Gastrointestinal Assessment Questions Questions
Question 1 of 5
One of the major functions of bile salts is to
Correct Answer: B
Rationale: The correct answer is B because bile salts emulsify fat into smaller droplets, increasing the surface area for enzymes to break down fats into fatty acids and glycerol. This aids in fat digestion and absorption in the small intestine. Choice A is incorrect as bile salts do not directly break down fats into fatty acids and glycerol. Choice C is incorrect as bile salts do not break down fats into cholesterol and lecithin. Choice D is incorrect as bile salts do not emulsify fats to bilirubin, but rather help in the digestion of fats.
Question 2 of 5
Which statement about intestinal 'brakes' and 'accelerators' is FALSE?
Correct Answer: A
Rationale: The correct answer is A because dietary starch does not cause insulin release from the pancreas, but rather stimulates the release of incretin hormones like glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). These incretins help regulate blood sugar levels postprandially and do not directly affect intestinal motility. Incorrect choices: B: Food in the stomach causing gastrin release is true and stimulates acid secretion. C: Short-chain fatty acids moving from colon to caecum promoting ileo-caecal motility is true. D: The arrival of lipid in the duodenum causing a reduction in motility is true.
Question 3 of 5
The three pairs of extrinsic salivary glands are:
Correct Answer: D
Rationale: The correct answer is D because the extrinsic salivary glands are the parotid, submandibular, and sublingual glands. The parotid gland is located near the ear, the submandibular gland is under the mandible, and the sublingual gland is under the tongue. A is incorrect because the ethmoidal gland is not an extrinsic salivary gland. B is incorrect because the buccal gland is not an extrinsic salivary gland. C is incorrect because the buccal gland is not an extrinsic salivary gland; it is a minor salivary gland located in the cheek.
Question 4 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 5 of 5
A client with proctitis needs a rectal suppository. A senior nursing student assigned to this client tells you that she is afraid to insert the suppository because she has never done it before. What is the most appropriate action in supervising this student?
Correct Answer: D
Rationale: Correct Answer: D Rationale: 1. Supervising students is part of the nursing role. 2. As a tutor, your responsibility is to guide and teach students. 3. Showing the student how to insert the suppository will help build their skills and confidence. 4. Talking to the instructor ensures proper supervision and support for the student's learning. 5. Reporting or dismissing the student is not constructive and goes against the principles of education and mentorship.
