Correct Answer: C

Rationale: The correct instruction for the nurse to include during postoperative teaching following a hip arthroplasty is to 'Place a pillow between your legs when turning.' Placing a pillow between the legs when turning is crucial as it helps prevent dislocation of the hip prosthesis. This position aids in maintaining proper alignment and stability, thereby reducing the risk of complications after hip arthroplasty surgery. Choices A, B, and D are incorrect because they do not directly address the specific action needed to protect the hip prosthesis and prevent complications.

Correct Answer: A

Rationale: Elevating the head of the bed to 30° is the correct action to take when a client is receiving continuous enteral feedings through a nasogastric tube. This position helps prevent aspiration of the enteral feedings into the lungs, reducing the risk of aspiration pneumonia. Additionally, elevating the head of the bed promotes proper digestion and absorption of the feedings by utilizing gravity to facilitate movement into the stomach and through the gastrointestinal tract. Flushing the tube with water every 2 hours (Choice B) is not necessary for continuous feedings and may disrupt the feeding schedule. Replacing the feeding bag and tubing every 72 hours (Choice C) is not the standard recommendation unless there are specific concerns or complications. Checking the client's gastric residual every 8 hours (Choice D) is important but not the immediate action needed to prevent aspiration during enteral feedings.

Correct Answer: C

Rationale: The correct answer is C because decreasing fluid intake is essential in managing fluid retention and symptoms of heart failure. Restricting fluids helps prevent excessive fluid buildup in the body, thus reducing the workload on the heart and alleviating symptoms like swelling and shortness of breath. Choices A, B, and D are incorrect. Increasing intake of foods high in sodium can exacerbate fluid retention and worsen heart failure symptoms. Increasing potassium-rich foods is beneficial for some heart conditions but not heart failure specifically. Decreasing fiber intake is not a standard recommendation for heart failure management.

Correct Answer: D

Rationale: When a client with major fecal incontinence reports irritation in the perianal area, the nurse's initial action should be to assess the client's perineum to gather more information. By checking the perineum, the nurse can identify the extent and nature of the irritation, allowing for appropriate interventions to be initiated. This assessment is crucial in developing a comprehensive care plan and addressing the client's immediate needs effectively. Applying the nursing process priority-setting framework helps in planning care and prioritizing nursing actions, making assessment the initial step in this scenario. Applying a fecal collection system (choice A) would be premature without assessing the perineal area first. Similarly, applying a barrier cream (choice B) or cleansing and drying the area (choice C) should follow the assessment to ensure appropriate interventions are chosen based on the assessment findings.

Correct Answer: B

Rationale: The correct answer is B because decreasing the intake of calcium-rich foods can help manage and prevent the formation of renal calculi. Excessive calcium intake can contribute to the formation of these stones, so reducing calcium-rich foods is a key dietary modification for individuals with renal calculi. Choice A is incorrect as increasing calcium-rich foods can exacerbate the condition. Choice C is incorrect because increasing sodium-rich foods can lead to more stone formation due to increased calcium excretion. Choice D is incorrect as potassium-rich foods do not directly contribute to the formation of renal calculi.
