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?

A. After an amniocentesis, especially in the third trimester (such as 33 weeks’ gestation), the nurse should closely monitor for uterine irritability and contractions. A major complication of amniocentesis is stimulation of preterm labor due to uterine irritation, leakage of amniotic fluid, or infection. Therefore, monitoring for contractions is essential because it may indicate the onset of preterm labor, which requires immediate intervention. B. Vomiting is not a typical complication associated with amniocentesis. While nausea could occur due to anxiety or vasovagal response during the procedure, persistent vomiting is not a key or expected post-procedure complication requiring priority monitoring in this context. C. Hypertension is not a direct complication of amniocentesis. However, pregnancy-related hypertensive disorders such as preeclampsia are separate conditions that may develop independently but are not caused by the procedure itself. D. Epigastric pain is more commonly associated with severe preeclampsia or HELLP syndrome rather than amniocentesis. While it is an important obstetric warning sign, it is not a specific complication of the procedure being described.
