What could be the result of fetal head compression?
Uteroplacental insufficiency.
Spontaneous rupture of membranes.
Altered fetal cerebral blood flow.
Umbilical cord compression.
The Correct Answer is A
Choice A rationale: Uteroplacental insufficiency causes late decelerations due to reduced oxygenation, not mechanical pressure. It reflects placental dysfunction, not direct cranial compression effects.
Choice B rationale: Spontaneous rupture of membranes increases infection and labor risk but does not directly alter cerebral perfusion or trigger vagal responses linked to head compression.
Choice C rationale: Altered fetal cerebral blood flow results from cranial pressure during contractions, triggering vagal stimulation and early decelerations. This is the physiological response to head compression.
Choice D rationale: Umbilical cord compression causes variable decelerations due to transient blood flow obstruction, unrelated to cranial pressure or cerebral perfusion changes.

Correct Answer is C
Explanation
Choice A rationale
Placing a newborn under a radiant heat warmer after birth does not directly prevent basal metabolic rate reduction. The primary function of a radiant heat warmer is to maintain the newborn’s body temperature and prevent hypothermia.
Choice B rationale
While brown fat production is a mechanism used by newborns to generate heat, placing a newborn under a radiant heat warmer does not stimulate brown fat production.
Choice C rationale
The primary purpose of placing a newborn under a radiant heat warmer after birth is to maintain the newborn’s body temperature. Newborns can lose heat rapidly, as they have a
large surface area compared to their body weight. The radiant heat warmer provides a controlled environment that helps maintain the newborn’s body temperature.
Choice D rationale
Preventing hypothermia is a key reason for placing a newborn under a radiant heat warmer. However, the direct purpose of the warmer is to maintain the newborn’s body temperature.
