Final answer:
Swelling of the face and fingers in a pregnant woman generally indicates preeclampsia, a risk condition during pregnancy requiring medical attention.
Step-by-step explanation:
Swelling of the face and fingers in a pregnant woman can be a symptom of preeclampsia, which is a condition characterized by high blood pressure and often proteinuria (presence of protein in the urine). Among the options provided, the most accurate answer would indeed be (a) Preeclampsia. This condition can pose risks to both the mother and the fetus and demands medical attention. Some normal symptoms of pregnancy include nausea, heartburn, and frequent urination, with an expected increase in blood volume and respiratory minute volume. However, swelling paired with high blood pressure and proteinuria are indicative of potential preeclampsia, not a normal pregnancy symptom, gestational diabetes, or iron deficiency anaemia.
