Febrile Seizures Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Febrile Seizures. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Febrile Seizures Indian Medical PG Question 1: Which of the following is not typical of Simple Febrile Seizures?
- A. The seizures are followed by Todd's paralysis (Correct Answer)
- B. The age of onset is usually between 6 months and 6 years
- C. The seizures are more likely to occur if the body temperature rises rapidly
- D. The seizures last for less than 15 minutes
Febrile Seizures Explanation: ***The seizures are followed by Todd's paralysis***
- **Todd's paralysis** (postictal hemiparesis) is a focal neurological deficit typically seen after a **focal seizure**, rather than a generalized simple febrile seizure.
- Simple febrile seizures are **generalized tonic-clonic events** and do not typically involve focal neurological deficits such as Todd's paralysis.
*The age of onset is usually between 6 months and 6 years*
- This statement accurately describes the characteristic **age range** for simple febrile seizures, which primarily affect young children.
- The developing brain's susceptibility to fever-induced seizures is highest during this period.
*The seizures are more likely to occur if the body temperature rises rapidly*
- A **rapid rise in body temperature** is a recognized trigger for simple febrile seizures, often more so than the absolute temperature itself.
- This sudden change is thought to overwhelm the immature thermoregulatory system and neuronal excitability in young children.
*The seizures last for less than 15 minutes*
- One of the defining characteristics of a **simple febrile seizure** is its short duration, typically lasting **less than 15 minutes**.
- Seizures lasting longer or occurring in multiple episodes are classified as **complex febrile seizures**.
Febrile Seizures Indian Medical PG Question 2: Simple febrile seizure is defined as
- A. All of the options
- B. Seizure lasts < 15 min
- C. Focal seizure
- D. Generalized seizure <15 min, within 24 hours of fever onset, in a child 6mo-5yr (Correct Answer)
Febrile Seizures Explanation: ***Generalized seizure <15 min, within 24 hours of fever onset, in a child 6mo-5yr***
- A **simple febrile seizure** is characterized by a **generalized tonic-clonic appearance**, lasting less than 15 minutes, and occurring within 24 hours of the onset of fever.
- It typically affects children between the ages of **6 months and 5 years** who do not have a history of afebrile seizures or other neurological conditions.
*All of the options*
- This option is incorrect because simple febrile seizures must meet **specific criteria** regarding duration, number of episodes, and seizure type to be classified as simple.
- While some individual components might be correct, the definition requires a **combination of specific features**, not a general 'all of the options' approach.
*Seizure lasts < 15 min*
- While a duration of less than 15 minutes is a **necessary criterion** for a simple febrile seizure, it is not sufficient on its own.
- Other factors such as the type of seizure (generalized), the number of seizures (single in 24 hours), and the child's age are also crucial for the definition.
*Focal seizure*
- A **focal seizure**, characterized by originating in a specific area of the brain and often manifesting with localized symptoms, is a hallmark of a **complex febrile seizure**, not a simple one.
- Simple febrile seizures are by definition **generalized**, meaning they affect both sides of the brain from the outset.
Febrile Seizures Indian Medical PG Question 3: What is the drug of choice for acute treatment of febrile seizures?
- A. Phenobarbitone
- B. Diazepam (Correct Answer)
- C. Valproate
- D. Carbamazepine
Febrile Seizures Explanation: ***Diazepam***
- **Diazepam** is the drug of choice for the acute treatment of febrile seizures because of its **rapid onset of action** and effectiveness in stopping ongoing seizures [1].
- It is often administered **rectally** or intramuscularly in an emergency setting by parents or caregivers, which is crucial given the urgency of treating a seizure [1].
*Phenobarbitone*
- While **phenobarbitone** has anticonvulsant properties, it is typically used for **long-term prophylaxis** in children with recurrent or high-risk febrile seizures, not for acute treatment.
- It has a **slower onset of action** and can cause **sedation**, making it less suitable for immediate seizure termination [3].
*Valproate*
- **Valproate** is an antiepileptic drug used for various seizure types but is generally **not recommended for acute treatment of febrile seizures** due to its slower onset and potential side effects in young children [2].
- Its use is more relevant in epilepsy management and **long-term seizure prevention**, not as a first-line agent for acute febrile seizure termination [2].
*Carbamazepine*
- **Carbamazepine** is primarily used for **focal seizures** and **trigeminal neuralgia** and is not indicated for the acute management of febrile seizures [2].
- It has a **slower onset** and a different mechanism of action that is not optimal for rapidly stopping a febrile seizure.
Febrile Seizures Indian Medical PG Question 4: Which of the following is true about febrile convulsions?
- A. Recurrent in nature
- B. Occurs at 6 years onwards
- C. No spontaneous remission
- D. Follows high temperature (Correct Answer)
Febrile Seizures Explanation: ***Follows high temperature***
- Febrile convulsions are **directly associated with fever** and occur during febrile illness, typically when body temperature rises above **38°C (100.4°F)**.
