This is a first pregnancy for a 22-year-old woman. She is in her 16th week of pregnancy. She is scheduled for an amniocentesis and expresses concern that the "baby will be stuck with the needle." What should the nurse say to the woman?
What will be an ideal response
The nurse should explain that this is a fairly simple procedure and that an ultrasound will be used to visualize the position of the fetus and the amniotic sac to assist accuracy. The mother will need to decide whether to consent to the procedure after being informed of a small risk of losing the pregnancy (currently 0.3-1%) as a complication of amniocentesis.
