breaths per minute, and capillary refill time is less than 2 seconds. Otoscopy of the right ear reveals a bulging, erythematous tympanic membrane with loss of normal landmarks. The left ear appears normal. What is the most appropriate initial management?
A. Prescribe immediate antibiotic therapy with amoxicillin
B. Advise watchful waiting with regular paracetamol and review if symptoms worsen
C. Prescribe delayed antibiotic prescription to be used if no improvement in 48-72 hours (Correct Answer)
D. Refer urgently to ENT for myringotomy
E. Prescribe topical antibiotic ear drops
Explanation: ***Prescribe delayed antibiotic prescription to be used if no improvement in 48-72 hours***
- In a child older than 6 months with **unilateral acute otitis media (AOM)** and no otorrhoea, a **back-up (delayed) antibiotic** strategy is recommended to reduce unnecessary antimicrobial use.
- Most cases of AOM are self-limiting; the delayed prescription serves as a **safety net** if symptoms fail to improve or worsen after the initial 2-3 days.
*Prescribe immediate antibiotic therapy with amoxicillin*
- Immediate antibiotics are typically reserved for children under 2 years with **bilateral AOM**, those with **systemic distress**, or children presenting with **otorrhoea**.
- This child presents with unilateral disease and is **systemically well**, making immediate therapy unnecessary as the first-line approach.
*Advise watchful waiting with regular paracetamol and review if symptoms worsen*
- While **analgesia** is essential for managing pain (distress and ear pulling), a pure 'no antibiotic' strategy may be less suitable for a child **under 2 years** than a delayed prescription.
- NICE guidelines favor providing a **contingency plan** (delayed script) for younger children to ensure they receive treatment if natural resolution does not occur.
*Refer urgently to ENT for myringotomy*
- **Myringotomy** is a surgical procedure reserved for complications such as **mastoiditis**, facial nerve palsy, or recurrent refractory cases.
- It is not indicated for an initial presentation of **uncomplicated acute otitis media** in a stable child.
*Prescribe topical antibiotic ear drops*
- **Topical antibiotics** are ineffective for AOM because the infection is localized behind an **intact tympanic membrane** where drops cannot reach.
- Topical therapy is only indicated if there is a **perforation** with discharge (Chronic Suppurative Otitis Media) or for Otitis Externa.
Question 53: A 12-year-old boy with poorly controlled asthma is currently on fluticasone 500 micrograms twice daily via metered dose inhaler and spacer, plus salbutamol as needed. He experiences symptoms requiring salbutamol 4-5 times per week and wakes at night with cough approximately twice per month. His inhaler technique is good and adherence is confirmed. According to BTS/SIGN guidelines, what is the most appropriate next step to optimize his asthma management?
A. Add long-acting muscarinic antagonist (LAMA) such as tiotropium
B. Add long-acting beta-agonist (LABA) such as salmeterol (Correct Answer)
C. Add leukotriene receptor antagonist (LTRA) such as montelukast
D. Increase inhaled corticosteroid to fluticasone 1000 micrograms twice daily
E. Add oral theophylline
Explanation: ***Add long-acting beta-agonist (LABA) such as salmeterol***- For children aged **12 and over**, BTS/SIGN guidelines follow the adult pathway, where **Step 3** involves adding a **LABA** to an inhaled corticosteroid (ICS) to manage persistent symptoms.- This patient remains symptomatic (night waking and frequent SABA use) on **moderate-dose ICS**, making the addition of a LABA the most effective next step to improve clinical control.*Add long-acting muscarinic antagonist (LAMA) such as tiotropium*- **LAMA** therapy is generally reserved for **Step 4** (persistent poor control) if the combination of ICS and LABA is insufficient.- It is not the preferred first-line add-on therapy for a patient currently only on **ICS monotherapy**.*Add leukotriene receptor antagonist (LTRA) such as montelukast*- Although **LTRAs** are added at Step 3 for children aged **5-11**, the pathway for those **12 and older** prioritizes LABA as the initial add-on.- LTRA would typically be considered if **LABA treatment fails** or if there is a specific clinical preference, but it is not the primary recommendation here.*Increase inhaled corticosteroid to fluticasone 1000 micrograms twice daily*- Increasing the **ICS dose** beyond a moderate level is generally less effective for symptom control than adding a **LABA**.- High doses of ICS (e.g., 2000 mcg/day total) increase the risk of systemic side effects without offering the **bronchodilatory benefits** of a LABA.*Add oral theophylline*- **Theophylline** is considered a fourth-line option or later due its narrow **therapeutic index** and significant side-effect profile.- It requires blood level **monitoring** and is only indicated when more effective therapies like LABAs have been optimized.
