Correct Answer: C

Rationale: When a patient taking metformin develops an allergic rash from an unknown cause and is prescribed prednisone, the nurse should anticipate that the patient may require administration of insulin while taking prednisone. Prednisone can increase blood glucose levels by antagonizing the effects of insulin, leading to hyperglycemia. Therefore, the patient may need additional insulin to manage blood sugar levels effectively. The other options are incorrect as prednisone would not directly cause a need for a higher-calorie diet, acute hypoglycemia, or rashes caused by a metformin-prednisone interaction.

Correct Answer: D

Rationale: An informatics nurse specialist focuses on improving patient care through technology by implementing, optimizing, and leveraging healthcare information systems. While managing electronic health records and providing technical support may be part of their responsibilities, the primary goal is to enhance patient outcomes and healthcare delivery through the strategic use of technology. Educating nursing staff, although important, is typically not the core role of an informatics nurse specialist.

Correct Answer: B

Rationale: Professional nurses who seek mentoring relationships work with their mentors to gain objective feedback, guidance, and confidence. A mentoring relationship is critical when making job decisions, establishing goals, discussing professional judgment, considering ethical issues, and in determining challenges for growth. Choice B, "Assuming each other's characteristics," is incorrect because mentoring is about learning, guidance, and support to develop one's own professional identity, not about assuming someone else's characteristics. Choices A, C, and D are all beneficial outcomes of mentoring relationships, including instilling a sense of accomplishment, fostering interdependence, and promoting self-esteem, respectively.

Correct Answer: A

Rationale: The correct answer is A: 'Unfreeze the system.' According to Lewin's Change Theory, unfreezing the system is the initial step in the change process. This step involves preparing the organization for change by creating awareness of the need for change, addressing any resistance, and establishing a sense of urgency. Choice B, 'Move the system to a new level,' is incorrect as it does not align with the first step of unfreezing. Choice C, 'Refreeze the system,' is incorrect as it pertains to the final stage of solidifying the change, not the first step. Choice D, 'Evaluate the system,' is incorrect as evaluation typically occurs after the change has been implemented, not at the beginning of the change process.

Correct Answer: B

Rationale: The major difference between quality management and benchmarking is that benchmarking compares outcomes in a variety of settings and disciplines. Choice A is incorrect because quality management can be applied in both inpatient and outpatient settings. Choice C is incorrect as quality management is not limited to primary care and can be implemented across various healthcare settings. Choice D is incorrect as benchmarking does not solely focus on nursing outcomes but rather compares outcomes across different disciplines and settings.
