Correct Answer: C

Rationale: To prevent aspiration in clients receiving continuous enteral feedings, the nurse should elevate the head of the bed to 45 degrees. This position helps reduce the risk of regurgitation and aspiration. Flushing the tube with water every 4 hours (Choice A) is important for maintaining tube patency but does not directly prevent aspiration. Positioning the client on the left side during feedings (Choice B) is not specifically related to preventing aspiration in this context. Checking gastric residual every 2 hours (Choice D) is important to assess feeding tolerance but does not directly prevent aspiration.

Correct Answer: A

Rationale: Limiting fluid intake is essential in managing patients with chronic kidney disease to prevent fluid overload, which can worsen kidney function. Increasing potassium intake is not recommended as patients with kidney disease often need to limit potassium. Providing a high-protein diet may put extra strain on the kidneys, so it is not ideal. Administering IV antibiotics is not a standard treatment for chronic kidney disease.

Correct Answer: D

Rationale: During early pregnancy, nausea and vomiting are common. Instructing the client to eat dry carbohydrates like crackers before getting out of bed can help alleviate these symptoms. This recommendation helps prevent an empty stomach, which can worsen nausea. High-protein foods (Choice A) may be harder to digest and could exacerbate nausea. Lying down after meals (Choice B) may increase gastric reflux and worsen symptoms. Drinking water with meals (Choice C) may make the client feel fuller, potentially worsening nausea.

Correct Answer: C

Rationale: Corrected Rationale: Redness and warmth are classic signs of inflammation, which are commonly seen in clients with deep vein thrombosis (DVT). These findings indicate increased blood flow and temperature in the affected area. Pain in the right lower extremity (Choice A) is not expected in a client with DVT affecting the left lower extremity. Cold skin (Choice B) is not a typical finding in DVT; instead, warmth is more indicative of inflammation. Shiny skin (Choice D) is not a common characteristic of DVT; rather, the skin may appear red, swollen, and warm due to the inflammatory process.

Correct Answer: D

Rationale: The correct answer is D. Warfarin's effectiveness is reduced by high intake of vitamin K-rich foods, so increasing their intake would contradict the treatment plan. Choices A, B, and C are all appropriate statements for a client on warfarin therapy. Avoiding vitamin K-rich foods helps maintain the medication's effectiveness, avoiding aspirin reduces the risk of bleeding, and monitoring blood pressure is essential for overall health monitoring.
