What is the nurse's authority regarding the scope of tasks that can be delegated?

The correct choice accurately reflects the fundamental role that state laws and regulations play in defining the nurse's authority to delegate tasks. According to Washington State law, registered nurses (RNs) are responsible for determining which tasks can be safely delegated based on the specific parameters set forth by state regulations. This ensures that delegation is done responsibly and safely, taking into account the nursing process, client safety, and the complexity of the tasks involved.

State laws outline what tasks are permissible for delegation, emphasizing the nurse's responsibility to assess the situation and make informed decisions. This legal framework helps protect both the patient and the caregiver by ensuring that only appropriately trained individuals are tasked with specific responsibilities.

Other options suggest varying sources of authority for delegation. However, personal preferences, just facility policies, or individual capabilities alone do not encompass the comprehensive legal and ethical guidelines established by state regulations, which are critical in the delegation process.
