Gastrointestinal Assessment Questions Questions
Question 1 of 5
At which relative exercise intensity would you expect to utilize the most intramuscular triglycerides?
Correct Answer: B
Rationale: The correct answer is B (65% VO2 max) because at this intensity, the body primarily uses a combination of fats and carbohydrates for energy production. Intramuscular triglycerides are a source of fat utilized during moderate-intensity exercise. At 25% VO2 max (choice A), the body predominantly uses carbohydrates, while at 85% VO2 max (choice C) and 150% VO2 max (choice D), the reliance shifts towards carbohydrates due to the higher intensity levels. Therefore, option B is the most suitable intensity for utilizing intramuscular triglycerides efficiently.
Question 2 of 5
Which of the following pretest evaluation measures should the nurse ensure before a client undergoes the gallbladder series test?
Correct Answer: C
Rationale: Step-by-step rationale for the correct answer (C): Determining whether the client is pregnant is crucial before a gallbladder series test because the test involves radiation exposure, which can be harmful to a developing fetus. It is essential to ensure the safety of both the client and the unborn child. Summary: - A: Determining the work environment of the client is not directly related to the safety or appropriateness of a gallbladder series test. - B: Determining whether the client has a family history of GI disorders is important for overall health assessment but not specifically necessary for the pretest evaluation of a gallbladder series test. - D: Determining whether the client is allergic to seafood or iodine is relevant for contrast materials used in some imaging tests but not specifically for a gallbladder series test.
Question 3 of 5
A client is admitted to the hospital for a hemorrhoidectomy. Postoperatively, which of the following would a client's nurse be most concerned about?
Correct Answer: D
Rationale: The correct answer is D because excessive bloody drainage on the external gauze dressing could indicate hemorrhage, a serious complication post-hemorrhoidectomy. This requires immediate medical attention to prevent further complications. A: Pain at the incision site is expected postoperatively and can be managed with pain medication. B: A white blood count of 6.5 is within the normal range and not a cause for concern. C: Client's refusal of a stool softener is important for bowel movement management but is not the most immediate concern compared to excessive bloody drainage.
Question 4 of 5
A patient receives atropine, an anticholinergic drug, in preparation for surgery. The nurse expects this drug to affect the GI tract by doing what?
Correct Answer: C
Rationale: The correct answer is C: Decreasing secretions and peristaltic action. Atropine, as an anticholinergic drug, inhibits the action of acetylcholine, leading to decreased secretions and peristaltic movement in the GI tract. This results in reduced motility and secretion production. A: Increasing gastric emptying - This is incorrect because atropine actually slows down gastric emptying by reducing peristaltic action. B: Relaxing pyloric and ileocecal sphincters - This is incorrect because atropine does not directly relax these sphincters. D: Stimulating the nervous system of the GI tract - This is incorrect because atropine inhibits the parasympathetic nervous system, leading to decreased GI tract activity.
Question 5 of 5
The nurse monitors the laboratory results of the patient with protein-calorie malnutrition during treatment. Which result is an indication of improvement in the patient's condition?
Correct Answer: B
Rationale: The correct answer is B because an increase in serum transferrin levels indicates improvement in protein-calorie malnutrition as transferrin is a protein that binds and transports iron, which is essential for various body functions. When protein intake increases, transferrin levels also increase to support iron transport. A: Decreased lymphocytes do not directly reflect improvement in protein-calorie malnutrition. C: Increased serum potassium is not specific to improvement in protein-calorie malnutrition. D: Decreased serum prealbumin levels indicate ongoing malnutrition, not improvement.
