Gastrointestinal Practice Questions Questions
Question 1 of 5
Which of the following statements about fat and fat digestion/absorption is true?
Correct Answer: D
Rationale: The correct answer is D because none of the statements are true. A is incorrect because fat-soluble vitamins are incorporated into chylomicrons before absorption. B is incorrect because triglycerides are resynthesized in the intestinal cell but packaged into chylomicrons, not directly exported. C is incorrect because pancreatic lipase functions best at a pH of around 7-8, not 3. So, the correct answer is D as all the other choices are incorrect.
Question 2 of 5
Which finding by the nurse during abdominal auscultation indicates a need for a focused abdominal assessment?
Correct Answer: C
Rationale: The correct answer is C, absent bowel sounds. Absence of bowel sounds may indicate a serious issue requiring further assessment. Normal bowel sounds include soft gurgles and clicks, so choices A, B, and D are variations of normal findings and do not necessarily indicate a need for further assessment. Absent bowel sounds could indicate bowel obstruction, peritonitis, or ischemia, warranting a focused abdominal assessment to determine the underlying cause.
Question 3 of 5
After several days of antibiotic therapy for pneumonia, an older hospitalized patient develops watery
Correct Answer: A
Rationale: The correct answer is A because the nurse should prioritize assessing the patient's condition to ensure immediate safety and appropriate intervention. This includes evaluating for signs of dehydration, electrolyte imbalance, and potential complications like Clostridium difficile infection. Option B is not the first action as immediate assessment is crucial. Option C is important but not the priority at this moment. Option D is important but should not be the first action in this scenario.
Question 4 of 5
The processes of chewing are referred to as _____.
Correct Answer: B
Rationale: The correct answer is B: mastication. Mastication refers to the mechanical process of chewing food in the mouth using the teeth and jaws. This process breaks down food into smaller pieces, making it easier to swallow and digest. Churning (A) is the mixing of food with digestive enzymes in the stomach. Peristalsis (C) is the involuntary muscle contractions that move food through the digestive tract. Deglutition (D) is the process of swallowing food. Mastication is the most appropriate term for the process of chewing specifically.
Question 5 of 5
Pancreatitis is mainly the result of _____ activity.
Correct Answer: D
Rationale: Pancreatitis is mainly the result of trypsin activity. Trypsin is an enzyme produced by the pancreas to aid in digestion. When trypsin becomes activated within the pancreas itself, it can lead to the digestion of pancreatic tissue and cause inflammation, leading to pancreatitis. Bile (A) and bacterial (B) activities are not primary causes of pancreatitis. Carboxypeptidase (C) is another pancreatic enzyme, but its activity does not play a significant role in causing pancreatitis compared to trypsin.
