Q1 QUESTION 1 OF 62
What triggers the newborn's first breath?
CORRECT ANSWER
Chemical: hypercarbia, acidosis, hypoxia; Mechanical: chest compression/recoil.
RATIONALE
Increased levels of carbon dioxide (hypercarbia) and resulting acidosis, coupled with reduced oxygen levels (hypoxia),
stimulate respiratory centers in the brain, while chest compression during delivery aids lung expansion, initiating the
newborn's first breath. This dual mechanism highlights the interplay between chemical and mechanical factors
essential for effective transition to extrauterine life.
Q2 QUESTION 2 OF 62
What closes the ductus arteriosus?
CORRECT ANSWER
Increased oxygen + decreased prostaglandins.
RATIONALE
Increased oxygen levels at birth stimulate smooth muscle contraction, leading to the closure of the ductus arteriosus,
while decreased prostaglandins diminish the vasodilatory effects that maintain its patency. This physiological
transition is critical for normal postnatal circulation, redirecting blood flow to the lungs for oxygenation.
Q3 QUESTION 3 OF 62

, What is the top priority during newborn transition?
CORRECT ANSWER
Thermoregulation: WARM, DRY, STIMULATE.
RATIONALE
Maintaining normothermia is critical during the newborn transition to prevent hypothermia, which can lead to
increased oxygen demand and impaired thermoregulation. Immediate warming, drying, and gentle stimulation
facilitate the establishment of stable body temperature and support the transition to extrauterine life.
Q4 QUESTION 4 OF 62
How do newborns make heat?
CORRECT ANSWER
Burn brown adipose tissue using O2 + glucose.
RATIONALE
Newborns generate heat through non-shivering thermogenesis, primarily by metabolizing brown adipose tissue,
which is rich in mitochondria and vascularized, using oxygen and glucose to produce heat and maintain body
temperature in the absence of shivering. This process is critical for thermoregulation and energy expenditure in
neonates.
Q5 QUESTION 5 OF 62
What are the signs of cold stress and the first action?
CORRECT ANSWER
Signs: lethargy, bradycardia, respiratory distress, poor feeding, cool/pale skin. First action: obtain temperature
and rewarm.
RATIONALE
Cold stress in neonates manifests through lethargy, bradycardia, respiratory distress, poor feeding, and hypothermia,
indicating inadequate thermoregulation. Immediate assessment of body temperature is critical for implementing
appropriate rewarming strategies to restore normothermia and support physiological stability.
