Explanation

The care of a client with a new diabetes diagnosis requiring initial, comprehensive teaching about insulin administration and management is complex and falls under the scope of practice of an RN. An experienced RN from the unit possesses the necessary assessment, critical thinking, and teaching skills, as well as familiarity with unit protocols for diabetes management, making them the most appropriate choice for this complex assignment.

While an experienced LPN/VN can monitor glucose levels and administer insulin to stable clients, initial comprehensive teaching is an RN function. A newly graduated RN is still developing their skills and requires supervision, making this complex assignment inappropriate during early orientation. A float RN from a specialized area like labor and delivery may not have recent experience or expertise in managing acute diabetic care and providing initial, in-depth education.
