Correct Answer: B

Rationale: The correct answer is 'Unfreezing the system.' In Lewin's Force-Field Model, unfreezing is the stage where the existing equilibrium is disrupted to motivate participants and prepare them for change. Building trust and recognizing the need for change are essential components of this stage. Choice A, 'Moving the system to a new level,' does not specifically address the initial stage of disruption. Choice C, 'Refreezing the system,' comes after change has been implemented, not before. Choice D, 'Institutionalization,' refers to the stage where the change becomes the new norm, which is different from unfreezing.

Correct Answer: B

Rationale: Surveys are one of the most effective tools to determine reasons for turnover because they allow employees to provide feedback anonymously, leading to more truthful responses. While questioning can be part of the process, surveys provide a structured and standardized way to collect data. Employee forums may not always elicit honest responses due to peer pressure or fear of repercussions. Telephone calls may not reach all employees and do not guarantee anonymity, potentially leading to biased or incomplete information.

Correct Answer: C

Rationale: The correct answer is C: Suppression. In this scenario, the nurse manager has implemented a suppression tactic by asking the staff nurse to transfer to another unit, which eliminates one of the conflicting parties from the current unit. This technique aims to resolve the conflict by physically separating the individuals involved. Choices A, B, and D are incorrect: Avoidance involves ignoring the conflict, withdrawal is the act of pulling out or retreating, and competition refers to a situation where one party's gain is at the expense of the other.

Correct Answer: C

Rationale: The correct answer is C. Liability policies can cover charges of libel, slander, assault, and HIPAA violations, in addition to malpractice claims. Choice A is incorrect as there are expenses involved in frivolous lawsuits. Choice B is incorrect because institutions can sue nurses found guilty of malpractice. Choice D is incorrect as nurses, not just doctors, can be sued for malpractice.

Correct Answer: A

Rationale: In a client experiencing vomiting and diarrhea, the nurse should expect findings such as dehydration, which can lead to hypovolemia and subsequent increased heart rate and decreased blood pressure. A blood pressure of 144/82 mm Hg is indicative of possible dehydration in this client. Urine specific gravity is typically increased in dehydrated individuals, so choices B and D are incorrect. Neck vein distention is not a typical finding associated with vomiting and diarrhea; therefore, choice C is also incorrect.
