Neonatal Seizures Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Neonatal Seizures. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Neonatal Seizures Indian Medical PG Question 1: Which of the following statements is MOST accurate regarding neonatal sepsis?
- A. Meningitis is a late complication of sepsis.
- B. Fever can occur in neonatal sepsis but is not always present. (Correct Answer)
- C. Jaundice is a possible symptom of neonatal sepsis but not definitive.
- D. None of the options.
Neonatal Seizures Explanation: ***Fever can occur in neonatal sepsis but is not always present.***
- This is the **MOST accurate and clinically critical** statement about neonatal sepsis.
- Neonates with sepsis often present with **non-specific symptoms** due to their immature immune system, and **hypothermia or temperature instability** is MORE common than fever.
- The **absence of fever does NOT rule out sepsis** in neonates—this is a fundamental principle in neonatal medicine.
- Temperature instability (including hypothermia) is one of the **primary presenting signs** of neonatal sepsis and represents a critical diagnostic pitfall if not recognized.
*Meningitis is a late complication of sepsis.*
- This statement is **INCORRECT**.
- In neonates, **meningitis** is often an **early or concurrent manifestation** of sepsis, NOT a late complication.
- The immature **blood-brain barrier** in neonates allows rapid CNS seeding, meaning meningitis can occur simultaneously with bacteremia in early-onset sepsis.
- Up to **25-30% of neonatal sepsis cases** have concurrent meningitis, especially with Group B Streptococcus and E. coli.
*Jaundice is a possible symptom of neonatal sepsis but not definitive.*
- This statement is **technically accurate** but NOT the MOST accurate answer.
- While **jaundice** can occur in neonatal sepsis (due to hepatic dysfunction, hemolysis, or cholestasis), it is an extremely **common and often benign finding** in neonates.
- Jaundice is present in **60% of term** and **80% of preterm** neonates, mostly from physiological causes.
- Unlike temperature instability (Option B), jaundice is a **less specific and less critical** diagnostic sign for sepsis.
*None of the options.*
- This option is incorrect because Option B is accurate and represents the most clinically important statement.
Neonatal Seizures Indian Medical PG Question 2: A preterm infant with poor respiration at birth starts throwing seizures at 10 hours after birth. Antiepileptic of choice shall be:
- A. Phenobarbitone (Correct Answer)
- B. Lorazepam
- C. Levetiracetam
- D. Phenytoin
Neonatal Seizures Explanation: ***Phenobarbitone***
- **Phenobarbitone** is the **first-line antiepileptic drug** recommended for neonatal seizures due to its established efficacy and safety profile in this population.
- It acts primarily by **potentiating GABAA receptor-mediated chloride currents**, leading to central nervous system depression and seizure control.
*Lorazepam*
- While **benzodiazepines** like lorazepam can be used for acute seizure cessation, especially status epilepticus, they are generally **not the first-line choice for maintenance therapy** due to potential sedation and respiratory depression in neonates.
- Its short duration of action and risk of rebound seizures make it less suitable as a sole agent for ongoing seizure control.
*Levetiracetam*
- **Levetiracetam** is an increasingly common antiepileptic in neonates, but its long-term efficacy and safety, particularly regarding neurodevelopmental outcomes, are **still under investigation** compared to phenobarbitone.
- While it may be used as a second-line agent or in specific situations, it is **not universally considered the first-line drug of choice** for neonatal seizures.
*Phenytoin*
- **Phenytoin** is typically considered a **second-line or third-line antiepileptic** for neonatal seizures, primarily used if phenobarbitone is ineffective.
- Its use is limited by potential side effects such as **cardiac arrhythmias, hypotension, and infiltration at the injection site**, which can be particularly concerning in premature infants.
Neonatal Seizures Indian Medical PG Question 3: All are primary generalised seizures except
- A. Grand mal epilepsy
- B. Petitmal epilepsy
- C. Myoclonic epilepsy
- D. Infantile spasm (Correct Answer)
Neonatal Seizures Explanation: ***Infantile spasm***
- Infantile spasms are primarily considered a **focal seizure type** that can secondarily generalize, or are sometimes classified as **epileptic encephalopathies** due to their impact on brain development.
