During a sterile dressing change for a client with infected deep partial-thickness burns of the chest and abdomen, arrange the steps in the correct order: 1. Apply silver sulfadiazine (Silvadene) ointment. 2. Obtain specimens for aerobic and anaerobic wound cultures. 3. Administer morphine sulfate 10 mg IV. 4. Debride the wound of eschar using gauze sponges. 5. Cover the wound with a sterile gauze dressing.

• C. 3, 2, 4, 1, 5
• D. 3, 4, 1, 2, 5

Answer: (A)

The main idea here is to prepare the wound in a way that is painful but safe for the patient, while also ensuring accurate diagnostic sampling before antimicrobial agents are applied. Start with analgesia so the patient can tolerate the procedure without guarding the area, which helps when performing a careful, thorough debridement. Then perform mechanical debridement to remove necrotic eschar and loosen debris; this step both reduces microbial load and exposes viable tissue for assessment and sampling. After the wound bed is prepared, obtain specimens for aerobic and anaerobic cultures from the wound to guide therapy—doing this before applying topical antimicrobial agents helps ensure the culture results aren’t contaminated or inhibited by the agent. Once the cultures are drawn, apply the topical antimicrobial ointment (silver sulfadiazine) to provide antimicrobial coverage across the wound. Finally, cover the wound with a sterile gauze dressing to maintain a clean, protected environment and promote healing.

Choosing a different order would compromise either pain control, wound bed preparation, or the accuracy of culture results—for example, applying the antimicrobial before obtaining cultures can alter or mask the organisms present, and performing debridement or cultures without analgesia can make the procedure unsafe or intolerable for the patient.
