A nurse on the labor and delivery unit is caring for a client following a vaginal examination by the provider which is documented as: -1. Which of the following interpretations of this finding should the nurse make?
The cervix is effaced 1 cm.
The presenting part is 1 cm above the ischial spines.
The cervix is 1 cm dilated.
The presenting part is 1 cm below the ischial spines.
The Correct Answer is B
The correct answer is choice B.
Choice A rationale:
The term “-1” in a vaginal examination does not refer to the effacement of the cervix. Effacement is usually expressed as a percentage.
Choice B rationale:
In a vaginal examination, “-1” refers to the station of the fetus. A “-1” station means that the presenting part of the fetus (usually the head) is 1 cm above the ischial spines.
Choice C rationale:
The term “-1” in a vaginal examination does not refer to the dilation of the cervix. Dilation is usually measured in centimeters, from 0 (no dilation) to 10 (fully dilated).
Choice D rationale:
A “-1” station does not mean that the presenting part is below the ischial spines. It means that it is above the ischial spines.

Correct Answer is D
Explanation
The correct answer is choice D.
Choice A rationale:
Superficial structures above the muscle refer to first-degree lacerations, which only involve the skin of the perineum and vaginal mucosa.
Choice B rationale:
A fourth-degree laceration does not stop at the anterior rectal wall. It extends through the anal sphincter and into the rectal mucosa.
Choice C rationale:
While a fourth-degree laceration does involve the anal sphincter muscle, it also includes the underlying rectal mucosa.
Choice D rationale:
A fourth-degree laceration involves the perineal muscles, the anal sphincter, and the underlying rectal mucosa.
Correct Answer is D
Explanation
The correct answer is choice D.
Choice A rationale:
Cervix dilation of 5 cm with 50% effacement is a sign of active phase of the first stage of labor, not the end of it.
Choice B rationale:
Rupturing of fetal membranes can occur at any time during labor, not specifically at the end of the first stage.
Choice C rationale:
Start of regular contractions is a sign of the onset of labor, not the end of the first stage.
Choice D rationale:
Cervix dilation of 10 cm with 100% effacement indicates the end of the first stage of labor and the beginning of the second stage.
