Chapter 43 : Assessment of Digestive and Gastrointestinal Function Questions
Question 1 of 5
Probably the most widely used in-office or at-home occult blood test is the Hemoccult II. The patient has come to the clinic because he thinks there is blood in his stool. When you reviewed his medications, you noted he is on antihypertensive drugs and NSAIDs for early arthritic pain. You are sending the patient home with the supplies necessary to perform 2 hemoccult tests on his stool and mail the samples back to the clinic. What instruction would you give this patient?
Correct Answer: D
Rationale: Red meats, aspirin, nonsteroidal anti-inflammatory drugs, turnips, and horseradish should be avoided for 72 hours prior to the study, because they may cause a false-positive result. Also, ingestion of vitamin C from supplements or foods can cause a false-negative result. Acidic foods do not need to be avoided.
Question 2 of 5
A patient's sigmoidoscopy has been successfully completed and the patient is preparing to return home. Which of the following teaching points should the nurse include in the patient's discharge education?
Correct Answer: B
Rationale: Following sigmoidoscopy, patients can resume their regular activities and diet. There is no need to push fluids and neither fecal urgency nor rectal bleeding is expected.
Question 3 of 5
A nurse is caring for an 83-year-old patient who is being assessed for recurrent and intractable nausea. What age-related change to the GI system may be a contributor to the patient's health complaint?
Correct Answer: A
Rationale: Delayed gastric emptying occurs in older adults and may contribute to nausea. Changes to the small intestine and decreased saliva production would be less likely to contribute to nausea. Loss of esophageal sphincter function is pathologic and is not considered an age-related change.
Question 4 of 5
A patient has been experiencing significant psychosocial stress in recent weeks. The nurse is aware of the hormonal effects of stress, including norepinephrine release. Release of this substance would have what effect on the patient's gastrointestinal function?
Correct Answer: A,B,D
Rationale: Norepinephrine generally decreases GI motility and secretions, but increases muscle tone of sphincters. Norepinephrine does not increase the release of enzymes.
Question 5 of 5
A patient with cystic fibrosis takes pancreatic enzyme replacements on a regular basis. The patient's intake of trypsin facilitates what aspect of GI function?
Correct Answer: D
Rationale: Trypsin facilitates the digestion of proteins. It does not influence vitamin D synthesis, the digestion of fats, or peristalsis.
