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.

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: By using expert power in the workplace, nurses increase their professional influence. Expert power is derived from an individual's knowledge, skills, or expertise in a particular area. This allows nurses to influence others based on their competence and credibility, rather than through political skills (choice A), reward power (choice B), or the combination of power and politics (choice D). While political skills and understanding power dynamics can be beneficial, expert power is particularly effective in enhancing a nurse's professional influence.

Correct Answer: D

Rationale: The correct answer is D. Reviewing the information with the client and family should be addressed first. This step involves ensuring that the client and family fully understand the information provided, which is crucial before proceeding with any other responsibilities. Taking vital signs (choice A) is important but not the priority in this scenario. Answering the client's questions (choice B) and evaluating client teaching (choice C) can come after reviewing the information to ensure effective communication and understanding.

Correct Answer: D

Rationale: In a situation where a visitor arrives on the unit with a gun, it is essential to prioritize the safety of patients and staff. Immediately notifying security with all the relevant details is the correct course of action. Asking the visitor to leave or engaging them could escalate the situation and put everyone at risk. Similarly, requesting the gun from the visitor directly is not advisable as it could lead to a dangerous confrontation. By alerting security promptly, you enable trained professionals to handle the situation safely and effectively, minimizing risks and ensuring the safety of all individuals involved.
