What is the significance of fetal viability?

Fetal viability primarily refers to the ability of the fetus to survive outside the womb, which is determined by several factors including gestational age, weight, and overall health of the fetus. Typically, this term is used to indicate the point in pregnancy, usually around 24 weeks of gestation, where a fetus has a reasonable chance of survival if born prematurely, given appropriate medical care. Understanding fetal viability is crucial for healthcare providers as it influences decisions regarding management of pregnancies, especially those at risk for preterm labor or other complications.

While the other options touch on aspects relevant to pregnancy, they do not accurately define fetal viability. The risk of miscarriage pertains more to the early stages of pregnancy and does not relate to the fetus's capability of independent survival. Maternal nutritional status is important for fetal development and health during pregnancy but does not directly define viability. Fetal growth patterns are indicative of how well the fetus is developing within the womb but do not signify whether the fetus can survive outside it. Hence, the notion of fetal viability is specifically about the potential for independent life beyond the womb.
