Assessment of a pregnant woman and her fetus reveals tachycardia and hypertension. There is also evidence suggesting vasoconstriction. The nurse would question the woman about use of which substance?

Choice A Reason: This is correct because this response provides realistic and supportive advice for a woman who wants to have a baby with lupus. Lupus is an autoimmune disease that causes inflammation and damage to various organs and tissues. Lupus can affect fertility and pregnancy outcomes, such as increasing the risk of miscarriage, preterm delivery, preeclampsia, or neonatal lupus. Therefore, it is important for the woman to have her lupus under control before conceiving and to consult with her doctor about her treatment plan and prenatal care.

Choice B Reason: This is incorrect because this response is discouraging and insensitive for the woman who wants to have a baby with lupus. Lupus does not necessarily prevent a woman from having a healthy pregnancy and a healthy baby, as long as she follows her doctor's recommendations and monitors her condition closely. The nurse should respect the woman's reproductive choices and provide information and support.

Choice C Reason: This is incorrect because this response is inaccurate and misleading for the woman who wants to have a baby with lupus. Lupus can have various effects on pregnancy, such as causing flares or complications that can affect both the mother and the baby. The nurse should educate the woman about the possible risks and benefits of pregnancy with lupus and help her prepare for any challenges.

Choice D Reason: This is incorrect because this response is vague and alarming for the woman who wants to have a baby with lupus. Lupus treatment may or may not change during pregnancy, depending on the type and severity of lupus, the medications used, and the stage of pregnancy. The nurse should explain the rationale and safety of any medication changes and address any concerns or questions that the woman may have.

Choice A Reason: This is correct because Chadwick's sign is a bluish or purplish discoloration of the cervix, vagina, and vulva caused by increased blood flow to the pelvic area during pregnancy. It is one of the earliest signs of pregnancy and can be observed as early as six to eight weeks of gestation.

Choice B Reason: This is incorrect because Goodell's sign is a softening of the cervix due to increased vascularity and edema during pregnancy. It is another early sign of pregnancy and can be detected by palpation around six to eight weeks of gestation.

Choice C Reason: This is incorrect because Hegar's sign is a softening of the lower uterine segment or isthmus during pregnancy. It is also an early sign of pregnancy and can be felt by bimanual examination around six to twelve weeks of gestation.

Choice D Reason: This is incorrect because Homan's sign is a pain in the calf or popliteal region when the foot is dorsiflexed. It is a sign of deep vein thrombosis, which is a potential complication of pregnancy, but not a normal finding.