- By definition, a febrile seizure occurs in children aged **6 months to 5 years** during a **febrile illness** in the absence of CNS infection or other defined cause.
- The seizure may occur during the **rising phase of fever** or when the temperature is already elevated, making this statement the most accurate characterization.
*Recurrent in nature*
- While febrile convulsions CAN recur, only approximately **30-40% of children** experience recurrent episodes.
- The **majority (60-70%)** of children have only a **single episode**, so stating they are "recurrent in nature" is inaccurate.
- Risk factors for recurrence include: young age at first episode, family history, and brief duration between fever onset and seizure.
*No spontaneous remission*
- This is incorrect; febrile convulsions have **excellent prognosis** with spontaneous resolution.
- Individual episodes typically last only **a few minutes** and resolve spontaneously without intervention.
- The condition itself remits as children grow older, with febrile seizures becoming **rare after age 5-6 years**.
*Occurs at 6 years onwards*
- This is incorrect; febrile convulsions occur in children between **6 months and 5 years of age**, with peak incidence around **18 months**.
- Febrile seizures are **rare after age 6 years**, and a new-onset seizure with fever in an older child warrants investigation for other causes such as CNS infection or epilepsy.
Febrile Seizures Indian Medical PG Question 5: Management of typical febrile seizures includes all except:
- A. Intermittent diazepam
- B. Sponging
- C. Paracetamol or ibuprofen
- D. Prophylactic phenobarbitone (Correct Answer)
Febrile Seizures Explanation: ***Prophylactic phenobarbitone***
- **Continuous prophylactic anticonvulsant therapy** with phenobarbitone is **definitively NOT recommended** for typical (simple) febrile seizures
- The risks of chronic anticonvulsant use—including **sedation, cognitive impairment, and behavioral problems**—significantly outweigh any potential benefits
- Evidence shows prophylactic phenobarbital does **not prevent future epilepsy** and has insufficient benefit in preventing recurrent febrile seizures
- This is the **correct answer** as it is explicitly excluded from management guidelines
*Intermittent diazepam*
- While **not routinely recommended** for typical febrile seizures, intermittent rectal or buccal diazepam may be discussed as a *potential option* for specific situations (frequent recurrences, parental anxiety, prolonged seizures)
- It serves as **rescue medication** to abort an ongoing seizure rather than daily prophylaxis
- Its role in typical febrile seizure management is controversial and limited, but it may be mentioned in comprehensive management discussions
*Sponging*
- **Tepid sponging** is a supportive physical cooling measure used in fever management
- While it does not prevent febrile seizures, it is part of general **symptomatic care** for fever reduction
- Typically used alongside antipyretics to help lower body temperature and improve comfort
*Paracetamol or ibuprofen*
- **Antipyretics** are standard management for fever control and improving the child's comfort
- While they do **not reliably prevent** febrile seizures from occurring, they are essential for **symptomatic fever management**
- Recommended as first-line treatment for fever in children with febrile seizures
Febrile Seizures Indian Medical PG Question 6: All of the following factors are associated with a substantially greater risk of developing epilepsy after febrile seizures, except:
- A. Complex Febrile seizures
- B. Developmental abnormalities
- C. Positive family History of Epilepsy
- D. Early age of onset (Correct Answer)
Febrile Seizures Explanation: ***Early age of onset***
- While earlier onset of febrile seizures (e.g., before 12 months) is associated with an increased risk of *recurrence* of febrile seizures, it is **not independently a strong predictor** of developing epilepsy after febrile seizures compared to the other factors listed.
- The age range for febrile seizures is typically 6 months to 5 years, and seizures within this range, regardless of earlier or later, carry similar baseline risks for subsequent epilepsy.
*Complex Febrile seizures*
- **Complex febrile seizures** (defined by duration >15 minutes, focal features, or multiple seizures within 24 hours) are a significant risk factor for developing later **epilepsy**, particularly temporal lobe epilepsy.
- These features suggest a more significant underlying neurological predisposition or injury.
*Developmental abnormalities*
- Pre-existing **developmental abnormalities** or neurological deficits (e.g., cerebral palsy, developmental delay) are strong predictors of developing **epilepsy** after febrile seizures.
- This indicates a vulnerable brain that is more susceptible to abnormal electrical activity.
*Positive family History of Epilepsy*
- A **positive family history of epilepsy** in a first-degree relative substantially increases the risk of an individual with febrile seizures developing later **epilepsy**.
- This suggests a genetic predisposition to seizure disorders.
Febrile Seizures Indian Medical PG Question 7: What is the recurrence rate of febrile seizures in children?
- A. 25-50% (Correct Answer)
- B. 10-20%
- C. 20-25%
- D. 5-10%
Febrile Seizures Explanation: ***25-50%***
- The recurrence rate for **febrile seizures** is generally cited to be between **25% and 50%**.
