Rationale: In this scenario, the client with type 1 DM has a high glucose level at bedtime. The appropriate action for the nurse is to administer the sliding scale insulin as ordered. This insulin regimen is specifically designed to manage high blood glucose levels. Calling the physician is not necessary as the protocol for sliding scale insulin is already in place. Encouraging fluid intake or providing orange juice is not the correct intervention for addressing high blood glucose levels in this case.

Correct Answer: C

Rationale: The correct answer is C: Kidney dialysis. A blood potassium level of 9.2 mEq/L indicates severe hyperkalemia, which can be life-threatening. Kidney dialysis is the most appropriate intervention to rapidly lower potassium levels in this situation. Choice A, intravenous potassium supplementation, would worsen the hyperkalemia. Choice B, intravenous calcium supplementation, is not the primary intervention for hyperkalemia. Choice D, parenteral nutrition, is unrelated to treating hyperkalemia and would not address the immediate concern.

Correct Answer: B

Rationale: The correct answer is to identify the medication name and dosage administered to the client in the incident report. This information is crucial for accurate documentation and investigation of the medication error. Choice A is incorrect because incident reports are usually kept confidential and not for personal keeping. Choice C is incorrect as obtaining an order from the client's provider is not necessary to complete an incident report. Choice D, while important, is not the only essential information needed for the incident report.

Correct Answer: B

Rationale: The major concern about the health-care system in the United States is the quality of care provided. While disease prevention and collaborative care are important aspects, the primary focus of concern is ensuring that the care delivered meets high standards in terms of effectiveness, safety, and patient outcomes. Reduction in hospital-acquired drug-resistant infections, although relevant, is not the primary concern when evaluating the overall quality of healthcare services.
