Why is precipitous labor most often seen in multiparous women?
- A. The cervix weakens after each delivery.
- B. The cervix can dilate and efface simultaneously.
- C. The multigravida uterus is better able to coordinate muscle movements.
- D. It is more difficult for multiparous women to know when labor begins.
Correct Answer: C
Rationale: Step 1: In multiparous women, the uterus has gone through labor before, making muscle coordination more efficient.
Step 2: Efficient muscle coordination helps in effective contractions, leading to faster labor progress.
Step 3: Multiparous women have experienced labor before, allowing the uterus to contract more effectively.
Step 4: This efficiency in muscle coordination is why precipitous labor is more often seen in multiparous women.
Summary:
A: The weakening of the cervix after each delivery is not a direct cause of precipitous labor.
B: The ability of the cervix to dilate and efface simultaneously does not explain why precipitous labor is more common in multiparous women.
D: The difficulty in knowing when labor begins is not a reason for the occurrence of precipitous labor in multiparous women.

Which explains why infants who are delivered via cesarean section before the start of labor have more difficulty transitioning to extrauterine life?
- A. The use of warm IV fluids precipitates hyperthermia.
- B. Regional anesthesia causes respiratory depression.
- C. The maternal left tilt position reduces placental blood flow.
- D. Residual amniotic fluid in the lungs makes spontaneous respirations difficult.
Correct Answer: D
Rationale: The correct answer is D because infants delivered via cesarean section before labor may not have had the opportunity to expel amniotic fluid from their lungs through the vaginal passage, leading to respiratory distress. This residual fluid can hinder the initiation of spontaneous respirations, causing difficulty in transitioning to extrauterine life. Choices A, B, and C are incorrect because hyperthermia from warm IV fluids, respiratory depression from regional anesthesia, and reduced placental blood flow from maternal position are not primary factors affecting the infant's ability to transition to extrauterine life in this scenario.
The primary difference between the labor of a nullipara and that of a multipara is
- A. total duration of labor.
- B. level of pain experience
- C. amount of cervical dilation.
- D. sequence of labor mechanisms.
Correct Answer: A
Rationale: The correct answer is A: total duration of labor. This is because nulliparas (women who have never given birth before) generally have longer labors compared to multiparas (women who have given birth before). This is due to factors such as the first-time stretching of the birth canal and the body's learning process. The level of pain experience (B) can vary among individuals and is not a primary difference between nulliparas and multiparas. The amount of cervical dilation (C) can be influenced by various factors and is not a defining difference between the two groups. The sequence of labor mechanisms (D) is a universal process in labor and does not differ based on whether a woman is a nullipara or multipara.
A gravida 3, para 2 is attempting a vaginal birth without the use of pain medicine or anesthesia. Following spontaneous rupture of membranes, the patient’s cervical exam was 5 cm dilated, 60% effaced, -2 station. Which therapeutic intervention is appropriate for this patient?
- A. Ambulation with assistance
- B. Squatting with support from partner
- C. Sitting on birthing ball
- D. Resting on hands and knees
Correct Answer: C
Rationale: The correct answer is C: Sitting on birthing ball. This position helps to open up the pelvis, allowing gravity to assist in descent of the baby. It also promotes optimal positioning for the baby, reducing the risk of malpresentation. The other choices (A, B, D) do not provide the same benefits in terms of promoting optimal fetal positioning and utilizing gravity to aid in labor progress. Ambulation with assistance may not provide as much support for the pelvis, squatting with support from the partner may not be as stable or comfortable for the mother, and resting on hands and knees may not encourage as much engagement of the baby's head in the pelvis.
During an oxytocin induction, which assessment finding is most concerning to the labor and delivery nurse?
- A. A uterine resting tone of 17 mm Hg
- B. A uterine resting tone of 30 mm Hg
- C. Contractions that are every 3 minutes and last 60 seconds
- D. Contractions that are every 5 minutes and last 60 seconds
Correct Answer: B
Rationale: The correct answer is B because a uterine resting tone of 30 mm Hg indicates excessive uterine activity, which can lead to uterine hyperstimulation and fetal distress during an oxytocin induction. A higher resting tone suggests the uterus is not relaxing adequately between contractions, potentially compromising fetal oxygenation. Choices A, C, and D are incorrect because a uterine resting tone of 17 mm Hg is within the normal range, contractions every 3 minutes lasting 60 seconds and every 5 minutes lasting 60 seconds are typical patterns during labor induction, and they do not necessarily indicate complications.
What should the nurse consider when the birthing person has a decrease in blood pressure after the placenta is delivered?
- A. The birthing person is in pain.
- B. Place the newborn skin-to-skin.
- C. The bladder is distended
- D. Check for possible hemorrhage.
Correct Answer: E
Rationale: Based on the scenario, the decrease in blood pressure post-placenta delivery indicates potential hemorrhage, a common complication. The nurse should assess for signs of bleeding, such as excessive vaginal bleeding or tachycardia. Prompt intervention is crucial to prevent further complications. Other choices are less relevant - pain alone does not directly cause a decrease in blood pressure, skin-to-skin contact is important but not the priority in this situation, and a distended bladder can be addressed later. Assessing for possible hemorrhage is the most critical action to take in this scenario.