Question 54: A 10-month-old infant born at 28 weeks gestation with chronic lung disease of prematurity presents with a 3-day history of worsening cough, increased work of breathing, and reduced feeding. Temperature is 37.4°C, respiratory rate is 70 breaths per minute, heart rate is 165 beats per minute, and oxygen saturation is 88% on room air. On examination, there is severe subcostal and intercostal recession, nasal flaring, bilateral fine crackles, and expiratory wheeze. The infant appears tired. What is the most concerning clinical feature indicating need for urgent intervention?
A. History of chronic lung disease of prematurity
B. Respiratory rate of 70 breaths per minute
C. Oxygen saturation of 88% on room air
D. Appearance of tiredness with severe recession (Correct Answer)
E. Bilateral fine crackles and wheeze
Explanation: ***Appearance of tiredness with severe recession***
- An infant who appears **tired** or **exhausted** while demonstrating severe respiratory effort (recession) is showing signs of **impending respiratory failure** and muscle fatigue.
- This is a pre-terminal clinical feature that necessitates immediate senior review and potential **Paediatric Intensive Care (PICU)** involvement for mechanical ventilation or advanced support.
*History of chronic lung disease of prematurity*
- While this provides critical context and identifies the infant as **high risk** for severe bronchiolitis, it is a background risk factor rather than a dynamic clinical sign.
- It helps predict a potentially severe course but is not as immediately alarming as the physical sign of **respiratory exhaustion**.
*Respiratory rate of 70 breaths per minute*
- **Tachypnoea** is a standard feature of acute bronchiolitis and reflects increased work of breathing in response to **bronchiolar obstruction**.
- Although 70 bpm is high, it is a marker of compensation; the transition to **exhaustion** (appearing tired) is a more critical indicator of failing compensation.
*Oxygen saturation of 88% on room air*
- This level of **hypoxia** is concerning and typically warrants **supplemental oxygen** therapy according to guidelines.
- Hypoxia can often be corrected with low-flow oxygen, whereas **exhaustion** indicates the mechanical failure of the respiratory pump, which is more difficult to manage.
*Bilateral fine crackles and wheeze*
- These are characteristic physical findings in **bronchiolitis** caused by inflammation, mucus, and airway narrowing.
- While they confirm the diagnosis and severity, they do not carry the same urgent **prognostic weight** as the infant's overall level of fatigue and effort.
Question 55: A 2-year-old girl with recurrent viral-induced wheeze is reviewed in the paediatric clinic. Her mother reports that she has episodes of cough and wheeze approximately every 6-8 weeks, usually triggered by colds. Between episodes she is completely well with no symptoms. Episodes typically last 5-7 days and respond to salbutamol inhaler. She has had 4 episodes requiring healthcare assessment in the past year but no hospital admissions. There is no family history of atopy. What is the most appropriate management plan?
B. Continue as-needed salbutamol and provide parent-initiated oral prednisolone for acute episodes (Correct Answer)
C. Commence regular montelukast
D. Continue as-needed salbutamol only with safety-netting advice
E. Commence regular long-acting beta-agonist (salmeterol) with salbutamol as needed
Explanation: ***Continue as-needed salbutamol and provide parent-initiated oral prednisolone for acute episodes***
- This child presents with **episodic viral wheeze**, characterized by wheezing episodes strictly triggered by viruses with an **asymptomatic interval** between episodes.
- For children with frequent (e.g., >3 in 12 months) or severe episodes requiring healthcare visits, providing **parent-initiated oral prednisolone** for acute episodes can reduce their severity and the need for further medical assessment.
*Commence regular low-dose inhaled corticosteroid (beclometasone 100 micrograms twice daily)*
- **Inhaled corticosteroids (ICS)** are generally ineffective for **pure episodic viral wheeze** as there is no underlying persistent airway inflammation between viral infections.
