Which of the following findings indicates a potential complication during a prenatal visit in a client at 32 weeks of gestation?

A positive glucose test result during a prenatal visit at 32 weeks of gestation raises concern for gestational diabetes. This condition can lead to various complications for both the mother and the fetus if not managed appropriately. It can result in excessive fetal growth (macrosomia), which can complicate labor and delivery, as well as increase the risk of cesarean delivery. Additionally, gestational diabetes can lead to maternal health issues such as preeclampsia. Thus, a positive glucose test result is a pertinent finding that requires further evaluation and management to ensure the health of both the mother and the baby.

In contrast, a blood pressure reading of 130/80 mmHg is generally considered normal for a pregnant woman and is not typically indicative of a complication. The fundal height measuring 30 cm is also within a reasonable range, as it typically corresponds to the gestational age, and a weight gain of 1 kg since the last visit may be acceptable, depending on the client's overall weight gain pattern and health status during the pregnancy.
