Review Timby's Introductory Medical-Surgical Nursing Thirteenth, North American Edition - Caring for Clients With Disorders of the Lower Gastrointestinal Tract related questions and content

Which test will best determine whether a client has an abnormality of the muscles surrounding the anal sphincter?

  • A. Kidneys, ureters, bladder (KUB)
  • B. Colonic transit studies
  • C. Defecography
  • D. Abdominal radiography
Correct Answer: C

Rationale: 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.
