What task should the RN perform first?

The correct answer is to assess a newly admitted client first. When a client is newly admitted, it is crucial to perform an assessment promptly. The initial assessment and establishment of a care plan should be completed within a specific timeframe to ensure the client's needs are met effectively. Choices A, B, and C involve important tasks but should be prioritized after the initial assessment of the newly admitted client to ensure timely and appropriate care delivery. Changing a burn dressing (Choice A) and doing pinsite care on a client in skeletal traction (Choice B) are time-sensitive tasks but can be safely delayed briefly to conduct the initial assessment. Teaching a newly diagnosed diabetic about diet and exercise (Choice C) is important for the client's long-term care but can be scheduled after the immediate needs assessment of the newly admitted client.
