Assessment of a woman in labor reveals that the fetus is in a cephalic presentation and engagement has occurred.
The nurse interprets this finding to indicate that the presenting part is at which station?.
-2.
+1.
0.
-1.
-1.
The Correct Answer is C
Choice A rationale:
Station -2 means the presenting part is 2 cm above the ischial spines. Engagement usually occurs at 0 station.
Choice B rationale:
Station +1 means the presenting part is 1 cm below the ischial spines. This usually occurs during labor, not necessarily at engagement.
Choice C rationale:
Station 0 means the presenting part is at the level of the ischial spines. This is typically when engagement occurs.
Choice D rationale:
Station -1 means the presenting part is 1 cm above the ischial spines. Engagement usually occurs at 0 station.

Correct Answer is ["B","C","D","E"]
Explanation
Choice A rationale:
The vagina is not part of the true pelvis. It is the canal that leads from the uterus to the exterior of the body.
Choice B rationale:
The pelvic inlet is the upper part of the lesser pelvis where the baby’s head engages during labor. It is part of the true pelvis.
Choice C rationale:
The pelvic outlet is the lower opening of the pelvis. It is part of the true pelvis.
Choice D rationale:
The mid pelvis is the part of the pelvis where the baby turns to get into the right position for birth. It is part of the true pelvis.
Choice E rationale:
The pelvic floor muscles support the pelvic organs and help in the process of childbirth. They are part of the true pelvis.
Choice F rationale:
The cervix is the lower part of the uterus that opens into the vagina. It is not part of the true pelvis. So, the correct answers are B, C, D, and E.
Correct Answer is A
Explanation
Choice A rationale:
Cervical dilation is the major change occurring during the first stage of labor. This stage begins with the onset of labor and ends when the cervix is fully dilated.
Choice B rationale:
Fetal movement through the birth canal primarily occurs during the second stage of labor, not the first.
Choice C rationale:
Placental separation occurs during the third stage of labor, after the baby is born.
Choice D rationale:
Regular contractions do occur during the first stage of labor, but they are not the major change. The major change is cervical dilation.
