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.

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.
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.

- 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 for optimal fetal positioning and descent. It also helps relieve pressure on the cervix, promoting dilation. Ambulation (A) may slow down labor progress, squatting (B) can increase pressure on the cervix and hinder descent, and resting on hands and knees (D) may not be as conducive to gravity-assisted descent.
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. During active labor, intermittent auscultation should be performed every 15 minutes for low-risk women without complications. This frequency allows for close monitoring of fetal well-being while also promoting a woman-centered approach to labor care. Choices B, C, and D are incorrect because they do not align with the standard guidelines for IA frequency during active labor. Every 5 minutes (B) is too frequent and may disrupt the woman's labor progress. Every 20 minutes (C) and every 30 minutes (D) are too far apart to ensure adequate monitoring of the fetal heart rate. Thus, choice A is the most appropriate option for 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. Nullipara refers to a woman giving birth for the first time, while multipara refers to a woman who has given birth multiple times. The primary difference between their labors is the total duration. Nulliparas typically have longer labors due to the body's first experience with childbirth. The other choices (B, C, D) are not the primary difference between nullipara and multipara labors. Pain experience, cervical dilation, and labor mechanisms can vary based on individual factors, but the key distinction lies in the overall duration of labor based on parity.
