Correct Answer: D

Rationale: The correct answer is D: Evaluation. In this scenario, the nurse researcher is determining the significance of findings, which falls under the evaluation phase of scientific inquiry. Evaluation involves assessing the results and determining their importance and relevance. It is crucial in determining the validity and impact of the research findings. A: Hypothesis - While formulating a hypothesis is an important step in the scientific method, it is not directly related to determining the significance of findings. B: Method - Refers to the procedures used to conduct the research study, not specifically related to evaluating the significance of findings. C: Data collection - Involves the process of gathering data, not directly related to determining the level of significance of findings.

Correct Answer: C

Rationale: The correct answer is C because institutional review boards (IRBs) are responsible for ensuring that research studies involving human subjects do not cause harm. IRBs evaluate the potential risks and benefits of the study to protect participants' rights and well-being. Choice A is incorrect because publication is not within the primary scope of IRBs. Choice B is incorrect as adding to nursing knowledge is not the main focus of IRBs. Choice D is also incorrect as funding approval is typically handled by separate entities and is not the primary role of IRBs.

Correct Answer: D

Rationale: The correct answer is D. Teaching a patient how to instill eye drops for glaucoma is a task that can be appropriately delegated to an LPN/LVN when the patient is stable and competence has been established. Here's the rationale: 1. Teaching is within the scope of practice for LPN/LVNs as it involves providing education and instructions to patients. 2. Administering medications IV (option B) requires a higher level of assessment and monitoring skills, making it inappropriate for delegation to an LPN/LVN. 3. Developing a plan of care (option C) involves critical thinking and decision-making skills beyond the scope of an LPN/LVN. 4. Administering an enema (option A) may involve assessing the patient's condition and response, which is beyond the typical scope of an LPN/LVN.

Correct Answer: D

Rationale: The correct answer is D: Improper construction that caused the leak and towel placement. This is a special cause variation because it is an external factor outside the patient's control that directly contributed to the incident. The construction causing water leaks and the placement of a towel to collect water created a hazardous environment leading to the fall. The other choices, A, B, and C, are common cause variations as they are related to the patient's behavior or medical condition which could have been managed or controlled within the usual process.

Correct Answer: B

Rationale: The correct answer is B because communities are indeed the first responders in any disaster. Local resources are typically the first to mobilize and provide immediate assistance due to their proximity to the affected area. Federal agencies may take time to arrive on the scene, so it is crucial for communities to have their own disaster response plans in place. Choice A is incorrect because the federal government can become involved in disasters even without known terrorist activities, especially in large-scale disasters. Choice C is incorrect as it oversimplifies the roles of different agencies in disaster response. Choice D is incorrect because state and federal agencies may still provide assistance even if local health care facilities are operational.
