Correct Answer: B

Rationale: The correct answer is B: Informatics. Nurses on the orthopedic unit are demonstrating informatics competency by using PDAs for medication review and accessing video clips for procedures. This showcases their ability to utilize technology to enhance patient care. Patient-centered care (A) focuses on individualized care, teamwork (C) emphasizes collaboration, and quality improvement (D) pertains to enhancing processes. The use of technology in this scenario aligns most closely with the informatics competency, making it the best choice.

Correct Answer: B

Rationale: The correct answer is B: Zero-based. Zero-based budgeting requires starting from scratch each budget cycle, meaning all expenses must be justified regardless of previous budgets. In this scenario, the nurse managers are planning for a budget based on the expectation of lower patient census due to the economic slowdown. This aligns with the zero-based approach as they will need to re-evaluate and justify all expenses to accommodate the changes in patient volume. A: Incremental budgeting involves making adjustments to the previous budget, which is not suitable for significant changes like a decrease in patient census. C: Productivity metrics focus on measuring efficiency and performance, rather than the budgeting approach. D: Capital budgeting is related to long-term investments in assets, which is not the primary focus in this scenario.

Correct Answer: C

Rationale: Correct Answer: C - Change agent Rationale: 1. A change agent is someone who identifies issues or concerns and takes action to implement positive changes. 2. In this scenario, the novice nurse recognized a potential problem with medication administration and spoke to the nurse manager to address it. 3. By seeking to improve medication safety practices, the novice nurse is actively working towards positive change within the healthcare setting. 4. The other choices are incorrect: - A "loner" implies someone who prefers to work alone, which is not relevant to the situation. - "Rutter" and "native" are not recognized terms in this context and do not apply to the nurse's actions.

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: B

Rationale: The correct answer is B: Hot-spot item, analysis level. In this scenario, the patient's symptoms suggest pericardial effusion or cardiac tamponade. To facilitate auscultation, the nurse should place the stethoscope at the point of maximal intensity of the heart sounds, which is typically at the apex of the heart or the lower left sternal border. This requires the nurse to analyze the patient's symptoms and apply knowledge of cardiac anatomy to determine the optimal auscultation site. A: Multiple-response item, comprehension level - This choice involves selecting multiple correct answers from a list of options based on understanding the presented information. It doesn't require the critical thinking and analysis needed in this scenario. C: Chart/exhibit item, application level - This choice involves interpreting information presented in a chart or exhibit to apply it to a specific situation. While it involves application, it doesn't require the same level of analysis as determining the best auscultation site. D: Drag-and
