ATI PN Maternity ( 62 Questions)
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 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.
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.
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.
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.
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.
