A very low birth weight infant has birth weight of less than -

Appeared in: UPPSC 2023

Explanation

A Very Low Birth Weight (VLBW) infant is defined by the World Health Organization (WHO) and other medical bodies as having a birth weight of less than 1500 grams.
This specific weight category is used to stratify risk and guide the level of neonatal care required.
VLBW infants are at a very high risk for mortality and a wide range of morbidities due to the immaturity of their organ systems.
The classification is independent of the infant's gestational age, although most VLBW infants are also preterm.

Why Other Options Were Wrong

Option A: A birth weight of less than 1000 grams defines an Extremely Low Birth Weight (ELBW) infant.
Option B: A weight of 2000 grams falls under the general category of Low Birth Weight (LBW), but it does not meet the specific criteria for VLBW.
Option C: A birth weight of less than 2500 grams is the definition for the broader category of Low Birth Weight (LBW).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Neonatal birth weight classifications as background academic context rather than a clinical decision trigger.
VLBW infants are at a significantly increased risk for complications such as respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, sepsis, and long-term neurodevelopmental problems.
Nursing care for VLBW infants is highly specialized and focuses on meticulous thermoregulation (using incubators), nutritional support (often starting with parenteral nutrition), infection prevention, and respiratory support (like CPAP or mechanical ventilation).
What if? If an infant's birth weight was 950g, they would be classified as Extremely Low Birth Weight (ELBW). This places them in an even higher risk category, requiring the most advanced life support and intensive monitoring available in a Level III or IV NICU.

How to Approach the Question

First, identify the key term in the question stem, which is 'very low birth weight'.
Recognize that this is a factual recall question that requires knowledge of standard neonatal classifications.
Mentally review the established weight categories for newborns: Normal, Low Birth Weight (LBW), Very Low Birth Weight (VLBW), and Extremely Low Birth Weight (ELBW).
Recall the specific weight threshold for VLBW, which is less than 1500 grams.
Compare this recalled fact with the given options and select the one that matches.
