Question

The gestation time of prenatal development after which if the foetus is born, it can survive is referred to as

• A. Age of viability
• B. Pre-term
• C. Small for date
• D. Full term

Hint:

Age of Viability = Point in gestation ($22-24$ weeks) at which a fetus can survive extrauterine life.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Prenatal human development defines the gestational milestone where fetal organ systems achieve functional maturity for extrauterine life.

Step 2: Detailed Explanation:
1. Age of Viability: The critical point in fetal gestation (typically between 22 to 24 weeks of gestation) at which the fetal lungs have developed sufficient pulmonary surfactant and the brain can regulate breathing, enabling the infant to have a chance of survival outside the womb with medical support.
2. Pre-term: Born before 37 completed weeks.
3. Full Term: Born between 37 and 42 completed weeks.

Step 3: Final Answer:
Therefore, this gestation time is referred to as Age of viability, corresponding to option (A).
