Correct Answer: C

Rationale: NPH insulin typically peaks 4-12 hours after administration, so a peak between 1530 and 2130 would be expected. Choice A (1130 and 1330) is too early for the peak effect of NPH insulin. Choice B (1330 and 1930) falls within the possible peak period but is not as accurate as choice C. Choice D (1730 and 2330) is too late for the peak effect of NPH insulin based on the typical peak timing.

Correct Answer: D

Rationale: In diabetic ketoacidosis (DKA), there is an excess of ketone bodies produced due to the breakdown of fatty acids for energy, leading to metabolic acidosis. An increased anion gap is a characteristic laboratory finding in DKA. The increased anion gap is a result of the accumulation of ketoacids and lactic acid in the blood, contributing to metabolic acidosis. Therefore, the correct answer is an increased anion gap. Choices A, B, and C are incorrect because in DKA, blood glucose levels are typically elevated, urine ketones are increased due to the breakdown of fatty acids, and serum bicarbonate is usually decreased as it is consumed in an attempt to buffer the acidosis.

Correct Answer: B

Rationale: Oral antidiabetic agents are specifically designed for type 2 diabetes mellitus. Type 1 diabetes requires insulin therapy as the primary treatment due to the absence of endogenous insulin production. Therefore, these medications are not effective for individuals with type 1 diabetes like the male client in this scenario. Choice A is incorrect as oral antidiabetic agents are not about preference but rather about treatment efficacy. Choice D is incorrect as being pregnant does not impact the effectiveness of oral antidiabetic agents; they are primarily indicated for type 2 diabetes.

Correct Answer: D

Rationale: The correct answer is D: Planning for the future. In this scenario, the nurse manager is engaging in decisional activities related to planning for the future. This involves analyzing potential impacts of policy changes and community shifts on the unit's functioning and making decisions based on predictions and foresight. Option A, resource allocation, focuses on distributing resources effectively. Option B, monitoring, involves observing and assessing current activities. Option C, job analysis and redesign, pertains to evaluating and restructuring roles and responsibilities within the unit, which is not the primary focus of the scenario provided.

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.
