Which symptom in a 34-week pregnant woman may indicate preeclampsia?

Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, often the liver and kidneys. One common symptom of preeclampsia is swelling or edema, particularly in the face and hands, which can lead to a noticeable increase in weight and changes in body dimensions. When a woman reports that she no longer wears her wedding ring because it does not fit, this can be indicative of significant swelling in the fingers, a symptom associated with fluid retention often seen in preeclampsia.

The other options reflect various conditions that could affect a pregnant woman, such as unusual cravings (pica), general weight gain impacting clothing fit or feelings of lightheadedness; however, these symptoms are not as directly connected to the specific signs of preeclampsia. Lightheadedness can occur for various reasons in pregnancy, but on its own, it does not signal the potential severity of preeclampsia as clearly as the issue with the ring fitting. Therefore, the statement about no longer wearing a wedding ring due to fit issues stands out as a potentially serious sign that warrants further assessment for preeclampsia.
