The nurse is planning care for a patient who has experienced moderate diarrhea for 3 days. Which collaborative intervention is most important to include in the plan of care?

Correct Answer: B

Rationale: The correct answer is B: Limit the patient's diet to clear liquids. This intervention is important to prevent further irritation to the gastrointestinal tract and help rehydrate the patient. Clear liquids are easier to digest and can help reduce diarrhea. A: Placing the patient on NPO status is not necessary unless there are signs of severe dehydration or complications. C: Administering parenteral nutrition is not indicated for moderate diarrhea and is a more invasive intervention. D: Restricting the patient's diet to soft foods only may not be as effective in managing diarrhea compared to clear liquids.

Correct Answer: A

Rationale: The correct answer is A: Administering antipyretics as prescribed. Elevated pulse can indicate fever, which may be a sign of infection. Administering antipyretics helps reduce fever, which can help lower the pulse rate. This intervention addresses the underlying cause of the elevated pulse. Increasing fluid intake (B) is important but does not directly address the elevated pulse. Encouraging rest (C) is beneficial but may not directly impact the pulse rate. Monitoring respiratory rate (D) is important but addressing the fever with antipyretics is the priority in this case.

Correct Answer: B

Rationale: The correct answer is B: haustra. The large intestine has haustra, which are pouches formed by muscle contractions that help in moving feces along the colon. Villi (choice A) and microvilli (choice C) are features of the small intestine, aiding in nutrient absorption. Lacteals (choice D) are lymphatic vessels in the small intestine. Therefore, the presence of haustra is a distinct feature of the large intestine, making it the correct choice in this context.

Correct Answer: B

Rationale: The correct answer is B. The small intestine is where the majority of digestion and absorption occur due to its large surface area for nutrient absorption. This is facilitated by villi and microvilli. Choice A is incorrect as the small intestine is lined with villi and microvilli, not smooth muscle. Choice C is incorrect because bile is produced in the liver and stored in the gallbladder. Choice D is incorrect as carbohydrate digestion primarily occurs in the mouth and small intestine.

Correct Answer: B

Rationale: The correct answer is B: amylase. Amylase is responsible for breaking down carbohydrates into smaller sugar molecules in the digestive system. It is produced in the saliva and pancreas. Lipase (A) digests fats, pepsin (C) digests proteins, and trypsin (D) also digests proteins, not carbohydrates. Therefore, amylase is the correct enzyme for carbohydrate digestion.
