In which situation should a nurse obtain a new pair of gloves while caring for a client?

Obtaining a new pair of gloves after changing a dressing and before documenting findings is critical for maintaining infection control practices. This ensures that any potential contamination from the dressing change does not spread to the documentation tools or the nurse's skin.

Once gloves are removed after a procedure like dressing changes, they should be discarded, as they may be contaminated with pathogens. This step helps to minimize the risk of transmission of infections, particularly in a healthcare setting. Documenting findings typically involves writing on a chart or using a computer, which could also become contaminated if gloves from a dirty procedure are worn.

The other scenarios do not require the immediate need for a new pair of gloves the same way as changing a dressing does. For example, performing hand hygiene is already a step to reduce contamination risk. Entering a client's room does not necessarily involve touching any contaminated materials, and leaving the room does not require changing gloves unless coming into direct contact with a new or different patient or item susceptible to contamination.