- They are characterized by brief, sudden flexion or extension of the body, usually occurring in clusters.
*Grand mal epilepsy*
- This is an older term for **tonic-clonic seizures**, which are a classic example of **generalized seizures** involving both hemispheres of the brain from onset [2].
- They feature a tonic phase (muscle stiffening) followed by a clonic phase (rhythmic jerking) [4].
*Petit mal epilepsy*
- This is an older term for **absence seizures**, which are another well-known type of **generalized seizure** [2].
- They are characterized by brief, sudden lapses of awareness or staring spells, without convulsions [1].
*Myoclonic epilepsy*
- **Myoclonic seizures** involve sudden, brief, shock-like jerks of a muscle or a group of muscles, and are considered a type of **generalized seizure** [1].
- They typically do not involve loss of consciousness and are often seen in syndromes like **juvenile myoclonic epilepsy** [3].
Neonatal Seizures Indian Medical PG Question 4: Which of the following electrolyte abnormalities is a cause of status epilepticus in a child?
- A. Hypokalemia
- B. Hyperkalemia
- C. Hypernatremia
- D. Hyponatremia (Correct Answer)
Neonatal Seizures Explanation: ***Hyponatremia***
- **Hyponatremia** (low sodium levels) can lead to **cerebral edema**, increasing intracranial pressure and predisposing to seizures, including status epilepticus, especially in children.
- Rapid shifts in fluid balance and electrolyte disturbances, such as those seen with severe hyponatremia, can destabilize neuronal membranes and trigger **sustained seizure activity**.
*Hypokalemia*
- While significant **hypokalemia** (low potassium) affects cardiac and muscular function, it is **less commonly a direct cause of seizures** or status epilepticus compared to sodium imbalances.
- Severe hypokalemia can impact neuronal excitability but primarily causes **muscle weakness** and **cardiac arrhythmias**.
*Hyperkalemia*
- **Hyperkalemia** (high potassium) primarily affects **cardiac conduction** and neuromuscular function, leading to **bradycardia** or **cardiac arrest**.
- It is **not typically associated with seizures** or status epilepticus in children.
*Hypernatremia*
- **Hypernatremia** (high sodium) indicates a relative water deficit, leading to cell shrinkage and potentially **intracranial hemorrhage** or **thrombosis**.
- While severe hypernatremia can cause neurological symptoms like **lethargy** or **coma**, it is **less commonly a direct cause of status epilepticus** compared to hyponatremia.
Neonatal Seizures Indian Medical PG Question 5: A sick intubated neonate is having bilateral jerk of both right and left upper limbs with some occasional twitching of neck as well. Likely type of seizures:
- A. Multifocal clonic (Correct Answer)
- B. Multifocal tonic clonic
- C. Focal tonic
- D. Focal clonic
Neonatal Seizures Explanation: ***Multifocal clonic***
- This description fits **multifocal clonic seizures**, characterized by **migratory clonic activity** observed in different body parts at varying times, sometimes simultaneously.
- The **bilateral jerk** of upper limbs and occasional neck twitching point to this pattern, as the involvement is not uniform or generalized, but rather appears in multiple, distinct locations.
*Multifocal tonic clonic*
- This option incorrectly combines multifocal activity with a **tonic component**, which is described as stiffening or sustained contraction, not just jerking.
- While activity may be multifocal, the specific description of "jerk" primarily suggests a **clonic nature**, without a clear tonic phase.
*Focal tonic*
- **Focal tonic seizures** involve sustained **stiffening or contraction** of muscles in a specific, localized area of the body, which is not described.
- The term "jerk" indicates a **clonic movement**, and the involvement of multiple areas (bilateral upper limbs, neck) rules out a single focal onset.
*Focal clonic*
- **Focal clonic seizures** are characterized by rhythmic jerking movements limited to a **single, localized part** of the body without spreading to other areas.
- The presence of jerking in **both upper limbs** and occasional neck twitching indicates activity in multiple sites, not restricted to a single focal area.
