Correct Answer: A

Rationale: The nurse manager's role in managing conflict involves identifying the sources of conflict and working with staff members to resolve them in a constructive manner. This includes addressing conflicts at their root cause and guiding staff towards effective resolution. Choice B is incorrect as the nurse manager typically does not act as a mediator but rather empowers staff to resolve conflicts themselves. Choice C is incorrect as while facilitating communication is important, it is not the sole responsibility of the nurse manager. Choice D is incorrect as providing training and support for conflict management is part of the role, but the primary responsibility lies in addressing the sources of conflict directly.

Correct Answer: C

Rationale: The correct answer is C. Glycosylated hemoglobin (HbA1c) reflects average blood glucose levels over the past 3 months. This test is used to assess long-term blood sugar control in individuals with diabetes. Choice A is incorrect because fasting is not required for an HbA1c test. Choice B is judgmental and not supported by the information provided. Choice D is not the most accurate statement to make based on the HbA1c result; adjusting insulin would depend on a more comprehensive assessment of the client's overall diabetes management.

Correct Answer: A

Rationale: The correct instruction for the client is to take the regular insulin first, then the NPH insulin. Regular insulin should be administered before NPH insulin to prevent contamination and maintain the potency of each insulin type. Choice B is incorrect because NPH insulin should not be taken before regular insulin. Mixing the insulins in a separate syringe, as suggested in choice C, is not recommended as it may alter the effectiveness of the insulins. Choice D is also incorrect as taking the regular insulin first and immediately following it with NPH insulin is not the recommended administration sequence.

Correct Answer: A

Rationale: The correct instruction when taking metformin (Glucophage) is to take the medication with meals. Taking metformin with meals helps to reduce gastrointestinal side effects and improve absorption. Choice B is incorrect because taking metformin on an empty stomach can increase the risk of gastrointestinal side effects. Choice C is incorrect because missing a meal does not mean the medication should be avoided; the client should still take it with the next meal. Choice D is incorrect because there is no specific recommendation to take metformin before bedtime.

Correct Answer: A

Rationale: Meeting with a new nurse to discuss progress and areas for improvement is an effective communication method.
