Final answer:
The first phase of the transition period does not include the passage of meconium. It lasts no longer than 30 minutes and is marked by spontaneous tremors, crying, head movements, and the possibility of the infant suddenly sleeping briefly.
Step-by-step explanation:
The first phase of the transition period is not described by option c, which states that it includes the passage of meconium. Meconium is the first stool of a newborn and is typically passed after birth. It consists of ingested amniotic fluid, cellular debris, mucus, and bile. The transition period lasts no longer than 30 minutes and is marked by spontaneous tremors, crying, head movements, and the possibility of the infant suddenly sleeping briefly.
