A patient admitted to the labor unit asks the nurse to discuss the episiotomy procedure with her. Which is true regarding episiotomy?
- A. An episiotomy is required for all vaginal births.
- B. A midline episiotomy is associated with more third- and fourth-degree lacerations.
- C. A mediolateral episiotomy is easier to repair than a medial episiotomy.
- D. A midline episiotomy is associated with more blood loss.
Correct Answer: B
Rationale: A midline episiotomy is not required for all vaginal births, but it is associated with more third- and fourth-degree lacerations.

The onset of labor is multifactorial. These reasons include which of the following? Select all that apply.
- A. Increase in progesterone
- B. Increase in estrogen
- C. Increase in human chorionic gonadotropin
- D. Aging of placenta
Correct Answer: B
Rationale: Increase in progesterone, estrogen, aging of placenta, and fetal hormones are the factors contributing to the onset of labor.
Which assessment finding indicates that cervical dilation and/or effacement has occurred?
- A. Onset of irregular contractions
- B. Cephalic presentation at 0 station
- C. Bloody mucus drainage from vagina
- D. Fetal heart tones (FHTs) present in the lower right quadrant
Correct Answer: C
Rationale: Bloody mucus drainage from the vagina, also known as "bloody show," is a common sign that indicates cervical dilation and/or effacement has occurred in anticipation of labor. This occurs as the mucus plug, which seals the cervix during pregnancy, is released as the cervix begins to soften, dilate, and efface in preparation for childbirth. This physical change in the cervix is a significant indicator that labor is approaching. The other options listed do not directly indicate cervical changes associated with labor progression like the presence of bloody mucus drainage does.
Which is the best explanation for the use of hydration and relaxation in the treatment of hypertonic labor?
- A. Hydration promotes uterine relaxation by diluting endogenous oxytocin.
- B. Hydration improves uterine coordination by increasing perfusion.
- C. Hydration encourages contraction regulation by stimulating catecholamine release.
- D. Hydration stimulates the production of prostaglandins to relax the uterus.
Correct Answer: A
Rationale: Hydration helps to dilute endogenous oxytocin, which can reduce uterine contractions and relax the uterus. Hypertonic labor involves excessive uterine contractions, and hydration can counteract this by regulating contractions and improving perfusion, which ultimately aids in a more coordinated and effective labor progression.
A nurse performs a vaginal examination on her patient in early labor and determines that the head is ballotable. What is this defined as?
- A. Floating
- B. Zero station
- C. +1 station
- D. -2 station
Correct Answer: A
Rationale: Ballotable means the fetal head is floating and can be pushed away from the cervix.
A fetus is positioned in the occiput anterior position. The nurse determines that the fetus is positioned in which way?
- A. The fetal shoulder is closest to the vaginal opening.
- B. The fetal head is closest to the vaginal opening and the occiput is directed toward the maternal symphysis.
- C. The fetal head is closest to the uterine fundus and is directed toward the maternal symphysis.
- D. The fetal head is closest to the vaginal opening and is directed toward the maternal sacrum.
Correct Answer: B
Rationale: The occiput anterior position means the fetal head is closest to the vaginal opening, and the occiput is directed toward the maternal symphysis.
