A nurse is teaching a client who is at 27 weeks of gestation and has pre-term labor about the signs and symptoms of true labor versus false labor.

Which of the following information should the nurse include in the teaching?

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.

“I will call my doctor if I have more than four contractions in an hour.” This statement indicates that the client understands the signs of preterm labor and when to seek medical attention.Preterm labor is defined as having regular contractions and cervical changes before 37 weeks of gestation.More than four contractions in an hour may indicate that preterm labor is occurring and requires prompt evaluation.

Choice A is wrong because drinking at least eight glasses of water every day is not a specific instruction for preventing preterm labor.However, dehydration can trigger contractions and should be avoided.

Choice B is wrong because lying on the back with a pillow under the knees can reduce blood flow to the uterus and the baby.This position can also increase the risk of blood clots in the legs.A better position is lying on the left side, which improves circulation and reduces pressure on the cervix.

Choice C is wrong because avoiding sexual intercourse until reaching term is not necessary for most women with a history of preterm labor.Sexual activity does not cause preterm labor or premature rupture of membranes (PROM).However, some women may be advised to abstain from sex if they have certain conditions, such as placenta previa or a short cervix.
