Which of the following is a warning sign that pregnancy may be in danger?

Swelling of the face and fingers can signify a serious condition potentially affecting both the mother and the fetus. It is often associated with complications such as preeclampsia, which is characterized by high blood pressure and damage to other organ systems, commonly the kidneys. When swelling occurs in these areas, it can indicate fluid retention due to increased blood pressure, which can be a warning sign of this life-threatening condition. Preventative monitoring and treatment are crucial in managing potential risks to both the pregnant individual and the developing fetus.

In contrast, regular exercise is generally encouraged during pregnancy to promote overall health, provided there are no contraindications. Increased appetite can be a normal part of pregnancy as the body requires more energy to support fetal development. Frequent urination is also common during pregnancy, primarily due to hormonal changes and pressure from the growing uterus on the bladder. These factors do not typically indicate danger, but rather reflect normal physiological changes associated with pregnancy.
