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.

Choice A rationale:

Fetal head compression is unlikely to cause variable decelerations in the fetal heart rate. During contractions and labor, the fetal head may experience pressure, but this usually leads to early decelerations, not variable decelerations. Early decelerations are considered benign and are caused by the head's pressure stimulating the vagus nerve, resulting in a temporary decrease in heart rate.

Choice B rationale:

Umbilical cord compression is a known cause of variable decelerations in the fetal heart rate. When the umbilical cord is compressed, it can temporarily disrupt blood flow and oxygen supply to the fetus, leading to decelerations. Variable decelerations often appear as abrupt, sharp drops in the fetal heart rate and are typically characterized by their unpredictable

nature.

Choice C rationale:

Maternal opioid administration is not a direct cause of variable decelerations in the fetal heart rate. While opioids can cross the placenta and may affect the fetus, they are more likely to cause other issues, such as respiratory depression in the newborn, rather than variable decelerations.

Choice D rationale:

Uteroplacental insufficiency is not the primary factor causing variable decelerations. Uteroplacental insufficiency refers to an inadequate blood flow and oxygen delivery to the placenta, which c

Choice B rationale:

The correct answer is Choice B, which is "Newborn hypoglycemia.”. Newborn hypoglycemia is a potential complication associated with maternal gestational diabetes. When a pregnant woman has gestational diabetes, her blood glucose levels can be elevated, leading to increased insulin production in the fetus. After birth, the baby's insulin production continues at a high level, which can result in a rapid drop in blood glucose levels, causing hypoglycemia. This condition can be serious and requires close monitoring and timely intervention to prevent complications in the newborn.

Choice A rationale :

Placenta previa is not a complication associated with maternal gestational diabetes. Placenta previa occurs when the placenta partially or completely covers the cervix, which can lead to bleeding during pregnancy and delivery. However, this condition is not directly related to gestational diabetes, and there is no physiological rationale connecting the two.

Choice C rationale

Small for gestational age (SGA) newborn is not a direct complication of maternal gestational diabetes. SGA refers to babies who are smaller in size than expected for their gestational age. While poorly controlled diabetes during pregnancy can lead to large babies (macrosomia), it is not typically associated with small babies.

Choice D rationale

Oligohydramnios, which is a condition characterized by low levels of amniotic fluid, is not a common complication associated with maternal gestational diabetes. Oligohydramnios can be caused by various factors, but it is not specifically linked to gestational diabetes.
