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: The correct answer is C because the multigravida uterus has undergone labor before, making muscle coordination more efficient. This allows for faster and more coordinated contractions, leading to precipitous labor. Choice A is incorrect because the cervix does not weaken after each delivery. Choice B is incorrect as simultaneous dilation and effacement are not specific to multiparous women. Choice D is incorrect because the ability to recognize labor onset is not a determining factor in the occurrence of precipitous labor.

Arrange the seven cardinal movements of labor, in order.
- A. Descent
- B. Expulsion
- C. Extension
- D. External rotation
Correct Answer: A
Rationale: The correct order of the seven cardinal movements of labor is: Descent, Flexion, Internal Rotation, Extension, Restitution, External Rotation, and Expulsion. Descent is the first cardinal movement, as the baby moves down the birth canal. Flexion follows to allow the baby's head to pass through the pelvis. Internal Rotation, Extension, and Restitution then occur to facilitate the baby's shoulders and body turning in alignment with the mother's pelvis. External Rotation follows to help the shoulders rotate to the correct position for delivery. Finally, Expulsion is when the baby is born. This sequence ensures a smooth and safe delivery. The other choices are incorrect as they are not part of the specific sequence of cardinal movements during labor.
What changes in hormones initiate labor?
- A. decreased progesterone, decreased estrogen, absence of oxytocin
- B. increased progesterone, decreased estrogen, absence of oxytocin
- C. increased progesterone, decreased estrogen, presence of oxytocin
- D. decreased progesterone, increased estrogen, effects of oxytocin
Correct Answer: D
Rationale: The correct answer is D because decreased progesterone, increased estrogen, and the effects of oxytocin are the hormonal changes that initiate labor. Progesterone inhibits contractions, so its decrease allows labor to begin. Estrogen promotes uterine sensitivity to oxytocin, which stimulates contractions. Oxytocin is released in response to labor contractions and helps to strengthen contractions.
A: Incorrect because decreased progesterone is needed for labor to start, estrogen needs to increase, and oxytocin is present during labor.
B: Incorrect because increased progesterone inhibits labor, estrogen should increase, and oxytocin is present during labor.
C: Incorrect because progesterone should decrease, estrogen should increase, and oxytocin is present during labor.
A 35-year-old gravida 1, para 0 is admitted to the labor and delivery unit. She reports intense rectal pressure. Which stage of labor is probable?
- A. First stage, latent
- B. Second stage
- C. Third stage
- D. Fourth stage
Correct Answer: B
Rationale: The correct answer is B: Second stage. This stage of labor is characterized by full dilation of the cervix and ends with the delivery of the baby. The intense rectal pressure reported by the patient indicates that the baby is descending through the birth canal, which is a hallmark sign of the second stage. In contrast, the first stage, latent (choice A) is characterized by early labor contractions and cervical dilation up to 6 cm. The third stage (choice C) is the delivery of the placenta, and the fourth stage (choice D) is the immediate postpartum period. The key here is recognizing the specific symptom of intense rectal pressure, which aligns with the second stage of labor.
A 28-year-old woman without risk factors has now reached the second stage of labor. What is the optimal position for her at this point?
- A. Supine
- B. Lateral recumbent
- C. Lithotomy
- D. Squatting
Correct Answer: B
Rationale: The optimal position for a woman in the second stage of labor is lateral recumbent. This position allows gravity to aid in the descent of the baby, reduces pressure on the vena cava, and promotes better blood flow to the uterus. It also helps prevent perineal tears and facilitates fetal rotation.
A: Supine position can compress the vena cava, reducing blood flow to the uterus.
C: Lithotomy position is not recommended as it can lead to increased perineal trauma.
D: Squatting may not be ideal as it can be tiring for the mother and may not provide optimal support for delivery.
To determine if the patient is in true labor, the nurse would assess for changes in
- A. cervical dilation.
- B. amount of bloody show.
- C. fetal position and station.
- D. pattern of uterine contractions.
Correct Answer: D
Rationale: Step-by-step rationale:
1. The pattern of uterine contractions is crucial in determining true labor as true contractions are regular, increasing in frequency, duration, and intensity.
2. Assessing cervical dilation alone may not confirm true labor as some women may have cervical changes without being in active labor.
3. Bloody show may occur in both true and false labor, making it an unreliable indicator.
4. Fetal position and station are important for labor progression but do not definitively confirm true labor.
Therefore, by assessing the pattern of uterine contractions, the nurse can accurately determine if the patient is in true labor.
