A 32-year-old primigravida is admitted with a diagnosis of ectopic pregnancy. Nursing care is based on the knowledge that:

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.

Choice A reason: This is not the correct action, as the rate is not within normal limits. A normal FHR at 30 weeks of gestation is between 110 and 160 beats/min. A rate of 82 beats/min is considered bradycardia (slow heart rate), which can indicate fetal distress or hypoxia (low oxygen).

Choice B reason: This is not the first action, but it may be necessary after confirming the FHR. The nurse should first rule out the possibility of a maternal-fetal heart rate confusion, which can occur when the maternal heart rate is mistakenly counted as the FHR. This can happen if the Doppler or the electronic fetal monitor is placed too close to the maternal pulse or if the maternal heart rate is unusually slow².

Choice C reason: This is the correct action, as it can help differentiate between the maternal and the fetal heart rate. The nurse should assess the woman's radial pulse at the same time as listening to the FHR and compare the rates and rhythms. If the rates are the same or very close, it is likely that the nurse is hearing the maternal heart rate instead of the FHR. If the rates are different, it is likely that the nurse is hearing the FHR and that the fetus has bradycardia.

Choice D reason: This is not the correct action, as it may cause unnecessary anxiety or distress for the woman. The nurse should not allow the woman to hear the heartbeat until the FHR is confirmed and the cause of the bradycardia is determined. The nurse should also explain the situation to the woman and provide reassurance and support.
