Final answer:
The nurse must ensure that when delegating a task to UAP, it is performed safely and accurately, which involves supervision, guidance, and verifying patient's response, making Option A correct.
Step-by-step explanation:
When delegating a nursing task to Unlicensed Assistive Personnel (UAP), the nurse is always accountable to ensure the task was performed safely and accurately. This means that the nurse must consider patient safety as the top priority, oversee the task as necessary, and verify the patient's response or condition following the intervention to ensure appropriate care was delivered and to make any necessary adjustments. It is not adequate for a nurse to delegate a task without providing supervision or guidance (Option B is incorrect), without verifying the patient's response or condition (Option C is incorrect), or to prioritize speed over safety measures (Option D is incorrect). Consequently, the correct option in this scenario is Option A.
