When describing a recent medical procedure, katrina says, "the worst part was the thought of that needle being stuck through my abdomen." given this description, katrina appears to have undergone a(n):

amniocentesis.

Explanation:

Amniocentesis is a medical procedure performed to obtain a sample of amniotic fluid (the fluid from the bag that bathes the fetus). The procedure is performed using an ultrasound device to guide a needle through the maternal abdomen into the amniotic cavity. When the needle reaches the amniotic cavity, about 20 ml of aspiration fluid is aspirated.
