The nurse is educating a class of expectant parents about fetal development. What is considered fetal age of viability?

Answer and Explanation

The Correct Answer is C

A. At 8 weeks, the embryo is transitioning into the fetal stage of development and is not viable outside the womb. Organs are still in the early stages of formation.

B. While some sources may consider 24 weeks the age of "reasonable viability" with intensive medical support, many medical guidelines recognize viability beginning as early as 20 weeks under optimal conditions.

C. The age of 20 weeks is often cited as the lower threshold of fetal viability due to improved neonatal care, although survival rates improve significantly after this point.

D. At 14 weeks, the fetus is in the second trimester, but it is far too underdeveloped for survival outside the womb.

Correct Answer is D

Explanation

A. A ketogenic diet is not recommended during pregnancy, as carbohydrates are essential for fetal growth and energy. Adequate, balanced nutrition is key during pregnancy.

B. While water intake is important, pregnant clients are advised to drink 8–10 glasses of water daily to support increased blood volume and amniotic fluid. Six glasses would be insufficient.

C. An additional 1,000 calories per day is excessive for early pregnancy. During the first trimester, the calorie increase is minimal (approximately 150–200 calories), with more significant increases later in pregnancy.

D. Taking a prenatal vitamin daily ensures adequate intake of essential nutrients like folic acid and iron, which are critical for preventing neural tube defects and supporting maternal health.

A. Craniofacial abnormalities B. Low birth weight C. Hypersensitivity to noise D. Hyperactivity

Correct Answer is B

Explanation

A. Craniofacial abnormalities is incorrect. While smoking during pregnancy can lead to a variety of issues, craniofacial abnormalities are not a common direct result.

B. Low birth weight is correct. Smoking during pregnancy significantly increases the risk for low birth weight, as it can restrict fetal growth by affecting placental function and blood flow to the fetus.

C. Hypersensitivity to noise is not a typical outcome associated with smoking during pregnancy. This is more related to neurological or sensory processing issues, which may have other causes.

D. Hyperactivity is incorrect. While smoking during pregnancy is associated with long-term developmental issues such as learning difficulties and behavioral problems, hyperactivity is not the immediate concern. It is more likely to be a long-term effect on cognitive and behavioral development.
