Step-by-step explanation:
The nurse assistant's first responsibility when admitting a resident would be to provide privacy. This ensures that the resident feels comfortable and respected. It also allows the nurse assistant to establish trust and create a safe environment for the resident.
While it is important for the nurse assistant to wash hands for infection control purposes, providing privacy takes priority in this situation. Introducing oneself and shaking hands can be done after privacy has been ensured.
Knocking on the resident's door is also important to respect their personal space, but it should be done after privacy has been established.
