Aclinic nurse has observed another nurse deviating from agency policy in performing wound care. the best approach for the clinic nurse to take is to:

First, try to talk to the nurse in private. Do not be accusatory, just remind them of the agency policies regarding wound care, & talk about what you observed and emphasise the wish to help, not criticise. If they are antagonistic and/or do not amend their wound care practice, then it will be necessary to speak with your supervisor about the matter. Ultimately, the duty of care to your patients is more important than one nurse's pride.
