Correct Answer: A

Rationale: The correct answer is A: Theories. Theories are comprehensive explanations that scholars use to understand commonly occurring events by organizing and explaining a set of principles or laws. Theories help in predicting and controlling events based on established frameworks. Constructs (B) refer to abstract concepts within theories, systems (C) are organized structures of elements, and propositions (D) are statements that describe relationships between concepts, but they do not provide the comprehensive explanations that theories do.

Correct Answer: A

Rationale: The correct answer is A because it specifies a measurable and achievable goal related to improving cardiac function through physical activities. It follows the SMART criteria (Specific, Measurable, Achievable, Relevant, Time-bound). Option B does not provide a specific outcome, while Option C focuses on pharmaceutical approaches rather than outcomes. Option D is unrelated to the goal of improving outcomes for heart failure patients. Thus, option A is the most appropriate choice for a well-defined and relevant outcome for the care of heart failure patients.

Correct Answer: A

Rationale: The correct answer is A: altruism. Altruism is the selfless concern for the wellbeing of others, which is demonstrated by the staff members helping the patient in need without hesitation. In this scenario, the staff members are putting the patient's needs above their own, showing compassion and empathy. This aligns with the principle of altruism in nursing, where caregivers prioritize the welfare of their patients. Choices B, C, and D are incorrect: B: Veracity refers to truthfulness and honesty. While these are important traits in nursing, they are not the focus of the staff members' actions in this scenario. C: Autonomy is the right of individuals to make decisions about their own care. In this situation, the patient is not exercising autonomy, but rather relying on the staff for assistance. D: Whistle-blowing involves reporting unethical or illegal behavior within an organization. There is no indication of any wrongdoing that would require whistle-blowing in this scenario.

Correct Answer: D

Rationale: The correct answer is D: scheduling daily activities. This is because positive time management skills involve planning and organizing tasks to effectively utilize time. By scheduling daily activities, individuals can prioritize tasks, set goals, and allocate time efficiently. This helps in achieving productivity and reducing stress. Choice A (maintaining an open-door policy) is incorrect as it pertains to communication style, not time management. Choice B (retaining all paperwork) is not directly related to time management but rather to organization. Choice C (returning all telephone calls immediately) is also not a direct indicator of effective time management as it focuses on communication responsiveness rather than overall time utilization.

Correct Answer: A

Rationale: Correct Answer: A - Negligence Rationale: 1. Negligence is the failure to provide the standard of care resulting in harm to the patient. 2. The nurse failed to report a significant change in the patient's condition, breaching the duty of care. 3. The increase in blood pressure could lead to serious complications, indicating the severity of negligence. Summary: B: Assault - Involves intentional threat or harm, not applicable in this scenario. C: Defamation of character - Involves false statements damaging reputation, not relevant in the context of patient care. D: Tort - A broader legal term encompassing various civil wrongs, but negligence is a specific type of tort applicable here.
