When does the active phase of labor begin according to ACOG?
- A. 6 cm
- B. 3 cm
- C. 5 cm
- D. 10 cm
Correct Answer: A
Rationale: The active phase of labor begins at 6 cm dilation according to ACOG guidelines. At this point, the cervix is significantly dilated, signaling the transition to active labor. This stage is crucial as it signifies the acceleration of labor progress and typically involves stronger contractions leading to efficient cervical dilation. Choices B, C, and D are incorrect as they do not align with the established criteria for the active phase of labor. Choice B (3 cm) is too early for active labor, choice C (5 cm) is close but not quite at the threshold for active labor, and choice D (10 cm) is actually the full dilation stage, not the beginning of active labor. Hence, choice A (6 cm) is the correct answer.

A woman’s pelvis is described as long and narrow with an anteroposterior diameter greater than the transverse diameter. This is known as which type of pelvis?
- A. Platypelloid
- B. Android
- C. Anthropoid
- D. Gynecoid
Correct Answer: C
Rationale: The correct answer is C: Anthropoid. In an anthropoid pelvis, the anteroposterior diameter is greater than the transverse diameter, giving it a long and narrow shape. This type of pelvis resembles the pelvis seen in higher primates. The other choices are incorrect because:
A: Platypelloid pelvis has a transversely wide and short shape.
B: Android pelvis has a heart-shaped inlet with a prominent sacrum and narrow pubic arch.
D: Gynecoid pelvis has a round inlet and a wide pubic arch, typically seen in females and ideal for childbirth.
What anticipatory guidance should the nurse provide for new parents regarding sociologic changes?
- A. Explain that roles will not change at home
- B. Explain that stresses will be over now that the newborn is born.
- C. Tell the parents not to stress over household changes.
- D. Prepare them for possible strains on relationships.
Correct Answer: D
Rationale: The correct answer is D: Prepare them for possible strains on relationships. This guidance is important as the arrival of a newborn can bring significant changes to the dynamics of a relationship. By preparing new parents for possible strains on relationships, the nurse can help them navigate challenges together.
A: Incorrect. Roles are likely to change at home with the addition of a newborn, so it is important to address this rather than dismissing it.
B: Incorrect. Stressors may actually increase with the arrival of a newborn, so it is not accurate to say stresses will be over.
C: Incorrect. Ignoring household changes can lead to added stress, so it is not advisable to tell parents not to stress over them.
In summary, option D is correct as it addresses the potential strains on relationships that new parents may face, while the other options do not acknowledge the reality of sociologic changes that can occur.
A woman’s pelvis is described as long and narrow with an anteroposterior diameter greater than the transverse diameter. This is known as which type of pelvis?
- A. Platypelloid
- B. Android
- C. Anthropoid
- D. Gynecoid
Correct Answer: C
Rationale: The correct answer is C: Anthropoid. An anthropoid pelvis is characterized by a long and narrow shape with an anteroposterior diameter greater than the transverse diameter. This type of pelvis resembles the pelvic structure of anthropoid (higher primates) mammals. The other choices are incorrect because:
A: Platypelloid pelvis is flat and broad, not long and narrow.
B: Android pelvis has a heart-shaped inlet with an android appearance, not a long and narrow shape.
D: Gynecoid pelvis is rounded and wider with a transverse diameter greater than the anteroposterior diameter, opposite of the described characteristics.
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.
The nurse midwife caring for a multiparous client who is 5 cm dilated requests intermittent auscultation (IA) of the fetal heart rate. The woman’s history reveals no risk factors. How often should IA be performed in this patient?
- A. Every 15 minutes
- B. Every 5 minutes
- C. Every 20 minutes
- D. Every 30 minutes
Correct Answer: A
Rationale: The correct answer is A: Every 15 minutes. This frequency is recommended for a low-risk multiparous client in active labor without risk factors. Intermittent auscultation every 15 minutes allows for adequate monitoring of fetal well-being while also promoting maternal autonomy and mobility. Choices B, C, and D are incorrect because they are either too frequent or too infrequent for a low-risk client in active labor. Every 5 minutes (B) may be excessive and disrupt the labor process, every 20 minutes (C) may not provide sufficient monitoring, and every 30 minutes (D) may not detect changes in fetal status promptly.
