Sample Fetal Circulation MCQs with answers
Sample MCQ #1
A 15-year-old adolescent collapses while playing in a high school basketball game without any preceding trauma. He is unconscious and not breathing. Of the following, the BEST sequence of actions is to?
AAdminister a precordial thump and perform a jaw-thrust manoeuvre
BAsk someone to retrieve an automatic external defibrillator and start chest compressions
CImmobilize the cervical spine and attempt to palpate the carotid pulse
DPerform rapid assessment of circulation/airway/breathing and call 108
Show Answer & Explanation ▾
✓ Correct Answer: B. Ask someone to retrieve an automatic external defibrillator and start chest compressions
As per PALS guidelines and OP Ghai 10 th Edition, if the victim/patient is unresponsive and not breathing, begin CPR immediately. Also call for an automatic external defibrillator (AED) to check for rhythm. If there is VF/pVT, give electric shock and continue CPR If there is Asystole or PEA (Pulseless Electrical Activity), give injection epinephrine and continue with CPR. Effective cardiopulmonary resuscitation includes pushing hard (to 1/3 of the anterior-posterior diameter of the chest), pushing fast (100 compressions per minute) with minimal interruptions, and rotating personnel performing compressions every 2 minutes. Reference: OP Ghai 10 th Edition, Pages 763, 765; PALS 2020 Guidelines
Sample MCQ #2
During the examination of the child at birth, you observe that the umbilical cord of the baby has single umbilical artery. While counselling the parents of the baby, you explain them the importance of USG abdomen in this child, due to the risk of which of the following defects?
ARisk of polycystic kidney disease
BRisk of renal agenesis
CRisk of duplication of pelvis
DRisk of Caroli disease
Show Answer & Explanation ▾
✓ Correct Answer: B. Risk of renal agenesis
Single umbilical artery has association with renal agenesis. Hence, all babies with single umbilical artery must be scanned with USG abdomen and KUB to diagnose or rule out the same.

Sample MCQ #3
The MOST common cause of syncope in children is
AWolff-Parkinson-White syndrome
BProlonged QT syndrome
CAtrioventricular block
DNeurocardiogenic syncope
Show Answer & Explanation ▾
✓ Correct Answer: D. Neurocardiogenic syncope
Neurocardiogenic syncope, also known as vasovagal syncope, is a common type of fainting or temporary loss of consciousness that occurs due to a sudden drop in heart rate and blood pressure. This decrease in circulation reduces blood flow to the brain, leading to fainting. Neurocardiogenic syncope can be triggered by several factors, such as: Prolonged standing Extreme emotional stress Pain Heat exposure Physical exertion KEY TAKEAWAYS: In otherwise healthy children, neurocardiogenic syncope is most common . This entity goes by a number of terms, including vasovagal syncope, neurally mediated syncope, and autonomic syncope.
