Explanation

The World Health Organization (WHO) and international medical consensus define Low Birth Weight (LBW) as a birth weight of less than 2500 grams (2.5 kg).
This definition is applied irrespective of the infant's gestational age, meaning it includes both preterm babies and full-term babies who are small for their gestational age.
Identifying LBW is a critical first step in recognizing 'at-risk' infants who have a higher chance of mortality and morbidity and require specialized neonatal care.

Option A: This is an incorrect cutoff for the general definition of Low Birth Weight. The standard definition begins at less than 2500g.
Option C: A baby weighing between 2500g and 3000g falls within the normal birth weight range. This option is incorrect as it misclassifies normal-weight infants.
Option D: This value defines a specific, more severe subcategory of low birth weight, not the general category itself.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition of Low Birth Weight (LBW) in neonates as background academic context rather than a clinical decision trigger.
Identifying a Low Birth Weight (LBW) infant is a critical nursing responsibility as it immediately flags the baby as 'at-risk'. These infants are more susceptible to hypothermia, hypoglycemia, infection, and respiratory distress.
Nurses must initiate specific protocols for LBW babies, including thermal regulation (radiant warmer or incubator), frequent blood glucose monitoring, and specialized feeding plans (e.g., gavage feeding if sucking reflex is poor).
What if? If a baby weighs 2490g, they are classified as LBW and receive intensive monitoring and support. If another baby weighs 2510g, they are classified as Normal Birth Weight. This small 20g difference completely changes the initial care pathway, highlighting the importance of precise measurement and classification.

How to Approach the Question

First, identify the core of the question, which is asking for a standard medical definition: 'Low birth weight'.
Recognize that such definitions are often standardized by global health bodies like the WHO. Access your knowledge of these fundamental pediatric classifications.
Evaluate each option against the standard definition. The definition of LBW is a birth weight less than 2500g.
Eliminate options that define sub-categories (like VLBW at <1500g) or fall within the normal range (like <3000g).
Select the option that precisely matches the internationally accepted cutoff for Low Birth Weight.