- ICS are primarily indicated for **multitrigger wheeze** or asthma, where symptoms like nocturnal cough or exercise-induced wheeze occur even in the absence of viral infections.
*Commence regular montelukast*
- While **leukotriene receptor antagonists (LTRAs)** like montelukast can be considered for viral-induced wheeze, they are typically used if there are features of **atopy** or if simpler measures like acute oral steroids are not sufficient.
- Given the child's frequent healthcare visits, initiating **oral steroids** for acute exacerbations is a more targeted and effective approach for immediate symptom control and reducing disease burden.
*Continue as-needed salbutamol only with safety-netting advice*
- Maintaining **as-needed salbutamol** alone is suitable for infrequent, mild episodes of viral-induced wheeze.
- However, this child's history of **four healthcare assessments** in the past year indicates that this management strategy is insufficient and requires **escalation** to prevent future severe episodes.
*Commence regular long-acting beta-agonist (salmeterol) with salbutamol as needed*
- **Long-acting beta-agonists (LABA)** such as salmeterol are not indicated for **episodic viral wheeze** and should never be used as monotherapy in children.
- LABAs are part of the **stepwise management of asthma** and are typically added to a regimen that already includes inhaled corticosteroids, not as a standalone treatment for viral-induced wheeze.
Question 56: An 8-month-old infant is brought to the emergency department with a 6-hour history of fever to 39.1°C and one episode of vomiting. The infant appears unwell, with poor eye contact and weak cry. Temperature is 38.9°C, heart rate is 170 beats per minute, respiratory rate is 45 breaths per minute, capillary refill time is 3 seconds, and blood pressure is 75/40 mmHg. On examination, the anterior fontanelle is slightly full. There is no rash or respiratory distress. Blood tests show white cell count 18.2 × 10⁹/L with neutrophilia, CRP 87 mg/L. Which investigation should be performed immediately before starting empirical antibiotic therapy?
A. Blood cultures followed by lumbar puncture (Correct Answer)
B. Urine microscopy and culture via clean catch method
C. CT head to exclude intracranial pathology
D. Chest radiograph
E. Rapid antigen test for common viruses
Explanation: ***Blood cultures followed by lumbar puncture***
- This infant presents with **red flags for sepsis** and **meningitis**, including poor eye contact, weak cry, tachycardia, prolonged capillary refill time, low blood pressure, and a **slightly full anterior fontanelle**.
- **Blood cultures** are vital for identifying systemic pathogens, and a **lumbar puncture** is crucial for diagnosing meningitis, both of which must be performed before starting empirical antibiotics to ensure diagnostic accuracy.
*Urine microscopy and culture via clean catch method*
- While **urinary tract infection (UTI)** can cause fever, it does not explain the **full fontanelle** or the systemic signs of **shock** observed in this critically unwell infant.
- Obtaining a clean catch urine can be time-consuming and would inappropriately delay urgent investigations for more life-threatening conditions like meningitis or sepsis.
*CT head to exclude intracranial pathology*
- A **CT head** is not typically indicated before a lumbar puncture in an infant without focal neurological deficits or signs of impending brain herniation.
- Performing a CT scan would cause a dangerous **delay in the administration of life-saving antibiotics** for suspected bacterial meningitis, which is a medical emergency.
*Chest radiograph*
- The infant does not present with primary **respiratory symptoms** such as significant cough or focal lung signs to prioritize a chest radiograph.
- A **chest X-ray** would not directly aid in diagnosing the immediate life-threatening conditions like **sepsis** or **meningitis** suggested by the clinical presentation.
*Rapid antigen test for common viruses*
- While viral infections are common, the infant's **toxic appearance**, **neutrophilia**, and **elevated CRP** are highly suggestive of a **serious bacterial infection**, requiring urgent intervention.
- A **positive viral test** does not exclude a co-existing **serious bacterial infection (SBI)**, and relying on it would delay critical management for sepsis or meningitis.
Question 57: A 3-year-old boy presents with a 5-day history of persistent fever ranging from 38.8-40.3°C. He has been irritable with reduced appetite but is taking fluids. On examination, he has bilateral non-purulent conjunctival injection, cracked red lips, a polymorphous rash on his trunk, and cervical lymphadenopathy with one node measuring 2 cm. His hands and feet appear erythematous and slightly swollen. Heart sounds are normal with no murmur. Which investigation result would most strongly support the suspected diagnosis?
