The nurse is preparing a patient for a test that involves inserting a thick barium paste into the rectum with radiographs taken as the client expels the barium. What test will the nurse prepare the patient for?
A) Kidneys, ureters, bladder (KUB)
B) Colonic transit studies
C) Defecography
D) Abdominal radiography
C
Feedback:
In defecography, a thick barium paste is inserted into the rectum. Radiographs are taken as the client expels the barium to determine whether there are any anatomic abnormalities or problems with the muscles surrounding the anal sphincter. A KUB will not determine this. Colonic transit studies are used to determine how long it takes for food to travel through the intestines. Abdominal radiography will show the structure but does not determine the muscle ability surrounding the anal sphincter.
