A nurse is assisting in the care of a client who is in active labour. The nurse notes variable decelerations of the FHR. The nurse should identify which of the following is a cause of variable decelerations.
Fetal head compression.
Umbilical cord compression.
Maternal fever.
Polyhydramnios.
The Correct Answer is B
Choice A rationale:
Choice A, fetal head compression, is not the correct answer in this case. Fetal head compression can cause early decelerations in the FHR, not variable decelerations. Early decelerations are often a result of the fetal head being compressed during contractions and are considered benign and expected during labor.
Choice B rationale:
The correct answer is choice B, which is umbilical cord compression. Variable decelerations of the fetal heart rate (FHR) can occur during labor due to various rationales, and umbilical cord compression is one of the common causes. When the umbilical cord gets compressed, it can briefly reduce or restrict the blood flow and oxygen supply to the fetus, leading to temporary decelerations in the FHR.
Choice C rationale:
Choice C, maternal fever, is also not the correct answer for variable decelerations in FHR. Maternal fever can be a sign of infection, and it may lead to other fetal heart rate abnormalities, such as tachycardia (an increased heart rate), but it is not specifically associated with variable decelerations.
Choice D rationale:
Choice D, polyhydramnios, is not the cause of variable decelerations in this scenario. Polyhydramnios refers to an excessive accumulation of amniotic fluid around the fetus. While it can have implications for pregnancy, it is not directly linked to variable decelerations of the FHR.

Correct Answer is B
Explanation
Choice A rationale:
Stimulate the infant to cry. While stimulating the infant to cry is a common practice to assess the newborn's respiratory function, it is not the first action the nurse should perform in this situation. The newborn may cry spontaneously or may require other interventions, such as clearing the respiratory tract, before crying.
Choice B rationale:
Clear the respiratory tract. Clearing the respiratory tract is the priority action in this scenario. It ensures that the airway is open and allows the infant to breathe effectively. This is crucial because newborns are at higher risk of respiratory distress after birth, and prompt action can prevent complications.
Choice C rationale:
Dry the infant off and cover the head. Drying the infant off and covering the head are important steps to prevent heat loss and maintain the newborn's body temperature. However, these actions can be delayed briefly until the respiratory tract is cleared, as the immediate focus should be on ensuring the infant's ability to breathe.
Choice D rationale:
Clamp the umbilical cord. Clamping the umbilical cord is a standard procedure after birth to prevent bleeding and infection. However, it is not the priority in this situation. The first step should be to ensure the newborn's airway is clear and they can breathe adequately.
Correct Answer is D
Explanation
The correct answer is choice D. Uterine contraction lasting 2 min.
Choice A rationale:
Early decelerations in the FHR are usually not a concern during the second stage of labor. They are a normal physiological response to the compression of the fetal head during contractions and are generally considered benign.
Choice B rationale:
Pelvic pressure with contractions is a normal finding during the second stage of labor as the baby descends into the pelvis. It does not typically require reporting to the provider unless it is associated with other concerning symptoms.
Choice C rationale:
A bloody show from the vagina is a common and expected finding during the second stage of labor. It indicates that the cervix is dilating and effacing, which is a normal part of the labor process.
Choice D rationale:
A uterine contraction lasting 2 minutes is abnormal and could indicate uterine tachysystole, which can lead to fetal distress due to reduced uterine blood flow and oxygen to the fetus. This finding should be reported to the provider immediately.
