A nurse is preparing to perform an amniocentesis on a client who is at 27 weeks of gestation and has pre-term labor.

Which of the following actions should the nurse take before the procedure?

“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.

Assess fetal heart rate and activity.

The nurse should identify that a client who reports a sudden gush of fluid from her vagina is at risk forpremature rupture of membranes (PROM), which can lead toinfection,cord prolapse, andfetal distress.Therefore, the priority action is to assess the fetal heart rate and activity to monitor for signs of hypoxia or distress.

Choice B is wrong because performing a nitrazine test on the fluid is not the first action.A nitrazine test can confirm the presence of amniotic fluid by detecting its alkaline pH, but it is not as urgent as assessing the fetal well-being.

Choice C is wrong because administering oxytocin (Pitocin) IV infusion is contraindicated in this situation.Oxytocin is used to induce or augment labor, but it can causeuterine hyperstimulation,fetal distress, andplacental abruptionif given to a client who has PROM.

Choice D is wrong because placing the client in Trendelenburg position is not recommended for a client who has PROM.Trendelenburg position can increase the risk ofcord prolapseandaspirationin this situation.
