Correct Answer: D

Rationale: Clients who have sustained traumatic burns are at a higher risk of developing hyperkalemia due to cell lysis. When cells are damaged in a traumatic burn, potassium can leak out from the intracellular space into the bloodstream, leading to elevated serum potassium levels. Colitis, Cushing's syndrome, and overuse of laxatives are not typically associated with the same degree of cell damage or potassium shifts seen in traumatic burns, making them less likely to result in such high potassium levels.

Correct Answer: A

Rationale: The correct answer is A. The nurse manager's role in improving patient satisfaction involves setting clear expectations for patient satisfaction, monitoring progress, and providing feedback to staff members to continuously improve patient care. Choice B is incorrect as gathering data and implementing strategies are typically part of quality improvement initiatives but do not solely define the nurse manager's role. Choice C is incorrect because the nurse manager is responsible for setting expectations and monitoring progress rather than developing the improvement plan. Choice D is incorrect as involving patients and families and gathering feedback are important aspects, but the question specifically asks about the nurse manager's role, which primarily involves setting expectations, monitoring progress, and providing feedback to staff.

Correct Answer: A

Rationale: When a client experiences secondary failure to an oral antidiabetic agent like glipizide, the next step is often to initiate insulin therapy. This is because secondary failure indicates that the current oral antidiabetic medication is no longer effective in managing blood glucose levels, and insulin therapy may be required to adequately control blood sugar. Switching to a different oral antidiabetic agent may not be effective if there is already resistance to the current agent. Adding another oral antidiabetic agent may not address the underlying issue of secondary failure. Restricting carbohydrate intake is important for diabetes management but is not the primary intervention indicated in this scenario of secondary failure to glipizide.

Correct Answer: C

Rationale: In an Addisonian crisis, there is a lack of adrenal hormones leading to severe hypotension. Hypertension (choice A) is not a typical sign of Addisonian crisis but can occur in conditions like pheochromocytoma. Hyperglycemia (choice B) is not a characteristic sign of an Addisonian crisis. Tachycardia (choice D) may occur as a compensatory mechanism in response to hypotension, but severe bradycardia is more common in an Addisonian crisis.

Correct Answer: C

Rationale: Insulin injection sites should be rotated every 2-3 weeks to prevent lipodystrophy and ensure proper insulin absorption. Option A ('Every third day') is too frequent and does not allow enough time for the previous site to heal properly. Option B ('Every week') might not provide adequate time for the tissue to recover. Option D ('Every 2-4 weeks') could potentially lead to overuse of a single injection site, increasing the risk of lipodystrophy and inconsistent insulin absorption. Therefore, the recommended interval of every 2-3 weeks is optimal for insulin injection site rotation.
