Correct Answer: D

Rationale: The correct answer is D. Anxiety and exercise can significantly alter the character of respirations, increasing the rate and depth. Smoking primarily affects the health of the respiratory system in the long term but may not immediately impact the character of respirations. Therefore, choice C is incorrect. Choices A and B are correct as anxiety and exercise can lead to changes in the rate and depth of respirations.

Correct Answer: D

Rationale: Elevating the head of the bed to 30 degrees reduces the risk of aspiration by promoting proper digestion and preventing reflux. Warming the formula to room temperature is essential to prevent discomfort and complications. Aspirating and measuring the gastric aspirate is not a recommended nursing action for monitoring enteral feeding via a nasogastric tube, as it can introduce the risk of introducing contaminants into the feeding tube. Therefore, choices A and B are incorrect, making choice D the correct answer.

Correct Answer: B

Rationale: Performing active range of motion exercises is the priority intervention for a client on strict bed rest. These exercises help prevent complications such as thromboembolism and muscle atrophy by promoting circulation and maintaining muscle strength. Encouraging liquids, elevating the head of the bed, and providing a high-fiber diet are important interventions but not the priority when compared to preventing serious complications associated with immobility.

Correct Answer: B

Rationale: In the procurement process, the FIRST step is to establish requirements. This step involves identifying and defining the needs for supplies and equipment before moving forward with the procurement process. Keeping hand receipts up to date (Choice A) is a task related to tracking and managing inventory but comes after the requirements have been established. Requisitioning supplies and equipment (Choice C) and receiving, inspecting, and storing items (Choice D) are subsequent steps in the procurement process that follow after the requirements have been determined.

Correct Answer: C

Rationale: The correct answer is C: 'It is a circular process of continued nursing care.' The four-step method of assessment, planning, implementation, and evaluation in nursing is a continuous and cyclical process. Choice A is incorrect because the method is not solely problem-focused; it involves a comprehensive approach. Choice B is incorrect as it does not capture the cyclical nature of the process. Choice D is incorrect as the method is systematic and not based on trial-and-error but rather evidence-based practice.
