The use of research to guide nursing practice is called:

Correct Answer: A

Rationale: The correct answer is A: utilization. Research utilization refers to the application of research findings in nursing practice to improve patient outcomes. Utilization involves integrating research evidence into clinical decision-making. Dissemination (B) refers to sharing research findings. Generalizability (C) pertains to the extent to which research findings can be applied to different populations or settings. Analysis (D) involves examining data to draw conclusions, but it does not specifically relate to using research in practice like utilization does.

Correct Answer: A

Rationale: The correct answer is A because Florence Nightingale is widely recognized as the pioneer of modern nursing research. During the Crimean War, she collected and analyzed data on patient care outcomes, demonstrating the importance of evidence-based practice in nursing. This laid the foundation for the development of nursing research as a formal discipline. Choice B is incorrect as nursing research did not start between 1900 and 1940, but rather with Nightingale's work. Choice C is incorrect because the focus of nursing research was not solely on doctorally prepared nurses but on improving patient care in general. Choice D is incorrect as the naturalistic paradigm is just one approach to research and not the starting point for nursing research.

Correct Answer: A

Rationale: The correct answer is A. Generalizability refers to the conclusion that findings from a sample can be applied to the entire population. In this case, the purpose of the study is to determine if the positive outcomes of steroid therapy in two randomized placebo-controlled trials for Rocky Mountain Spotted Fever can be generalized to a broader population of patients with the same condition. Choice B is incorrect because generalizability is not about the type of steroids used but about the applicability of study findings. Choice C is incorrect as it refers to selection bias, not generalizability. Choice D is incorrect as generalizability is about the application of findings, not the universality of bacteria types.

Correct Answer: A

Rationale: The correct answer is A: case management. Case management involves coordinating care for patients to ensure they receive appropriate services and resources. DRGs determine reimbursement based on patient diagnoses, making accurate classification crucial. Nurses in case management play a key role in ensuring patients are placed in the correct DRG category for optimal care and reimbursement. Other choices are incorrect because: B: Quality assurance focuses on monitoring and improving the quality of care, not specifically tied to DRG classification. C: Utilization review involves assessing the appropriateness and necessity of healthcare services, not directly related to DRG classification. D: Cost-control pertains to managing healthcare costs, but does not address the specific role of nurses in DRG classification and patient care coordination.

Correct Answer: C

Rationale: The correct answer is C: Insurance company. In the triad of health care, the third-party payer refers to an entity outside of the patient and health care provider that pays for the health care services. Insurance companies typically serve as third-party payers by covering a portion or all of the costs associated with medical treatments. The other choices (A, B, D) are not considered third-party payers in this context. Choice A refers to the client/patient receiving the health care services, choice B refers to the health care provider delivering the services, and choice D refers to a government agency that sets reimbursement rules but does not directly pay for the services rendered.
