A nurse is caring for a client who has a positive pregnancy test. The nurse is teaching the client about common discomforts in the first trimester of pregnancy as well as warning signs of potential danger. The nurse should instruct the client to call the clinic if she experiences which of the following manifestations?

A. Facial edema: While mild swelling of the ankles is common in pregnancy, swelling of the face and hands (facial edema) can be a sign of gestational hypertension or preeclampsia. Although preeclampsia typically occurs after 20 weeks, facial edema is a deviation from normal "discomforts" and warrants immediate provider assessment to rule out cardiac or renal complications. B. Nausea and vomiting: "Morning sickness" is a very common expected discomfort in the first trimester due to rising HCG levels. It is only a danger sign if it becomes Hyperemesis Gravidarum (severe dehydration/weight loss). C. Urinary frequency: The growing uterus presses on the bladder during the first trimester, causing frequency. This is an expected finding. D. Leukorrhea: High levels of estrogen stimulate the cervix to produce increased white vaginal discharge (leukorrhea). This is normal unless it is foul-smelling or accompanied by itching (infection).