A. Positive anti-streptolysin O titre
B. Elevated platelet count of 550 × 10⁹/L (Correct Answer)
C. Positive blood cultures for Staphylococcus aureus
D. Elevated serum IgE levels
E. Positive Epstein-Barr virus serology
Explanation: ***Elevated platelet count of 550 × 10⁹/L***- This child meets the clinical criteria for **Kawasaki disease**, presenting with fever for 5 days, **conjunctival injection**, **cracked lips**, **polymorphous rash**, **lymphadenopathy**, and **extremity changes**.- **Thrombocytosis** (platelet count >450 × 10⁹/L) is a classic supportive finding that typically occurs in the **subacute phase** (second week) of the illness.*Positive anti-streptolysin O titre*- This finding indicates a recent **Group A Streptococcus** infection and is associated with **Rheumatic Fever** or **Scarlet Fever**.- While Scarlet Fever presents with a rash and strawberry tongue, it does not typically cause the **non-purulent conjunctivitis** characteristic of Kawasaki disease.*Positive blood cultures for Staphylococcus aureus*- **Staphylococcal Toxic Shock Syndrome** can mimic Kawasaki disease but would usually present with **hypotension** and more rapid clinical deterioration.- Kawasaki disease is an **idiopathic systemic vasculitis**, so blood cultures are characteristically **negative**.*Elevated serum IgE levels*- High IgE levels are typically associated with **atopic conditions** or specific immunodeficiencies like **Job syndrome**.- This lab result does not serve as a diagnostic or supportive marker for the systemic inflammation seen in **Kawasaki disease**.*Positive Epstein-Barr virus serology*- **Infectious mononucleosis** can cause fever, rash, and lymphadenopathy, but it is typically associated with **exudative pharyngitis** and **splenomegaly**.- EBV does not cause the specific **mucocutaneous manifestations** like cracked lips and hand/foot edema seen in this patient.
Question 58: What is the recommended dose of oral prednisolone for the treatment of acute asthma exacerbation in children aged 2-5 years according to current BTS/SIGN guidelines?
A. 10-20 mg once daily for 5 days
B. 10 mg once daily for 3 days
C. 20 mg once daily for 3 days (Correct Answer)
D. 1-2 mg/kg once daily for 3-5 days
E. 0.5 mg/kg twice daily for 3 days
Explanation: ***20 mg once daily for 3 days***
- According to **BTS/SIGN guidelines**, the standard dose for children aged **2-5 years** during an acute asthma exacerbation is **20 mg** of prednisolone.
- This dosage is typically administered for a duration of **3 days**, although it can be extended if the patient has not recovered.
*10 mg once daily for 3 days*
- This lower dose of **10 mg** is the recommendation for children **under 2 years** of age.
- Using this dose for a 3-year-old would result in **sub-therapeutic** treatment according to standard national protocols.
*1-2 mg/kg once daily for 3-5 days*
- While **weight-based dosing** is common in general pediatrics, the **BTS/SIGN guidelines** prioritize simplified **age-based dosing** for acute asthma.
- A total dose of **20 mg** is preferred over calculated ranges to ensure rapid and standardized delivery of steroid therapy.
*0.5 mg/kg twice daily for 3 days*
- Prednisolone is traditionally administered as a **single morning dose** to minimize the risk of **adrenal suppression** and insomnia.
- **Twice-daily** regimens are not standard for acute asthma management in the outpatient or emergency setting for this age group.
*10-20 mg once daily for 5 days*
- The **BTS/SIGN guidelines** specifically state a fixed dose of **20 mg** for the 2-5 age group, rather than a range starting at 10 mg.
- While a **5-day course** is acceptable if recovery is slow, the initial guideline recommendation emphasizes a **3-day course** as usually sufficient.
Question 59: A 5-year-old boy with asthma presents to the emergency department with wheeze and breathlessness that started 4 hours ago. He is currently on beclometasone 200 micrograms twice daily via a spacer device. On examination, he can speak in short phrases, respiratory rate is 35 breaths per minute, heart rate is 125 beats per minute, and oxygen saturation is 94% on room air. There is moderate chest wall recession with widespread polyphonic wheeze. His peak expiratory flow is 55% of his predicted best. Which severity classification best describes this acute asthma exacerbation?
