What is the largest diameter of the fetal skull?
- A. Temporal
- B. Biparietal

- B. Are always regular.
- C. Do not dilate the cervix.

Using Leopold maneuvers to assess fetal position the nurse finds a soft rounded prominence at the level of the fundus a hard round prominence just above the symphysis pubis and nodulations on the left side of the uterus. How should the nurse document the fetal position?
- A. Right occiput anterior (ROA) vertex
- B. Left occiput anterior (LOA) vertex
- C. Right occiput transverse (ROT) breech
- D. Left occiput anterior (LOA) breech
Correct Answer: A
Rationale: Fetal position can be determined by the Leopold maneuver, which defines the relationship of the presenting part to the maternal pelvis quadrant. A soft rounded prominence at the level of the fundus, a hard round prominence just above the symphysis pubis, and nodulations on the left side of the uterus indicate a right occiput anterior (ROA), vertex positioning.
What method is used to visualize soft tissue and to determine adequacy of the pelvis with no detrimental effects to the fetus?
- A. Pelvimetry
- B. Palpation
- C. Ultrasonography
- D. X-ray
Correct Answer: C
Rationale: In more than 20 years of use, ultrasonography has had no detrimental effects on the fetus. Pelvimetry and x-ray uses radiation to visualize bony prominences. Pelvimetry is not used in the pregnant patient due to detrimental effects to the fetus. Palpation does not allow for visualization of soft tissue.
