Which of the following best describes the role of an informatics nurse specialist?

Correct Answer: D

Rationale: The correct answer is D: Improving patient care through technology. Informatics nurse specialists focus on utilizing technology to enhance patient outcomes and streamline healthcare processes. They analyze data, implement new technologies, and design systems to improve efficiency and quality of care. This role involves understanding both nursing practice and technology to bridge the gap between the two, ultimately benefiting patients. A: Managing electronic health records - While informatics nurse specialists may oversee EHR systems, their primary focus is on using technology to enhance patient care, not just managing records. B: Providing technical support - While they may provide some technical support, their main role is to leverage technology to improve patient outcomes, not solely to troubleshoot technical issues. C: Educating nursing staff - While education is a part of their role, the primary objective of an informatics nurse specialist is to improve patient care through technology, not just educating staff.

Correct Answer: C

Rationale: The correct answer is C: medical-legal incident. When a client discharges AMA, it poses medical-legal risks for healthcare providers. This includes potential liability if the client experiences adverse outcomes post-discharge. Other choices are incorrect because discharging AMA is not solely focused on nurses (A) or physicians (B), but involves legal implications. It is also not purely patient-focused (D) as it impacts the healthcare team's legal responsibilities.

Correct Answer: C

Rationale: Rationale: - Patient outcomes are essential in a critical pathway for CHF to track progress and effectiveness of interventions. - Expected length of stay is not a core component but can be useful for resource planning. - Assigned healthcare team is important but not a core component in the critical pathway. - Medical history is relevant but not essential in the development of a critical pathway for CHF.

Correct Answer: C

Rationale: The correct answer is C: Time wasters. The manager missed the deadline due to distractions such as answering phone calls, checking emails, and engaging with staff, which are all considered time-wasting activities. These distractions prevented him from focusing on the task at hand, leading to missing the deadline. Goal setting (choice A) is about defining objectives, not the immediate cause of missing the deadline. Organization (choice B) refers to structuring tasks efficiently, which the manager failed to do. Assertiveness (choice D) relates to standing up for oneself and making decisions, not the primary reason for missing the deadline in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Unfreeze the system. According to Lewin's Change Theory, the first step in the change process is to unfreeze the current state or system to prepare for change. This involves creating awareness of the need for change, addressing any resistance, and establishing a sense of urgency. Moving the system to a new level (choice B) and refreezing the system (choice C) are subsequent steps in the change process after unfreezing. Evaluating the system (choice D) comes later in the process to assess the effectiveness of the change implemented. Therefore, unfreezing the system is the critical initial step to facilitate successful change implementation.
