Step-by-step explanation:
The intervention within the RN scope of practice from the given options is administering blood transfusions. Performing surgical procedures is typically the responsibility of a surgeon and not within the traditional scope of nursing practice. Interpreting diagnostic imaging results is generally conducted by radiologists or other physicians. Providing health education and counseling is also a key part of the RN's role and is often included in nursing protocols and best practice guidelines.
Specific tasks include reviewing patient history and current condition, assessing and responding to patient needs before, during, and after treatment, and ensuring accuracy and sterility in procedural setups. The focus of nursing often includes aspects such as ensuring that all surgical items are accounted for, that specimens are correctly labeled, and addressing any issues with equipment.
