Neonatal Seizures Indian Medical PG Practice Questions and MCQs
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.
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.
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
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.
Question 3: All are primary generalised seizures except
- A. Grand mal epilepsy
- B. Petitmal epilepsy
- C. Myoclonic epilepsy
- D. Infantile spasm (Correct Answer)
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].
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)
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.
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
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.
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
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.
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
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.
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
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.
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)
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.
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)
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)
