Correct Answer: D

Rationale: The correct answer is D, as exercise and a weight reduction diet are essential components in managing type 2 diabetes. Exercise helps lower blood glucose levels and improves insulin sensitivity. Weight reduction reduces insulin resistance. Choice A is incorrect because maintaining blood glucose levels between 180-200mg/dl is too high and can lead to complications. Choice B is incorrect as complete smoking cessation is crucial for overall health and diabetes management. Choice C is incorrect because eye examinations should be done annually, not every 2 years, to monitor for diabetic retinopathy. In summary, choice D is the best option as it directly addresses the management of type 2 diabetes.

Correct Answer: C

Rationale: The correct answer is C: “Nurses use evaluation to determine the effectiveness of nursing care.” Evaluation in nursing is essential to assess the outcomes of nursing interventions and determine the effectiveness of the care provided. It helps in identifying areas for improvement, making informed decisions, and ensuring quality patient care. Choice A is incorrect because evaluation is not solely about checking completion of tasks but rather assessing the impact of those interventions on patient outcomes. Choice B is incorrect as evaluation is not related to staffing decisions but focuses on assessing the quality of care delivery. Choice D is incorrect as evaluation is not about eliminating paperwork but rather about improving care outcomes.

Correct Answer: A

Rationale: The correct answer is A: New set of tracheostomy tubes and Oxygen tank. Rationale: 1. New set of tracheostomy tubes: Essential for reinserting the cannulas to secure the airway. 2. Oxygen tank: To ensure James has a stable oxygen supply while the tracheostomy tubes are being reinserted. Summary of incorrect choices: B: Theophylline and Epinephrine - These medications are not directly related to managing a dislodged tracheostomy. C: Obturator and Kelly clamp - While these are useful tools for tracheostomy care, they are not the immediate equipment needed in this emergency situation. D: Sterile saline dressing - This is not relevant for a dislodged tracheostomy; the priority is securing the airway.

Correct Answer: A

Rationale: The correct answer is A: Removal of the transplanted kidney. Hyperacute rejection is a severe and immediate immune response to the transplanted organ. In this case, the transplanted kidney must be removed promptly to prevent further complications, as it is irreversibly damaged. High-dose IV cyclosporine (B) is used for immunosuppression but is not effective in treating hyperacute rejection. Bone marrow transplant (C) is not indicated for kidney rejection. Intra-abdominal instillation of methylprednisolone sodium succinate (D) is used for acute rejection, not hyperacute rejection.
