Which tasks can the RN delegate to unlicensed assistive personnel regarding a client with tuberculosis on airborne isolation?

The correct choice of posting signs for airborne isolation precautions on the door aligns with the responsibilities that can be delegated to unlicensed assistive personnel. This task involves a straightforward action that does not require clinical judgment or specialized knowledge, making it appropriate for delegation. Unlicensed assistive personnel can carry out this task under the direction of the registered nurse, as it primarily aims to inform and protect others by communicating the necessary precautions without needing complex clinical reasoning.

In contrast, tasks that require a higher level of understanding or the ability to provide explanations, such as explaining the reasons behind certain precautions or discussing the implications of airborne isolation with family members, require the critical thinking and clinical judgment of a registered nurse. Therefore, these tasks cannot be appropriately delegated to unlicensed personnel and are better suited for a licensed professional, who can provide comprehensive education and support.

Alerting the x-ray department about precautions may also involve communication that requires an understanding of clinical implications, making it less suitable for delegation.
