Step-by-step explanation:
The most important instruction the nurse will give to the caregiver is to wash your hands frequently. Washing hands frequently is an essential practice to prevent the transmission of infections, including AIDS. It helps remove pathogens that may be present on the hands and reduces the risk of spreading them to others or to surfaces.
To properly wash hands, the caregiver should use soap and water and scrub all surfaces of the hands for at least 20 seconds. This should be done before and after any activity that involves contact with the client or surfaces in the home.
