A nurse is assessing a client following an amniocentesis. Which of the following findings should the nurse recognize as complications? (Select all that apply.)

A. Polyhydramnios is not a complication of amniocentesis; it is a condition related to excess amniotic fluid. B. Preterm labor can be triggered by the procedure due to uterine irritation or infection. C. Urinary tract infection is unrelated to amniocentesis unless catheterization was performed, but it is not a direct complication. D. Amnionitis (intra-amniotic infection) is a serious complication resulting from infection introduced during the procedure. E. Leakage of amniotic fluid can occur if the amniotic sac is punctured improperly or does not seal properly after the procedure.
