Chapter 43 : Assessment of Digestive and Gastrointestinal Function Questions
Question 1 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 2 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.
Question 3 of 5
The nurse is caring for a patient who has a diagnosis of AIDS. Inspection of the patient's mouth reveals the new presence of white lesions on the patient's oral mucosa. What is the nurse's most appropriate response?
Correct Answer: D
Rationale: The nurse should inform the primary care provider of this abnormal finding in the patient's oral cavity, since it necessitates medical treatment. It would be inappropriate to try to remove skin lesions from a patient's mouth and salt water will not resolve this problem, which is likely due to candidiasis. A dietitian referral is unnecessary.
Question 4 of 5
A patient has been scheduled for a urea breath test in one month's time. What nursing diagnosis most likely prompted this diagnostic test?
Correct Answer: B
Rationale: Urea breath tests detect the presence of Helicobacter pylori, the bacteria that can live in the mucosal lining of the stomach and cause peptic ulcer disease. This test does not address fluid volume, nutritional status, or dentition.
Question 5 of 5
A female patient has presented to the emergency department with right upper quadrant pain; the physician has ordered abdominal ultrasound to rule out cholecystitis (gallbladder infection). The patient expresses concern to the nurse about the safety of this diagnostic procedure. How should the nurse best respond?
Correct Answer: B
Rationale: An ultrasound produces no ill effects and there are not specific limits on its use, even during pregnancy.
