What is the result of a nonstress test (NST) in which two or more fetal heart rate (FHR) accelerations of 15 beats/min or more occur with fetal movement in a 20-minute period?
Nonreactive
Reactive
Positive
Negative
The Correct Answer is B
Choice A reason: Nonreactive is not the correct result, as it indicates that the FHR does not show adequate accelerations with fetal movement. A nonreactive NST means that the FHR does not increase by at least 15 beats/min for at least 15 seconds in a 20-minute period. A nonreactive NST may suggest fetal hypoxia (low oxygen) or fetal sleep.
Choice B reason: Reactive is the correct result, as it indicates that the FHR shows adequate accelerations with fetal movement. A reactive NST means that the FHR increases by at least 15 beats/min for at least 15 seconds twice or more in a 20-minute period. A reactive NST is reassuring and suggests that the fetus is well-oxygenated and healthy.
Choice C reason: Positive is not the correct result, as it is not used to describe the NST. Positive is a term used for the contraction stress test (CST), which is a different test that measures the FHR in response to uterine contractions. A positive CST means that the FHR shows late decelerations (decreases in the FHR that begin after the peak of a contraction and return to the baseline after the contraction ends) with at least 50% of the contractions. A positive CST indicates uteroplacental insufficiency (a condition where the placenta does not deliver enough oxygen and nutrients to the fetus) and fetal distress.
Choice D reason: Negative is not the correct result, as it is also not used to describe the NST. Negative is another term used for the CST, which is a different test that measures the FHR in response to uterine contractions. A negative CST means that the FHR does not show any late decelerations during at least three contractions in a 10-minute period. A negative CST is reassuring and suggests that the fetus is well-oxygenated and can tolerate labor.

Correct Answer is A
Explanation
The correct answer is A. You may find that you need to modify your exercise to walking later in your pregnancy, around the seventh month.
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 actually 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 ["B","C","E"]
Explanation
Choice A reason: Urinary frequency is a common symptom of pregnancy, especially in the first and third trimesters, due to the increased pressure of the uterus on the bladder. It is not a sign of complication and does not need to be reported immediately.
Choice B reason: Rupture of membranes is the breaking of the amniotic sac, which can occur spontaneously or artificially before or during labor. It is a sign of impending delivery and can increase the risk of infection. It should be reported immediately to the health care provider.
Choice C reason: Heartburn accompanied by severe headache can indicate preeclampsia, a serious condition characterized by high blood pressure and proteinuria in pregnancy. It can lead to eclampsia, which is a life-threatening seizure disorder. It should be reported immediately to the health care provider.
Choice D reason: Decreased libido is a normal change in pregnancy, due to hormonal fluctuations, physical discomfort, and emotional stress. It is not a sign of complication and does not need to be reported immediately.
Choice E reason: Vaginal bleeding can indicate various complications in pregnancy, such as placenta previa, placental abruption, or miscarriage. It can pose a threat to the mother and the fetus. It should be reported immediately to the health care provider.
