A nurse is reviewing the BUN result of a client who is taking cyclosporine following a kidney transplant. Which of the following laboratory studies should the nurse recognize as another renal function study that should be monitored?

Choice A reason: Obtaining initial assessments requires clinical judgment and is outside the scope of assistive personnel (AP). Registered nurses must perform assessments to identify health changes accurately. Delegating this task violates scope of practice regulations, making it illegal and unsafe for AP to perform.
Choice B reason: Changing a nonsterile dressing is within the scope of assistive personnel, as it involves routine, non-invasive care under nurse supervision. AP are trained for such tasks, which do not require clinical judgment, making this a legal and appropriate delegation choice.
Choice C reason: Interpreting laboratory results requires advanced knowledge and clinical decision-making, reserved for registered nurses or providers. Assistive personnel lack the training to analyze results, so delegating this task is illegal and risks patient safety, making it an incorrect choice.
Choice D reason: Educating clients and families involves assessing learning needs and tailoring information, which requires nursing judgment. Assistive personnel are not trained for patient education, making this task outside their scope and illegal to delegate, thus an incorrect choice.

Choice A reason: Saturated sanguinous drainage post-reinforcement signals excessive bleeding, potentially indicating hemorrhage or poor wound healing. Two hours postoperative, this suggests vascular injury or coagulopathy, requiring urgent provider notification to prevent hypovolemia, infection, or further complications in the surgical site.
Choice B reason: Oxygen saturation of 96% on 2 L/min nasal cannula is normal (95-100%), indicating stable respiratory status. This does not require reporting, as it reflects effective oxygenation post-surgery, with oxygen therapy appropriately supporting recovery without signs of respiratory distress.
Choice C reason: A pain level of 2/10 post-medication indicates effective pain control, not warranting immediate reporting. Postoperative pain management targets comfort (<4/10), and this level suggests successful analgesia, with no evidence of complications like nerve injury requiring provider intervention.
Choice D reason: Urine output of 50 mL/hr is normal (>30 mL/hr) post-catheter removal, indicating adequate renal perfusion. This does not require reporting, as it reflects normal kidney function and hydration status in the early postoperative period, absent other concerning symptoms.