Neonatal Seizures Indian Medical PG Question 6: The recommended ambient temperature for NICU is
- A. 20-22° C
- B. 22-26° C (Correct Answer)
- C. 26-30° C
- D. 30-35° C
Neonatal Seizures Explanation: ***22-26° C***
- Maintaining an ambient temperature of **22-26°C** in the NICU is crucial for preventing **cold stress** in neonates.
- This temperature range helps to maintain the baby's **core body temperature**, reducing metabolic demands and ensuring optimal thermal regulation.
*20-22° C*
- While this might be a comfortable room temperature for adults, it is generally **too cold** for newborns in the NICU.
- Temperatures below the recommended range can lead to significant **cold stress**, increasing oxygen consumption and metabolic rate in vulnerable infants.
*26-30° C*
- This temperature range is generally **too warm** for a NICU environment.
- Excessive warmth can lead to **hyperthermia** and sweating, which increases fluid loss and can be detrimental to a neonate's health.
*30-35°C*
- This temperature is **dangerously high** for neonates in the NICU.
- Such high temperatures would significantly increase the risk of **hyperthermia, dehydration**, and other severe complications, compromising the infant's well-being.
Neonatal Seizures Indian Medical PG Question 7: A term neonate, with a birth weight of 2700 g, who is otherwise well, and is exclusively breastfed, presents for routine evaluation. His total serum bilirubin is found to be 14mg/dl on day 5. What is the management?
- A. No active treatment required (Correct Answer)
- B. Stop breastfeeding for 2 days
- C. Phototherapy
- D. Exchange transfusion
Neonatal Seizures Explanation: ***No active treatment required***
- A total serum bilirubin of **14 mg/dL** on day 5 in an otherwise well, exclusively breastfed term neonate (birth weight 2700g, which is >2500g) falls within the **physiologic jaundice range** and below thresholds for intervention.
- This level is considered **normal for breastfed infants** at this age and does not warrant medical intervention as per current guidelines.
*Stop breastfeeding for 2 days*
- This intervention, known as **breast milk jaundice interruption**, is usually reserved for higher bilirubin levels or if there is concern for significant breast milk jaundice, which is not indicated here.
- Temporarily stopping breastfeeding can disrupt the establishment of breastfeeding and is generally discouraged unless strictly necessary.
*Phototherapy*
- **Phototherapy** is indicated for bilirubin levels typically >15-18 mg/dL in a healthy term neonate on day 5, depending on risk factors, which this infant does not meet.
- It works by converting unconjugated bilirubin into water-soluble isomers that can be excreted more easily.
*Exchange transfusion*
- **Exchange transfusion** is reserved for severe hyperbilirubinemia, usually with bilirubin levels approaching or exceeding 20-25 mg/dL, especially if there are signs of **acute bilirubin encephalopathy**.
- This level is far below the threshold for such an invasive procedure.
Neonatal Seizures Indian Medical PG Question 8: Most common cause of convulsion on the first day of life in a newborn is:
- A. Perinatal asphyxia (Correct Answer)
- B. Hypoglycemia
- C. Hypocalcemia
- D. Head injury
Neonatal Seizures Explanation: ***Perinatal asphyxia***
- **Perinatal asphyxia** (hypoxic-ischemic encephalopathy) is the most common cause of seizures in the first 24 hours of life in neonates.
- The resulting **cerebral injury** from oxygen deprivation and ischemia leads to neuronal excitability and seizure activity.
- Accounts for the majority of seizures presenting on day 1 of life, particularly following difficult deliveries or fetal distress.
*Hypoglycemia*
- While **hypoglycemia** can cause seizures in newborns, it is generally less common than perinatal asphyxia as the primary cause on the very first day.
- Seizures due to hypoglycemia often occur in vulnerable infants like those with **diabetic mothers**, intrauterine growth restriction, or those experiencing a sudden drop in glucose.
- Usually presents within 2-3 hours after birth in at-risk infants.
*Hypocalcemia*
- **Early neonatal hypocalcemia** can cause seizures, but typically presents slightly later, usually after 24-48 hours of life.
- More common in infants with **low birth weight**, prematurity, birth asphyxia, or those born to diabetic mothers.
