Final answer:
Giving mouth care requires a nursing assistant to wear gloves to prevent the transmission of infections, adhering to infection control protocols.
Step-by-step explanation:
Giving mouth care is indeed a task that requires a nursing assistant to wear gloves. When performing mouth care, the assistant is exposed to bodily fluids such as saliva, which may contain pathogens. Using gloves is a fundamental aspect of infection control and helps to prevent the transmission of potential infections between the healthcare provider and the patient. It is important for nursing assistants to adhere to standard precautions and utilize the appropriate personal protective equipment (PPE) when providing any form of patient care that involves contact with mucous membranes or bodily fluids, including mouth care.
