Correct Answer: B

Rationale: In cases of food poisoning, a 2-year-old with reduced urine output is a critical finding indicating dehydration, requiring immediate attention to prevent complications. The reduced urine output is a sign of decreased fluid intake or increased fluid loss, putting the child at high risk for dehydration. This client should be seen first to assess hydration status, initiate necessary interventions, and prevent further complications. While the other symptoms presented by the other clients are concerning, the 2-year-old's decreased urine output poses the most immediate threat to their well-being.

Correct Answer: A

Rationale: A consultation with a Rapid Response Team (RRT) is most appropriate for the 45-year-old client described in Choice A. This client is 2 years post kidney transplant, presenting with no urine output for 6 hours, a temperature of 101.4°F, heart rate of 98 beats per minute, respirations of 20 breaths per minute, and a blood pressure of 88/72 mm Hg, along with restlessness. These clinical signs are indicative of possible acute renal failure and sepsis, requiring immediate intervention by the rapid response team. Choices B, C, and D do not present the same level of urgency and severity of symptoms as the client in Choice A, making them less appropriate for consultation with the RRT.

Correct Answer: D

Rationale: Assisting the client to sit in a chair is a crucial nursing intervention postoperatively. It helps prevent complications such as thrombosis, pneumonia, and pressure ulcers by promoting circulation and aiding in recovery. Changing the infusion rate of the intravenous fluid would require a physician's order and is not within the nurse's independent scope of practice. Encouraging the client to discuss feelings and administering medications for pain management are important interventions but may not be as immediately necessary as assisting the client in mobilizing early postoperatively.

Correct Answer: A

Rationale: The correct answer is A: Simple carbohydrates. Simple carbohydrates can cause rapid spikes in blood glucose levels, which can be problematic for patients with diabetes. These carbohydrates are quickly broken down and absorbed by the body, leading to sharp increases in blood sugar levels. In contrast, complex carbohydrates and fiber-rich carbohydrates are generally better choices for individuals with diabetes because they are digested more slowly, resulting in a more gradual rise in blood glucose levels. Choice B, complex carbohydrates, are a better option for diabetic patients compared to simple carbohydrates. Choice C, fiber-rich carbohydrates, can also be beneficial for individuals with diabetes as they help in regulating blood sugar levels. Choice D, all carbohydrates, is too broad of a statement as not all carbohydrates have the same impact on blood glucose levels.

Correct Answer: D

Rationale: Enteral feedings are commonly utilized for patients experiencing acute exacerbations of Crohn's disease to provide necessary nutrition and rest the bowel. Choices A, B, and C are incorrect because enteral feedings are not typically indicated for acute cholecystitis, hepatic encephalopathy, or ulcerative colitis in remission.
