A nurse is evaluating the fetal heart rate tracing of a client who is in pre-term labor and receiving magnesium sulfate.

The nurse should identify that which of the following patterns indicates a potential adverse effect of the medication on the fetus?

A. Referral to community services for support.

Referral to community services for support is an important part of the discharge plan for a client in preterm labor.Community services can provide education, counseling, home visits, and other resources to help the client cope with preterm labor and prevent complications.

B. Encouragement to smoke in moderation.Statement is wrong because smoking is harmful for the unborn baby and can increase the risk of preterm labor.Smoking should be avoided completely during pregnancy and the client should be advised to quit or seek help to quit.

C. Instructions for heavy lifting and strenuous exercise.Statement is wrong because heavy lifting and strenuous exercise can trigger contractions and worsen preterm labor.The client should be instructed to rest as much as possible and avoid activities that may cause uterine irritation or bleeding.

D. Recommendation to avoid kangaroo care.Statement is wrong because kangaroo care, or skin-to-skin contact with the baby, is beneficial for both the mother and the baby after birth.Kangaroo care can help regulate the baby’s temperature, heart rate, breathing, and blood sugar levels, as well as promote bonding, breastfeeding, and infection prevention.The client should be encouraged to practice kangaroo care as soon as possible after delivery.

According to the search results, magnesium sulfate can have a negative effect on the fetal heart rate (FHR) by lowering the baseline, decreasing the variability, and reducing the reactivity or acceleration pattern.Absent variability means that there is no fluctuation in the FHR and it indicates fetal hypoxia or acidosis.

This is a potential adverse effect of magnesium sulfate on the fetus and requires immediate intervention.

Choice A.Accelerations is wrong because accelerations are transient increases in the FHR that indicate fetal well-being.They are not affected by magnesium sulfate.

Choice B.Early decelerations is wrong because early decelerations are decreases in the FHR that occur with uterine contractions and are caused by fetal head compression.They are benign and do not indicate fetal distress.They are not associated with magnesium sulfate.

Choice C.Variable decelerations is wrong because variable decelerations are abrupt decreases in the FHR that vary in shape, duration, and timing and are caused by umbilical cord compression.

They may or may not indicate fetal compromise.
