FAU Advanced Health Assessment Practice Test

At 12 weeks of pregnancy, the development of the fetus and the body's physiological changes result in various symptoms. Visible fetal movement generally does not occur until much later in the pregnancy, typically around 18 to 20 weeks. By this point, the fetus is larger and its movements can be felt outside the mother's abdomen.

In contrast, nausea, fatigue, and increased urine output are all symptoms commonly experienced in the first trimester. Nausea is a hallmark of early pregnancy, often referred to as morning sickness. Fatigue is also a frequent complaint, largely due to hormonal changes and the body’s increased effort to support the developing fetus. Increased urine output can result from hormonal changes as well as an increase in blood volume and kidney function early in pregnancy.

Understanding these timelines and typical symptoms helps in assessing the progression and health of the pregnancy during the early stages.
