What should clinicians check regarding a newborn's first meconium stool?

• A. The timing and characteristics of the stool to ensure normal gastrointestinal function.
• B. Stool volume.
• C. Color only.
• D. Smell.

Answer: (A)

Assessing the newborn’s gastrointestinal function relies on when the first meconium is passed and what it looks like. Meconium is typically passed within the first 24 to 48 hours after birth and is thick, black, tar-like, and sticky. This timing and these characteristics indicate that the gut is showing normal motility and patency. If meconium passage is delayed or absent beyond about 48 hours, it raises concern for possible intestinal problems such as Hirschsprung disease, meconium ileus, or other obstructions, prompting further evaluation. Looking at stool color or smell alone doesn’t reliably indicate GI function, and stool volume isn’t the primary measure for this newborn milestone.
