Section A: Fetal Physiology and Transition
Question 1
Before birth, pulmonary vascular resistance in the fetal lungs is typically:
A) Low
B) Normal
C) High
D) Variable
Answer: C) High
Explanation: During fetal life, the lungs are fluid-filled and non-functional for gas exchange.
Pulmonary vascular resistance is elevated due to hypoxic vasoconstriction, mechanical
compression of pulmonary vessels by fluid-filled alveoli, and the absence of rhythmic lung
inflation. This high resistance diverts blood flow away from the lungs through the ductus
arteriosus to the systemic circulation. Following birth, with the onset of breathing and
increased oxygen tension, pulmonary vascular resistance dramatically decreases, facilitating
the transition to extrauterine life.
Question 2
Which physiological changes occur during the normal transition from fetal to neonatal
circulation?
A) Pulmonary vascular resistance decreases and systemic vascular resistance increases
B) Pulmonary vascular resistance increases and systemic vascular resistance decreases
C) Both pulmonary and systemic vascular resistance decrease
D) Both pulmonary and systemic vascular resistance increase
Answer: A) Pulmonary vascular resistance decreases and systemic vascular resistance
increases
Explanation: At birth, the clamping of the umbilical cord removes the low-resistance
placental circulation, causing systemic vascular resistance to rise. Simultaneously, the
initiation of breathing expands the lungs, increasing oxygen tension and triggering pulmonary
vasodilation, which decreases pulmonary vascular resistance. This reversal of pressure
,gradients facilitates closure of the ductus arteriosus and foramen ovale, establishing the
neonatal circulatory pattern. Understanding this physiological transition is fundamental to
appreciating why some newborns require respiratory support during the first minutes of life.
Section B: Anticipation and Preparation for Resuscitation
Question 3
A qualified resuscitation team with comprehensive skills should be immediately available for
every delivery. Which skills should team members possess?
A) Vacuum extraction and lumbar puncture
B) Positive pressure ventilation, endotracheal intubation, emergency vascular access,
medication administration, and chest compressions
C) Only positive pressure ventilation and chest compressions
D) All advanced neonatal procedures including surgical interventions
Answer: B) Positive pressure ventilation, endotracheal intubation, emergency vascular
access, medication administration, and chest compressions
Explanation: Effective neonatal resuscitation requires a team capable of performing a range
of interventions. The core competencies include positive pressure ventilation (the most
frequently needed intervention), endotracheal intubation for advanced airway management,
emergency vascular access for medication and fluid administration, and chest compressions
for severe bradycardia or cardiac arrest. While vacuum extraction is an obstetric procedure,
lumbar puncture is a diagnostic intervention not required during acute resuscitation. A skilled
team ensures rapid, coordinated response to the newborn's needs.
Question 4
When planning for a delivery where resuscitation is anticipated, what is the recommended
timeframe for applying pulse oximetry?
A) Immediately upon arrival at the radiant warmer
B) After completing the initial steps of resuscitation
C) Within 2 minutes of delivery
D) Only after 30 seconds of positive pressure ventilation
Answer: B) After completing the initial steps of resuscitation
, Explanation: Pulse oximetry should be applied after the initial steps of resuscitation
(warming, drying, positioning, clearing the airway if needed, and stimulating) have been
completed. This approach allows for rapid assessment of whether the newborn is
transitioning appropriately. If the heart rate remains below 100 beats per minute or the baby
has persistent central cyanosis after initial steps, pulse oximetry provides objective data about
oxygen saturation to guide supplemental oxygen therapy. This sequential approach ensures
that pulse oximetry is used when clinically indicated without delaying critical initial
stabilization.
Question 5
To ensure immediate access during an emergency, where should the laryngeal mask be
positioned?
A) In the code cart
B) At the radiant warmer
C) In the supply closet
D) In the emergency supplies box
Answer: B) At the radiant warmer
Explanation: Equipment that may be needed emergently during neonatal resuscitation
should be immediately accessible at the radiant warmer where the resuscitation takes place.
The laryngeal mask airway serves as an alternative airway device when face mask ventilation
is ineffective or endotracheal intubation is unsuccessful or not feasible. Having it at the
radiant warmer eliminates delays associated with retrieving equipment from distant locations
and ensures that the resuscitation team can promptly implement this important airway
strategy when indicated.
Question 6
Which of the following situations warrant consideration of using a cardiac monitor during
neonatal resuscitation?
A) The heart rate is difficult to auscultate
B) Positive pressure ventilation is required
C) The baby is not vigorous at birth
D) Pulse oximetry does not provide a reliable signal
