Correct Answer: C

Rationale: The correct answer is C: nonmaleficence. Nonmaleficence is the ethical principle of doing no harm to others. In this scenario, the nurse is deliberately putting clients at risk by not adhering to universal precautions, which violates the principle of nonmaleficence. By intentionally endangering others, the nurse is directly going against the ethical duty to prevent harm. A: Veracity refers to truthfulness, not relevant in this scenario. B: Beneficence is the ethical principle of doing good for others, not applicable as the nurse's actions are harmful. D: Autonomy is the principle of respecting an individual's right to make their own decisions, not relevant as the nurse is not respecting the clients' autonomy by putting them at risk without their consent.

Correct Answer: B

Rationale: The correct answer is B: model. In this scenario, the nurse used visual representation to illustrate the relationships among concepts in Peplau's theory. A model is a simplified representation of a real-world system that helps understand complex relationships. By listing concepts and drawing lines to denote relationships, the nurse created a visual model to clarify the interconnections between elements. A hypothesis (A) is a testable prediction, not a visual representation. A construct (C) is an abstract concept, not a visual representation of relationships. A variable (D) is a measurable factor that can change, not a visual representation of relationships.

Correct Answer: A

Rationale: The correct answer is A: Safe and effective care environment. The rationale is that assigning different nurses to care for a patient with shingles and a patient with HIV/AIDS is an example of maintaining infection control and preventing the spread of communicable diseases. This falls under the category of safe and effective care environment because it ensures proper isolation precautions are followed to protect both patients and healthcare workers. Summary: - Option A is correct because it relates to infection control and maintaining a safe care environment. - Option B, health promotion and maintenance, is not relevant to the scenario described. - Option C, psychosocial integrity, does not address the primary concern of preventing the spread of infection. - Option D, teaching/learning, is not the focus of the scenario, which is more about infection control and safety.

Correct Answer: A

Rationale: The correct answer is A because starting the workday productively sets a positive tone, leading to better focus and efficiency. By utilizing the first hour effectively, one can tackle important tasks when energy and concentration levels are at their peak. This approach helps in prioritizing and accomplishing key objectives early on, maximizing productivity throughout the day. Choice B is incorrect because completing trivial tasks first can waste valuable time and energy that could be better spent on more significant tasks. Choice C is incorrect as recreational activities can provide necessary mental breaks, leading to increased productivity and overall well-being. Choice D is incorrect because breaks are essential for maintaining focus and preventing burnout, ultimately enhancing productivity in the long run.

Correct Answer: B

Rationale: The correct answer is B: sentinel event. A sentinel event is an unexpected occurrence involving death or serious physical or psychological harm to a patient. In this scenario, the accidental cutting of sutures leading to evisceration constitutes a serious harm to the patient, making it a sentinel event. This event requires immediate investigation, analysis, and implementation of preventive measures to ensure patient safety. A: Root cause refers to the underlying reason for a problem, not the event itself. C: Variation in performance is related to inconsistencies in processes, not a specific critical incident like evisceration. D: Causal factor is a contributing element to an event, but it does not capture the severity and significance of a sentinel event like evisceration.
