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 crucial because birth weight is the single most important determinant of a newborn's chances of survival and healthy development.
The classification applies to any infant with a birth weight under 2500g, regardless of whether they are born prematurely (preterm) or are small for their gestational age (SGA).
This threshold is used globally as a key public health indicator to monitor maternal and child health.

Option A: While a baby weighing 2250 gm is classified as having low birth weight, this is not the defining threshold. The definition includes all babies weighing up to, but not including, 2500 gm.
Option B: A birth weight of 2750 gm is considered normal. The normal range for birth weight is typically between 2500 gm and 4000 gm.
Option D: A birth weight of 3000 gm is a healthy, normal weight for a newborn and is well above the threshold for low birth weight.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition and classification of Low Birth Weight (LBW) as background academic context rather than a clinical decision trigger.
LBW is a major predictor of neonatal morbidity and mortality. These infants are at a significantly higher risk for hypothermia, hypoglycemia, respiratory distress syndrome, infections, and long-term neurodevelopmental problems.
Nursing care for LBW infants is intensive and focuses on thermoregulation (e.g., Kangaroo Mother Care, incubators), specialized nutritional support (as sucking reflex may be poor), and meticulous infection control measures.
What if? If a baby's birth weight is 1400 gm, they are classified as Very Low Birth Weight (VLBW). This signifies a much higher risk profile than a baby weighing 2400 gm (LBW) and necessitates care in a specialized Neonatal Intensive Care Unit (NICU) with advanced monitoring and interventions.

How to Approach the Question

Identify the core of the question: It asks for the specific weight threshold that defines a 'Low Birth Weight' (LBW) baby.
Recognize this as a factual recall question based on a standard international definition from the World Health Organization (WHO).
Access your knowledge base for the standard definition of LBW in neonatology.
Recall that the standard definition is a birth weight of less than 2500 grams.
Compare this definition to the given options and select the one that matches the threshold.
