Chapter 43 : Assessment of Digestive and Gastrointestinal Function Questions
Question 1 of 5
A patient has sought care because of recent dark-colored stools. As a result, a fecal occult blood test has been ordered. The nurse should instruct the patient to avoid which of the following prior to collecting a stool sample?
Correct Answer: A
Rationale: NSAIDs can cause a false-positive fecal occult blood test. Acetaminophen, vitamin D supplements, and fiber supplements do not have this effect.
Question 2 of 5
The nurse is preparing to perform a patient's abdominal assessment. What examination sequence should the nurse follow?
Correct Answer: A
Rationale: When performing a focused assessment of the patient's abdomen, auscultation should always precede percussion and palpation because they may alter bowel sounds. The traditional sequence for all other focused assessments is inspection, palpation, percussion, and auscultation.
Question 3 of 5
A patient who has been experiencing changes in his bowel function is scheduled for a barium enema. What instruction should the nurse provide for postprocedure recovery?
Correct Answer: C
Rationale: Adequate fluid intake is necessary to rid the GI tract of barium. The patient must not remain NPO after the test and enemas are not used to cleanse the bowel of barium. There is no need to avoid dairy products.
Question 4 of 5
A nurse is caring for a newly admitted patient with a suspected GI bleed. The nurse assesses the patient's stool after a bowel movement and notes it to be a tarry-black color. This finding is suggestive of bleeding from what location?
Correct Answer: B
Rationale: Blood shed in sufficient quantities in the upper GI tract will produce a tarry-black color (melena). Blood entering the lower portion of the GI tract or passing rapidly through it will appear bright or dark red. Lower rectal or anal bleeding is suspected if there is streaking of blood on the surface of the stool or if blood is noted on toilet tissue.
Question 5 of 5
A nursing student has auscultated a patient's abdomen and noted one or two bowel sounds in a 2-minute period of time. How would you tell the student to document the patient's bowel sounds?
Correct Answer: B
Rationale: Documenting bowel sounds is based on assessment findings. The terms normal (sounds heard about every 5 to 20 seconds), hypoactive (one or two sounds in 2 minutes), hyperactive (5 to 6 sounds heard in less than 30 seconds), or absent (no sounds in 3 to 5 minutes) are frequently used in documentation. Paralytic ileus is a medical diagnosis that may cause absent or hypoactive bowel sounds, but the nurse would not independently document this diagnosis.