A. Moderate acute asthma (Correct Answer)
B. Severe acute asthma
C. Life-threatening asthma
D. Near-fatal asthma
E. Mild acute asthma
Explanation: ***Moderate acute asthma***
- The patient's **peak expiratory flow (PEF) of 55%** of predicted best falls squarely within the 50-75% range for moderate asthma exacerbations.
- Clinical signs like being able to **speak in short phrases**, an oxygen saturation of **94%**, and **moderate chest wall recession** are also consistent with a moderate classification.
*Severe acute asthma*
- Severe asthma would typically present with a **PEF less than 50%** of predicted, or the inability to **speak more than single words** or sentences in one breath.
- Although the heart rate (125 bpm) and respiratory rate (35 bpm) are elevated, they do not meet the more stringent criteria for severe asthma in a 5-year-old (e.g., HR >140 bpm or RR >40 bpm).
*Life-threatening asthma*
- This classification is reserved for patients exhibiting signs of impending respiratory failure, such as a **silent chest**, **cyanosis**, **exhaustion**, **altered consciousness**, or **SpO2 less than 92%**.
- The patient's oxygen saturation of 94% and ability to speak in phrases rule out life-threatening asthma.
*Near-fatal asthma*
- **Near-fatal asthma** is characterized by a raised **pCO2** (indicating respiratory muscle fatigue) and/or requiring **mechanical ventilation**.
- The patient is not in acute respiratory failure and does not exhibit these extreme signs, making this diagnosis incorrect.
*Mild acute asthma*
- Mild asthma exacerbations are usually characterized by **minimal symptoms**, the ability to speak in **full sentences**, and a **PEF greater than 75%** of predicted.
- The patient's **moderate chest wall recession** and PEF of 55% indicate a more significant exacerbation than mild.
Question 60: A 4-year-old girl is brought to the GP surgery with a 2-day history of fever up to 39.4°C and coryza. Her mother is concerned as she has been more lethargic than usual. On examination, she is alert and interactive with a temperature of 38.7°C. She has rhinorrhoea, mildly injected pharynx, and mild cervical lymphadenopathy. Heart rate is 115 beats per minute, respiratory rate is 28 breaths per minute, and capillary refill time is less than 2 seconds. There is no rash or photophobia. Which traffic light system category does this child fall into according to NICE guidelines?
A. Green (low risk)
B. Amber (intermediate risk) (Correct Answer)
C. Red (high risk)
D. Green but requires safety-netting advice only
E. Amber requiring immediate blood tests
Explanation: ***Amber (intermediate risk)***
- According to **NICE guidelines**, a child reported by a parent/carer as being **"more lethargic than usual"** or having **decreased activity** falls into the amber risk category.
- Despite being alert on examination, the significant **parental concern regarding lethargy** is a crucial intermediate risk indicator that warrants careful assessment.
*Green (low risk)*
- The child's reported **lethargy** by the mother is an **amber feature**, which means the child cannot be classified as low risk according to NICE guidelines.
- Green category children typically exhibit **normal social response** and activity, with no concerning parental reports or clinical signs.
*Red (high risk)*
- There are no **red flag signs** such as a non-blanching rash, signs of shock (e.g., prolonged capillary refill time, very severe tachypnoea, or significant mottling), or markedly altered consciousness.
- The child is **alert and interactive** with a normal capillary refill time, indicating an absence of high-risk features.
*Green but requires safety-netting advice only*
- While **safety-netting advice** is essential for all children, the presence of the amber feature (lethargy) means this child requires more than just standard safety-netting alone and needs a higher level of assessment.
- A child in the green category would have no amber or red features, making home management with only safety-netting appropriate.
*Amber requiring immediate blood tests*
- Although the child is in the **Amber category**, NICE guidelines do not mandate **immediate blood tests** for every child in this group, especially if a likely viral source (like coryza) is present.
- Management in the amber category involves individualized clinical judgment, which may include observation, further assessment, or targeted investigations, not necessarily immediate invasive tests.
