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.

Which factor ensures that the smallest anterior-posterior diameter of the fetal head enters the pelvis?
- A. Station
- B. Flexion
- C. Descent
- D. Engagement
Correct Answer: B
Rationale: Flexion is the correct answer. During labor, fetal head flexion allows the smallest anterior-posterior diameter of the head to enter the pelvis first, reducing the risk of cephalopelvic disproportion. Station refers to the level of the presenting part in the maternal pelvis, not the head orientation. Descent is the downward movement of the fetus in the birth canal, not related to head position. Engagement occurs when the widest part of the presenting part reaches the level of the maternal ischial spines, not specifically related to the orientation of the fetal head.
A 28-year-old gravida 1, para 0 patient who is at term calls the labor and birth unit stating that she thinks she is in labor. She states that she does have some vaginal discharge and feels wet;
- A. She relates a contraction pattern that is irregular, ranging from 5 to 7 minutes and lasting 30 seconds. Which questions should the nurse pose to the patient during this telephone triage? (Select all that apply.)
- B. Does she think that her membranes have ruptured?
- C. Is there any evidence of bloody show?
- D. Instruct the patient to keep monitoring her contraction pattern and call you back if they become more regular.
Correct Answer: A
Rationale: The correct answer is A because the patient's irregular contraction pattern and timing indicate early labor. The nurse should ask about the frequency, duration, and intensity of contractions to assess progression. Choices B and C focus on specific signs of labor but do not address the need for continuous monitoring and assessment like choice A does. Choice D does not address the need to gather specific information about the contraction pattern to determine the appropriate next steps. Therefore, A is the correct choice as it directly addresses the patient's current situation and provides guidance on what information is necessary for appropriate triage.
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: The correct answer is D: pattern of uterine contractions. This is because the pattern of contractions is a key indicator of true labor. True labor contractions are regular, increasing in frequency, duration, and intensity. Assessing the pattern helps differentiate true labor from false labor.
A: Cervical dilation is important but may not necessarily indicate true labor as it can occur in false labor as well.
B: The amount of bloody show is a sign of cervical changes, but it alone does not confirm true labor.
C: Fetal position and station are important for labor progress but do not definitively confirm true labor.
In summary, assessing the pattern of uterine contractions is crucial in determining true labor as it provides direct insight into the progression and intensity of contractions, distinguishing it from false labor.
How long is the expected length of the third stage of labor?
- A. 60 minutes or less
- B. 30 minutes or less
- C. 1 hour for a multiparous person, 2 hours for a nulliparous person
- D. 3 hours for a multiparous person, 4 hours for a nulliparous person
Correct Answer: C
Rationale: The correct answer is C: 1 hour for a multiparous person, 2 hours for a nulliparous person. This is based on the typical duration of the third stage of labor, which involves the delivery of the placenta. In general, the third stage is expected to last around 5-30 minutes. However, for safety reasons and to allow for variations in individual cases, it is recommended to extend the time frame to 1 hour for multiparous individuals (those who have given birth before) and 2 hours for nulliparous individuals (those giving birth for the first time). This extended time frame ensures that healthcare providers have enough time to monitor and intervene if necessary without rushing the delivery of the placenta.
Other choices are incorrect because they provide either too short (A and B) or too long (D) timeframes for the third stage of labor, which could lead to inadequate monitoring or unnecessary interventions.
