What complication should a nurse monitor for in a client who has just had an amniocentesis?

The appropriate complication to monitor for after an amniocentesis is the occurrence of contractions. During the procedure, a needle is inserted into the amniotic sac to collect fluid, which can stimulate uterine activity. It is essential for the nurse to observe for any signs of contractions as they can indicate irritation of the uterus or potential preterm labor. Monitoring for contractions, therefore, ensures that any adverse effects are identified and managed promptly, maintaining the safety and health of both the mother and the fetus.

Other possibilities, such as hemorrhage, fever, and preeclampsia, while important health considerations, are not directly related to the immediate aftermath of an amniocentesis as contractions are. Thus, the focus on contractions is key to the immediate post-procedure care.
