Correct Answer: C

Rationale: The correct answer is 'C: Ambiguity.' The rationale behind this is that the provided list of characteristics that successful change agents demonstrate includes 'realistic thinking' as one of the traits, not 'ambiguity.' Therefore, 'A: Energy,' 'B: Confidence,' and 'D: Trustworthiness' are not among the characteristics mentioned in the extract.

Correct Answer: A

Rationale: The main concern with collective bargaining is that it can create tension among nurses. The bargaining process may lead to divisions between staff nurses and management, rather than uniting them. This tension can arise from differing priorities, goals, or interests between the two groups, potentially impacting the effectiveness of the bargaining process. Choices B, C, and D are incorrect because the primary focus of the concern is on the potential negative impact on nurse relationships, not on reforming healthcare, ensuring economic security, or uniting nurses.

Correct Answer: D

Rationale: The correct answer is D, 'All of the above.' Environmental factors encompass a wide range of influences on decision-making in nursing. Personal preferences can impact how a nurse chooses a course of action, ethical considerations guide decision-making based on moral principles, and the availability of resources determines the options that are feasible. Therefore, all of these factors play a significant role in influencing decision-making in nursing. Choices A, B, and C are incorrect because each of them individually represents a specific environmental factor, whereas the correct answer D acknowledges that all of these factors collectively contribute to influencing decision-making.

Correct Answer: C

Rationale: In this scenario, the nurse should advise the patient to monitor her blood glucose every 4 hours and notify the clinic if it continues to rise. This is important because the patient is experiencing symptoms of an illness (sore throat and runny nose) that can lead to fluctuations in blood glucose levels. By monitoring frequently, any significant rise in blood glucose can be detected early, enabling prompt intervention. Choice A is incorrect because abruptly stopping glargine (Lantus) insulin can lead to uncontrolled blood glucose levels. Choice B is incorrect as limiting calorie intake is not the appropriate immediate action for managing high blood glucose levels. Choice D is also incorrect as adjusting carbohydrate intake based on glycosylated hemoglobin levels is not the immediate action needed in this acute situation.

Correct Answer: C

Rationale: The primary goal of evidence-based practice (EBP) is to enhance clinical decision making by integrating the best available evidence with clinical expertise and patient values. While improving patient outcomes is a significant result of EBP, the ultimate aim is to ensure that healthcare decisions are based on the most current, relevant, and reliable evidence. While reducing healthcare costs and ensuring patient safety are important in healthcare, they are not the primary goals of evidence-based practice.
