The nurse notes a nonreassuring pattern of the fetal heart rate. The mother is already lying on her left side. What nursing action is indicated?

Choice A reason:

Uteroplacental insufficiency is a condition where the placenta cannot deliver enough oxygen and nutrients to the fetus. This can cause fetal hypoxia and distress, which can be detected by late decelerations on the fetal heart rate monitor. Late decelerations are defined as a decrease in the fetal heart rate that begins after the peak of the contraction and returns to baseline after the contraction ends. This indicates that the fetus is not tolerating the reduced blood flow during the contractions and needs immediate intervention. • Choice B reason:

Umbilical cord compression is a condition where the umbilical cord is squeezed or twisted, reducing the blood flow and oxygen to the fetus. This can cause variable decelerations on the fetal heart rate monitor. Variable decelerations are defined as a decrease in the fetal heart rate that varies in timing, shape, and duration, and may or may not be associated with contractions. This indicates that the fetus is experiencing intermittent or sustained cord compression and may need repositioning or other interventions. • Choice C reason:

Maternal bradycardia is a condition where the mother's heart rate is slower than normal, usually less than 60 beats per minute. This can cause reduced blood flow and oxygen to the placenta and the fetus, but it does not cause late decelerations on the fetal heart rate monitor. Maternal bradycardia can be caused by various factors, such as medications, hypothermia, hypothyroidism, or vagal stimulation. It may need treatment depending on the cause and severity. • Choice D reason:

Fetal head compression is a condition where the fetal head is pressed against the cervix or the pelvic floor during labor, stimulating the vagus nerve and slowing down the fetal heart rate. This can cause early decelerations on the fetal heart rate monitor. Early decelerations are defined as a decrease in the fetal heart rate that begins with the onset of the contraction and returns to baseline with the end of the contraction. This indicates that the fetus is descending in the birth canal and is usually a normal and benign finding.

Choice A: Change her position to the right side

Changing the mother’s position to the right side can sometimes help improve fetal oxygenation by relieving pressure on the vena cava. However, since the mother is already lying on her left side, which is typically the preferred position to optimize blood flow, changing to the right side may not be as effective .

Choice B: Place a wedge under the left hip

Placing a wedge under the left hip is a common intervention to improve uteroplacental blood flow. This position helps to tilt the uterus off the vena cava, enhancing venous return and improving cardiac output, which can positively affect fetal oxygenation. This is why it is the correct answer.

Choice C: Lower the head of the bed

Lowering the head of the bed can help increase blood flow to the upper body and brain, but it does not specifically address the issue of improving uteroplacental blood flow. This action is less targeted for resolving nonreassuring fetal heart rate patterns.

Choice D: Place the mother in a Trendelenburg position

The Trendelenburg position, where the mother is laid flat on her back with her feet elevated higher than her head, is generally used to treat hypotension or to improve venous return in cases of shock. However, it is not typically recommended for nonreassuring fetal heart rate patterns as it can increase pressure on the diaphragm and reduce respiratory efficiency.
