Problem: Kendra returns to the clinic at 28 weeks' gestation. Her husband Louis comes with her this time. Louis tells you that he is worried about Kendra's blood pressure and thinks it may be time for her to stop her part-time job, as she is on her feet all day when she works. You review Kendra's lab results and vital signs, as well as her records of blood pressures and fetal movements. Because you are concerned that Kendra may be developing preeclampsia, you next ask her about the presence of which symptoms?
