high risk labor and delivery nclex questions Questions
Question 1 of 5
Which is the cervical exam that most indicates the use of misoprostol?
Correct Answer: A
Rationale: Step 1: Misoprostol is a medication used for cervical ripening and induction of labor. Step 2: The characteristics of the cervix that indicate the need for misoprostol are early in the dilation process (1 cm dilated), minimally effaced (20%), high station (-3), and firm and posterior position. Step 3: Choice A best aligns with these characteristics, making it the correct answer. Step 4: Choices B, C, and D are more advanced in dilation, effacement, station, and cervical position which do not indicate the need for misoprostol.
Question 2 of 5
The patient with which vaginal exam is most at risk for an umbilical cord prolapse?
Correct Answer: B
Rationale: The correct answer is B because a patient who is 5 cm dilated, 60% effaced, and at -3 station is most at risk for an umbilical cord prolapse. At this stage, the presenting part of the baby is not well engaged in the pelvis, increasing the likelihood of the cord slipping down in front of the baby. This can lead to compression of the cord during labor, which is a serious obstetric emergency. Choice A is less likely as the baby is only at -1 station and not as far down in the pelvis. Choice C also has the baby at a higher station (-2) and more dilated, which may help secure the baby's position. Choice D is the least likely as the baby is fully engaged at 0 station, reducing the risk of cord prolapse.
Question 3 of 5
A gravida 2, para 1 is in active labor at 39 weeks gestation. Her cervical exam is 6 cm dilated, 60% effaced, and 0 station. An amniotomy is performed by the physician. The fluid is noted to be bloody and the fetal heart tones have decelerated to the 50s. What is the nurse’s next best action?
Correct Answer: A
Rationale: The correct answer is A: Notify the operating team of emergent cesarean delivery. Given the scenario of a gravida 2, para 1 in active labor with bloody fluid and fetal heart decelerations to the 50s following amniotomy, these signs indicate fetal distress. In this critical situation, immediate intervention with emergent cesarean delivery is necessary to prevent adverse outcomes for the baby. This step takes priority over other actions, as it ensures timely delivery and assessment of the fetus's well-being. Choices B, C, and D are not appropriate in this emergent situation as they do not directly address the fetal distress and the need for expedited delivery.
Question 4 of 5
When caring for a woman with a complete placenta previa, which finding should the nurse report to the physician?
Correct Answer: D
Rationale: The correct answer is D: O2 saturation less than 95%. In placenta previa, the placenta covers the cervix, increasing the risk of bleeding. Decreased oxygen saturation can indicate poor perfusion due to bleeding, necessitating immediate medical attention. A: BP of 95/60 is relatively normal and not an urgent concern in this scenario. B: Temperature of 100.1°F may indicate an infection but is not directly related to placenta previa. C: Urine output of 40 mL/hour is within the normal range and does not directly impact the management of placenta previa.
Question 5 of 5
What is a direct influence on cervical dilation? Select all that apply.
Correct Answer: A
Rationale: The correct answer is A: positioning of the pregnant person. The position of the pregnant person can directly influence cervical dilation by affecting the alignment of the uterus and baby, allowing for optimal pressure on the cervix. Proper positioning can facilitate the descent of the baby's head onto the cervix, promoting dilation. Summary of why other choices are incorrect: B: The strength of uterine contractions indirectly influences cervical dilation by aiding in the effacement and descent of the baby, but it does not directly impact dilation. C: The length of time since ROM (rupture of membranes) can affect the risk of infection but does not directly influence cervical dilation. D: Fetal presentation refers to the position of the baby in the uterus and can affect labor progress, but it does not directly impact cervical dilation.
