**Question:** Stillborn child is defined by

A. Birth weight less than 10th percentile for gestational age
B. Birth weight less than 2,500 grams
C. Birth weight less than 1,000 grams
D. Birth weight less than 1,500 grams

**Core Concept:** Stillbirth is defined as the birth of a fetus that has died before or during labor. It is categorized based on birth weight, gestational age, or both.

**Why the Correct Answer is Right:** Option B is correct because the term "stillborn" is often associated with a minimum birth weight of 2,500 grams. This threshold helps distinguish stillbirth from neonatal mortality, which typically occurs within the first 28 days of life.

**Why Each Wrong Option is Incorrect:**

A. Birth weight less than 10th percentile for gestational age (Option A) is not directly mentioned in the definition of stillbirth. While it represents a possible classification criterion, the minimum birth weight is more commonly used.

C. Birth weight less than 1,000 grams (Option C) is too low and commonly associated with neonatal mortality rather than stillbirth. Stillbirth typically occurs at a higher birth weight.

D. Birth weight less than 1,500 grams (Option D) is also too low, similar to Option C, and does not accurately represent the commonly accepted definition of stillbirth.

**Clinical Pearl / High-Yield Fact:** Understanding the definition of stillbirth is essential for accurate documentation, clinical management, and grief counseling of families experiencing this tragic event. Stillbirth is often associated with maternal, fetal, or placental factors that contribute to fetal growth restriction, intrauterine demise, or prolonged rupture of membranes.

**Correct Answer:** B. Birth weight less than 2,500 grams
