Explanation

Hand washing is the single most important and initial action to prevent the transmission of microorganisms and reduce the risk of surgical site infections (SSIs).
It is the first step in any aseptic technique, performed before gathering supplies or touching the patient and their environment.
This aligns with the World Health Organization's (WHO) guidelines on hand hygiene to ensure patient safety.
According to standard procedure, the nurse performs hand hygiene before and after the dressing change.

Option A: Removing the old dressing is a later step in the process, performed after initial hand hygiene and donning clean gloves.
Option B: Arranging sterile supplies should only be done after performing hand hygiene to avoid contaminating the sterile packaging.
Option D: Wearing clean gloves to remove the old dressing is a correct step, but it must be preceded by hand washing.

Clinical Relevance

Nursing practice connection: Safe nursing care depends on performing Aseptic technique and infection control during a surgical dressing change in the correct sequence, documenting the action clearly, and monitoring for the expected response.
Failure to perform hand hygiene is a leading cause of healthcare-associated infections (HAIs), which increase patient morbidity, mortality, and healthcare costs.
Nurses must differentiate between using clean gloves (for removing soiled dressings) and sterile gloves (for applying new dressings) to maintain asepsis.
What if? If the patient has a known multi-drug resistant organism (MDRO) like MRSA, contact precautions are initiated. The first step of hand washing remains the same and is even more critical. The nurse would also need to wear a gown and ensure proper disposal of all contaminated materials.

How to Approach the Question

Identify the question type: This is a process-based question asking for the 'first' step in a clinical procedure.
Recall the fundamental principles of infection control and aseptic technique. The primary rule is to prevent contamination.
Analyze the options by mentally sequencing the entire dressing change procedure.
Ask yourself, 'What is the absolute first action required to ensure patient safety and prevent infection before any other step can be taken?'
Eliminate options that are clearly later steps (like removing the dressing) or preparatory steps that must follow an initial action (like opening sterile supplies).
Select the option that represents the most foundational and universally required first step for preventing infection, which is hand hygiene.
