Signs and symptoms that a pregnant woman should report immediately to her health care provider include: (Select all that apply.)

The correct answer is d. Amenorrhea.

Choice A: Chadwick’s sign is a non-specific, early sign of pregnancy that is typically characterized by a bluish discoloration of the cervix, vagina, and vulva. The Chadwick sign can typically be observed as early as six to eight weeks after conception, and commonly disappears shortly after birth. However, it’s not a definitive indication of pregnancy, and the absence of it on physical exam does not exclude a potential pregnancy.

Choice B: Hegar’s sign is a non-specific indication of pregnancy that is characterized by the compressibility and softening of the cervical isthmus (i.e., the portion of the cervix between the uterus and the vaginal portion of the cervix). It typically presents between the fourth and sixth week of pregnancy and may be present until the 12th week of pregnancy. However, the Hegar sign is not a definitive indication of pregnancy, and the absence of it does not exclude a potential pregnancy.

Choice C: A positive pregnancy test By 10 weeks, a home pregnancy test would almost certainly show a positive result if the woman is pregnant. This is because the hormone human chorionic gonadotropin (hCG), which is produced by the placenta after implantation of the embryo into the uterine wall, would be present in high enough levels to be detected by the test. However, a positive pregnancy test is not a presumptive sign of pregnancy, but rather a probable one.

Choice D: Amenorrhea, or the absence of menstrual periods, is often considered the most presumptive sign of pregnancy. This is because it’s one of the first noticeable signs of pregnancy for many women. By 10 weeks of gestation, the woman would likely have missed two menstrual periods if she usually has regular cycles. However, while amenorrhea is a common early sign of pregnancy, it can also be caused by various other conditions or factors such as stress, significant weight loss or gain, or certain medical conditions. Therefore, a missed period should be followed up with a pregnancy test to confirm pregnancy.

Choice A reason: Seizure activity and hypotension are not signs and symptoms of severe preeclampsia, but rather of eclampsia, which is a life-threatening complication of preeclampsia. Eclampsia is characterized by convulsions and coma, and it requires immediate treatment to prevent maternal and fetal death.

Choice B reason: Platelet count of less than 100,000/mm3 and visual problems are signs and symptoms of severe preeclampsia, as they indicate hematologic and neurologic complications. Severe preeclampsia can cause thrombocytopenia, which is a low platelet count that increases the risk of bleeding. It can also cause cerebral edema, which can impair the vision and cause blurred vision, spots, or flashes of light.

Choice C reason: Ankle clonus and epigastric pain are signs and symptoms of severe preeclampsia, as they indicate neuromuscular and hepatic complications. Severe preeclampsia can cause hyperreflexia, which is an exaggerated reflex response that can be elicited by dorsiflexing the ankle and observing rhythmic jerking of the foot. It can also cause liver damage, which can manifest as epigastric pain or right upper quadrant pain.

Choice D reason: Decreased urinary output and irritability are signs and symptoms of severe preeclampsia, as they indicate renal and central nervous system complications. Severe preeclampsia can cause oliguria, which is a reduced urine output of less than 500 mL in 24 hours. It can also cause increased intracranial pressure, which can affect the mood and behavior and cause irritability, anxiety, or confusion.

Choice E reason: Transient headache and +1 proteinuria are not signs and symptoms of severe preeclampsia, but rather of mild preeclampsia, which is a less severe form of the condition. Mild preeclampsia is characterized by blood pressure of 140/90 mm Hg or higher, proteinuria of 1+ or higher, and mild edema. It does not cause severe complications or organ damage, but it can progress to severe preeclampsia if not treated.
