Final answer:
When a nurse picks up a client's contaminated tissue without gloves and fails to wash the hands sufficiently, the nurse provides for the client's organisms to be spread by contact transmission.
Step-by-step explanation:
When a nurse picks up a client's contaminated tissue without gloves and fails to wash the hands sufficiently, the nurse provides for the client's organisms to be spread by contact transmission. Contact transmission refers to the transfer of an infectious agent between hosts through contact with a contaminated surface or object, also known as a fomite. In this case, the contaminated tissue is the fomite that can transmit the organisms to others through direct contact.
