DETAILED RATIONALES
Rhythmic jerks of 1–3 seconds that slow during the event indicate which seizure type?
A. Myoclonic
B. Clonic ✅
C. Tonic
D. Subtle
Rationale: Clonic seizures are repetitive rhythmic jerks that can slow as the seizure progresses.
Which seizure type is more common in premature infants and often involves ocular/facial
movements or autonomic changes?
A. Myoclonic
B. Tonic
C. Subtle ✅
D. Absence
Rationale: Subtle seizures are characteristic in preterm infants with less obvious motor signs.
Seizures with posturing and lower-limb extension (may include upper limb extension/flexion) are
called:
A. Myoclonic
B. Clonic
C. Tonic ✅
D. Atonic
Rationale: Tonic seizures feature sustained muscle contraction and posturing.
Seizures with very fast jerking involving flexor muscles are:
A. Clonic
B. Myoclonic ✅
C. Absence
D. Tonic
Rationale: Myoclonic events are brief, rapid jerks, often involving flexor muscle groups.
A delay in resuscitation of an asphyxiated infant may cause persistently high pulmonary vascular
resistance leading to:
A. PDA
B. Failure of neonatal circulation transition / PPHN ✅
C. NEC
D. Hypoglycemia
Rationale: Asphyxia impairs the normal drop in PVR → persistent pulmonary hypertension (PPHN).

Which maternal factor increases risk for tracheoesophageal fistula (TEF) in newborn?
A. Oligohydramnios
B. Maternal diabetes
C. Polyhydramnios ✅
D. Preeclampsia
Rationale: TEF prevents fetal swallowing → excess amniotic fluid (polyhydramnios).
Oligohydramnios means:
A. Excess amniotic fluid
B. Too little amniotic fluid ✅
C. Normal fluid
D. Infected fluid
Rationale: “Oligo-” = decreased.
Polyhydramnios means:
A. Too little amniotic fluid
B. Excess amniotic fluid ✅
C. Normal fluid
D. Bloody fluid
Rationale: “Poly-” = increased.
Neonate with poor feeding, irritability, HR >200 — initial treatment if stable BP?
A. Amiodarone
B. Vagal maneuvers (if stable) then adenosine ✅
C. Immediate cardioversion only
D. Propranolol
Rationale: SVT often treated with vagal maneuvers; if ineffective/unstable → adenosine.
First clinical indicator of heart failure in neonate is:
A. Bradycardia
B. Hepatomegaly
C. Tachypnea ✅
D. Edema
Rationale: Tachypnea reflects pulmonary congestion/edema in neonates.
Respiratory Distress Syndrome (RDS) is characterized by:
A. Normal surfactant
B. Alveolar overdistention
C. Surfactant deficiency, alveolar collapse, ↑airway resistance ✅
D. Upper airway obstruction
Rationale: Lack of surfactant → atelectasis, grunting, retractions.
5-day old with PDA would most likely show:
A. Narrow pulse pressure
