The term "meconium" specifically refers to the first stool passed by a newborn. This substance is typically thick, sticky, and dark green in color and is composed of materials ingested during the time the fetus was in the womb, including amniotic fluid, mucus, and skin cells. Meconium is typically passed by the newborn within the first 24 to 48 hours of life and is an important indicator of the infant's gastrointestinal tract functioning properly after birth.

The other options do not accurately define meconium. The first cry of a newborn marks the initiation of breathing outside the womb and does not connect to the concept of meconium. A newborn rash refers to skin conditions that can arise shortly after birth, but these are not related to the gastrointestinal processes that meconium indicates. Finally, the initial feeding of a newborn is an important milestone, but it involves the intake of nutrition rather than the passage of stool. Therefore, recognizing meconium as the first stool helps establish key aspects of newborn care and monitoring.
