Explanation

A high-risk infant is a newborn with a greater chance of morbidity or mortality, with low birth weight being a primary criterion for this classification.
An infant with a birth weight of 2 kg (2000 g) is defined as a Low Birth Weight (LBW) infant, as the threshold for LBW is a weight less than 2.5 kg (2500 g).
LBW is a major risk factor for numerous complications, including hypothermia (low body temperature), hypoglycemia (low blood sugar), respiratory distress, and infection, which require specialized care.

Option A: A birth weight of 2.5 kg (2500 g) is the lower limit of the normal weight range. It is not classified as low birth weight, which is defined as being less than 2500 g.
Option B: While breastfeeding is the recommended method of feeding, using artificial formula does not, by itself, place an infant in the high-risk category at birth compared to major physiological factors like low birth weight.
Option D: The APGAR score assesses a newborn's immediate adaptation to extrauterine life. A score of 8 (out of 10) is considered normal and indicates the infant is in good health.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of a high-risk infant based on birth parameters as background academic context rather than a clinical decision trigger.
Nurses in labor and delivery or neonatal units must be able to rapidly identify high-risk infants based on parameters like birth weight to initiate critical interventions, such as thermal regulation (e.g., placing the infant in an incubator or using skin-to-skin care), blood glucose monitoring, and providing feeding support.
The initial assessment at birth, including weight and APGAR scoring, is fundamental for triaging newborns. It determines whether an infant requires routine postnatal care, admission to a Special Care Baby Unit (SCBU), or intensive care in a Neonatal Intensive Care Unit (NICU).
What if? If the infant's weight was 2.6 kg (normal) but the APGAR score was 4, the APGAR score would become the primary indicator of high risk. The focus would shift from weight-related risks to immediate resuscitation and stabilization due to poor transition to extrauterine life.

How to Approach the Question

First, understand the question's core task: to identify the 'high-risk' infant from the given options.
Next, evaluate each option against standard neonatal definitions and risk factors.
Recall the definition of Low Birth Weight (LBW) as a birth weight of less than 2.5 kg (2500 grams).
Compare the birth weights in the options to this definition. An infant weighing 2 kg is clearly LBW, while an infant weighing 2.5 kg is at the cutoff for normal weight, not below it.
Recall the interpretation of the APGAR score. A score of 7-10 is normal, so a score of 8 indicates a healthy infant.
Consider the relative importance of the risk factors. LBW is a major, universally recognized criterion for a high-risk infant, whereas artificial feeding is a secondary risk factor. The infant with the most definitive and significant risk factor is the correct answer.
