What is the correct action for a nurse to take before performing a dressing change on a client?

Washing hands thoroughly is a fundamental practice in infection control and is critical before performing any procedure, including a dressing change. This action helps to eliminate pathogens that could potentially be transferred to the client during the dressing change, thereby reducing the risk of infection. Hand hygiene is a key component of safe nursing practice and is emphasized in the guidelines for infection prevention.

While administering pain medication, preparing a sterile field, and informing the client about the procedure are also important steps to consider, they occur after hand hygiene has been performed. Other steps may involve ensuring the client is comfortable and understands the procedure, but none of these actions substitute the necessity of clean hands prior to coming into contact with the client's wound. Prioritizing hand washing sets a standard for safety and professionalism in the clinical setting.