- Related to immature parathyroid function and increased phosphate load.
*Head injury*
- **Birth trauma** with intracranial hemorrhage can cause seizures through direct neuronal damage, but is less frequent than perinatal asphyxia as a cause of day 1 seizures.
- Risk factors include **difficult instrumental deliveries**, macrosomia, and precipitous labor.
- Incidence has decreased significantly with improved obstetric practices.
Neonatal Seizures Indian Medical PG Question 9: Which of the following is NOT included in the resuscitation of a neonate with HR < 60/min?
- A. Endotracheal tube intubation
- B. Chest compression
- C. Adrenaline
- D. None of the above (Correct Answer)
Neonatal Seizures Explanation: ***None of the above***
- All listed interventions—**endotracheal tube intubation**, **chest compressions**, and **adrenaline administration**—are standard components of neonatal resuscitation when the heart rate remains below 60 beats/min despite initial steps.
- This question asks which is *NOT* included, implying that all options are, in fact, appropriate interventions in this critical scenario.
*Endotracheal tube intubation*
- This is a critical step in **securing the airway** and ensuring effective positive pressure ventilation when other methods fail or prolonged mechanical ventilation is anticipated.
- It's indicated if the heart rate remains below 60 bpm despite adequate bag-mask ventilation and chest compressions.
*Chest compression*
- **Chest compressions** are initiated when the heart rate is less than 60 bpm *after* 30 seconds of effective positive pressure ventilation.
- They are used in conjunction with positive pressure ventilation to improve cardiac output and myocardial perfusion.
*Adrenaline*
- **Adrenaline** is administered if the heart rate remains below 60 bpm *despite* adequate ventilation and chest compressions.
- It acts as a potent **vasopressor** and **cardiac stimulant**, increasing heart rate and contractility.
Neonatal Seizures Indian Medical PG Question 10: Erythematous blotchy rash is seen on the abdomen, trunk, and face of a 3-day-old child along with yellowish papules. The child appears well. What is the appropriate management?
- A. Topical steroid and antibiotic lotion
- B. Topical steroid cream
- C. Intravenous antibiotics
- D. No treatment (Correct Answer)
Neonatal Seizures Explanation: ***No treatment (Correct Answer)***
The described symptoms—erythematous blotchy rash with yellowish papules on the abdomen, trunk, and face in a well-appearing 3-day-old neonate—are **classic for erythema toxicum neonatorum**.
**Key Features:**
- **Benign, self-limiting rash** of unknown etiology
- Affects **50-70% of term newborns**
- Typically appears on **days 2-5** of life
- Characterized by **erythematous macules/patches** with overlying **yellowish-white papules/pustules**
- Infant appears **well and thriving**
- **Resolves spontaneously** within 1-2 weeks without treatment
- Histology shows **eosinophils** in pustules
**Management:** Reassurance to parents; no medical intervention required.
---
*Topical steroid and antibiotic lotion (Incorrect)*
This approach is inappropriate because erythema toxicum neonatorum is:
- **Not an infection** (no bacterial or fungal cause)
- **Not an inflammatory condition** requiring steroids
- Misdiagnosis and overtreatment could lead to unnecessary side effects, antibiotic resistance, and mask other conditions
---
*Topical steroid cream (Incorrect)*
Topical steroids are:
- **Unnecessary** for this benign, self-resolving condition
- **Potentially harmful** in neonates (can cause skin atrophy, increased absorption)
- Provide **no therapeutic benefit** for erythema toxicum neonatorum
---
*Intravenous antibiotics (Incorrect)*
Systemic antibiotics are:
- **Entirely unwarranted** as this is a non-infectious, benign rash
- Would represent **gross overtreatment** with significant risks
- Contribute to **antibiotic resistance**
- Carry risks of adverse reactions, disruption of normal flora, and unnecessary hospitalization
**Differentials to consider (but not present here):**
- Transient neonatal pustular melanosis (present at birth)
- Neonatal acne (appears later, at 2-4 weeks)
- Miliaria (smaller, clear vesicles)
- Infectious causes (infant appears ill, requires septic workup)
