A nurse is caring for a client who is at 33 weeks of gestation following an amniocentesis. The nurse should monitor the client for which of the following complications?

After amniocentesis, the most significant complication to monitor for is uterine contractions, which may indicate preterm labor triggered by the procedure's irritation of the uterus. Other complications include fluid leakage, bleeding, and fetal heart rate changes. Hypertension is associated with preeclampsia, not amniocentesis. Vomiting is not a known post-amniocentesis complication. Epigastric pain is associated with HELLP syndrome or preeclampsia, not amniocentesis.
