Explanation

The World Health Organization (WHO) and international medical consensus define a preterm or premature birth as one that occurs before 37 completed weeks of gestation.
This cutoff is critical because babies born before this point have not had enough time to fully develop in the womb, leading to a higher risk of health complications.
Gestational age is calculated from the first day of the mother's last menstrual period.

Option B: A baby born at 42 weeks is considered post-term, not premature. Post-term pregnancies also carry risks, but they are different from those of prematurity.
Option C: A gestational period of 53 weeks is physiologically impossible for a human pregnancy. A typical pregnancy lasts about 40 weeks.
Option D: A gestational period of 56 weeks is physiologically impossible for a human pregnancy. This is far beyond the normal range of gestation.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition of premature birth based on gestational age as background academic context rather than a clinical decision trigger.
Nurses must be able to quickly identify a preterm infant to initiate specialized care protocols immediately. This includes assessing for respiratory distress, maintaining temperature, and monitoring blood glucose.
The distinction between preterm and low birth weight is important. A baby can be preterm but have an appropriate weight for their gestational age, or they can be term but have a low birth weight due to growth restriction. Both require careful monitoring.
What if? If a baby is born at 37 weeks and 2 days, they are considered 'Early Term' (37w0d to 38w6d). While technically 'term', they are still at a slightly higher risk for some complications compared to 'Full Term' (39w0d to 40w6d) babies, and nurses should monitor them closely for issues like feeding difficulties and jaundice.

How to Approach the Question

Identify the key term in the question: 'premature baby'.
Recall the standard medical definition for different gestational age classifications.
The definition of 'preterm' or 'premature' is a foundational concept in obstetrics and pediatrics.
Evaluate the given options against this definition. A premature baby is one born before 37 completed weeks.
Select the option that matches this definition.
Eliminate options that represent term, post-term, or impossible gestational ages.
