A nurse is assisting in the care of a client who is in labor.
The doctor documents the vaginal examination as: 3 cm, 30%, and -1. The nurse evaluates this documentation to
mean which of the following?
The cervix is effaced 3 cm, it is dilated 30%, and the presenting part is 1 cm above the ischial spines
The cervix is dilated 3 cm, it is effaced 30%, and the presenting part is 1 cm below the ischial spines
The cervix is dilated 3 cm, it is effaced 30%, and the presenting part is 1 cm above the ischial spines
The cervix is effaced 3 cm, it is dilated 30%, and the presenting part is 1 cm below the ischial spines
The Correct Answer is C
The correct answer is choice c. The cervix is dilated 3 cm, it is effaced 30%, and the presenting part is 1 cm above the ischial spines.
Choice A rationale:
This choice incorrectly states that the cervix is effaced 3 cm and dilated 30%. Effacement is measured in percentages, not centimeters, and dilation is measured in centimeters, not percentages.
Choice B rationale:
This choice correctly states the cervix is dilated 3 cm and effaced 30%, but it incorrectly states that the presenting part is 1 cm below the ischial spines. A station of -1 means the presenting part is 1 cm above the ischial spines.
Choice C rationale:
This choice correctly states that the cervix is dilated 3 cm, effaced 30%, and the presenting part is 1 cm above the ischial spines. This matches the documentation provided.
Choice D rationale:
This choice incorrectly states that the cervix is effaced 3 cm and dilated 30%. Effacement is measured in percentages, not centimeters, and dilation is measured in centimeters, not percentages. Additionally, it incorrectly states that the presenting part is 1 cm below the ischial spines. A station of -1 means the presenting part is 1 cm above the ischial spines.

Correct Answer is B
Explanation
Choice A is incorrect. Preterm labor is defined as uterine contractions that occur before 37 weeks of gestation. The
client in this case is at 38 weeks of gestation, which is considered term gestation. Therefore, preterm labor is not the
most likely condition the client is experiencing.
Rationale for Choice B
Choice B is partially correct. While bed rest may be recommended for some clients experiencing certain conditions
during pregnancy, it is not the most appropriate intervention for all clients at 38 weeks of gestation. Additionally,
administering medication without knowing the specific condition the client is experiencing is not safe or ethical.
Rationale for Choice C
Choice C is correct. Monitoring contraction frequency and fetal heart rate are two of the most important actions a
nurse can take to assess a client at 38 weeks of gestation. These parameters can provide valuable information about
the client's progress and help to identify any potential problems.
Explanation:
At 38 weeks of gestation, the client is considered to be at term. This means that she is full-term and her baby is ready
to be born. However, even at term, there are a number of conditions that can occur that may require nursing
intervention.
One of the most common conditions that can occur at term is labor. Labor is the process by which the uterus contracts
and dilates to push the baby out of the birth canal. The nurse should monitor the client for signs and symptoms of
labor, such as:
Regular contractions that are becoming stronger and closer together
Bloody show (mucus mixed with blood)
Rupture of membranes (breaking of water)
If the nurse suspects that the client is in labor, she should notify the healthcare provider immediately.
Another condition that can occur at term is preeclampsia. Preeclampsia is a serious condition that can cause high
blood pressure, protein in the urine, and swelling in the face, hands, and feet. If the nurse suspects that the client has
preeclampsia, she should monitor the client's blood pressure, protein levels in the urine, and weight. She should also
notify the healthcare provider immediately.
In addition to monitoring for these specific conditions, the nurse should also perform a general assessment of the
client's health. This includes taking the client's vital signs, checking her abdomen for fetal movement, and listening to
the baby's heartbeat.
By monitoring the client for signs and symptoms of these conditions, the nurse can help to ensure a safe and healthy
delivery for both the mother and the baby.
Therefore, the two most important actions the nurse should take are:
Monitor the client for signs and symptoms of labor and preeclampsia.
Perform a general assessment of the client's health.
The two most important parameters the nurse should monitor are:
Contraction frequency and intensity
Fetal heart rate
By following these steps, the nurse can provide the best possible care for the client and her baby.
Correct Answer is D
Explanation
Choice A rationale:
Fetal attitude in general flexion is not a contributing factor to difficult, prolonged labor. In fact, it is the normal fetal attitude
during labor. The fetus is typically in a position of general flexion, where the head is flexed forward, chin to chest, and the arms
and legs are flexed, with the arms crossed over the chest and the legs bent at the knees.
Choice B rationale:
Fetal lie being longitudinal is the normal and most common fetal lie during labor. In a longitudinal lie, the long axis of the fetus
is parallel with the long axis of the mother. This is the ideal and most common position for labor and delivery.
Choice C rationale:
A gynecoid pelvis is the most common type of female pelvis and is the most favorable for childbirth. It has a round shape with
a wide pubic arch, which allows for easier passage of the baby during delivery.
Choice D rationale:
A persistent occiput posterior (OP) position can indeed contribute to difficult, prolonged labor. In an OP position, the baby’s
occipital bone is towards the mother’s posterior side. This position can cause labor to be more painful and last longer because the baby’s head diameter that presents to the birth canal is larger. It can also cause back pain during labor, often referred to as "back labor"1.
