What is the cause of early decelerations in the fetal heart rate (FHR) of a laboring woman?
Cerebral compression
Cord compression
Uteroplacental insufficiency
Spontaneous rupture of membranes
The Correct Answer is A
Choice A reason: Cerebral compression is the cause of early decelerations, as it reflects the fetal head compression during uterine contractions. Early decelerations are decreases in the FHR that begin and end with the onset and end of a contraction, respectively. They are symmetrical and mirror the shape of the contraction. Early decelerations are normal and benign, as they indicate that the fetus is responding to the increased intracranial pressure and maintaining adequate oxygenation.
Choice B reason: Cord compression is not the cause of early decelerations but of variable decelerations. Variable decelerations are abrupt and irregular decreases in the FHR that vary in onset, duration, and depth. They are usually caused by the umbilical cord being compressed or occluded by the fetal body, the maternal pelvis, or the uterine contractions. Variable decelerations can indicate fetal distress or hypoxia, especially if they are severe, frequent, or prolonged.
Choice C reason: Uteroplacental insufficiency is not the cause of early decelerations, but of late decelerations. Late decelerations are decreases in the FHR that begin after the peak of a contraction and return to the baseline after the contraction ends. They are symmetrical and have a gradual onset and recovery. They are usually caused by the reduced blood flow and oxygen delivery to the placenta and the fetus due to maternal or fetal factors. Late decelerations can indicate fetal distress or hypoxia, and require immediate intervention.
Choice D reason: Spontaneous rupture of membranes is not the cause of early decelerations, but it can be a risk factor for cord compression and variable decelerations. Spontaneous rupture of membranes is the breaking of the amniotic sac and the release of the amniotic fluid, which usually occurs during labor or shortly before it. Spontaneous rupture of membranes can cause the umbilical cord to prolapse or slip into the vagina, where it can be compressed or kinked by the fetal head or the contractions.

Correct Answer is A
Explanation
Choice A reason: Intense abdominal pain is the most prevalent clinical manifestation of abruptio placentae, as it indicates the detachment of the placenta from the uterine wall and the bleeding into the uterine muscle. The pain can be localized or diffuse, and it can be constant or intermittent. The pain can also radiate to the back or the shoulder.
Choice B reason: Cramping is not the most prevalent clinical manifestation of abruptio placentae, as it is not specific to the condition. Cramping can occur in normal pregnancy or in other complications such as preterm labor, infection, or cervical insufficiency.
Choice C reason: Uterine activity is not the most prevalent clinical manifestation of abruptio placentae, as it is not specific to the condition. Uterine activity can occur in normal pregnancy or in other complications such as preterm labor, infection, or placenta previa.
Choice D reason: Bleeding is not the most prevalent clinical manifestation of abruptio placentae, as it may or may not be present. Bleeding can be concealed or revealed, depending on the location and extent of the placental separation. Concealed bleeding occurs when the blood is trapped behind the placenta and does not exit the vagina. Revealed bleeding occurs when the blood passes through the cervix and exits the vagina.
Correct Answer is D
Explanation
Choice A reason: Asking the woman to reschedule the appointment for the examination is not the best response, as it may delay the detection and treatment of any potential problems. The nurse should inform the woman about the possible effect of the vaginal cream on the Pap test and offer her the option to reschedule or proceed with the examination.
Choice B reason: Asking the woman to describe the symptoms that indicate to her that she has a vaginal infection is a good way to assess the woman's condition and provide education, but it is not the initial response. The nurse should first inform the woman about the possible effect of the vaginal cream on the Pap test and then ask her about her symptoms.
Choice C reason: Reassuring the woman that using vaginal cream is not a problem for the examination is not true, as vaginal creams can alter the pH of the vaginal environment and affect the accuracy of the Pap test. The nurse should inform the woman about the possible effect of the vaginal cream on the Pap test and explain the importance of avoiding vaginal creams, douches, or intercourse for 48 hours before the test.
Choice D reason: Informing the woman that vaginal creams may interfere with the Pap test for which she is scheduled is the best response, as it educates the woman about the purpose and procedure of the Pap test and allows her to make an informed decision about whether to reschedule or proceed with the examination. The nurse should also explain the risks and benefits of both options and respect the woman's choice.
