Explanation

The World Health Organization (WHO) and international agreements define Low Birth Weight (LBW) as a birth weight of less than 2500 grams (2.5 kg).
This definition applies regardless of the baby's gestational age, meaning it includes both preterm infants and full-term infants who are small for their gestational age (SGA).
The 2500g cutoff is a critical public health indicator used to identify infants at increased risk of mortality, morbidity, and developmental problems.
The measurement should ideally be taken within the first hour of life before significant postnatal weight loss occurs.

Option A: A birth weight of 2000 g is indeed low birth weight, but it is not the defining threshold. This value falls within the LBW category but does not define its upper limit.
Option B: This is an arbitrary value below the standard cutoff. While a baby weighing 2250 g is considered an LBW baby, this value does not represent the official international definition.
Option D: A birth weight of 3000 g (3.0 kg) is considered a normal and healthy weight for a newborn. The average birth weight in India is around 2800-3000 g.

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) as background academic context rather than a clinical decision trigger.
Identifying an infant as LBW is a critical first step for nurses to initiate specialized care protocols aimed at preventing life-threatening complications.
LBW infants require meticulous nursing care focusing on thermoregulation (e.g., Kangaroo Mother Care), nutritional support (e.g., managing feeds to prevent hypoglycemia), and strict infection control.
What if? If a baby weighs 2600g (not LBW) but is born at 34 weeks gestation (preterm), the nurse must recognize that while the baby is not classified as LBW, they are still at high risk for the same complications (hypothermia, respiratory distress, feeding issues) due to prematurity and require similar intensive monitoring and care.

How to Approach the Question

Identify the core question: The question asks for the specific weight threshold that defines 'Low Birth Weight'.
Recognize this as a factual recall question based on a standard international definition.
Recall the definition provided by major health organizations like the WHO.
Evaluate the options against the recalled definition. The standard definition is a weight less than 2500 grams.
Select the option that corresponds to this standard value.
