Final answer:
The statement indicating the need for additional teaching is that UAPs can assess vital signs during the initial minutes of a blood transfusion. Proper delegation requires certain tasks, like the administration of dopamine, to be performed under a registered nurse's supervision or by someone with specific advanced training.
Step-by-step explanation:
The statement made by an RN that indicates the need for additional teaching is: "Unlicensed assistive personnel (UAP) can assess vital signs during the first 5 minutes for a patient who is receiving a blood transfusion because a reaction at this time is unlikely." This assessment needs to be performed under the direct supervision of a registered nurse due to the critical nature of the transfusion process.
The statements regarding the LPN/LVN administering a PPD if there is no history of a positive PPD, and transferring a patient to the bed from the wheelchair with proper training and competency are appropriate tasks for them to perform. The statement on delegating responsibility to the UAP while retaining accountability aligns with proper delegation principles. However, the LPN/LVN administration of dopamine requires enhanced training and the ability to make clinical assessments which are typically beyond their scope, thus indicating a need for additional teaching on this matter.
