Correct Answer: A

Rationale: The main goal of a nursing quality improvement (QI) program is to enhance patient safety. While reducing healthcare costs, ensuring regulatory compliance, and maintaining high patient satisfaction are important aspects of healthcare delivery, the primary focus of a QI program in nursing is to improve patient safety through practices such as error reduction, risk management, and enhancing the quality of care provided.

Correct Answer: D

Rationale: The correct answer is D: Contact precautions. Contact precautions are used when there is a risk of transmission of infections through direct or indirect contact. In this scenario, the client has an abdominal wound with purulent drainage, indicating a potential for infection transmission through contact. Droplet precautions (choice A) are used for infections transmitted through respiratory droplets, such as influenza. Protective environment (choice B) is used for immunocompromised clients. Airborne precautions (choice C) are used for infections transmitted through small droplets that remain in the air, like tuberculosis. Therefore, in this case, the nurse should initiate contact precautions to prevent the spread of infection.

Correct Answer: B

Rationale: The correct answer is B: 'To identify best practices and implement them.' Benchmarking in healthcare aims to compare performance metrics across organizations to identify the most effective practices and implement them. This helps healthcare providers improve their performance and outcomes by adopting proven successful strategies. Choices A, C, and D are incorrect because while benchmarking may involve comparing performance metrics and ensuring standards compliance, its primary purpose is to identify and implement best practices.

Correct Answer: D

Rationale: All the interventions listed are appropriate ways to minimize interruptions. By allowing voicemail to answer calls or turning off email notifications, the manager can focus solely on the assignment. Delegating tasks to staff nurses frees up the manager's time. Placing a 'Do Not Disturb for the Afternoon' sign on the office door sends a clear message to minimize interruptions and focus on the deadline. Therefore, all of the above interventions illustrate assertiveness to meet the deadline by minimizing interruptions.

Correct Answer: C

Rationale: Bioterrorism is considered an important emerging challenge to changes in health care due to its potential to disrupt healthcare systems, cause mass casualties, and create public health emergencies. Choices A, B, and D are not directly related to emerging challenges in health care. While nursing staff shortages are a significant issue, bioterrorism poses a different kind of threat that requires specific preparedness and response strategies.
