A woman at 10 weeks of gestation who is seen in the prenatal clinic with presumptive signs and symptoms of pregnancy likely will have?
Chadwick's sign.
Hegar's sign.
a positive pregnancy test.
amenorrhea.
The Correct Answer is D
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.

Correct Answer is A
Explanation
Choice A reason: This is the best advice for the woman, as it acknowledges that jogging is safe and beneficial in early pregnancy, but also informs her that she may need to adjust her exercise intensity and duration as her pregnancy progresses. Walking is a low-impact aerobic activity that can be done throughout pregnancy, as long as there are no complications or contraindications. Walking can help maintain cardiovascular fitness, prevent excessive weight gain, and reduce the risk of gestational diabetes and preeclampsia.
Choice B reason: This is not a good advice for the woman, as it implies that jogging is harmful for her joints and that she should stop it immediately. Jogging is not necessarily bad for the joints, as long as the woman wears appropriate shoes, avoids uneven surfaces, and listens to her body. Jogging can also provide many health benefits for the woman and the fetus, such as improved mood, increased energy, and reduced stress².
Choice C reason: This is a false and alarming statement that may discourage the woman from exercising at all. Exercise during pregnancy is not dangerous for the fetus unless there are specific medical conditions or complications that prevent it. Exercise during pregnancy can improve the fetal growth, development, and oxygenation, as well as reduce the risk of preterm birth and low birth weight.
Choice D reason: This is an unrealistic and misleading statement that may cause the woman to overexert herself or ignore the signs of discomfort or fatigue. Exercise during pregnancy may need to be modified according to the woman's changing needs, abilities, and preferences. Some factors that may affect the type, frequency, intensity, and duration of exercise during pregnancy include the trimester, the fetal position, the maternal weight, the environmental temperature, and the presence of any symptoms or complications.
Correct Answer is D
Explanation
Choice A reason: Biophysical profile is a test that assesses the fetal well-being by measuring five parameters: fetal breathing movements, fetal movements, fetal tone, amniotic fluid volume, and fetal heart rate. It does not predict chromosomal abnormalities in the fetus.
Choice B reason: Lecithin/sphingomyelin [L/S] ratio is a test that measures the amount of two phospholipids in the amniotic fluid. It is used to evaluate the fetal lung maturity and the risk of respiratory distress syndrome. It does not predict chromosomal abnormalities in the fetus.
Choice C reason: Type and crossmatch of maternal and fetal serum is a test that determines the blood type and Rh factor of the mother and the fetus. It is used to identify the risk of hemolytic disease of the newborn due to Rh incompatibility. It does not predict chromosomal abnormalities in the fetus.
Choice D reason: Multiple-marker screening is a test that measures the levels of four substances in the maternal serum: alpha-fetoprotein, human chorionic gonadotropin, unconjugated estriol, and inhibin A. It is used to estimate the risk of Down syndrome, trisomy 18, and neural tube defects in the fetus.
