The nurse observes variable decelerations on the fetal monitor tracing.
Which of the following is a correct interpretation of this finding?
Variable decelerations are related to the use of narcotic analgesics.
Variable decelerations are due to umbilical cord compression.
Variable decelerations are caused by maternal hypotension.
Variable decelerations are indicative of fetal hypoxia.
The Correct Answer is B
Choice A rationale
Variable decelerations are not related to the use of narcotic analgesics. Narcotic analgesics can cause other fetal heart rate changes, such as decreased variability, but they do not cause variable decelerations.
Choice B rationale
Variable decelerations are due to umbilical cord compression. This is the correct interpretation. Umbilical cord compression can lead to transient decreases in fetal blood flow and oxygenation, resulting in variable decelerations on the fetal monitor tracing.
Choice C rationale
Variable decelerations are not caused by maternal hypotension. Maternal hypotension can lead to late decelerations due to uteroplacental insufficiency, but it does not cause variable decelerations.
Choice D rationale
Variable decelerations are not indicative of fetal hypoxia. While severe and persistent variable decelerations can lead to fetal hypoxia, the primary cause of variable decelerations is umbilical cord compression.

Correct Answer is A
Explanation
Choice A rationale
This statement is incorrect because Stage 2 of labor does not involve the delivery of the placenta. Stage 2 starts with the complete dilation and effacement of the cervix and ends with the delivery of the fetus. The delivery of the placenta occurs in Stage 3 of labor.
Choice B rationale
This statement is correct. Stage 2 of labor begins with complete effacement and dilation of the cervix. This stage is characterized by the mother pushing and the eventual delivery of the baby.
Choice C rationale
This statement is also correct. Stage 2 starts when the cervix is fully dilated, allowing the mother to start pushing. This stage continues until the baby is born.
Choice D rationale
This statement is incorrect. Stage 2 ends with the delivery of the fetus, not the placenta. The delivery of the placenta is part of Stage 3 of labor.
Correct Answer is A
Explanation
Choice A rationale
The “Passenger” refers to the fetus and its position, size, and presentation. In this case, the fetus has an estimated weight of 9 lbs and is in the left occiput posterior (LOP) position. These factors can complicate labor by making it more difficult for the fetus to navigate through the birth canal, potentially leading to prolonged labor and increased risk of interventions.
Choice B rationale
The “Passage” refers to the birth canal, including the pelvis and soft tissues. While the passage is an important factor in labor, the primary concern in this scenario is the size and position of the fetus, which falls under the “Passenger” category.
Choice C rationale
The “Powers” refer to the strength and frequency of uterine contractions. Although the patient is having contractions every 3 minutes, the main concern here is the fetal size and position, which are more directly related to the "Passenger"4.
Choice D rationale
The “Psyche” refers to the psychological state of the mother, including her stress levels and emotional well-being. While important, the primary concern in this scenario is the physical factors related to the fetus, which are categorized under the "Passenger"4.
