Which statement about wearing gloves is true?

Wearing gloves is an essential infection control practice in healthcare settings, particularly for certified nursing assistants. The statement regarding changing gloves before contact with mucous membranes is accurate because it emphasizes the importance of preventing cross-contamination and maintaining aseptic technique.

Mucous membranes are highly susceptible to infections, and the proper protocol is to wear fresh gloves each time you anticipate coming into contact with these areas. This action helps protect both the patient and the healthcare worker from potential pathogens that could be transmitted through bodily fluids.

The other options highlight common misconceptions or improper practices. Disposable gloves are designed for single use and should not be washed or reused, as that could introduce contaminants. Furthermore, gloves can easily become contaminated after patient care, and wearing torn gloves is not acceptable as it compromises the barrier they provide. Therefore, adhering to the guideline of changing gloves specifically before handling mucous membranes is vital for maintaining a safe and hygienic environment for both caregivers and patients.