- Risk factors for recurrence include a **younger age at presentation** (<18 months), **brief fever duration** before the seizure, a history of febrile seizures in a **first-degree relative**, and a **lower fever temperature** when the seizure occurred.
*10-20%*
- This range is too low for the typical recurrence rate of **febrile seizures**.
- While some specific sub-groups might have lower recurrence, the overall population average is higher.
*20-25%*
- This range is at the lower end of the commonly accepted recurrence rates for **febrile seizures**.
- It might represent a more optimistic estimate or apply to a very specific, low-risk group.
*5-10%*
- This range is significantly lower than the established recurrence rates for **febrile seizures**.
- This percentage might be associated with seizure recurrence in conditions other than febrile seizures, or children with very few risk factors.
Febrile Seizures Indian Medical PG Question 8: Febrile seizure persisting continuously beyond ____ should be treated with midazolam nasal spray:
- A. 3 minutes
- B. 10 minutes
- C. 5 minutes (Correct Answer)
- D. 8 minutes
Febrile Seizures Explanation: ***5 minutes***
- Febrile seizures lasting longer than **5 minutes** are considered **prolonged** and require immediate intervention to prevent progression to status epilepticus.
- **Midazolam nasal spray** is a convenient and effective first-line treatment for prolonged or status epilepticus due to its rapid absorption and anticonvulsant properties.
*3 minutes*
- While it's important to monitor febrile seizures, 3 minutes is generally too short a duration to initiate emergency medication for treatment.
- Many febrile seizures self-terminate within this timeframe, and medical intervention is typically reserved for longer-lasting events.
*10 minutes*
- Waiting until 10 minutes to administer medication for a prolonged febrile seizure is generally too long and increases the risk of complications such as **status epilepticus** and potential neuronal damage.
- Prompt intervention between 5-10 minutes is recommended to prevent these adverse outcomes.
*8 minutes*
- Similar to waiting 10 minutes, waiting 8 minutes to administer medication for a prolonged febrile seizure is generally too long.
- Early intervention after the **5-minute mark** is crucial to improve outcomes and prevent further seizure activity.
Febrile Seizures Indian Medical PG Question 9: The percentage of children with simple febrile seizures who develop epilepsy is:
- A. 1-2% (Correct Answer)
- B. 5-10%
- C. 2-5%
- D. 10-20%
Febrile Seizures Explanation: ***1-2%***
- The risk of developing **epilepsy** after a simple febrile seizure is generally low, estimated to be around **1-2%**.
- This low percentage highlights that simple febrile seizures are typically benign and do not commonly lead to chronic seizure disorders.
*5-10%*
- This percentage is too high for the risk of epilepsy after a **simple febrile seizure**.
- A higher risk might be associated with complex febrile seizures or other neurological predisposition.
*2-5%*
- While closer, this range is still slightly higher than the generally accepted risk for uncomplicated **simple febrile seizures** leading to epilepsy.
- This range might be considered for cases with some atypical features, but not for typical simple febrile seizures.
*10-20%*
- This percentage represents a significantly **elevated risk** that is far beyond what is observed for typical simple febrile seizures.
- Such a high risk would indicate a much more serious underlying neurological disorder or complex seizure presentation.
Febrile Seizures Indian Medical PG Question 10: A 6-year-old with recurrent febrile seizures presents lethargic with a high fever. What is the most appropriate next step in management?
- A. Perform lumbar puncture (Correct Answer)
- B. Consider using antipyretics for comfort
- C. Start anticonvulsants
- D. Order urgent EEG
Febrile Seizures Explanation: ***Perform lumbar puncture***
- The combination of **lethargy**, high fever, and a history of recurrent febrile seizures in a 6-year-old child raises suspicion for **meningitis or encephalitis**, necessitating a prompt **lumbar puncture** to analyze **cerebrospinal fluid (CSF)**.
- While febrile seizures alone are benign, **altered mental status (lethargy)** in conjunction with fever is a red flag for **central nervous system infection**.
*Consider using antipyretics for comfort*
- **Antipyretics** can help reduce fever and improve comfort but do not address the underlying cause of lethargy and potential CNS infection.
- Delaying definitive diagnostic steps like a **lumbar puncture** while waiting for antipyretics to work could worsen the patient's prognosis if a serious infection is present.
*Start anticonvulsants*
- **Anticonvulsants** are primarily used for managing ongoing seizures or preventing recurrent non-febrile seizures but are **not indicated as a first-line diagnostic or emergency treatment** for a child presenting with **fever and lethargy without active seizures**.
- There is no clinical indication of current seizure activity, and the immediate concern is detecting a potential **CNS infection**.
*Order urgent EEG*
- An **EEG (electroencephalogram)** is useful for evaluating seizure disorders or encephalopathy but is **not the most appropriate initial diagnostic step** when a **serious CNS infection like meningitis** is suspected.
- A **lumbar puncture** is crucial for diagnosing or ruling out meningitis, which requires immediate treatment.
