Question 1 of 5
The absorption of fructose by intestinal mucosa is
Correct Answer: C
Rationale: The correct answer is C: facilitated transport. Fructose is absorbed through facilitated diffusion using specific carrier proteins in the intestinal mucosa. This process does not require energy input and allows fructose to move down its concentration gradient. Unlike active transport (requiring energy) and co-transport mechanisms (involving multiple substances), fructose absorption occurs through facilitated transport by specific carrier proteins. Simple diffusion is not the main mechanism for fructose absorption due to its hydrophilic nature. Thus, facilitated transport best describes how fructose is absorbed by the intestinal mucosa.
Question 2 of 5
A nurse is caring for a client who has ulcerative colitis and is teaching the client about the common link with Crohn's disease. Which of the following information should the nurse include?
Correct Answer: A
Rationale: The correct answer is A: Both are inflammatory. Ulcerative colitis and Crohn's disease are both inflammatory bowel diseases. Ulcerative colitis primarily affects the colon and rectum, while Crohn's disease can affect any part of the digestive tract. This common inflammatory nature is the link between the two conditions. Choices B and C are incorrect because Crohn's disease can start in any part of the digestive tract, not specifically in the rectum, and fistula formation is more common in Crohn's disease than in ulcerative colitis. Choice D is incorrect as not all cases of ulcerative colitis and Crohn's disease require frequent surgery; surgery is usually considered for complications or severe cases.
Question 3 of 5
A nurse is caring for a client who reports having chronic constipation. Which of the following herbal supplements should the nurse recommend?
Correct Answer: D
Rationale: The correct answer is D: Flaxseed. Flaxseed is rich in fiber, which helps promote bowel regularity and relieve constipation. The insoluble fiber in flaxseed adds bulk to stool, making it easier to pass. Ginseng (A) is not typically used for constipation. Coenzyme Q-10 (B) is not known to alleviate constipation. Cranberry juice (C) is more commonly used for urinary tract health, not constipation. Flaxseed is the best choice due to its high fiber content and effectiveness in promoting regular bowel movements.
Question 4 of 5
A nurse is caring for a client who is receiving total parenteral nutrition (TPN). The nurse notices that the solution bag is almost empty and there is not another bag of TPN to administer. Which of the following IV solutions should the nurse administer until the next bag of TPN solution is available?
Correct Answer: A
Rationale: The correct answer is A: 10% dextrose in water (D10W). When a TPN bag is almost empty, abruptly stopping it can lead to hypoglycemia. Administering D10W provides a temporary source of glucose to prevent this. D10W is a hypertonic solution that delivers a high concentration of dextrose for energy. Option B (0.45% NaCl) is hypotonic and lacks the necessary glucose content. Option C (Lactated Ringer's solution) does not contain glucose, and option D (D5LR) contains lactate, which may not be suitable for all patients. Administering D10W is the most appropriate choice to prevent hypoglycemia until the next bag of TPN is available.
Question 5 of 5
Katrina is diagnosed with lactose intolerance. To avoid complications with lack of calcium in the diet, which food should be included in the diet?
Correct Answer: D
Rationale: The correct answer is D: Dark green, leafy vegetables. Dark green, leafy vegetables are a good source of calcium and can help Katrina meet her calcium needs without consuming milk and cheese products. Since Katrina is lactose intolerant, consuming milk and cheese products can lead to gastrointestinal issues due to the inability to digest lactose. Fruits and whole grains do not provide significant amounts of calcium compared to dark green, leafy vegetables. Therefore, including dark green, leafy vegetables in the diet is the best option to prevent complications from lack of calcium intake.
