While the client's full-thickness burn wounds to the face and body are exposed, what is the best nursing action to prevent cross-contamination?

Choice A reason: Full-thickness burns disrupt the skin barrier, increasing infection risk. Wearing gowns, caps, masks, and gloves creates a sterile barrier, preventing cross-contamination from healthcare workers or the environment. This adheres to strict infection control protocols, minimizing the introduction of pathogens like Staphylococcus or Pseudomonas to vulnerable burn wounds. Choice B reason: Increasing room temperature to 70°F (20°C) during dressing changes aims to prevent patient hypothermia, as burns impair thermoregulation. However, this does not directly address cross-contamination. Temperature control is supportive but does not reduce microbial transmission, making it less effective than personal protective equipment for infection prevention. Choice C reason: Using sterile gloves when removing old dressings reduces contamination during that specific task. However, it is less comprehensive than full personal protective equipment (gowns, caps, masks, gloves), which protects against contamination throughout care. Sterile gloves alone do not cover potential pathogen spread from other sources, like respiratory droplets or clothing. Choice D reason: IV antibiotics treat or prevent systemic infections but do not directly prevent cross-contamination of exposed wounds. Prophylactic antibiotics may reduce bacterial colonization but are not the primary method for preventing environmental or contact-based contamination, which is better addressed by physical barriers like gowns and gloves.
